Texas Peacock Bass and Nile Perch: Status Report Texas has 37 man-made reservoirs used to cool electro-power plants and several more are in the construction and/or planning phases. Managing the sport fishery in these reservoirs is difficult because temperate predators are unable to compete with overabundant rough fish populations characteristic in the warmed water of these impoundments. Nile perch (Lates sp.) and peacock bass (Cichla temensis) are two tropical predators under investigation for possible introduction into power plant reservoirs.

Limnological and Ecological Effects of Grass Carp in Ponds The feeding activity of grass carp (Ctenopharyngodon idella) significantly reduced the final biomass of submerged plants in Missouri ponds. Water quality was improved; total alkalinity and pH were sustained at levels more suitable for productivity. Nocturnal oxygen depletion was less severe. and noxious phytoplankton blooms did not develop in ponds stocked with grass carp. Grass carp had no significant effect on abundance of glass shrimp (Palaemonetes kadiakensis); bluegills (Lepomis macrochirus) had a much greater negative effect.

Growth Comparisons and Catchability of Three Largemouth Bass Strains Florida largemouth bass, Micropterus salrnoides floridanus (Le Sueur), northern largemouth bass, M.s. salrnoides (Lacepede), and their F1 hybrid were stocked in a 3. 64-hectare pond, and their growth rates and catchability compared. The hybrid and Florida bass were found to achieve the best growth over a 3-yr period, apparently due to genetic influences rather than environmental factors. Differences in catchability were not observed among the three strains oflargemouth bass.

The purpose of this study was to observe growth, survival, and spatial distribution of the Florida largemouth bass (Micropterus salmoides floridanus) and of the northern subspecies (M. s. salmoides) in an Oklahoma reservoir thermally enriched by a heated effluent from an electrical generating plant. Hatchery-reared fingerlings of both subspecies were stocked in 1974 and 1975 after they were marked with either fluorescent pigments sprayed into the dennis, or, with magnetized metal injected into the nasal cartilage.

Scales and otoliths of the white grunt, Haemulon plumieri, sampled from the North Carolina and South Carolina headboat fishery were examined to determine if they could be used to age the species. Both structures were satisfactory, 76% of the fish examined could be aged by scales and approximately the same percentage by otoliths. Agreement for a given age between otoliths and scales taken from the same fish was 75%. The oldest fish collected was XIII; 589 mm total length. Growth occurred from about mid-March to November.

Standing Crops of Fishes of an Estuarine Area In Southwest Louisiana Standing crop of estuarine fisheries, as determined by extensive rotenone sampling, ranged from 17.6 to 1,605 kg/ha; overall average was 393.8. The most abundant species in numbers were gulf menhaden, Brevoortia patronus (54.6%); anchovies, Anchoa sp. (10.7%); and striped mullet, Mugil cephalus (6.6%). Of the 8,322 kg of fish collected during the study, red drum, Sciaenops ocellata, represented 32.2%, followed by menhaden (16%) and striped mullet (11.5%). First day rotenone samples were not sufficient for quantitating species abundance.

Dynamics of Hybrid Sunfish in Southern Illinois Farm Ponds Control of population density in southern Illinois farm ponds was achieved by stocking F, hybrid sunfish of the male bluegill (Lepomis macrochirus) X female green sunfish (L. cyanellus) and the male redear sunfish (L. microlophus) X female green sunfish with largemouth bass (Micropterus salmoides). Four of 30 ponds sampled were contaminated by nondesirable species from the watershed. Little or no recruitment of the F, generation occurred in ponds containing largemouth bass.

Evaluation of Anhydrous Ammonia For Fishery Management Uses Anhydrous ammonia was applied to ponds at average rates of 18-40 ppm to evaluate its use as a fish toxicant and aquatic herbicide. Ponds contained toxic levels ofammonia for 3-4 weeks after applications, depending on concentration, water temperature and other factors. A regression model was developed to estimate specific dissipation times. Application of15ppm ammonia effected a high percent mortality to all fish species observed. Complete fish kills occurred at approximately 30 ppm ammonia. Any concentration above 15 ppm temporarily controlled most vegetation, regardless of season.

Angling Vulnerability of Esocidae Five yearling northern pike (Esox lucius). muskellunge (Esox masquinongy), or their F, hybrid ("tiger muskie") were stocked in duplicate 0.2-ha ponds in April, 1974. Two additional ponds were stocked with a combination of five fish of each of the three forms. In 58 hours of angling from April to September, northern pike were 3.1 and 4.2 times more vulnerable than tiger muskies and muskellunge, respectively. No fish were caught in 18 hours of fishing from 15 June to 13 August. Repeat catches accounted for 35. 6% of the total catch; hooking mortality was negligible (1.7%).

The Reservoir Committee, Southern Division, American Fisheries Society, undertook to measure the influence of stocked predator fishes on existing fish populations and sport fishing in selected reservoirs through a coordinated interagency study. Field data collection consisted of (1) fish population biomass estimation, (2) limnological survey, and (3) sport fish harvest estimation, with data being collected in 1972 and 1973. Twenty-six reservoirs, totaling 368,000 acres, were included in the project. The work plan used to standardize field data collection is described.

Stocking of Predators in the Predator-Stocking-Evaluation Reservoirs Sixteen of the 26 predator stocking evaluation (PSE) reservoirs were stocked with striped bass during 1967-71 and harvest of them by anglers was recorded in 10 reservoirs in 1972 and/or 1973. Walleye were stocked in nine of the PSE reservoirs and were harvested in six of them during the study period. Probable reasons for stocking success or failure are discussed in the accompanying PSE papers.

Angling Pressure and Sport Fish Harvest in The Predator-Stocking-Evaluation Reservoirs Estimates of angling effort and sport fish harvest in 24 predator-stocking-evaluation reservoirs in 1972 and 1973 indicated mean annual angler-effort was 31.1 hours per acre and total harvest was 18.4 pounds per acre. Harvest-rate was 0.7 fish per hour or 0.6 pounds per hour. Average annual harvest of striped bass was 0.5 pounds per acre; walleye 0.3 pounds per acre. Striped bass harvest was positively related to dissolved solids content and water level fluctuation but negatively related to mean depth. Walleye harvest was positively related to mean depth and negatively to reservoir area.

Estimation of Standing Crop of Fishes in the Predator-Stocking-Evaluation Reservoirs The cove rotenone sample technique was used to estimate standing crop of fishes in the 23 reservoirs selected for the Predator Stocking Evaluation (PSE). Estimates ofadjusted standing crops were derived by expanding the observed standing crop of fish in a cove sample by compensation factors for incomplete recovery of fish in the sample and for different shoreline-open water distributional patterns of various fish species and size groups.

Environmental Conditions and Standing Crops of Fishes in Predator-Stocking-Evaluation Reservoirs Relations between environmental variables and fish standing crops were examined in 1972-73 as part of a Predator-Stocking-Evaluation of reservoirs, sponsored by the Reservoir Committee, Southern Division of the American Fisheries Society. High volumes of flow and increased water exchange rates in 1973 were associated with increases in fish standing crops and changes in the size structure of fish assemblages in some study reservoirs. Reservoirs with higher inherent water exchange rates also supported larger standing crops than those with lower exchange rates.

Satisfactory procedures were developed for the artificial propagation of snook, Centropomus undecimalis, as were methods for capture, care, transport, and handling of the broodfish. Milt stored at 40' F. up to 12 hours was satisfactory for fertilization. Fecundity was determined to be approximately 45,000 eggs per pounds of body weight. Fertile eggs were bouyant at salinities greater than 2(1'/0<> Lack of agitation during the first 6 hours of incubation proved critical for consistent embryo development.

Methods and Techniques for Spawning and Rearing Spotted Seatrout in the Laboratory Spotted seatrout were maintained in an indoor tank (6 x 3.3 x 1.5m). Temperature and light were adjusted to simulate the seasons. When the light regime equaled 15 hr light and 9 hr dark and the temperature was 26 C. the spotted seatrout began to spawn. They continued to spawn during each of 13 consecutive months for a total of 82 spawns. Eggs were collected from the filter box with glass beakers and placed in 74-liter aquaria. The eggs hatched after 18 hr. Newly hatched seatrout were fed rotifers (Brachionis plicatilisland brine shrimp (Artemia sp.).

Total dissolved gas, dissolved oxygen, dissolved nitrogen, pH, conductivity, temperature, and turbidity were monitored to determine diel and annual changes in a mariculture pond and in aquaria supplied with water discharged from a power plant. The diel and annual ranges of all hydrological parameters were greater in the pond than in aquaria. Diel patterns were similar in both cases but the amplitude was attenuated in the laboratory aquaria. Gas bubble disease (OBD) developed in 17 marine and estuarine fishes and in grass shrimps in the laboratory.

Effects Of Heptachlor and Toxaphene on Laboratory-Reared Embryos and Fry of the Sheepshead Minnow Flow-through seawater bioassays of 28-days duration were conducted with the organochlorine pesticides heptachlor and toxaphene to detennine their toxicity to and bioconcentration by embryos and fry of the sheepshead minnow (Cyprinodon variegatus). At technical heptachlor measured concentrations of 4.3, 3.5, 2.2, 2.0, and 1.2 u/1 (ppb), test animal survival was 1, 5, 61, 79, and 88%, respectively. At toxaphene measured concentrations of 2.5, 1.1, 0.6, 0.3, and 0.2 1u/1, test animal survival was 10, 85, 79, 88, and 80% respectively.

Commercial Gill Netting and Its Effects on Sportfishes in Texas Reservoirs This study was designed to compare the catch of sport and rough fishes and to determine the survival ofsport fishes captured by commercial gill nets in Texas reservoirs. Commercial fishermen were required to submit monthly reports for 1 yr (April, 1973 through March, 1974) on their rough fish harvest and on the number and species of sport fishes caught and released. The catch was recorded from monthly samples of commercial harvest on Lakes Sam Rayburn, Whitney, Somerville and B. A. Steinhagen and from quarterly samples on Lakes Livingston and Cedar Creek.

Primary productivity and nutrient concentrations were compared between the periphyton community on a freshwater artificial tire reef and the littoral phytoplankton in Smith Mountain Lake, Virginia, during the months of July, August, and September 1974. Primary productivity and nutrient concentration of the periphyton community were several times greater than that of the littoral phytoplankton. The periphyton community was dominated by pennate diatoms and filamentous green algae.

Cost/benefits From the Rotenone Renovation of a 485-Hectare Texas Reservoir To determine the effects of a large-scale rotenone renovation on a fish community and sport fishery, a 5-yr study was conducted on Sheldon Reservoir, a 485-ha Texas reservoir with small sport fish populations and poor fishing. The lake level was lowered and the remaining water treated with liquid rotenone. Gill nets, seines and a creel survey were used before and after treatment to evaluate this renovation. The relative abundance of sport fish populations increased from 17.54% (by weight) before treatment to a high of 46.27% after the renovation and restocking.

Recovery of Marked Fish in Cove Rotenone Samples The use of fin-clips and dart tags for detennining recovery efficiency in summer cove rotenone samples was compared. Using a standardized cove sampling methodology, fin-clipped fish were recovered from 69 coves at an overall rate (%) of 52.4 ± 4.7 (2 S. E.), while in 21 coves 73.6 ± 3.0% of the dart-tagged fish were recovered. As the sample season progressed recovery efficiencies for fin-clipped fish showed a consistent improvement, however, neither seasonal nor year-to-year means was as high as dart-tagged estimates.

Channel Catfish Culture: State of the Art 1976 The perfection of culture techniques for the channel catfish (Ictalurus punctatus) has been aided by the commercial demand for fingerlings, by the fact that the catfish is "precocial" by the time the yolk sac is absorbed, is not cannibalistic, and readily utilizes artificial feeds early in life. Several techniques have been developed for producing catfish fingerlings, but the method that appears most acceptable for the production of large numbers of fingerlings is by the pond spawning/trough incubation technique.

Increasing the Yield of Channel Catfish Rearing Ponds by Periodic Division of the Stock Stocking of small fingerling catfish into rearing ponds at a density to give the optimum number and weight for harvest at edible size gives a low gain per acre per day during the first half of the grow-out period. Use of a much heavier stocking rate initially, with periodic division or splitting of the stock shows promise of significantly increasing the gain per acre per day. Use of two divisions gave a gain per acre per day ofabout 25 pounds for the first phase and 10 pounds for the second.

Status of Commercial Aquaculture in Arkansas in 1975 A telephone and personal survey of all known Arkansas fish producers was made during the first quarter of1976 to determine the extent of change in aquaculture production during the past three years. The survey indicated that although intensive pond production has been reduced by about 4,050 hectares, the economic value since 1972, because of higher prices received for the products, has increased by 16.8% to $24,191,700. Growth in the industry has slowed in recent years due to narrowing profit margins and changes in prices and allotments for other agricultural crops.

The Louisiana Erawfish Industry--Its Problems and Solutions Cultural technology is adequate to produce crawfish in ponds with water quality a main consideration. Occurrence of small stunted crawfish has been reduced by increasing trapping frequency. A mechanized harvester and more efficient traps and bait are needed to relieve labor problems. The processing industry must have a mechanical peeler and utilize traditional shrimp freezing technology to extend shelf life and markets. Marketing is a key to sustained pond production. Prices of crawfish will increase as processors and live market sales compete for the raw product.

A total of 710 largemouth bass was collected from a 4047 ha coastal freshwater marsh in Southwestern Louisiana. Seven age-groups (()-VII) were present in the marsh. Annual increments were smaller for the first 3 years of life when compared to other Louisiana areas, but greater during the remainder of life. Condition factors were comparable to those obtained by other Louisiana authors. Food habits of young of-the-year bass >95 mm in length were not different from age groups I and II. Fish and adult odonates were the principal forage for bass in the summer.

Incidence and Seasonal Variations of Epistylis Among Fishes in North Carolina Reservoirs Epistylis infections were found on 16 fish species in the Yadkin and Catawba River reservoirs in North Carolina during 1974-75. Families most affected were Ictaluridae, Percichthyidae, and Centrarchidae. Highest incidence of the disease occurred during the summer and fall months. The most common infection site among most species of fishes was inside the mouth. A positive correlation was found between total fish length and Epistylis infection rate among Lepomis auritus, Lepomis macrochirus, and Micropterus salmoides.

A Method For Analysis of Differences in Fish Community Species Occurrences The occurrences of the 20 most abundant fish species in impoundments of each of seven rivers were compared using Long's (1963) index of faunal resemblance. Higher order systems, i.e., larger rivers, contain more species than smaller rivers. Also, impoundments of larger river systems tend to be more similar, while those on smaller rivers maintain their unique faunal assemblages.

Stream Trout Fishery Management in the Southeastern United States Trout stream management consists of protection of existing waters from further degradation, and management of the fishery through regulation implementation and stocking programs to manipulate use patterns. The dwindling trout resource is impacted by an increasing number of resource users. Management ofa trout fishery should consider attitudes of trout fishermen expressed in their definitions of quality angling. An area-wide program should be managed to provide a variety ofangling experiences.

Effect of Low Head Impoundments on Ambient Trout Stream Temperatures Data from five northeast Georgia trout streams revealed significant alteration of ambient temperatures by impoundments. A 7.3 ha impoundment releasing water at 3.9 m warmed Anderson Creek a mean 2.2 C during August 1973 and reduced diurnal temperature variation by two-thirds. Surfacerelease impoundments on Bean Creek and Chickamauga Creek warmed ambient temperatures a mean 4.2 C and 3.8 C, respectively, dUring the summer of 1974. Diurnal fluctuations were increased in these two streams.

The Occurrence and Distribution of Larval Fish in the Cumberland River The seasonal distribution of larval fish in the Cumberland River was studied in 1974 and 1975 as part of an environmental monitoring program at the site of the proposed Hartsville Nuclear Power Plant near Dixon Springs, Tennessee. Meter and half-meter diameter nets were used to collect 13,571 larval or young juvenile fish of 13 families during evening hours from April to mid-August. Clupeids, catostomids and Lepomis sp. dominated the collections during both years. Concentrations of larval fish were significantly IP≤ 0.05) higher in the Dixon Creek backwater area than in the river proper.

A Biotelemetry Study of the Movements of the Walleye in Central Hills Reservoir, Tennessee From July, 1974, through July, 1975 the movements of 29 walleye were monitored in Center Hill Reservoir, Tennessee, using ultrasonic telemetric techniques. Seasonally, monitored walleye were most active during the winter and least active during the summer and activity was not correlated with angler success. Diel activity varied from a nocturnal pattern during the summer, to crepuscular during the fall and winter, and no pattern was evident during the spring.

Effects of Grass Carp on Native Fish Populations in Two Florida Lakes Two natural ponds were studied to investigate the effects of introduced grass carp on native fishes. Biologically significant deleterious effects were detennined for both fish populations. Largemouth bass populations were reduced in one pond and substantially altered at the second site. Fish population structures shifted and symptoms of overcrowding were evident. Bluegill numbers increased in both ponds. Warmouth were greatly reduced in one pond. Several species offorage fishes were eliminated.

Performance of an Axial Flow Pump for Lake Destratification A propeller pump was operated for 120 days on a lake of40 ha surface area in north-central Oklahoma in the summer of 1975 to accomplish artificial destratification. The pump created a downf/ow of welloxygenated surface water by means ofa 1.82 m diameter propeller located 1.8 m below the lake's surface. The pump produced a flow of 1.72 m3/sec, equivalent to 12.9% of total lake volume per day, at 17 rpm with a 1.0 h.p. electric motor.

Food Habits of Coastal Marsh Raccoons With Observations of Alligator Nest Predation Food habits of the coastal marsh raccoon, Procyon lotor megalodous Lowery, in Louisiana were studied from June 1973 to August 1974. The raccoon's role as predator of the eggs and hatchlings of the American alligator, Alligator mississippiensis, was also evaluated. Eight hundred and sixty-six raccoon scats were collected from the fresh, intermediate and brackish marsh types, an average of 24 scats per month per habitat type.

Alligator Attacks on Humans in Florida Accounts of reported alligator attacks in Florida are summarized and examined for evidence of patterns that might explain the causes ofalligator attacks. Twenty-two such incidents were found. Three were provoked, circumstances surrounding 3 were unclear, and the other 16 appeared to be unprovoked attacks. Attacks occurred during the warmer months, usually during late afternoon. Most victims were Florida residents between 9 and 16 years old, most were standing in water or swimming, and none were feeding the alligators at the time ofattack.

A Comparison of Native and Introduced Immature Alligators in Northeast Louisiana A telemetric study was conducted on immature alligators (Alligator mississippiensis) in two north Louisiana lakes, Black Bayou Lake and Wham Brake Reservoir, from 10 April, 1975, through 4 December, 1975. Twenty-three alligators, 11 native and 12 introduced from a coastal marsh habitat were fitted with color-coded neck-collar radio transmitters and their daily movements followed with a directional receiver. Minimum home range sizes varied from 0.8 to 321 hectares for all animals with no significant difference being found between range sizes oflocal and introduced alligators.

The Breeding Potential of the Wild Turkey Hen A literature review revealed that little data-based information on the breeding potential of the wild turkey (Meleagris gallopavo) is available. A nine-year study in which the emphasis was on nesting attempted to supply some of this information. We observed 155 nests and found that most hens, including yearlings, attempted to nest each spring and most adult hens renested if they lost their first clutch early in incubation.

Losses of the Eastern Wild Turkey from a Stable Alabama Population Loss rates of the eastern wild turkey (Meleagris gallopavo silvestris Vieillot) from the Saugahatchee Wildlife Research Area (SRA) in central Alabama. increased with increased turkey population levels. After the expanding population stabilized, winter losses of adult and young turkeys aproximated 50 percent of the fall population. Poults captured as brood flocks in 1971, dispersed up to 6.44 km from their first summer range by the fall of 1972. Juvenile hens exhibited greater dispersal and variation in dispersal from their first summer range than did juvenile gobblers.

Influence of Season on Reproductive Characteristics of Woodchucks in Virginia Reproductive characteristics of110 woodchucks (Marmota monax) were examined between 13 March and 30 November in 1974 and 1975. Ovulation rates averaged 4.73 in adult females examined between March to June. Less than 50 percent of yearlings ovulated during this period compared to 100 percent of adults. Preimplantation loss of embryos averaged 0.5 per pregnancy. Corpora lutea persisted until August in one female but was a reliable indicator of ovulation only until July. Placental scars persisted until September in one female.

Woodcock on North Carolina Wintering Grounds During the winters of 1974-75 and 1975-76, the regional distribution patterns ofAmerican woodcock (Philohela minor) in North Carolina were determined from harvest and banding surveys. Woodcock were common transients in all regions ofNorth Carolina but were common winter residents only in the central and eastern regions. Immatures were more abundant among birds collected in coastal counties than in interior counties, and males were disproportionately common in western counties. Woodcock were numerous in the vicinity ofNew Holland, Hyde County, and 341 were banded in 17 night-lighting trips.

Hunter and Landowner Attitudes Concerning State-Leased and Fee Dove Hunting in Tennessee Five hundred and thirty-two hunters from 58 hunting areas throughout Tennessee completed questionnaires probing their views on quality dove hunting. Three types of hunting areas were examined: private areas which charged a fee; state-leased areas, no fee; and state-owned management areas which charged a fee. There was no significant difference in the criteria for determining hunt quality between types of hunting areas. Hunters' opinions were related to the number ofshells fired, the number of doves killed, and the number of hours hunted.

Feasibility of a Green-Tree Reservoir in Eastern Texas The establishment of a green-tree reservoir on private land in eastern Texas was economically successful for a timber company. The initial investment was recouped within two years from hunter fees. Hunter success averaged 1.07 and 1.51 ducks per day, respectively, for the first and second seasons. Questionnaires indicated the hunters were pleased with the project and would like to see the project continued and expanded.

Fire Ant-Muskrat Relationships in Louisiana Coastal Marshes The relationship between fire ants (Solenopsis spp.) and muskrats (Ondatra zibethicus) was investigated in Louisiana coastal marshes because of persistent reports of ant depredation on young muskrats. Two different marsh types in southwestern and southcentral Louisiana were selected for study. During May-June of 1974 and 1975, 50 muskrat houses were opened on each study area; 50 additional houses were examined during January 1976 on the western study area. There were no significant year or area differences in the proportion of houses which were active or which contained ants.
