EXECUTIVE SUMMARY

Lake Mohave currently supports the vast majority of wild razorback suckers in the Colorado 

River basin. The first few years following the closure of Davis Dam, ecological conditions 

allowed the survival of 100's of thousands of young razorback suckers in the new reservoir. This 

represented the last notable recruitment for the species. Measurable survival has not occurred 

following the establishment of the reservoir's sport fishery. Unfortunately, juveniles seek and 

use the same areas inhabited by large predators such as largemouth bass and channel catfish. As 

juveniles become sexually mature, increased activity may lead to additional losses from 

hydroelectric entrainment or water diversion.

Ten adult and six juvenile razorback sucker with sonic transmitters were released and tracked in 

Lake Mohave between November 1994 and July 1997 to determine habitat use and migratory 

behavior. Individual movements and ranges_yaried, but adults exhibited both pre- and post 

spawning migrations. Adults assembled in early December between river kilometer (RK) 26 and 

RK 90 (Horse Shoe Rapids) with spawning aggregations that often numbered in the hundreds. 

Tagged adults spawned between mid-January and March at multiple spawning sites.

Post-spawning movements were as prevalent as pre-spawning migrations as adults disbursed 

toward summer ranges. Six fish (60%) used the area between RK 69 and RK 50 where 

hypolimnetic water released from Hoover Dam mixes with Lake Mohave waters. Two adults 

spent summers along the Nevada shoreline in Cottonwood Basin (RK 26 to RK 32) while the 

two remaining fish used both areas. Adult territorial ranges averaged 39 km (17.8 to 72.4 km) 

and were normally found between RK 26 (Nine Mile Cove) and RK 69 (Chalk Cliff Lights).

The reservoir's longitudinal thermal gradient did not influence geographical distribution. Fish 

were typically found within 50 m of shore and at depths between 3.1 and 16.8 m. Although 

razorback suckers moved vertically in the water column, no correlation was found for depth with 

time of day. Adults utilized a wide thermal range and may regulate body temperature with depth. 

Fish inhabited shallower depths in early summer (June) and autumn (October) compared to the 

warmer months of July and August. Body temperatures of razorback suckers typically ranged 

between 18 and 22 °C when surface water temperature in the reservoir peaked at 30 °C during 

the summer.

Adult razorback suckers return annually to select spawning sites along the wave-washed rubble 

shoreline. However, nine of 10 sonic-tagged fish were found at several spawning areas, 

regardless of where they were initially captured. After spawning, some individuals appeared to 

also have fidelity to specific areas of Lake Mohave during the non-spawning season, suggesting 

they may exhibit a home range.

m
Hourly movement rates showed females were significantly (P=.05) more active during spawning 

than males. Apparently male razorback suckers congregate and remain on, or close to, spawning 

sites throughout the spawning season. Females on the other hand joined the males only when 

ready to spawn and left the site when the spawning act was completed. They appeared to wander 

between specific spawning groups and may spawn with various males that would contribute to 

genetic diversity.

Preliminary information on juveniles suggested they are cover oriented and exhibit migratory 

behavioral quite different than adults. Juveniles traveled substantial distances (>5 km) 

immediately following release, but with time their movements became less erratic and more 

closely associated with shore and protective cover. Juveniles typically found refuge in shallow, 

vegetated coves where they often remained sedentary for days and some for weeks. One young 

razorback sucker (3-yr) became quite active during the 1995 spawning season, traveling 

downstream to within 3 km of Davis Dam and then moving upstream to within 8 km of Hoover 

Dam, a minimum distance of 145 km.

Lake Mohave serves as the largest refugium for adult razorback sucker. It provides additional 

research opportunities that merit consideration. Further research is recommended on 

predator/prey relationships between the early life stages of razorback sucker and introduced 

predators. The migratory behavior of sub- or young adults also needs to be examined to 

determine if that life stage is more susceptible to entrainment, passage, or stranding. Lastly, we 

suggest investigations into the influence that reservoir fluctuations have on predatory distribution 

and densities in shallower habitats used by juvenile razorback suckers. In sight into these 

interactions may increase stocking survival by introducing fish at times or locations where 

predators may be inactive or disbursed.

INTRODUCTION

Most research on wild razorback suckers has dealt with adults, and much of the research focused 

on the relic population in Lake Mohave (Minckley 1983, Langhorst and Marsh 1986, Marsh 

1987, Mueller 1989, Bozek et al. 1990, Minckley et al. 1991, Mueller 1995, Marsh 1997) and a 

small population found in the Green River, Utah (McAda and Wydoski 1980, Tyus 1987, Tyus 

and Karp 1990, Modde 1996, Modde et al. 1996, Modde and Wick 1997). Less is known about 

early life stages. Detection, movement, and behavior of larval suckers has been reported 

Minckley (1983), Langhorst and Marsh (1986), Horn et al. (1994), Mueller et al. (1995), and 

Muth (1995). Recent information on wild juveniles has been limited to a few, rare collections 

(Marsh and Minckley 1989a, Minckley et al. 1991, Gutermuth et al. 1994, Modde 1996, Mueller 

1996, Modde and Wick 1997, Holden et al. 1997).

Most observations have occurred during the spawning period when razorbacks are most easily 

found and captured. Razorback suckers in Lake Mohave aggregate along shoreline between 

January through March to spawn over wave-washed alluvial terraces of sands and gravels. The 

majority of spawning occurs in the main basin of the reservoir but, occasionally, small spawning 

aggregations are observed in the upstream riverine portion of the reservoir (Minckley 1983, 

Mueller 1989). Some studies in the Upper Basin (Tyus 1987, Tyus and Karp 1990) suggested 

razorbacks exhibited fidelity to a specific spawning site, but these data have been inconclusive.

Less information is available on habitat use during non-spawning periods. Following spawning, 

Lake Mohave suckers were generally thought to disperse. Many can be found downstream of 

Hoover Dam (RK 97-103) and large schools have been seen on the surface of the main reservoir 

(Mike Burrell-NDOW personal communique). It was unknown whether these areas represent 

important summer habitat or if individual fish have specific home ranges.

Razorbacks are long-lived, many over 35 years of age and believed to be nearing the end of their 

estimated lifespan (Minckley et al. 1991). Population estimates conducted during the past 

decade has shown a 60 percent decline in the reservoir's population (Marsh 1995). While adults 

are still common, juvenile suckers are rarely collected. Information on juvenile razorback 

suckers is virtually nonexistent because of their scarcity. Nocturnal behavior and use of dense 

aquatic vegetation was reported for cove-reared fish (Mueller and Marsh 1993). Young suckers 

hid in aquatic vegetation during the day, but became active at night and less reclusive as they 

matured (Ryden and Pfeifer 1996). Modde (1996) reported collecting young razorback suckers 

from a depression wetland suggested that earlier speculations (Tyus and Karp 1990) of 

floodplain habitats may be important nursery habitat. To our knowledge, only six juvenile 

suckers have been collected from Lake Mohave in the past 20 years, and these may have been
captive-reared fish from previous stockings (Marsh and Minckley 1989a).

The Native Fish Work Group formed as a coalition of concerned state and federal agencies for 

the purpose of stocking 50,000, juvenile razorback suckers to replace the old population that was 

dying out in Lake Mohave (Mueller 1995). Stocked fish are monitored to determine the 

appropriate sizes needed to ensure adequate survival. Preliminary information suggests that 

approximately 57% over 20 cm have survived (Marsh 1997). Predation is believed to be a major 

factor that limits recruitment from natural spawning. Survival is size dependent but other factors, 

such as time and location of stocking, cove availability, predator densities, and behavioral traits 

that could also impact survival.

The purpose of this study was to gain a better understanding of the migratory behavior and 

habitat used by juvenile and adult razorback suckers in a reservoir environment. As adults 

become rare and more difficult to capture, information regarding their movements and habitat 

use will become more important in monitoring populations. In addition, understanding habitat 

use and behavior of juveniles will allow assessment of predation, stocking protocols, and factors 

that can enhance survival and recovery.

METHODS 

Study Specimens

Adults-Adults were trammel netted at Yuma and Tequila coves (Figure 1, RK 34& 39) during 

November 6-7, 1994. Five males and five females were selected and held at each site for surgery 

the following morning. The Yuma Cove fish were surgically implanted and released on 

November 7th and the Tequila Cove fish were implanted and released on November 8th. Adults 

averaged 609 mm (555-680 mm) in total length and 2.78 kilograms (1.75-4.21 kg). Individual 

data pertaining to length, weight, PIT tag numbers, sonic transmitter code, release location, and 

distances moved are summarized in Appendix A.

Juveniles Twenty five juvenile suckers were taken from grow-out ponds and held in holding 

facilities at the Bureau of Reclamation laboratories in Boulder City, Nevada. The fish were later 

transported by truck and by boat on November 22, 1994. Fish averaged 338 mm (315 to 392 

mm) and 369 grams (296-598 g). The juveniles were released in groups of four fish at: Red 

Light Cove (RK 10), Dandy Cove (RK 17), Owl Point (RK 45), Double Neck Cove (RK 71), and 

Cross Current Rapids (RK 92). Pertinent information is summarized in Appendix A.

Telemetry Equipment

We determined a 30+-cm sucker was capable of carrying a 6 gram, 16 X 5 5-mm sonic 

transmitter (Sonotronics model CTT-83-2) (Knowles 1994). Appropriate transmitter size for
juvenile suckers was determined by examining the volume of the abdominal cavity in museum 

specimens at Arizona State University. Transmitters ranged in size from 8x35 mm to 18 x 70 

mm with life spans ranging from 45 days to 48 months. While smaller transmitters are less 

stressful to fish, there is a substantial trade-off between transmitter size and performance with 

weaker signal strength and shorter the battery life with smaller transmitters.

Transmitters operated on a frequency of 73 kHz and produced a code of pulses broken by pauses 

(e.g. 249 would be 2 pulses-pause, 4 pulses-pause, 9 pulses-pause, repeat sequence). Battery 

longevity was estimated to be about 14 months and signals had an average detection range of 

1,000 meters. The transmitters also provided body temperature with an accuracy of ± 0.25 °C 

through a measurable pulse interval.

Surgical Procedures

Surgical procedures were similar to Hart and Summerfelt (1975) and Tyus (1987). Fish were 

anesthetized in a tub containing approximately 80 L of a 0.1 g/L mixture of tricaine 

methanesulfate (MS-222). When the fish lost equilibrium, it was positioned belly up in a 

specially designed surgical cradle. Water was passed over the gills to provide oxygen and to 

keep the body moist. Anesthetic bath was used during the first half and fresh water was used 

during the last half of the operation to minimize the effect of anesthesia and speed fish recovery.

Transmitters and passive integrated transponder (PIT) tags were sterilized in 70% isopropyl 

alcohol and 10% betadine. A 30-40 mm, medio-lateral incision was made slightly anterior and 

dorsal to the left pelvic fin. The transmitter was inserted toward the posterior of the abdominal 

cavity so that it rested on the pelvic girdle. The incision was sutured with 4-5 knots using 3-0 

Ethilon black monofilament nylon and a FS-1 cutting needle.

The surgical process for individual fish required approximately 7-12 minutes. Anesthesia took 

affect in about 2-4 minutes and surgery normally required 3-5 minutes. The fish remained docile 

and incisions caused minimal bleeding. Following surgery, fish required from 1 to 10 minutes to 

recover from the anesthesia. Fish were released when they regained their motor skills.

External Attachment

Microtransmitters (8 X 35 mm, 45 day) were externally mounted to five juvenile suckers on 

October 20, 1995. Equipment was sterilized in alcohol and the fishes dorsal keel was swabbed 

with betadyne. Two sutures were tied approximately 20 mm apart on each transmitter and their 

knots were glued. Needles were threaded through a plastic backing plate about 1 cm below the 

dorsal keel. The wound was treated with neosporium and the sutures were tied together with 2 

square knots.

External attachment of sonic transmitters required approximately 30 seconds. Three fish were

3
released with approximately 200 other juveniles in a small protected cove adjacent to Nellis 

Cove (RK 26). The remaining two fish were transported to a location cove near Sidewinder 

Cove (RK 14) on the Arizona side and released with another group offish. The fish averaged 

315 mm (303-328 mm) in total length and weighed approximately 350 grams (288-406 mm). 

Specific information is summarized in Appendix A.

Survey Design

Weekly surveys were conducted by boat using a global positioning system (GPS). A transect 

grid was developed using 71 GPS way-points or "listening stations" (Figure 1). These waypoints were established at 1,600 meter intervals, which standardized our survey design and 

provided continuity and overlap (1,000 meter range). The pre-established way-points were 

programed into the GPS's navigational program. Surveyors simply navigated between waypoints, lowered a directional hydrophone into the water, and listened for transmitter signals.

Signals were detected using a DH-2 hand held, directional hydrophone, a USR-5W ultrasonic 

receiver, and headphones. The receiver had a digital readout that provided the time interval 

between signals, which correlated to the fishes body temperature.

Surveys required two days to cover the entire reservoir. Two complete surveys were conducted 

each week for 18 months. Alternate areas of Lake Mohave were examined during both day and 

night. When fish were detected, surveyors triangulated the fish as closely as possible without 

disturbing it. Fish location (latitude and longitude), body temperature, and estimated distance 

from shore were recorded. A Hydrolab was used to measure vertical water temperature profiles.

Battery life of several transmitters exceeded the 14 month life expectancy. Scheduled surveys 

continued until mid-April 1996, however, additional information was collected through July 

1997 on an intermittent basis.

Data Analysis

Geographical information was provided using digitized shoreline profile maps of Lake Mohave 

and the geographical information program (GIS) ARCINFO (TM). Using ASCI files developed 

for each fish, the program calculated the distances between all locations where that particular fish 

was found. The output provided movement rates in m/day, total distance traveled, actual maps of 

movement, and seasonal distribution offish (Appendices B & D). Rate measurements and 

distances from shore were transformed into single classification frequency distributions. Each 

observed datum were summarized by particular classes. Movement rates (m/day) of both males 

and females were examined for the periods between January 31 and March 15 in 1995 and 1996, 

to determine if there were differences in movement patterns between sexes (F-test).

To determine fidelity to inshore habitats, ARCINFO was used to determine the amount of area in 

the reservoir at specific distances from shore. Percentiles of available surface habitat were 

compared to the percentile of fish use within specific zones via chi square test (Sokal and Rolf 

1981).

Comparisons of shoreline habitat utilization, movement rates, and area affinity were divided into 

spawning and non-spawning periods. These periods were defined based on information and 

observations reported for razorback suckers in Lake Mohave (Minckley 1983, Minckley et al. 

1991, Bozek et al. 1990, NFWG unpublished data). The spawning season can vary depending 

upon weather and flow conditions. Staging of spawning aggregations have been observed as 

early as November and larval suckers have been collected into April. For the purposes of this 

analysis, we defined the spawning period as being from November through April and the nonspawning period from May through October.

RESULTS 

Data Base

The database is presented in Appendices A-D which details information on all 45 fish (20 adults 

plus 25 juveniles) used in the telemetry study. We felt analysis could be biased by unhealthy 

fish, so only movement data from the 10 adults and 1 juvenile that remained active through the 

initial 14 month period for the analysis. Nearly 2,000 detections offish movement were 

recorded, of which 637 represented daily detections of the eleven surviving fish. Hourly tracking 

information added over 1,000 observations to the database. Over 800 recordings of body 

temperature in razorback suckers with 147 correlated to depth through vertical water temperature 

profiles acquired with the Hydrolab (Appendix C). These data represented our most accurate 

information on depths occupied by fish.

Information was also collected from the 5 juveniles that were externally tagged with 45 day 

transmitters. Four of the five fish were tracked for the duration of the transmitter life.

Fish Movement

Adults Fish movements were not only variable but quite distinctive by sex and among 

individuals (Figures 2-11). Both males and females exhibited the ability to travel substantial 

distances in a short time span. One fish (#348) traveled more than 17 kilometers in fewer than 

24 hours while some fish remained in the same general locations for weeks. Adult daily 

movement rates averaged 527 m/day (242-788 m/day). Females exhibited a slightly higher rate 

(x=582 m/day) compared to males (x=445 m/day)(Table 1). Maps of individual fish movements 

are summarized in Figures 2-12 and provided in detail in Appendix D.

Spawning Movements Movements of fish during the peak of spawning, January 31 to March 

15 were examined for both 1995 and 1996. We compared the daily average movements (m/day) 

for each sex. Parametric comparison of male and female movement rates indicated females were 

significantly (Anova/Fj,8=6.79, P=0.0314) more active than males. During this 6-week period, 

females exhibited individual movement rates of 721, 444, 453, 412, 444, 284 m/day, which was 

slightly lower than their year-round total (x=460 versus 582 m/day) average. The four males on 

the other hand averaged 409, 281, 32, and 31 m/day, all below their annual average (x=188 

versus 445 m/day).

Range Fish were found occupying areas that encompassed known spawning sites and summer 

habitats (Figure 12). The average linear range of the 10 adults was about 39 km (18 to 72 km). 

Females ranged further than males, both up and down reservoir. Their range averaged 42 km 

(29-72 km) compared to 35 km (18-51 km) for males.

Hourly and Monthly Movement Rates Data were examined to determine trends in hourly or 

seasonal movement by adult razorback suckers. No significant trends were identified. Hourly 

data suggested fish might be slightly more active during mid-morning (9:00 to 10:00 am) in the 

summer. A similar analysis was preformed for the monthly averages but variability was high. 

However, months when individual fish movement exceeded 1,000 m/day, occurred immediately 

after release and following both spawning periods (Table 2).

Juveniles The juvenile (#2273) exhibited a very different trend. Shortly after release at Owl 

Point (RK 47) the juvenile (a 2 yr-old) was found 2 km from the release site in a shallow, 

vegetated cove. The fish remained relatively stationary for 21 weeks and then slowly moved 

down toward Arizona Bay (RK 40). In November 1995, its movements increased dramatically, 

traveling a minimum of 145 km. The fish moved to within 3 km of Davis Dam and then was 

found within 8 km of Hoover Dam when surveys resumed in 1997 (Appendices B & D).

Movements of the 5 (YOY) juveniles were highly erratic following release when fish swam 

around and across the reservoir's pelagic zone. Migratory rates for all 5 fish exceeded 1,000 

m/day (range 1,193 to 3,750 m/day) during the first 10 days following release (Figure 13). After 

the second week, fish moved along the shore and were found in protected coves (Table 3). 

Average movement rates for 5 juvenile razorback suckers in Lake Mohave was between 319 and 

1,011 m/day for a 50-day period following stocking.

Habitat Use

Temperature Preference Body temperatures varied according to the location offish within the 

reservoir. Water temperatures above Willow Beach had a narrow range (12-16 °C) regardless of 

season because of the cold hypolimnetic releases from Lake Mead. However, further 

downstream the lake stratified during the summer, with water temperatures ranging from 1 5 to 

nearly 30 °C.

Temperature data were obtained from 570 fish contacts over the first 15 month period following 

tagging and release. Razorback suckers were found through a wide temperature range (12 to 28 

°C) (Figure 14). However during the summer, adults preferred temperatures that averaged 

between 18 to 22 °C. They seldom were found in water temperatures >25 °C. Hourly tracking 

indicated that fish moved vertically in the water column but there were no correlations for depth 

with time of day. Temperature data for juvenile #2273 demonstrated that this fish preferred 

shallow, warm, protected coves (Appendices B & D)

Table 4 presents the average depths and ranges for the 10 adult and one juvenile fish. While the 

depths are highly variable, the seasonal temperatures recorded for these fish were not, averaging 

between 18.0 and 20.9 °C for the adults.

The thermal characteristics of Lake Mohave varied, with the lower portions of the reservoir being 

strongly stratified. Accordingly, water temperature at a specific depth also varied depending 

upon where the measurements were taken. For instance, a fish seeking out a temperature of 

18 °C during the summer would find that thermal regime close to the surface at RK 72, while at 

RK 32 that temperature would be found at a depth nearer to 10m. We simply did not collect 

the data required to describe the thermal dynamics of the entire reservoir or attempt to make 

correlations of depth and temperature by month. Both are highly variable, but it appeared that 

adults may have had a stronger preference toward water temperature, rather than depth (Table 4).

Shoreline Fidelity-Both juvenile and adult razorback suckers exhibited a significant fidelity for 

inshore habitats during the entire year (P<.001, Chi Square test). Fish were typically found 

within 50 m of shore. Fidelity was most pronounced during the spawning season when average 

distance from the shoreline was less than 30m. Fish tended to move off-shore following 

spawning (July-November) in concert with warming surface water temperatures.

Depth--We collected 147 vertical temperature profiles at the exact location where fish were 

detected. These data were collected from May through November of 1995, when the reservoir 

was thermally stratified and represents our most accurate information on depth. The temperature 

data suggested fish were usually found at depths less than 10m, but on one occasion a fish was 

deeper than 30m. Individual fish were found at average depths that varied between 3.1 and 

16.8 m (Table 4). Seasonally, fish moved closer to the surface during early summer and then 

migrated deeper during mid-summer (Appendix C). As surface water temperatures cooled in 

late summer, fish once again moved closer to the surface at depths averaging <15 m.

Geographical Fidelity-There were definite areas of the reservoir where adults preferred to spawn 

and reside during non-spawning periods of the year (Figures 15 & 16). Adults seldom were 

detected downstream of South Basin Light (RK 21) or upstream of Monkey Hole (RK 77). In 

Cottonwood Basin, there was strong preference to the Nevada west shoreline between Nine Mile 

and Six Mile coves. This area was used during the spawning season by three fish (#339, 465, 

384) and during the summer by five fish (#375, 258, 276, 384, 465). Tequila Cove (RK 34) was 

visited by all spawners except for fish #2228. The most heavily used area in the reservoir was 

between RK 39 and RK 47. The Arizona shoreline was used extensively by all fish during the 

spawning season and adults were seldom found along the more vegetated Nevada shoreline. 

This vegetated portion of the lake was initially used for several weeks by juvenile #2273.

'' Average of weekly averages

The most popular 1-mile reach of the reservoir was at Owl Point (RK 45). This area was used by 

all ten of the study fish during spawning season (Figure 15) and by four fish (88, 348, 366, 375) 

during extended periods of the non-spawning season (Figure 16). Another major use area was 

located between Chalk Cliff Lights (RK 69) and Fire Mountain Lights (RK-60) and represented 

the cold/warm water interface where Hoover releases mix with the warm reservoir waters. Seven 

of the suckers (348, 366, 2228, 339, 276, 88, 375) used this area during the summer. On one 

warm, calm day, we observed an average of 6 razorback suckers per kilometer at the surface in 

this area.

These areas played an important role in the home range of all ten adults. Some areas were used 

specifically for spawning while others were only used during non-spawning periods. Some 

areas, like Cortonwood Basin and Owl Point were used year round by some fish, while heavily 

used spawning areas, such as Tequila and Yuma coves were vacant during the summer.

DISCUSSION

Lake Mohave may not be considered pristine habitat for a riverine species. However, 

opportunities to study behavioral and habitat use would be difficult in natural river settings. 

Studies in riverine systems have been challenged by the scarcity of fish and the logistics 

associated with remote riverine habitats. Our fish numbers were not significantly different from 

previous research, but study conditions were unparalleled that provided us an unprecedented 

database. Reservoir water visibility exceeded 10m, which unlike river conditions, allowed 

researchers to easily find spawning congregations, observe spawning, document reproduction 

(collect sucker larvae), and observe individual fish. These fish had a much broader and less 

fluctuating range of physical parameters to choose from compared to riverine conditions. Lake 

temperatures ranged from 12 to 30 °C, flows ranged from none to 3 m/sec, depths could exceed 

40 m, and fish had the opportunity to use both littoral and pelagic habitats.

It's noteworthy that the only significant recruitment recorded in recent history occurred in 

reservoir, rather than river habitats (Minckley et al. 1991). Lake Mohave once was the 

prominent nursery for 95 percent of the wild razorback suckers that still survive. This fact 

illustrates the adaptability of the razorback sucker to use a wide range of physical habitat 

conditions. While adults have successfully spawned in a variety of conditions ranging from 

small ponds to cold hypolimnetic tailwaters (Minckley et al. 1991, Mueller 1989, 1995), there is 

no measurable recruitment suggesting their young do not survive. The dependency of young 

suckers on shallow, warm, shoreline habitats make them highly susceptible to normative 

predators. Unfortunately, the fish has failed to cope with exotic predator introductions. This 

sobering fact has until recently been ignored or discounted in an arena where fishing license sales 

primarily funds management programs.

Adults

Both adults and juveniles used the broad, shallow, shoreline habitats found in Arizona and 

Cottonwood basins and generally avoided the deeper, canyon habitat typical of the lower 

reservoir. Fish were seldom tracked together until the spawning season (McAda and Wydoski 

1980). Adult razorbacks were quite mobile, but exhibited movement rates and ranges similar to 

those reported in riverine habitats (Tyus 1987, Kaeding and Osmundson 1988, Marsh and 

Minckley 1989b, Tyus and Karp 1990, Ryden and Pfeifer 1995 and 1996, Burdick and Bonar 

1997, Modde and Wick 1997). Adults exhibited various degrees of sedentary and roaming 

behavior similar to those reported for other stream fish (Funk 1955).

Spawning Migrations Spawning razorback suckers migrate (Jordan 1891, Hubbs and Miller 

1953, Sigler and Miller 1963, Tyus 1987, Tyus and Karp 1990, Minckley et al. 1991, Modde 

and Wick 1997). We observed prespawning movements both up- and down-lake that were 

similar to movements reported in the Green River (Modde and Wick 1997, Tyus and Karp 1990, 

Tyus 1987). Some spawners traveled up to 50 km prior to, and during spawning, to form or join

17
large spawning aggregations.

It has been speculated that spawning migrations may be triggered by the ascending spring 

hydrograph (Tyus 1987, Tyus and Karp 1990). However, under reservoir conditions where flow 

has a minimal influence, we found suckers exhibited the same reproductive characteristics, 

behavioral traits, and migrations as reported for riverine populations.

Another attribute unique to the reservoir population is the spawning duration. Spawning in the 

Green and Colorado rivers has been reported to take between 4 and 6 weeks (Tyus 1987, Tyus 

and Karp 1990, Modde and Wick 1997) while reservoir spawning continued for 10 to 14 weeks 

(Medel-Ulmer 1983, Langhorst and Marsh 1986, Mueller 1989, Minckley et al. 1991). 

Spawning is usually associated with fish ovulation and gamete release and is normally reported 

in terms of days and even weeks. However, an examination of migration trends (Figures 2-12) 

suggests a broader interpretation is needed. Pre- and active spawning may actually last up to 

6 months. Razorbacks migrate and stage near spawning sites as early as November and stay in 

those areas until late March or April. This suggests that non-hydraulic factors, such as 

temperature and photoperiod (Minckley et al. 1991), may not only trigger spawning, but 

conceivably may also influence its duration.

Spawning Site Fidelity Tyus and Karp (1990) reported spawning site fidelity in the Green River 

basin and suggested the population structure might be segmented and made up of multiple 

"stocks." Later Scholz (et al. 1992) and Modde (et al. 1996) suggested there was evidence that 

fish might be imprinted to specific sites, but the results of those imprinting studies were 

inconclusive. Modde and Wick (1997) later suggested razorback suckers might actually spawn 

at several sites in the Green River. Studies of the Colorado squawfish suggest these native fish 

exhibit a fidelity for a particular river reach but may select spawning sites with certain 

characteristics based on stream flow (Osmundson et al. 1997).

The extended spawning season and survey conditions allowed us to more closely monitor 

individual movements. We found spawners to be highly social, forming aggregations 

numbering hundreds and possibly thousands of fish (Minckley et al. 1991). Adults returned 

annually to popular spawning sites, but, they also used other spawning sites as well. While we 

cannot confirm that spawning actually occurred, there is a high probability based on the presence 

of sucker larvae (Burke unpublished data) and the known fecundity of the species (Minckley 

1983, Minckley et al. 1991). Females may produce an average of 100,000 ova, but release only a 

few eggs during separate spawning events. Our data show that spawning females are more 

mobile than males. Ripe males remain at specific spawning sites while females join them when 

they are ready to release their eggs (Mueller 1989), a common behavior among other catostomids 

(Moyle 1976). Females that ovulate over an extended period could spawn with numerous males 

at different locations. This behavior, combined with larval dispersal helps explain the high 

genetic variability described in this population (Dowling et al. 1996).

Post-Spawning We found post-spawning migrations were as prevalent (distance and rate) as

18
pre-spawning migrations. Valdez and Wick (1983), Tyus and Karp (1989) and Modde and Wick 

(1997) reported that following spawning, razorback suckers moved into flooded lowlands which 

were speculated to provide more abundant food and warmer habitats. Holden (et al. 1997) 

reported similar movements in Lake Mead where adult razorback suckers moved from spawning 

areas into the more productive inflow areas of Las Vegas Bay and the Overton Arm.

We witnessed a similar trend in Lake Mohave. The majority (60%) of our fish migrated up 

reservoir after spawning toward the interface zone from Lake Mead. The reservoir provides 

warmer temperatures elsewhere, but, this mixing zone is limnologically more productive (Baker 

and Paulson 1980). Algal production in this cold-warm water interface is quite noticeable 

compared to other areas of the reservoir. Marsh (1987) reported that razorback suckers pursued a 

diet of planktonic crustaceans, diatoms, filamentous algae and benthic materials that are present 

in the mixing area. Wydoski and Wick (1998) suggested adult razorback suckers may feed on 

zooplankton in highly productive floodplains to regain their body condition after spawning. In 

Lake Mohave, adults were more active (rn/d) after spawning and were found closest (<6 m) to 

the surface where plankton is most abundant. The need to recover body reserves after spawning 

may influence the their spatial distribution in the reservoir.

Some fish exhibited a strong spatial fidelity to specific locations in the reservoir while movement 

patterns for others were less obvious. For instance, the distance between spawning and summer 

resting areas for some fish (348, 258, 375, and 366) averaged about 20 km. Once located in 

either their spawning or summer habitats, some fish became sedentary, moving less than ± 2-5 

km for 1-2 months. The remaining six fish moved more with some roaming over 30 km. Some 

of this movement may have been in response to changes in the location of the warm/cold 

interface zone. High discharges from Lake Mead and fluctuating reservoir elevations can cause 

this interface zone to migrate up and down the reservoir as much as 20 km and could influence 

fish distribution and movements (Baker and Paulson 1980).

We observed considerable territorial overlap during this study. Nine of the ten fish, regardless of 

whether they were captured initially in Yuma or Tequila Cove used both sites during the 

spawning season. The only exception was fish #2228 whose spawning range was between Yuma 

Cove (RK 39) and Horseshoe Rapids (R). This fish appeared to spawn in both the warm and 

cold portions of the lake. While the spawning areas used by the majority of fish overlapped, the 

areas used by fish during the summer did not and, in some cases, were at opposite ends of the 

reservoir. This homing pattern of spawning and non-spawning populations was described by 

Gerking (1958) who stated; "Spawning migrations are directed toward a specific location.... 

(while) the fish are usually scattered over a wide area during the non-reproductive portion of 

life."

Adults in Lake Mohave were most active during late morning hours (9:00 a.m.-10:00 a.m.), 

especially during the spawning season. Me Ada and Wydoski (1980) found adults in a gravel pit 

most active during late evening (7:00 p.m.-9:00 p.m.) and late morning (10:00 a.m.-12:00 p.m.).

19
Juveniles

The five juveniles equipped with external (45 day) transmitters were undoubtedly stressed during 

the first few days following stocking. Their behavior appeared abnormal, traveling both day and 

night through wide expanses of the reservoir's pelagic zone. After a few days, fish appeared to 

calm down and were found associated with shore, especially in shallow, vegetative coves. They 

skillfully hid in aquatic vegetation and usually moved nocturnally (Mueller and Marsh 1993).

Unfortunately, only one of the juveniles surgically implanted in this study retained its transmitter 

and remained active. We tracked juvenile #2273 for 20 months. One year following release, the 

juvenile became quite active, moving over 145 km around the entire reservoir. The fish came 

within 3 km of Davis Dam and then turned back upstream and traveled more than 80 km into the 

flowing portion of Lake Mohave. This behavior was quite different than the adults that had 

distinctly smaller ranges. However^there is a remote possibility the sucker was eaten by a large 

striped bass since an angler recently harvested a 30 kg striped bass that could have eaten a 50 cm 

razorback sucker. If this was the case, the observed movement was associated with the predator 

rather than the subadult razorback sucker.

Sufficient data is not yet available, but it seems logical to believe that young adults may be more 

active than older adults. Such behavior is reported for young flannelmouth suckers (Chart and 

Bergerson 1992) and young Colorado squawfish, two fishes that also evolved in this river system 

(Osmundson et al. 1997). Tyus (1990) speculated the migratory behavior for Colorado 

squawfish may have evolved in conjunction with long-distance larval drift, and Valdez (et al. 

1982) further speculated that, "A net long-term movement of juveniles (squawfish) must occur to 

populate adult areas upstream, probably in the late young-adult stage,..." We believe similar 

evolutionary factors influenced the distribution and behavior of early life stages of this mainstem 

catostomid. If so, the implications could have significant implications for recovery efforts (Tyus 

1997).

Transmitters Retention

Transmitter retention in adults was as good as, if not better than, similar studies (Creef and 

Clarkson 1993, Burdick and Bonar 1997, Holden et al. 1997 and Richard Bradford (AGFD 

personal communique). Fifty percent of the adults were still actively moving 14 months after 

being release. After 34 months, 6 transmitters and fish were still active. However, results with 

juvenile fish were disappointing. Only one of 20 surgically implanted juveniles remained active. 

Ryden (1997) reported similar problems but found that transmitter expulsion did not necessarily 

result in fish mortality because small razorback suckers shed surgically implanted transmitters 

and survived.

Management Implications and Recommendations

20
The adult razorback sucker population in Lake Mohave appears quite secure with regard to 

habitat requirements and the absence of major threats. The fish we studied generally remained in 

the center portion of the reservoir, away from the hazards of possible entrainment (Davis Dam) 

and remote enough to avoid propeller strike in high recreational use areas (marinas). Adult fish 

generally avoided deeper, canyon habitats which might lead them to Davis Dam.

However, young suckers are at risk to predation by nonnative fishes. Young use shallow, 

vegetated habitats that are also used by non-endemic predators such as red shiner (Notropis 

lurensis), green sunfish (Lepomis cyanellus), bluegill (Lepomis macrochirus), largemouth bass 

(Micropterus salmoides) and channel catfish (Ictalurus punctatus) (Tyus 1997). Predator 

distributions and densities, which historically were controlled by droughts and seasonally low 

flows, have been expanded due to channel degradation, reservoir fish populations, and sport 

-fishery management. We believe the establishment and-spread of nonnative fish predators has 

literally turned nursery habitats into lethal traps for larvae and juveniles. This concept is 

supported by the boom and bust sucker populations which occurred following the inundation of 

lakes Mohave, Roosevelt, and Mead (Minckley 1983). Razorback suckers can successfully 

spawn over a wide range of habitat conditions, however, meaningful recruitment has only 

occurred in the relative absence of non-native predators (Minckley et al. 1991, Mueller 1995).

The second concern we have is in the migratory behavior of juvenile or young adults. The 

limited data we collected combined with the known migratory behavior of flannelmouth suckers 

and Colorado squawfish, suggests that after an initial period of growth, young suckers enter a 

roaming or dispersal life stage. The majority of wild juveniles captured downstream of Davis 

Dam in recent years have been from irrigation or delivery canals (St. Amant et al. 1974, Ulmer 

and Anderson 1985, USFWS 1981, Mueller 1996, Minckley et al. 1991). It has been speculated 

that the survival of these suckers was linked to annual drainage and low predator densities, but, 

the possibility exists that some fish entered the canals as roaming juveniles or young adults.

If so, and dependent upon the extent of these movements, such behavior could have serious 

ramifications to recovery efforts. With the potential loss of the core population in the lower 

basin, recovery may not be possible. Moyle and Nichols (1973) suggested that dams could 

effectively block community dispersal. Possibly the lower basin played a critical role as the 

systems most stable nursery habitat which produced the majority of young suckers that 

periodically repatriate marginal habitats further upstream. Augmentation efforts might also be 

affected if young fish movements make them more susceptible to entrainment, passage through 

dams, and stranding in large agricultural diversions.

We recommend that the following actions be considered:

1. Conduct further research on the migratory behavior of subadult fish. As fish become sexually 

mature, does their roaming behavior subject them to unacceptable losses through entrainment or 

passage into water diversions?

21
2. Examine predator/prey relationships between early life stages of razorback sucker and 

introduced predators. Identify what habitat conditions and predatory thresholds would be 

necessary to insure some measurable level of razorback recruitment.

3. Review existing information and develop a stocking protocol for the lower basin which 

includes not only Lake Mohave but also other portions of the watershed. Prioritize the most 

likely areas in terms of habitat, stream length, and potential threats. Stock suckers as large as 

possible (>40 cm) at times when predators are less active (winter) and examine better methods of 

acclimation and release.

4. Examine the influence that reservoir fluctuations may have on the densities and distributions 

of potential predators. Assess whether current reservoir operations (or modifications) create 

shallow vegetated habitats which depress predator densities and would improve survival of 

stocked razorback suckers. .
