ABSTRACT

This atlas presents information on fish eggs and temperature data collected from

broadscale ichthyoplankton surveys conducted off the U.S. northeast coast from 1977 to

1987. Distribution and abundance information is provided for 33 taxa in the form of graphs

and contoured egg-density maps by month and survey. Comments are included on interannual

and interseasonal trends in spawning intensity. Data on 14 additional but less numerous

taxa are provided in tabular form.

Introduction

The Northeast Fisheries Science Center (NEFSC) conducted a comprehensive fisheries ecosystem study in

coastal waters off the northeastern United States from

1977 through 1987. Known as MARMAP (Marine Resource Monitoring Assessment and Prediction), the

study included standardized year-round collections of

fish eggs and larvae that provide baseline information

on the distribution of eggs to determine spawning times

and locations, as well as the abundance and variety of

fish eggs and larvae (Sherman, 1980). Since these results are based on nine, and for some species, as many

as eleven years of data, generalizations based on these

collections are robust.

The distribution and abundance data of pelagic fish

eggs provide the best available information on spawning areas, times, and intensities; long-term data can provide information on seasonal and annual changes in

spawning intensity and areas. Correlation of such data

with environmental parameters will lead to definition

of essential habitat for early life stages. It will also improve our understanding of those factors contributing

to fluctuations in year-class strength and, when compared with the relative abundance oflarval andjuvenile

fish, will lead to more knowledge about early life-stage

survival. The purpose of our atlas is to describe distribution patterns of fish eggs for the 33 principal taxa collected, and to provide summary notes on an additional

14 taxa. This atlas is the fourth in a series of publications which summarize data from the MARMAP program. Previous atlases have reported on survey design

and methodology (Sibunka and Silverman, 1984, 1989)

and larval fish distributions (Morse et aI., 1987).

Methods

MARMAP surveys were conducted at monthly to bimonthly intervals from 1977 through 1987 (Table 1).

The study area included continental shelf waters from

the northern Gulf of Maine and western Scotian Shelf

to Cape Hatteras, orth Carolina-an area of approximately 260,000 km2 . Based on ecological considerations

described by Sherman (1980), the survey area was divided into four subareas: the estuarine-influenced waters of the Middle Atlantic Bight, the broad continental

shelf waters over a gently sloping bottom off southern

New England, the relatively shallow, well-mixed waters

of Georges Bank, and the deep, seasonally-stratified

waters of the Gulf of Maine (Fig. 1). Data for this study

were collected on standardized MARMAP surveys and

on those dedicated to assessing the status ofjuvenile and

adult fish or molluscan populations. The latter were only

secondarily concerned with plankton collections. Station locations for standardized MARMAP surveys varied

little between surveys except that a few deep-water sites

occupied during the first two years were subsequently

omitted. Additional stations were added to increase sampling intensity at selected sites, mostly in 1987 as part of

an intensive study to assess Atlantic mackerel spawning.

There were 214 standard station locations visited during all 81 surveys over the II-year period. Nine deepwater locations sampled during the first two years and

four non-transect locations in close proximity to others

(<12 km distant) were omitted, leaving a total of 201

standard locations to be considered here. Stations were

located along and between 7 transects. Those along the

transects were spaced at 8 to 18-km intervals, others at

25 to 35-km intervals (Fig. 1). Plankton sampling locations on trawl and dredge surveys were selected from

stratified random station plans that changed with each

survey (Grosslein, 1969). Ichthyoplankton sampling intensity on trawl and dredge surveys was similar to that

on dedicated plankton surveys, i.e. stations were approximately 25 to 35 km apart.

Plankton was sampled with a 61-cm bongo fitted with

0.505 and 0.333-mm mesh nets and weighted with a 45-

kg lead ball. The 0.505-mm side was used for most

ichthyoplankton collections, while the 0.333-mm side

was used primarily for zooplankton collections; it also

provided replacement samples of ichthyoplankton in

summarize data for these graphs. Monthly egg densities

were composites of data across all years. Survey mean

densities were based on all tows in a given survey and

did not attempt to compensate for variability in sampling coverage between surveys. Surveys failing to sample

the entire MARMAP area, either by design or due to

severe weather or vessel breakdowns, can introduce bias

in the resulting mean egg density data, and graphs based

on these surveys should be viewed with this in mind.

There are a few instances where the calculated mean

dates of occurrence for two adjacent surveys are so close

in time that one of the histogram bars is obscured by

the other member ofthe pair. There are several instances

where the calculated mean density is such a low value

(relative to the maximum displayed) that it is not visible; it is not displayed by the graphing software. And,

similarly, there are many low-density values which are

displayed but appear as very small dots. In both of these

cases of low density, survey maps are included which

show the areal occurrence of the species in question,

even if densities are not visible on the histogram.

Temperature observations at plankton stations were

obtained from surface waters by bucket thermometer

and, at depth, from expendable bathythermograph

(XBT) drops, conductivity-temperature-depth (CTD)

casts, or reversing-thermometers on Niskin-bottle casts.

Mean values for 0-15 m and 0-200 m depth intervals

were calculated for each station. These were weighted

pling was conducted to within 5 m of the bottom to a

maximum of200 m. Vessel speed was maintained about

2.8 km/hr (1.5 kt).

Plankton samples were fixed and preserved (5% formalin seawater solution). All fish eggs were removed

from the 0.505-mm mesh samples, identified, and separated into developmental stages. Three stages were used:

1) from just spawned to just before blastopore closure,

2) from blastopore closure to just before the tail bud

lifts free from the yolk surface, and 3) from tail bud

free tojust before hatching. When large numbers of eggs

were collected, subsamples were taken for staging purposes. We used two levels of subsampling that allowed

for more precise estimates of egg stages for targeted

species, and which were to be considered for future

analysis. A maximum of500 eggs were staged if the taxon

was Cynoscion regalis, Gadus morhua, Pleuronectes

ferrugineus, Melanogrammus aeglefinus, Merluccius bilinearis,

Paralichthys dentatus, Pomatomus saltatrix, Peprilus

triacanthus, Pollachius virens, or Scomber scombrus. Approximately 100 eggs were staged for other taxa.

Identification of fish eggs is difficult because there

are fewer morphometric and meristic features available

for identification than there are for larvae andjuveniles.

Some identifications can only be made to genus or family level because of the absence of distinguishing features. While several features are relatively constant

throughout egg development, there can be some degree of overlap or commonality among unrelated taxa

with respect to these features. These features include

egg diameter and shape; number and size of oil globules; size of perivitelline space; nature of yolk, whether

homogeneous or segmented; and nature of chorion

surface, whether smooth, pitted, or sculptured. Certain

taxa with similar size eggs could not be distinguished at

certain developmental stages (Table 2). To identify eggs

within these groupings we applied proportions noted

among later, identifiable stages to the numbers of earlier, inseparable stages at the same or neighboring station. All catches were standardized to number of eggs

sampled per 10 m2 of sea surface area (Smith and

Richardson, 1977).

Maps depicting contoured egg densities (no./10 m2

of sea surface area) were computer generated using

Surface III software (Sampson, 1988) and interpreted

and enhanced by a Fortran program that produced bitmap (PCX-format) output files for printing purposes.

Monthly egg-density contour maps were created by averaging tow densities (no./10 m2) at each standard station, then plotting the resulting mean density at the

weighted mean location. These locations were weighted

by individual tow densities.

Mean egg densities (no./10 m2), by month and by

survey, were graphed for each of 33 taxa. Delta-means

(Pennington, 1983; Berrien et aI., 1984) were used to

depth interval extending halfWay to adjacent observations. Survey mean values were calculated for three depth

regimes (surface, 0-15 m, and 0-200 m). Expected mean

values were derived for the ll-year series using methods

described by Mountain (1989) and deviations from the

long-term mean were calculated for each survey.

Results

There were 81 MARMAP surveys in all, conducted between February 1977 and December 1987, however, a

lesser number of surveys were analyzed for fish eggs.

Plankton samples from several surveys, both unexamined and partially examined, were lost in a laboratory fire. For most species considered here, samples from

68 surveys (nos. 12 to 50 and 53 to 81) were examined.

In addition, egg samples from surveys 1 to 5 were examined for Scomberscombrus and Pleuronectesferrugineus eggs.

A total of 9,478 plankton samples collected during 68

surveys were examined for fish eggs; these numbers

change to 10,273 samples and 73 surveys when samples

partially sorted and identified are included. AJI identified taxa are listed along with additional information

including numbers caught, frequency of occurrence,

and seasonal and areal summaries of occurrence (Table

3). More than 1.8 million fish eggs, belonging to 47

known taxa, 67 unknown but distinct types, and the category "unidentified," were collected during MARMAP

surveys. Information for 33 selected taxa is shown in

graph and map form, accompanied by briefstatements

summarizing seasonal distribution and abundance.

These 33 taxa comprise 97.8% of all eggs collected. Four

taxa were clearly dominant: Anchoa mitchilli, Scomber

scombrus, Urophycis spp., and Merluccius bilinearis. Together they comprised 60% of all eggs collected during

the 68 surveys fully sorted and identified. Maps of contoured egg densities are given for all surveys on which a

given taxon was caught. These data are also summarized

by monthly plots which illustrate seasonal changes in

geographic distribution of eggs during a composite average year. Monthly plots of sampling effort (number

of tows per location) are given to aid interpretation of

monthly distribution maps (Fig. 2). An additional 14 taxa

appear only in Table 3. These were not sufficiently abundant or adequately sampled to warrant a more detailed

presen tation.

Temperature data associated with plankton tows are

presented in graph and tabular form (Fig. 3-5; Append.

Table 1). Graphs summarize survey means, ±l standard

deviation (SD), and anomalies of sea surface, 0-15 m,

and 0-200 m depth ranges. Interannual trends illustrated by anomalies show that shelf waters tended to be

lower in temperature during 1977 to 1982 than the longterm average, were above average from 1983 to 1986,

and below average in 1987. These trends were evident

in data from the three depth regimes noted above. Similar trends are evident in data from a study by Mountain

and Manning (1994-Fig. 8) covering the same years

(1977-87) at four sites in shelf waters between Georges

Bank and Virginia, although they are not evident for

sites within the Gulf of Maine. These authors noted that

sites southwest of Georges Bank exhibit a higher degree

of correlation in temperature anomalies than sites in

the Gulf of Maine, implying regional scale influences.

Differences in "N", the total number of catches examined for fish eggs (Table 1) vs. the number of temperature observations (Append. Table 1), the number

of stations sampled (Sibunka and Silverman, 1984,

1989), or the number of catches examined for fish larvae (Morse et aI., 1987), are due to loss of egg or larva

samples, or lack of temperature data at given stations.

The following are summaries of data on individual

species (taxa).

Dphichthus cruentifer, margined snake eel

(Figs. 6-8)

Ophichthus crumtifereggs were caught during 11 mon ths

of the year,January to November, but were most abundant in July to September, indicating predominantly

summer spawning (Fig. 6). Most were collected in outer,

deeper portions ofshelf waters between Cape Hatteras

and southern Georges Bank,

There was an extended period of minimal spawning

(October to May) followed by increased spawning in

June ofsome years and by July in all years (Fig. 7), Eggs

were first collected in isolated patches, usually in the

extreme southern part of the Middle Atlantic subarea,

followed by collections encompassing a broad area of

outer shelf waters, from Cape Hatteras to southern

Georges Bank. This increased spawning continued into

August then rapidly reverted back to minimal activity

by October.

Figure 9

B-revoortia tyrannus; mean-egg-density graphs by month

(top) and by survey (bollom) for the total MARMAP

area. (*Samples from the first four surveys in 1978 were

not analyzed for B. tyrannus eggs.)

Brevoortia tyrannus eggs were collected from May to November and in January. The frequency distribution of

mean egg abundance was distinctly bi-modal, with peaks

in spring and autumn (Fig. 9). Most B. tyrannus eggs

were taken in nearshore continental shelf waters.

The peak in spring (May to July) indicates spawning

began in southern New England waters, then rapidly

spread into western Gulf ofMaine duringJune, and sub--

sided in July. The second and more protracted spawning period occurred from late summer to early winter

in southern New England and Middle Atlantic areas.

This spawning began in central Middle Atlantic waters

in August and spread during September to November

throughout inshore waters from Nantucket Shoals to

Chesapeake Bay and southward. Spawning rapidly subsided and ended by January in southern Middle Atlantic waters (Fig. 10). The lack of B. tyrannus eggs in December probably reflects a lack ofsampling in southern

Middle Atlantic waters during that month (Fig. 2).

Egg abundance increased over the 9 years ofMARMAP

egg surveys (Fig. 9). Brevoortia tyrannus eggs were most

abundant from 1984 to 1987 in both northern and southern spawning areas noted above (Fig. 11).

Figure 11 (continued)

Anchoa hepsetus, striped anchovy (Figs. 12-14)

Anchoa hepsetus eggs were collected from April through

September, with peak abundance occurring in May and

June (Fig. 12). Although eggs of this species were not as

abundant as eggs of the congener A. mitchilli (Figs. 15-

] 7), these species shared similar spatial and temporal

spawning habits. Eggs occurred predominantly inshore

from Cape Hatteras to NewJersey, but ranged north and

east to inner shelf waters off Narragansett Bay (Figs. ]3

and 14).

Spawning began as early as April near Cape Hatteras,

then progressed northward as far as Delaware Bay during May and to inshore southern New England waters

in July. Thereafter eggs were found in relatively restricted

areas into September.

Anchoa mitchilli, bay anchovy (Figs. 15-17)

Anchoa mitchilli eggs, the most abundan t taxon collected,

occurred predominantly in inner shelf waters of the

Middle Atlantic and southern Ne-,.v England subareas

during April through October, with peak abundances

occurring inJune orJuly (Fig. 15). The highest densities occurred close to shore, as would be expected for

this estuarine species. Eggs were not collected east or

north of Nantucket Shoals. Although the peak density

in June (Fig. 15) was influenced strongly by collections

from one survey in 1979 (no. 17), several tows contributed to this peak. If 1979 data were omitted, peak mean

egg density would change to the month ofJuly.

Based on occurrences of A. mitchilli eggs, spawning

starts as early as April near Cape Hatteras, then rapidly

expands northward in inner shelf waters through May

and June, occurring as far north and east as Long Island, and occasionally to Narragansett Bay in July (Figs.

16 and 17). Between September and October spawning

declined and appeared sporadic.

(top) and by Sllrvcv (bottum) for the total MARMAP

area. (*Samples from the first four surveys in 1978 were

not analv/ed for .'\11. //IUI'//en eggs.)

Maurolirus mupllerz e?;gs were collected throughout the

year. A seasonal cycle in eg?; abundance was apparent

with a minimum from February to April and a maximum from September to ovember (Fi?;. 18). E?;gs of

this mesopelagic species occurred primarily in shelf edge

waters. Occasionally, during September to Dec ember,

eggs were collected in isolated locations in western Gulf

of Maine, northwestern Ceorges Bank, and southern

;'\lew England waters (Fig. 19).

E?;gs occurred in isolated locations alon?; the shelf

ed?;c of Middle Atlantic, southern New En?;land, and

Georges Bank subareas dllfing the period of T'linimal

spawning from February to ApriL As spawn in?; ?;radually increased from May to Au?;ust, eggs occurred in thf'se

same areas, but more frequently and in somewhat

greater numbers. With highest egg densities in Septf'mher, eg?; distribution was almost continuous al\lIl?; the

shelf ed?;e from off Capf' Hatteras to southf'astern

Georges Bank, and in scattered locations in Ceorges

Bank and Gulf of Maine suhareas (Fi?;. 19). Thereafter,

mean monthly egg densities decreased while spawning

diminished in intensity along the shelf edge. Mean egg

densities during August, October, and Decemher were

probably underestimated due to incompkte co\'erage

of shelf edge waters.

There appeared to he an upward trend in M. mueflm

spawning levels over the years sampled (Fig. IR). However, only the inner portion of the apparent spawning

area was sampled.

Figure 20 (continued)
48 NOAA Technical Report 145 _

Brosme brosme, cusk (Figs. 21-23)

BrOSfl~e llrosme eggs occurred primarily In the Gulf of

Maine and Georges Bank subareas and occasionally in

southern New England and Middle Atlan tic waters (Fig.

22). They were collected from March to November and

were most abundant in late spring and summer (Fig.

21) .

Spawning began in some years as early as March, but

more often in April. Eggs occasionally occurred along

the shelf edge as far south as Virginia and Maryland,

but more commonly along the southern and eastern

portions of Georges Bank, and at scattered locations in

the Gulf of Maine. During May and June spawning increased, with eggs occurring extensively throughout the

Gulf ofMaine subarea and over the southern portion of

Georges Bank. Spawning simultaneously declined

throughout all areas from July to November.

The high egg densities in 1983 (survey 43) do not

appear related to bias in sampling coverage. The entire

MARMAP area was sampled during that survey without

bias to any particular subarea or location (Fig. 23).

Enchelyopus cimbrius, fourbeard rockling

(Figs. 24-26) 60

so -; By Month

EncheLyopus cimbrius eggs were collected throughout the

year. From May to September they were commonly collected north and east of New Jersey, and were partiClIlarly abundant in western Gulf of Maine, peripheral

Georges Bank, and southern New England waters. Although eggs occurred year round, there was a marked

seasonal cycle in abundance with a peak inJune and a

minimum from October to March (Fig. 24). Eggs mainly

were collected in deep water in winter months and in

shallower waters during summer (Fig. 25).

Spawning was at a minimum in February, and eggs

were restricted to isolated locations near the shelf edge

of southern New England and Middle Atlantic waters

(Fig. 25). The spawning area expanded from March to

May, particularly in southern New England and Gulf of

Maine waters, and in deeper portions of Georges Bank.

Peak spawning occurred in June with the majority of

eggs occurring in western Gulf of Maine. Spawning declined throughout the area from midsummer through

autumn and egg distribution became increasingly patchy

(Figs. 24 and 25).

Gadus morhua, Atlantic cod (Figs. 27-29)

Figure 27

Gadus morhua; mean-egg-density graphs by mon th (top)

and by survey (bottom) for the total MARMAP area.

(*Samples from the first four surveys in 1978 were not

analyzed for G. morhua eggs.)

Gadus morhua eggs were one of the most common species collected (Table 3). Although occurring year-round,

they exhibited a pronounced annual cycle of abundance

(Fig. 27). Eggs were found over a wide geographic area

from Nova Scotia southward almost to Cape Hatteras.

Their cen ter of abundance was in western Gulfof Maine,

Georges Bank, and southern New England waters. They

were taken primarily at locations where the water depth

was <l00 m, but occurred at virtually all water-column

depths sampled.

Egg densities were minimal during August and September (Figs. 27 and 28). During autumn and winter,

spawning increased and expanded in areal distribution

throughout the GulfofMaine, Georges Bank, and southern New England subareas. Maximum average abundance occurred in March with highest densities occurring on Georges Bank (Figs. 27 and 28). A large part of

the Gulf of Maine was not sampled in March, when geographic distribution and egg densities were probably at

peak levels in that subarea. Throughoutspring and early

summer, spawning decreased and by late summer was

reduced to isolated areas in Gulf of Maine and Georges

Bank waters (Fig. 28).

A downward trend in egg abundance was observed

over the nine-year sampling period (Fig. 27). The very

high abundance for Survey 21 in 1980 (mean density =

294/10 m2) resulted largely from a single catch of eggs

which comprised 46% of all Atlantic cod eggs taken over

the entire sampling period.

Figure 30

Melanogrammus aeglefinus; mean-egg-density graphs by

month (top) and by survey (bottom) for the total

MARMAP area.

Melanogrammus aeglefinus, haddock

(Figs. 30-32)

Melanogrammus aeglefinus eggs were collected from January to August, and were most abundant in April (Fig.

30). They occurred on Nantucket Shoals and adjacent

waters, Georges Bank, the Scotian Shelf, and in the Gulf

of Maine. Eggs collected during March 1984 indicated

that in some years spawning occurred as far south as

southern New Jersey (Fig. 32). Abundance and distribution of eggs in the Gulf of Maine and Scotian Shelf

during March is unknown as we did not sample much

of those areas that mon th (Figs. 2 and 31).

Spawning began in January on the Scotian Shelf and

Georges Bank and was concentrated on the eastern portion of the Bank. As the season advanced, spawning increased in intensity and areal extent, occurring south

to Nantucket Shoals and north into the Gulf of Maine.

However, the major spawning area remained on eastern Georges Bank and Scotian Shelf. During June and

July spawning decreased dramatically and by August eggs

occurred only in isolated patches in coastal waters of

western Gulf of Maine (Fig. 31).

A downward trend in spawning intensity was observed

over the nine-year sampling period (Fig. 30). For the first

two years (1979 and 1980), mean egg densities exceeded

130/10 m2; during the remaining seven years (1981-87)

mean egg densities ranged from 19 to 60/10 m2. This decline in spawning was similar to that found for Atlantic

cod over the same time period (Fig. 27). While both

gadid species co-occur in the GulfofMaine and on Georges

Bank, their spawning seasons differ; Atlantic cod spawn

over a greater area and a longer season, and reach a peak

in spawning about one month earlier than haddock.

Merluccius albidus, offshore hake

(Figs. 33-35)

Merluccius albidus eggs were collected during all months

of the year, indicating year-round spawning, and were

most abundant from April to June (Fig. 33). They generally occurred along the outer, deeper portions of the

continental shelffrom eastern and southeastern Georges

Bank to off Chesapeake Bay.

While spawning intensity is cyclic, with a marked peak

from April to June (Fig. 33), there did not appear to be

a corresponding shift in areas of egg occurrence, either

on or off the shelf, or north or south along the shelf

(Fig. 34). The apparent secondary peak in egg abundance during October was most likely a sampling artifact. Many ichthyoplankton samples taken during July

and August were collected on shellfish assessment surveys that seldom sampled out to the shelf edge. Thus,

bi-modality in monthly egg densities reflected undersampling during July-September in areas where

Merluccius albidus eggs would most likely occur.

Spawning intensity declined during the nine years

surveyed. Mean egg densities exceeded 10/10 m2 during three of the first four full years surveyed (1979-82),

but remained below 5/10 m2, with one exception (in

1984) during the last five years. The relatively high mean

egg density observed in 1984 was influenced by collections taken during survey 50 where densities were high.

There was no apparent bias in sampling coverage during that survey to explain these high densi ties (Fig. 35).

Figure 36

Merluaius bilinearis; mean-egg-density graphs by month

(top) and by survey (bottom) for the total MARMAP

area. (*Samples from the firSI four surveys in 1978 were

nOI analyzed for M. bilinearis eggs.)

Merluccius bilinearis eggs were very abundant and one of

the most commonly occurring taxa (Table 3). They were

collected throughout the year, but were most abundant

from May to September, when mean densities over the

nine years exceeded 1,000/10 m2 at individual locations

(Figs. 36 and 37).

During winter months Uanuary to March) spawning

was restricted to deeper waters from southern Georges

Bank to off Chesapeake Bay. Spring warming during

April and June was accompanied by a dramatic increase

in spawning and a shift to mid-shelf and inner-shelf

spawning grounds from approximately Delaware Bay

and northward. South of Delaware Bay spawning was

concentrated in outer shelf waters year-round. Peak

spawning occurred during July and August on Georges

Bank and southern ew England waters; significant

spawning also occurred in Middle Atlantic and inshore

GulfofMaine waters during summer. Following theJuly/

August peak in egg abundance, spawning declined during autumn, and by December eggs were found in isolated locations along the shelf edge (Fig. 37).

An upward trend in spawning intensity was indicated

during the nine-year survey period (Fig. 36). This trend

was evident despite a probable upward bias for the two

highest mean egg densities observed (1984 and 1986),

caused by under-sampling in the Gulf of Maine.

Pollachius virens, pollock (Figs. 39-41)

Pollachius virens eggs were collected from October toJune

(Fig. 39) and were most abundant during winter, with

the highest mean egg densities occurring in December

and January (Fig. 39). Greatest numbers of eggs were

found on Georges Bank and in shallower waters ofwestern and eastern Gulfof Maine. Lesser numbers occurred

throughout the Southern ew England subarea and only

infrequently in the Middle Atlantic subarea (Figs. 40

and 41).

Spawning began in October at scattered locations on

Georges Bank and in the western and eastern portions

of the Gulf of Maine. During November spawning increased and became more widespread in those subareas. At peak spawning during December and January,

egg densities were concentrated in western Gulfof Maine

and Georges Bank waters. Eggs occasionally occurred

in the southern New England subarea as far west and

south as Hudson Canyon. The distribution of eggs continued to expand towards the southwest into February

and occasionally reached Delaware Bay. From March

through June spawning persisted, but at a diminishing

rate, with eggs occurring at increasingly isolated locations in the Gulf of Maine and on Georges Bank. Due to

a lack of sampling in most of the Gulf of Maine during

March, both the mean egg density and the egg distribution for that month are probably low and incomplete,

respectively.

Umphycis spp. eggs were the most frequently occurringand the third most abundant egg iden tified (Table 3).

They were collected during all mon ths of the year, in all

subareas, and occurred from shallow coastal waters to

out beyond the shelf (Fig. 43), A seasonal cycle of abundance was observed, with minimal numbers and the most

restricted geographic distribution observed in winter

and early spring, and the g-reatest abundance and winest distribution during summer (Figs. 42 and 43).

Umphycisspp. eggs in winter and early spring (December to April) occurred mainly in outer shelf waters of

the Middle Atlantic and Southern New Eng-Iann subareas (Fig-. 43). During spring- ann summer when shelf

waters were warming, egg concentrations shifted onto

the shelf throug-hout these two subareas, as well as onto

Ceorg-es Bank and into the Gulf of faine, particularly

the western portion. The process was reversed with late

summer and autumn cooling. From September to December egg abundances decreased and major concentrations of eggs shifted towards the outer shelf of the

\tliddle Atlantic and southern New Eng-land subareas.

With the exception of ] 983, a decrease in Vrophyris

spp. egg abundance was observed over the nine-year

sampling period (Fig. 42). Sun'C}' 44 in 1983, which produced the hig-hest mean egg density, lacked coverage ill

inshore Middle Atlantic waters and in eastern and central Gulf of Maine (Fig. 44); both areas of expected low

egg density. This would tend to bias the sampled meall

egg density.

Because these eggs were not identified to pecies, and

there are probably four species included in our "Lmphycis

Figure 45

Prionotusspp.; mean-egg-density graphs by month (top)

and by survey (bottom) for the total MARMAP area.

(*Samples from the first four surveys in 1978 were not

analyzed for Prionotus spp. eggs.)

Prionotus spp. eggs were collected throughout most of

the year and were most abundant during late summer

and absent only during February and December. The

two species considered are P carolinusand P evolarts, and

given that their spawning habits may differ, the two-species nature of the data may contribute to a dichotomy

in spawning area.

Spawning began in some years as early as March or

April in southern areas, but typically increased significantly in May. North of Chesapeake Bay in May, eggs

occurred both inshore and offshore (Fig. 46). During

any given May survey they tended to occur in one or the

other of these locations. However, in May 1985 they were

caught in both areas (Survey 60, Fig. 47). During June

andJuly, spawning increased in both area and intensity,

especially in the Middle Atlantic and inshore southern

New England subareas. Spawning extended onto

Georges Bank in at least three ofthe nine years surveyed

(Fig. 47). At the peak of spawning in August and September (Fig. 45), eggs were most concentrated in the

Middle Atlantic and southern New England subareas.

North of Chesapeake Bay they were mainly collected in

inner shelf waters. South of the Bay they were spread

across the entire shelf. As spawning declined in October and November, the areal distribution of searobin

eggs decreased, receded southward, and shifted offshore

(Fig. 46).

The unusually high mean egg abundance observed

during survey 45 in 1983 (Fig. 45) was influenced by

our sampling coverage and was probably biased upward.

Otherwise, there was no apparent change in mean egg

density over the sampling period.

Centropristis striata, black sea bass

(Figs. 48-50)

eentrapristis striata eggs occurred in January and from

April to October; they were most abundant from June

to September (Fig. 48). These eggs occurred mainly in

the Middle Atlantic subarea, but also occurred in southern New England waters to eastern Long Island during

peak spawning (Fig. 49). They extended across the shelf

in southern areas, but tended to be restricted to midshelf and the inner half of shelf waters in the northern

portion of their range.

Spawning began between Cape Hatteras and Chesapeake Bay as early as April but more commonly did not

begin until May (Fig. 50). Spawning expanded northward during June to August, occurring predominantly

in the inner half ofshelfwaters. Peak spawning occurred

in August (Fig. 48) when eggs occurred from south of

Chesapeake Bay to off Long Island and were most concentrated between Cape Hatteras and southern NewJersey. Spawning declined during September and October,

resulting in increasingly patchy egg distributions and

greatly diminished mean egg densities (Figs. 48 and 49).

Lopholatilus chamaeleonticeps, tilefish

(Figs. 51-53)

Laphalatilus chamaeleanticeps eggs were collected from

March to November and were restricted to the outer

edge of the continental shelf. The highest mean egg

densities occurred in May and June (Fig. 51).

Spawning began in March or April along the shelf

edge from east of Delaware Bay and 1 ewJersey to south

of Nantucket Shoals. At the peak of spawning in May

and June, eggs occurred from south ofChesapeake Bay

to southeastern Georges Bank. Spawning diminished in

the following months and ended by November (Fig. 52).

A downward trend in mean-egg-densities was apparent over the nine-year survey period. The four highest

values occurred from 1979 to 1983, and the lowest annual values during the last five years (Fig. 51).

Month

Pomatomus saltatrix eggs were collected from May to

August, and were most abundant inJuly (Fig. 54). They

were distributed in the Middle Atlantic and southern

New England subareas (Fig. 55).

P saltatrix spawning was highly seasonal. In some years

it began as early as May near Cape Hatteras, and was

well established by June. During June, spawning expanded rapidly northward throughout the Middle Atlantic subarea with the broadest areas of egg distribution occurring in the southern half of that subarea. Although eggs occurred across the breadth of the shelf,

greatest concentrations occurred in mid-shelf waters.

Peak spawning occurred in July when the egg distribution extended into southern ew England waters, with

the cen ter of abundance off Delaware Bay and ewJersey. Spawning continued into August but at a diminished

rate (Fig. 55). Spawning ceased by the end of August.

Cynoscion regalis eggs were collected from March to August (Fig. 57) and occurred between Cape Hatteras and

arragansett Bay, predominantly in the inner one-half

to one-third of shelf waters.

Spawning began as early as March or April in southern areas. It expanded rapidly northward in nearshore

waters, extending to ewJersey in May, to south ofLong

Island inJune, and in some years to Narragansett Bay in

July. Thereafter spawning declined; it was reduced to

between Cape Hatteras and New Jersey in August and

ceased altogether by September (Fig. 58). 40

Micropogonias undulatus, Atlantic croaker

(Figs. 60-62)

Micropogonias undulatuseggs occurred almost exclusively

in the Middle Atlantic subarea from July to November

(Fig. 60) and they tended to be concentrated in the inner half of the shelf (Fig. 61).

Spawning began in July or August in inshore waters

ofthe Middle Atlantic subarea, initially occurring south

of Chesapeake Bay and expanding rapidly northward,

as far north as Delaware Bay (Fig. 61) in some years.

Peak spawning occurred in September, largely within

this same area. Spawning declined during October and

November and ceased by December.

The pronounced peak in mean egg density in September and the 10-fold difference between means in

September and October could be biased by sampling

effort (Fig. 60). The sampling effort in September was

biased toward an area where eggs might be expected to

occur, while in October toward the area of expected nonoccurrence (Fig. 2).

Tautoga onitis eggs were collected April to September,

and were most abundant in early summer (Fig. 63). Eggs

occurred in coastal and midshelf waters, reflecting the

nearshore distribution of adults (Fig. 64).

Spawning begins as early as April in the southern portion of the Middle Atlantic subarea and by May

progresses northward into the southern New England

subarea. Peak spawning occurred in inshore waters from

south of Chesapeake Bay to Nantucket shoals in June

and July, followed by a decline during August. By September, spawning is reduced to isolated locations in

southern New England waters and ceased entirely by the

end of the month (Fig. 64).

Tautogolabrus adspersus eggs were common inshore during spring and summer. They were collected from May

to November, and were most abundant inJune and July

(Fig. 66).

Spawning began in inshore waters during May in the

Middle Atlantic and southern New England subareas and

in some years in the western Gulf of Maine near Cape

Cod, Massachusetts (Fig. 67). Peak intensity occurred

during June and July and expanded in area from south

ofChesapeake Bay to northern Gulf of Maine and on to

Georges Bank. During peak spawning, the greatest numbers of eggs were caught in shallow coastal waters and

on central Georges Bank. Spawning declined rapidly

during August, particularly in the Middle Atlantic and

southern New England subareas, but continued at lower

intensities in Georges Bank and peripheral Gulf of Maine

waters. From September to November increasingly fewer

and more isolated patches of eggs were found, and

spawning ceased by the end of November.

There was an apparent decline in egg abundance and

spawning level over the nine-year sampling period (Fig,

66). However, at peak spawning periods, particularly for

years after 1983, only partial sampling coverage was attained. In addition, the spawning area of T adspersus

extends into sounds and embayments that were not

sampled in this study.

__ Berrien & Sibunka: Distribution Patterns of Fish Eggs in the U.S. Northeast Continental Shelf Ecosystem, 1977-1987 203

Uranoscopidae, stargazers (Figs. 69-71)

Eggs identified as Uranoscopidae could include as many

as three species (Astroscopus guttatus, A. y-graecum, and

Kathetostoma albigutta). We assumed that most of these

eggs were A. guttatus whose range is reported as Cape

Hatteras, North Carolina, to Long Island, New York; A.

y-graecum and Kathetostoma albigutta reportedly occur at

Cape Hatteras and southward (Berry and Anderson,

1961) .

Uranoscopidae eggs were collected from April to October. They were found exclusively within the Middle Atlantic subarea and occurred across the entire breadth

of the shelf. Mean egg abundance was minimal in April,

peaked in July and August, and diminished to almost

nothing by the end of October (Fig. 69). Uranoscopid

eggs were never very abundant, but remained a consisten t component of the ich thyoplankton th roughou t the

study (Fig. 69).

Spawning began as early as April in the southern portion of the Middle Atlantic subarea and spread rapidly

northward during Mayas far as Delaware Bay, occurring

mostly in the inner half of shelf waters, particularly in

more northern areas. For the remainder of the spawning season (June to October), the total spawning area

remained relatively static while major concentrations of

eggs tended to shift into slightly deeper mid-shelf waters (Fig. 70).

Auxis spp., frigate and bullet mackerels

(Figs. 72-74)

Auxis spp. eggs were collected from May to September,

with highest abundances occurring during summer (Fig.

72). Most were taken south of Delaware Bay in the

Middle Atlantic subarea, with isolated occurrences in

the outer half of shelf waters in the southern ew England subarea (Fig. 73).

Spawning by Auxis spp. was highly seasonal. It began

and ended abruptly with peaks fromJune to August (Fig.

72). In some years, eggs first appeared offshore south

of Delaware Bay as early as May, but in others, not until

June orJuly. DuringJune,July, and August they generally occurred south of Delaware Bay across the breadth

of the shelf. During most years eggs were most abundant near the shelf edge. North and east of Delaware

Bay, eggs were found in isolated patches. In September

eggs occurred infrequently in isolated patches near the

shelf edge. Auxis spp. adults occur in neritic and oceanic waters, hence our survey of shelf waters sampled

just a portion of their distribution.

Sarda sarda spawned during spring and summer. Eggs

were collected from May through August with a peak in

abundance during July (Fig. 75) and occurred across

the entire breadth of the shelf (Fig. 76).

Spawning began in May in the southern portion of

the Middle Atlantic subarea, progressed northward

throughout shelfwaters to the New York Bight in June,

and extended to off Nantucket Shoals byJuly (Fig. 76).

o spawning occurred north and east of Nantucket

shoals. The largest concentration of eggs and greatest

intensity ofspawning occurred during July off NewJersey and Long Island. During August, spawning activity

diminished to isolated locations and ceased by the end

of the month (Fig. 76).

The mean egg density for survey 17 in 1979 indicated

that large numbers of Atlantic bonito spawned. In subsequent years, maximum mean egg densities ranged

from 4 to 37% of the 1979 level. The low values for 1985

could indicate a decrease in spawning activity as there

was no bias in sampling during 1985 (Figs. 75 and 77).

Sromber srombrus; mean-egg-densily graphs by month

(top) and by survey (bollom) for the total MARMAP

area. (*Samples from the last two surveys in 1977 and

the first four surveys in 1978 were not analyzed for S.

scomhrus eggs.)

Scomber scombrus eggs were collected from April to August. They were highly seasonal in occurrence, exhibiting short periods of increasing, peak, and decreasing

abundance, and occurred across the en tire width of the

shelf (Figs. 78 and 79),

S. scombrus eggs were one of the most abundant species taken, second only to Anchoa mitchilli in total eggs

caught. This is a highly migratory species, and spawns

as it moves (Sette, 1943). Areas of high egg ahundance,

indicating concentrations of spawners, shifted northward and eastward as the season progressed. In April

eggs occurred over most of the Middle Atlantic subarea

and into southern ew England waters. Dramatically

higher egg densities in May and June reflected peak

spawning that was most intense in southern New England and western Gulf of Maine. Spawning rapidly declined inJuly, ending in August at isolated locations in

southern New England, Georges Bank, and Gulf of

Maine.

A decline in egg abundance and spawning levels occurred between 1977 and 1987 (Fig. 78). either the

two highest survey values shown (1977 and 1979), nor

the lower levels in more recent years (except perhaps

1985) could be accounted for by a bias in sampling coverage (Fig. 80).

Peprilus triacanthus, butterfish (Figs. 81-83)

Peprilus triacanthus eggs were collected from April to

September, indicating spring and summer spawning

(Fig. 81). They were collected throughout the survey

area, with greatest concentrations found in the Middle

Atlantic and southern New England subareas.

Spawning began as early as April at isolated locations,

primarily along the continental slope where spring water temperatures were higher than those in adjacent

shelfwaters. As the season advanced and water temperatures rose, spawning advanced shoreward in a south to

north progression extending onto Georges Bank and

into the Gulf of Maine (Fig. 82). Peak spawning months

were June and July, followed by decreased spawning in

August and September (Fig. 81).

Spawning intensity decreased over the nine-year study

period (Fig. 81). For the first two years (1979 and 1980),

high mean egg densities exceeded 80/10 m2. Peak mean

densities for subsequent years were lower (with the exception of 1981 and 1986), ranging from 7/10 m2 to

41/10 m2. High densities during 1981 and 1986 (surveys 30, 31, 32, and 68) resulted in part from a lack of

adequate sampling effort in areas of expected low abundance, thus biasing results of these surveys upward (Figs.

81 and 83).

Eggs assigned to this two-genus category probahly consist of two species, the deeper water Citharichthys arrtifrons,

and the relatively shallow water Etropus mzcrostomus, The

bi-modality in monthly egg distributions fromJune,July,

and August, and to a lesser extent May, is most likely

due to the two-species composition uf the data,

Eggs of Citharichthys/Etropus spp, were collected during 11 months of the year; absent only during December. They were most abundant in summer (Fig. 84),

Spawning began near Cape Hatteras in April and increased rapidly during May. Spawning occurred throughout the Middle Atlantic and southern ew England suhareas and the southern portion of Georges Bank.

Through June, July, and August eggs occurred in thf'

same areas but in greater numbers than in May. Spawning peaked inJuly and August and, by August, expanded

to include most of Georges Bank. Thereafter, spawn ing

decreased in intensity through September and Oetobf'r,

and by November decreased dramatically in areal f'Xtent (Fig. 85). Spawning was minimal from Januarv to

March. The apparent lack of eggs from Decemher

samples is most likely due to lack ofsampling in all years

in the area from Chesapeake Bay southward (Fig. 2).

There was no apparent change in the overall ahundance

of Citharichthys/Ftropus eggs over the sampling period

(Fig. 84).

Two distinct spawnings of PamlichthJs dentatus were observed. Intense spawning occurred in autumn and winter of every year over much of the Middle Atlantic and

southern ew England subareas. A lesser spawning occurred during spring in the southern half of Middle

Atlan tic waters (Figs. 87 and 88).

The major spawning of P dentatus began in September in inshore waters of the Middle Atlantic and southern New England subareas. Peak spawning occu:-red in

October and egg distribution broadened to include

much of Georges Bank. In the Middle Atlantic and southern New England subareas, spawning spread into deeper

mid-shelf waters. Spawning in deeper waters continued

into November when eggs were found across the entire

breadth of the shelf. Major egg concentrations occurred

in southern New England and northern Middle Atlantic subareas in mid- and outer-shelf waters. This trend

for spawning to occur in increasingly deeper waters during autumn parallels the offshore migration of adults

during that season (Smith and Daiber, 1977). In November, spawning on Georges Bank was greatly diminished. Spawning in December andJanuary was reduced

to isolated locations in outer shelf waters of the Middle

Atlantic and southern New England subareas (Fig. 88).

The lesser of the two seasonal spawning events was observed in the southern portion of the Middle Atlantic

subarea during April and May (Fig. 89) during 1979,

1986, and 1987.

Paralichthys oblangus, fourspot flounder

(Figs. 90-92)

Paralichthys oblongus eggs were collected from April to

November (Fig. 90) and were abundant over most of

the eight months, occurring mostly in Middle Atlantic,

southern New England, and the southern half of

Georges Bank waters and only occasionally in the Gulf

of Maine. They occurred over the entire breadth of the

shelf (Fig. 91).

Spawning began offshore, usually in May but often as

early as April, then spread onto the shelf (see Surveys

16, 50, and 76; Fig. 92). Spawning generally began in

the Middle Atlantic subarea and by May was widespread

throughout Middle Atlantic, southern New England, and

southern Georges Bank subareas. Peak spawning was

observed in July when eggs occurred in an almost continuous distribution throughout shelf waters between

Cape Hatteras and central or eastern Georges Bank.

Spawning remained widespread through August and

September, although at decreasing intensity. It greatly

diminished in area through October and November,

ceasing altogether by December.

Scophthalmus aquosus, windowpane

(Figs. 93-95)

Scophthalmus aquosus eggs were collected from February

to November and were abundant from May to October

(Fig. 93). They were mostly found in nearshore shelf

waters and in the cen tral, shallower portion of Georges

Bank (Fig, 94).

Spawning began in February or March in inner shelf

waters, usually between Cape Hatteras and New Jersey,

although in some years as far north as Long Island, New

York. The area expanded in April into deeper waters,

and onto Georges Bank in some years, Throughout peak

spawning months of May through October, eggs were

found over broad areas of the Middle Atlantic, southern New England, and Georges Bank subareas, and occasionally into the Gulf of Maine. During this period of

sustained high egg abundance the major concentrations

of eggs remained in shallower areas. Increased numbers

of eggs also occurred offshore, as far as the shelf edge

during June to September (Fig. 94). Throughout the

spawning season there was a regular progression in the

location of areas of high mean egg density (>100/10 m2),

shifting north and east from April to August, then west

and south as spawning waned, from August to November (Fig, 94),

The absence of S. aquosuseggs in December could be

due to the lack of sampling in the southern half of the

Middle Atlantic subarea (Fig. 2). With the exception of

1982 and 1987 there appeared to be an upward trend in

maximum mean egg density from 1979 to 1987 (Fig. 93).

Glyptocephalus cynoglossus eggs were collected from February to October. A seasonal cycle in egg abundance

was observed with a peak inJune (Fig. 96). Eggs occurred

across the en tire breadth of shelf waters in the Middle

Atlantic, southern New England, and Georges Bank subareas, but in the Gulf of Maine they usually were only in

the nearshore or shoal areas (Fig. 97).

Spawning began in the south, expanded northward

through spring and summer, and subsequently receded

from south to north. Eggs first occurred in February or

March in the vicinity of Chesapeake Bay, expanded

northward into southern New England in April, and onto

Georges Bank and in the Gulf of Maine in May. During

peak spawning in June, eggs occurred at scattered locations in the Middle Atlantic and in the western portion

of the southern New England subarea, were widespread

in shelf waters south of Nantucket Shoals and on southcentral Georges Bank, and were heavily concentrated

in western, northern, and eastern Gulf of Maine. From

July through October, egg abundance declined and eggs

were centered at the northern and western GulfofMaine

and western Georges Bank.

The absence of G. cynoglossus eggs on the Scotian Shelf

during July and August could be attributed to a lack of

sampling (Fig. 97). Similarly, the decrease in mean egg

density in July, as compared to May, June, and August

(Fig. 96), was probably influenced by partial sampling

coverage in the Gulf of Maine duringJuly.

Hippoglossoides platessoides, American plaice

(Figs. 99-101)

Although eggs of Hippoglossoides plalessoides were collected year-round, there was a strong seasonal cycle in

egg abundance, with fewest eggs occurring in autumn

and early winter, and peak densities during spring and

early summer (Fig. 99). They were most abundant in

shallower portions of the Gulf of Maine and Georges

Bank (Fig. 100).

Spawning was minimal from September to January,

followed by a rapid increase from February to April. Egg

densities in March in the Gulf of Maine were probably

underestimated due to a lack ofsampling (Fig. 2). During April and May the distribution of H. plalessoides eggs

was most extensive and mean densities were highest

(Figs. 99 and 100). Thereafter (from June to September) spawning diminished and receded to isolated locations in western and northern Gulf of Maine.

A downward trend in survey mean-egg-density was

observed (Fig. 99). But the highest survey mean-eggdensity (in 1979) probably overe~timatedthe true mean

density because sampling coverage during that survey

was lacking in the Middle Atlantic subarea, an area where

eggs were not expected to occur (survey 15, Fig. 101).

Figure 101 (continued)
298 NOAA Technical Report 145 _

Pleuranectesferrugineus, yellowtail flounder

(Figs. 102-104)

Pleuronectes ferrugineus eggs were collected from February to September, with peak abundances from April to

June (Fig. 102). During months of high abundance, eggs

were widespread across most of the shelf, with concentrations in the inner shelf. Areas of high egg density

occurred from New York Bight to eastern Georges Bank

and in western and Scotian Shelf portions of the Gulf of

Maine.

Spawning began in February or March, occurring first

in the northern halfofthe Middle Atlantic subarea, then

extending rapidly into southern New England and

Georges Bank (Fig. 103). In April and May spawning

increased in intensity in the same areas plus the Gulf of

Maine. While the overall level of spawning remained

high inJune, spawning intensity and the areal distribution of eggs receded in Middle Atlan tic waters. Thereafter spawning diminished rapidly in July and ended in

August or September. The mean egg density forJuly (Fig.

102) was probably underestimated due to a lack ofsampling on the Scotian Shelf (Fig. 2).

A downward trend in spawning level was observed

(Fig. 102), with peak egg abundances lower during the

last three years (1985-87).

Acknowledgments

We extend our thanks to the many people who worked

on the MARMAP program over several years. We than k

the vessel crews of the RjVAlbatross IVand RjVDelaware

JJ; the many sea-going technicians and biologists who

collected plankton samples and data; and the laboratory technicians at Sandy Hook and at the Sorting Center in Szczecin, Poland, who helped sort, identify, count,

and stage slightly more than two million fish eggs. We

also thank Wallace Smith and Kenneth Sherman who

supported this effort over the years,Jay O'Reilly for use

of his Fortran program which enhanced the contoured

distribution maps, two anonymous reviewers, and Dave

Packer whose comments helped make this paper readable. Completion ofthis document was supported in part

by funds from the NOAA Office of Global Programs.
