NOAA TECHNICAL REPORTS NMFS

The major re,ponsibilities of the National Marine Fisheries Service (NMFS) are to monitor and assess the abundance

and geographic distribution of fishery resources, to understand and predict fluctuations in the quantity and distribution of

these resources, and to establish levels for optimum use ofthe resources. NMFS is also charged with the development and implementation of policies for managing national fishing grounds, development and enforcement of domestic fisheries regulations, surveillance of foreign fishing off United States coastal waters, and the development and enforcement ofinternational

fishery agreements and policies. NMFS also assists the fishing industry through marketing service and economic analysis

programs, and mortgage insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics on various

phases of the industry.

The NOAA Technical Report NMFS series was established in 1983 to replace two subcategories of the Technical

Reports series: "Special Scientific Report-Fisheries" and "Circular." The series contains the following types of reports:

Scientific investigations that document long-term continuing programs of NMFS, intensive scientific reports on studies of

restricted scope, papers on applied fishery problems, technical reports of general interest intended to aid conservation and

management, reports that review in considerable detail and at a high technical level certain broad areas of research, and

technical papers originating in economics studies and from management investigations.

Copies of NOAA Technical Report NMFS are available free in limited numbers to governmental agencies, both Federal

and State. They are also available in exchange for other scientific and technical publications in the marine sciences. Individual copies may be obtained from: Publications Services Branch (EIAI 13), National Environmental Satellite, Data, and In·

Ichthyoplankton Survey of the Estuarine and

Inshore Waters of the Florida Everglades,

May 1971 to February 1972

L. ALAN OLLINS and JOHN H. FINUCANE!

ABSTRACT

Quarterly ichthyoplankton sampling was conducted at 16 estuarine and 24 inshore stalions along the Florida

Everglades from May 1971 to February 1972. The area is one of the most pristine along lhe Florida coast. The

survey provided the first comprehensive information on seasonal occurrence, abundance (under 10 m' of surface

area), and distribution of fish eggs and larvae in this area. A total of 209,462 fish eggs and 78,865 larvae was

collected. Eggs were identified only as fish eggs, but among the larvae, 37 families, 47 genera, and 37 species

were identified. Abundance of eggs and larvae, and diversity of larvae, were greatest in the inshore zone. The 10

most abundant fish families which together made up 90.7% of all larvae from the study area were, in descending

order of abundance: Clupeidae, Engraulidae, Gobiidae, Sciaenidae, Carangidae, Pomadasyidae, Cynoglossidae,

Gerreidae, Triglidae, and Soleidae. Clupeidae, Engraulidae, and Gobiidae made up 59.9% of all larvae. The

inshore zone (to a depth of about 10 m) was a spawning ground and nursery for many fIShes important to fisheries.

The catch ofsmalllarvae (<>3.5 mm SL) indicated that most fishes identified from the 10 most abundant families

spawned throughout the inshore zone at depths of <> 10 m, but Orthopristis chrysoptera, Gerreidae, and Prionotus

spp. spawned at depths of;" 10 m, with offshore to inshore (eastward) larval transport. Salinity was one ofseveral

environmental factors that prohably limited the numbers of eggs and larvae in the estuarine zone. Abundance of

eggs and larvae at inshore stations was usually as great as, and sometimes greater than, the abundance of eggs

and larvae at offshore stations (due west of the Everglades).

INTRODUCTION

The National Marine Fisheries Service (NMFS) conducted

studies of the Everglades National Park during 1971 and 1972

as part of a multiagency program to assess various aspects of

the south Florida ecosystem. The objective of NMFS wa5 to

determine the distribution and abundance of eggs, larvae, and

juveniles of fishes within the estuarine and inshore waters of

the park. Lindall et al. (1973) reported on juvenile fishes in the

study area. This paper reports the distribution and abundance

of fish eggs and larvae.

Everglades National Park is one of the most pristine and

biologically productive coastal regions of the Gulf of Mexico.

Federal protection has left the park essentially unaltered by

dredging, filling, bulkheading, and pollution. The region is

subtropical in climate, fauna, and flora. The park includes a

complex series of ecosystems including some of the last remaining wilderness area in south Florida. Approximately 59,896 ha

(148,000 acres) are estuarine (McNulty et al. 1972) and are

characterized by mangrove-covered islands interspaced by open

water. Mangroves are active land builders and protect the

lowlands from erosion during storms. Mangrove leaves are a

major source of organic detritus used as food by some invertebrates and fishes (Odum 1971). The mangrove zone forms the

transition between the estuary and upland. Tides are semidiurnal

or diurnal and range from 0.2 to 1.4 m (U.S. Coast and Geodetic

Survey 1970). Variation of the freshwater flow through the

park is sometimes great. During periodic floods, the "river of

fresh-water discharge through the Everglades becomes an

important factor in the inshore circulation" which is normally a

wind-dependent surface current moving west to southwesterly

where depths are> 10 m (Jones et al. 1973).

The estuary and adjacent inshore zone provide spawning

and nursery grounds for many species of fish and shellfish.

Studies of adult and juvenile fish have shown that these areas

possess an abundant and diverse fish fauna. Tabb and Manning

(1961) and Roessler (1970) reported 138 species in 55 families

and 103 species in 49 families, respectively, in the south

Everglades estuary. In 1972,96 species in 41 families of fishes

were collected in a northern Everglades area (U .S. Environmental Protection Agency 1973). Lindall et al. (1973) took

juveniles representing 114 species in 44 families from estuarine

and inshore waters within the area covered by our study. They

found that the estuary was more important than the inshore

zone of the Gulf of Mexico as a nursery area.

Little is known about the ichthyoplankton of the Everglades

region. The only larval fish study in this area was confined to

the family Sciaenidae (Jannke 1971). Houde and Chitty (1976),

Houde et al. (1976, 1979), and Leak (1977) reported information on fish eggs and larvae from the continental shelf area

adjacent to our study area. Nakamura et al. (1980) listed life

stages of recreationally important marine fishes that have been

collected from estuarine waters between Cape Romano and

Florida Bay. An ichthyoplankton survey to assess spawning

areas for sport fishes in the park was recently begun (Leak2).

STATIONS AND METHODS

Three aquatic zones are recognized in this report. These are

the estuarine, inshore, and offshore zones among which only

the estuarine and inshore zones were sampled. The estuarine

zone was defined as the semienclosed body of water where

freshwater and saltwater mix. The boundary between the

estuarine and inshore zones was an imaginary line connecting

points of land marking entrances to embayments. The inshore

zone was the aquatic zone adjacent to and seaward of the

estuarine zone extending 39 km offshore. The offshore zone is

the area beyond 39 km offshore which was sampled by Houde

et al. (1979) during their ]971-74 survey.

Forty stations were sampled quarterly in our study. Sixteen

estuarine stations were located in bays and at the mouths of

major rivers from Caxambas Pass south to Buttonwood Canal

near Flamingo (Fig. 1). Twenty-four inshore stations were

located along eight east-west transects evenly spaced between

Cape Romano and Cape Sable. Each of these transects was 9

km apart and consisted of three stations, each 19 km apart. A

description of most of our estuarine stations, and all inshore

stations, was given by Lindall et al. (]973).

At each estuarine and inshore station three hydrographic

parameters were measured. Salinity and temperature were

measured with an induction salinometer. Dissolved oxygen

was measured by a modified Winkler method (Strickland and

Parsons 1968).

Because estuarine and inshore stations had substantially

different water depths, ichthyoplankton sampling methods

differed in the two zones. All estuarine stations had water

depths of2.5 m or less (Table 1) and were sampled with a 0.5 m

plankton net (505 IJ..m mesh), which was towed on the surface

at all 16 stations from off the side of a 4.9 m outboard motorboat. Most inshore stations were deeper (Table 1) and were

sampled with aIm net (505 IJ..m mesh) from the RV Bellows,

a 19.8 m, diesel-powered boat. Nine of the inshore stations had

water depths of 2.5 m or less and were sampled with surface

tows. The middle stations on Transects II to VIII had an average depth of 5.4 m; those seven stations, and the eight most

seaward stations on each of the eight transects, were sampled

with step-oblique tows. Step-oblique tows began near the

bottom and covered approximately 80% of the water column.

Estimates of volumes of filtered water and of egg and larval

abundances were made from all tows. A flowmeter was mounted

approximately 20% off-center in the mouth of the nets. The

nets were pulled at 2-3 kn for 10 min in the estuarine zone and

for 5 min in the inshore zone. From the number of revolutions

of the meter during tows, the volume of filtered water was

calculated (Tables 2 to 5). The tables also show abundance

NxDxlO according to the formula A = V ,where A = abundance

under 10 m2 of sea surface, N = number of collected eggs or

larvae, D = depth (station or tow), and V = volume offiltered

water. To estimate abundance from surface tows, we assumed

that eggs and larvae were uniformly distributed from surface

to bottom at the stations where depth was ,,;;2.5 m. Thus, to

calculate abundance, the station depth was used for surface

tows, and the tow depth was used for oblique tows.

Both day and night samplings were conducted. All estuarine

samples were taken during daylight hours due to navigational

problems. During the first 3 mo, stations from the inshore area

2

were also sampled by daylight in order initially to ensure that

the large vessel could safely navigate the shallowest stations;

all other inshore cruises were made at night. No day or night

sampling was done for comparative purposes. The average

duration of seasonal cruises was 6 d for the two zones.

All plankton samples were preserved in a 5% Formalinseawater solution buffered with marble chips. All fish eggs and

larvae were removed from the samples and counted. Settled

plankton volumes were estimated to the nearest milliliter after

removal of tenophores, seagrasses, algal clumps, mangrove

detritus, and debris (Tables 2 to 5). Volumes of neither the

latter particles nor of the fish eggs and larvae were measured.

Fish < 10 mm were measured to the nearest 0.1 mm standard

length (SL) with the aid of an ocular micrometer. Specimens

> 10 mm were measured to the nearest millimeter SL with a

ruler.

Eggs were identified only as fish eggs, but larvae and juveniles

were identified to the lowest possible taxon. Meristics, morphology, and pigmentation were used to identify fishes. Many

larvae <5 mm were listed as unknown or were identified only

to family, although identification was sometimes possible when

good series were found. We used the serial or dynamic method

of tracing certain characters back from juvenile to larval

specimens (Moser and Ahlstrom 1970). Most identifications

were verified by comparisons with specimens in our reference

collection from the Tampa Bay area and with the collections of

the NMFS Southeast Fisheries Center Laboratory at Miami,

Fla., and the Florida Department of Natural Resources Marine

Laboratory at St. Petersburg. The sciaenid larvae were compared with illustrations of previously identified specimens from

the same general area (Jannke 1971). The nomenclature of

Robins et al. (1980) was used.

The distribution and abundance of fish eggs and larvae

indicated productivity (Houde and Chitty 1976) and spawning

at estuarine and inshore stations. In some instances, specific

identification of small (,,;;3.5 mm) larvae permitted inferences

on spawning of a particular fish.

Our catches were compared spatially and temporally with

those from the offshore zone made by Houde et al. (1976,

1979). For some comparisons we used data from the offshore

stations that were sampled due west of the Everglades during

the same months and year(s) that we sampled in the estuarine

and inshore zones. For other comparisons we used the summarized data from the entire offshore zone that was sampled

seasonally from 1971 to 1974.

RESULTS

Hydrography

As expected, salinity values were more stable in the inshore

zone than in the estuarine zone (Table 6). Inshore salinities

ranged from 26.2 to 38.4 ppt, while estuarine salinities ranged

from 1.8 to 41.2 ppt. Seasonally, inshore salinities never varied

more than 9.1 ppt, while estuarine values varied by at least

24.6 ppt. Hypersaline conditions were noted during May 1971

in nearly all estuarine and inshore waters and were the result

of a severe drought throughout most of south Florida. In Table

7 we list ranges of salinity, as well as of temperature, within

which dominant larval fishes were collected.

Water temperatures were about the same for the estuarine

and inshore zones (Table 6). The 16 estuarine stations had a
range of 18.6° to 31SC. The 24 inshore stations had a range of

19S to 30.0°C.

Most dissolved oxygen values were near saturation (Table

6). Only 3 of the 229 water samples had values <3.0 mUI.

General Distribution and Abundance of

Ichthyoplankton

During this survey, 209,462 eggs and 78,865 larvae were

collected from all tows. Numbers of eggs and larvae taken at

all stations for each of the four quarters are given in Tables 2 to

5. Seasonal abundances are illustrated for each of the 40 stations

in Figures 2 and 3.

May. - Egg abundances indicated that spawning during

May 1971 was heaviest near the center of the inshore zone

(Fig. 2, Table 2). The intermediate station on Transects III and

IV had high egg abundances: 4,441 and 1,334 eggs under 10

m2

, respectively. In May 1971, total egg abundances from stations

in the inshore and offshore zones (Houde et al. 1976) indicated

that the waters <30 m deep west of the Everglades were a

major spawning area for species with pelagic eggs. Eggs in the

estuarine zone occurred mainly at Stations 7, 8, and 15. Most

of the estuarine stations had fewer eggs under 10 m2 than the

inshore stations.

The greatest abundance of larval fish in the inshore and

offshore zones was found at our Station 11-3 during this month

(Fig. 3, Table 2, and Houde et al. 1976). In general, however,

the offshore stations sampled by Houde et al. (1976) had a

greater average larval abundance than did our inshore stations.

August. - Most inshore and estuarine spawning in August

1971 seemed to have occurred in the area of our two mostseaward stations (Fig. 2). Four inshore stations and one estuarine

station had egg abundances> 1,000 under 10 m2 . Only 1ofthe 26

offshore stations due west of the Everglades had as great an egg

abundance (Houde et al. 1976). Stations 8,14, and 15 were the

estuarine locations where fish eggs were most abundant.

Our most-seaward stations on Transects I, II, III, and IV had

the most fish larvae (>1,000 under 10 m2

). Only one offshore

station had as high a larval abundance. Abundance of fish

larvae ranged from 0 to 3 under 10 m2 at the 16 estuarine

stations during August (Fig. 3, Table 3).

November. - The third-quarter egg data (Table 4, Fig. 2)

indicated that spawning was considerably less than in the

previous two quarters. Values exceeding 100 eggs under 10 m2

were found only at seven inshore stations. Samples near the

Everglades were not collected by Houde et al. (1976) in

November 1971. In the estuarine zone, eggs were most abundant

at Stations 1, 14, and 15.

Larvae were in low abundance (0 to 158 under 10 m2)

compared with the previous two quarters (Fig. 3). The highest

larval numbers under 10 m2 were found at either Station 2 or

Station 3 on all transects.

February. - In February 1972, egg abundances were high,

especially in our northern, inshore zone (Table 5, Fig. 2). Five

inshore stations had>1,000 eggs under 10 m2, while only one of

seven offshore stations equaled this abundance (Houde et al.

1976). Stations 1 and 15 had the most eggs in the estuarine

zone, where the abundance ranged from 0 to 193 under 10 m2 .

3

Larval fish abundances in both the estuarine and inshore

zones for February were about the same as for November.

Values were from 0 to 186 under 10 m2 in February and from 0

to 158 in November. The data from Houde et al. (1976) from

farther west on the continental shelf indicated greater abundances of larvae, ranging from 10 to 1,131 under 10 m2 . Our

southern transects had the highest inshore abundance of larvae,

while Station 15 had the highest estuarine abundance (Table 5).

Ten Most Abundant Families of Larvae

Thirty-seven families, 47 genera, and 37 species of larvae

were identified in our survey. Ten families constituted 90.7%

(three families constituted 59.9%) of all larvae (Table 8). Of

the 10 most abundant families for the entire four quarters of

sampling, only the engraulids, gobiids, sciaenids, and triglids

each made up at least 1.5% of the total catch in all sampling

periods. Summaries of occurrence of the 10 most abundant

families in the estuarine and inshore zones are given in Tables

9 and 10. Results for the 10 most abundant families in decreasing

order of abundance follow.

Clupeidae. - The clupeids in the inshore zone were most

abundant at depths of 5.5 to 12.0 m in August, while very few

fish were ever collected in the estuarine zone (Fig. 4). Most

clupeids in our catch were too small to identify to genus, although

we recorded 4 genera and 3 species: Opisthonema oglinum,

Harengula jaguana, Sardinella brasiliensis, and Brevoortia sp.

The majority of our smallest (<:;3.5 mm) larvae were collected

during May and August at the most seaward stations (Tables

11-14). Houde et al. (1979) reported that most of their clupeid

larvae were collected from waters <30 m deep during spring

and summer months. The offshore catch consisted of 5 genera

and 4 species, including all of the species that we identified,

except S. brasiliensis. They also recorded S. anchovia and

Etrumeus teres.

Opisthonema oglinum was the most abundant clupeid; most

were found at inshore stations of 5.5 to 8.0 m depth during

August (Fig. 5). This was the second most common clupeid in

the offshore zone, where the majority was taken at the most

landward stations (Houde et al. 1979). This species seemed to

spawn offshore during spring and summer in waters <30 m

deep.

Harengula jaguana was most abundant during May and

August at inshore stations from 5.5 to 9.0 m deep (Fig. 6).

Most offshore H. jaguana were collected atstations <30 m deep

(Houde et al. 1979).

Sardinella spp. were usually found during August and February at the same stations and depths where most O. oglinum

and H. jaguana were collected (Fig. 7). Although we identified

S. brasiliensis, nearly all of our Sardinella could be identified

only to genus. Most S. anchovia in the offshore zone were

collected during late summer in waters <50 m deep (Houde et

al. 1979).

Brevoortia sp. was most abundant in February at inshore

stations of 1.5 to 2.5 m depth (Fig. 8). This was the only

clupeid identified to genus in the estuarine zone (Table 10).

Twice as many Brevoortia were collected in the inshore zone

than in the offshore zone; most larvae in waters <30 m deep
were collected during fall and winter cruises (Houde et al.

1979).

. Engraulidae. - Anchovies were most abundant during

August at inshore stations of 8.0 to 12.0 m and during May at

estuarine stations (Fig. lJ). Although we could not positively

identify anchovies to genus, most of our specimens were probably Anchoa hepsetus or A. mitchilli. These two species were

found to be abundant in the sampling area by Lindall et a1.

(1973). Anchovy larvae ,,;;3.5 mm were collected during every

sampling period in both zones with the exception of November

in the estuarine zone (Tables 11-18). Most of these small larvae

occurred during August and May in the inshore and estuarine

zones, respectively. Offshore, most engraulid larvae were caught

at stations <50 m deep during spring and summer. No genera

or species were identified by Houde et a1. (1979).

Gobiidae. - Gobies were most abundant in the inshore zone

during August at depths of 8.0 to 12.0 m and in th~ estuarine

zone during May and February (Fig. 10). We identified three

genera and no species. Larval gobies ,,;;3.5 mm occurred during

every sampling period (Tables 11-18). These small larvae were

usually collected during August and May in the inshore and

estuarine zones, respectively. In the offshore zone, nost gobies

were caught in stations <50 m deep during the spiing and summer (Houde et a1. 1979). The offshore gobies were not identified to genus or species nor were their abundances given by

station.

The dominant goby was Microgobius spp., which was most

abundant at inshore stations during August and at estuarine

stations during February (Fig. 11). Most of the smallest Microgobius also occurred during August inshore, while small larvae

mainly occurred during May in the estuarine zone (Tables 11-18).

Gobiosoma spp. were also most abundant during August,

but these were mainly found at two inshore stations that were

8.0 m deep (Fig. 12). The smallest Gobiosoma larvae were

among those caught inshore in August, while no Gobiosoma

larvae ,,;;3.5 mm were collected in the estuarine zone.

Low abundances of the third goby genus, Gobionellus, were

found only at two inshore stations (Tables 11, 12).

Sciaenidae. - Larval sciaenids were most abundant during

August at inshore stations 8.0 to 12.0 m deep and during

February at estuarine stations (Fig. 13). Five genera and four

species (Bairdiella chrysura, Cynoscion nebulosus, Menticirrhus

spp., Pogonias cromis, and Sciaenops ocellatus) were identified (Tables 9, 10). Small (~3.5 mm) sciaenid larvae usually

occurred during August inshore; very few were found in the

estuarine zone. Sciaenid larvae in the offshore zone were most

abundant at stations <10 m deep during spring and summer

(Houde et a1. 1979). The sciaenids listed above, with the

exception of S. ocellatus, were identified from the offshore

zone. Cynoscion arenarius, C. nothus, M. saxatilis, Leiostomus

xanthurus, and Micropogonias undulatus were also recorded in

the offshore zone.

Most B. chrysura were caught during August at inshore stations

that were 4.0 to 12.0 m deep and during February at estuarine

stations (Fig. 14). Many of the small larvae were found inshore

during August, although these larvae were found in both zones

in all sampling periods with the exception of the estuarine

zone in November (Tables 11-18). Most of the smallest sciaenid

larvae found in the estuarine zone were B. chrysura. Larval

4

B. chrysura were usually taken during June at offshore stations

<10 m deep (Houde et a1. 1979).

Cynoscion nebulosus was mostly found during May at some

inshore and estuarine stations 1.0 to 6.0 m deep (Fig. 15).

Larvae ~3.5 mm were found during all four sampling periods

inshore, but were found only during May in the estuarine zone

(Tables 11-18). Offshore collections of C. nebulosus were usually

made in the spring at depths <10 m (Houde et a1. 1979).

Cynoscion spp. were about equally abundant in August,

November, and February at inshore stations of 2.0 to 12.0 m

depth, while no larvae were found in the estuarine zone (Fig.

16). Most Cynoscion spp. were probably C. arenarius, but C.

nothus and C. regalis have also been reported from south Florida,

so a definite species identification of our larvae was not possible

(Stender 1980). Many larvae <3.5 mm were found inshore

during each sampling period. Houde et a1. (1979) recorded

most C. arenarius in the winter, spring, and summer at depths

<20 m. They recorded only one C. nothus at a 25 m depth.

Menticirrhus spp. were most abundant at some inshore stations

4.0 to 12.0 m deep during August and were almost nonexistent

in the estuarine zone (Fig. 17). Many of the smallest larvae

were found inshore in May, August, and November and lesser

numbers occurred inshore in February (Tables 11-18). February

was the only month in which such a small larva was found in

the estuarine zone. Offshore, Menticirrhus (saxatilis and sp.)

were usually collected during the winter, spring, and summer

at stations <20 m deep (Houde et a1. 1979).

Pogonias cromis was most abundant during November in

the inshore zone at two stations that were 5.5 to 8.0 m deep;

only a few of the fish occurred in the estuarine zone, all during

February (Fig. 18). Inshore larvae ~3.5 mm were mostly fou,nd

during November, but a few were also found in May and

February, while no such small larvae were found in the estuarine

zone (Tables 11-18). Only two P. cromis larvae were collected

offshore in shallow water during a spring cruise by Houde et

al. (1979).

Sciaenops ocellatus was collected only during August and

November at three inshore stations that were 4.0 to 6.0 m deep

(Tables 1, 12, 13). All of the larvae ,,;;3.5 mm were collected

during August (Tables 12, 13).

Two sciaenids that were collected only offshore (M. undulatus

and L. xanthurus) were rarely collected west of the Everglades

by Houde et al. (1979). They caught only one specimen of

each of these sciaenids near our inshore stations.

Carangidae. - Larval jacks mostly occurred at some inshore

stations of 4.0 to 12.0 m depth during August and were far less

abundant in the estuarine zone (Fig. 19). Only Chloroscombrus

chrysurus and Oligoplites saurus were identified. Many larvae

";;3.5 mm were found inshore during both May and August

and fewer such larvae were found in the estuarine zone in May

only (Tables 11-18). Offshore carangids had greatest abundances

at stations <35 m deep during spring and summer (Leak 1977).

Many larvae of the latter two species were collected at offshore

stations closest to the Everglades, while 10 other species of

jacks were found in waters >35 m deep.

Chloroscombrus chrysurus was most abundant at inshore

stations of 8.0 to 12.0 m depth during August while no larvae

were found in the estuarine zone (Fig. 20). Many small larvae

of this species were collected inshore during both May and

August (Tables 11, 12). Most offshore C. chrysurus were
collected during spring and summer in water <35 m deep

(Leak 1977).

Oligoplites saurus larvae were found in greatest abundance

during May at inshore stations of 8.0 m depth and were also

found at most estuarine stations of much shallower depth

(Fig. 21). Larvae ~3.5 mm were more abundant in May than

August in both zones; such larvae occurred in the estuarine

zone during May only (Tables 11-18). Offshore abundance of

O. saurus was greatest in waters <20 m deep during spring

and summer (Leak 1977).

Pomadasyidae. - The majority of the pomadasyids were

Orthopristis chrysoptera, which had greatest abundance in both

zones in February; most pigfish larvae were found at depths of

5.5 to 12.0 m inshore (Fig. 22). The smallest larvae were found

at our most seaward stations during all sampling periods (Tables

11-14). Only two larvae ~3.5 mm were found during May and

February in the estuarine zone (Tables 15-18). Offshore, O.

chrysoptera was usually caught in winter and spring at stations

<20 m deep (Houde et al. 1979).

Cynoglossidae. - Greatest tonguefish abundance was found

at inshore stations 8.0 to 12.0 m deep during August and no

larvae occurred in the estuarine zone (Fig. 23). Only Symphurus

spp. was identified but most of these larvae were probably

S. plagiusa. Most small (~3.5 mm) larvae occurred during

May and August (Tables 11-14). Offshore, Symphurus spp.

were mostly obtained at stations <50 m deep in the spring

and summer (Houde et al. 1979).

Gerreidae. - Gerreids were most abundant at inshore

stations 8.0 to 12.0 m deep during May and were found only

during May in the estuarine zone (Fig. 24). Most of the gerreids

that we collected were probably Eucinostomus argenteus or

E. gula. Smallest (~3.5 mm) larvae usually occurred at the most

seaward stations in May and August and were not found during

any other months (Tables 11-14). Such larvae in the estuarine

zone were found during May only (Tables 15-18). Offshore

larvae were most abundant at stations <50 m deep in the spring

and summer and were not identified to genus or species

(Houde et al. 1979).

Triglidae. - Prionotus spp. were most abundant at inshore

stations with depths of 8.0 to 12.0 m during August; only two

larvae were caught at estuarine stations, both during February

(Fig. 25). The smallest larvae occurred at the most seaward

stations during all four sampling periods (Tables 11-14). Offshore

triglids were usually caught at depths of <50 m during all

seasons and were not identified to genus (Houde et al. 1979).

Soleidae. - Most sole larvae were Achirus lineatus, which

had its greatest abundance at inshore stations 4.0 to 9.0 m

deep during August; only a few larvae were present in the

estuarine zone during each quarter (Fig. 26). Larvae ~3.5 mm

were common in the inshore zone in May and August, while

such larvae were uncommon there in November and February

(Tables 11-14). A few of these small larvae occurred in the

estuarine zone in May, August, and February (Tables 15-18).

Offshore, A. lineatus was most abundant in depths of <15 m

during the spring and summer (Houde et al. 1979).

SUMMARY

The inshore zone between Cape Romano and Cape Sable,

Fla., was a spawning ground and nursery for a variety of

fishes important to fisheries during our study. Larvae of

recreationally and commercially important species present in

the inshore zone were Paralichthys albigutta, Elops saurus,

Mugil cephalus, Bairdiella chrysura, Cynoscion nebulosus, Pogonias cromis, Sciaenops ocellatus, Scomberomorus maculatus,

Archosargus probatocephalus, and Lagodon rhomboides. Larvae of 27 other species were also identified.

The occurrence of larvae ~3.5 mm from the 10 most abundant

families indicated the location and time that some of these

fishes spawned, as well as the direction of larval transport.

Some of these small larvae were distributed about equally

among the most-seaward, middle, and most-landward stations

in the inshore zone (which suggested spawning throughout the

~1O m depths), while the smallest larvae of other fishes were

caught mainly at the most seaward stations (which suggested

spawning in the :;,,10 m depths). Fishes that seemed to spawn

somewhere in the inshore zone during a certain period (months

indicated in parentheses) were: Clupeids (May and August),

engraulids (August), Gobiosoma spp. (August), Microgobius

spp. (August and November), Bairdiella chrysura (May and

August), Cynoscion nebulosus (May and August), Cynoscion

spp. (May. August, November, and February), Menticirrhus

spp. (May, August, and November), Pogonias cromis (November), Sciaenops ocellatus (August), Chloroscombrus chrysurus

(May and August), Oligoplites saurus (May and August),

Symphurus spp. (May and August), and Achirus lineatus (May,

August, November, and February). Fishes that seemed to

spawn near the most seaward stations during certain months

were: Orthopristis chrysoptera (May, August, November, and

February), gerreids (May and August), and Prionotus spp.

(May, August, November, and February). The occurrence of

1) the smallest larvae at the most seaward stations, and 2)

larger larvae at the more landward stations indicated eastward

(offshore to inshore) larval transport.

There were great differences in the total number of eggs and

larvae and in diversity of larvae between our two zones. Most

eggs (95.9%) and larvae (97.9%) were collected at the 24

inshore stations. Larvae of 37 families, 47 genera, and 37

species were collected in the inshore zone (Tables 11-14).

Larvae from only 20 families, 21 genera, and 14 species were

collected in the estuarine zone (Tables 15-18). All larvae that

were found at estuarine stations were also found at inshore

stations.

Salinity was one ofseveral environmental factors that probably

limited the numbers of eggs and larvae in the estuarine zone.

Of the three parameters we measured. salinity was the most

variable, especially in the estuarine zone. When estuarine

abundance of eggs or larvae, or both, was highest, salinity was

moderately high. Nine of the 16 estuarine stations (1, 2, 5, 7,

8, 11, 14, 15, and 16) produced abundances of > 10 eggs or

larvae under 10 m2

; salinity ranged from 20.7 to 37.6 ppt during

the periods of this highest estuarine abundance (Table 6, Figs.

2,3). Station 13 produced no eggs and very few larvae and had

the lowest average salinity in the estuarine zone. The 10 most

abundant families were usually collected at stations with

moderately high salinities (Table 7). During a drought in May

1971, high-salinity waters which intruded into the estuarine
zone probably carried some larval fish into that zone from

inshore waters.

For the 3 mo of the j -yr period when our egg and larval

catches could be compared with those from the offshore statiuns.

our inshore stations had as high. and usually higher, abundances

of eggs and larvae. The only identified fishes for which catch

comparisons could be made were the clupeids, sciaenids, and

carangids. In general, the larval catches of these three families

from Houde et al. (J 979) were similar to ours; most of these

fishes had apparently spawned within 93 km of the beach at

depths <30 m during May and August of 1971 and February

of 1972.

Our results indicate the value of the inshore zone as an

important spawning area for many species of fishes. Houde et

al. (1979) concluded similarly for the offshore area. Lindall et

al. (1973) showed the importance of the estuarine zone as a

nursery for juvenile fishes. Thus, the entire aquatic region

adjacent to the Florida Everglades is of vital importance to the

well-being of numerous species of fishes.
