Development of Pond Culture Techniques for Striped Bass Marone Saxatilis (Walbaum) The increasing demand for striped bass fingerlings has established a need for improved pond culture techniques for this species. Standard guidelines were developed from methods in use at several production hatcheries. These along with improvements after two production seasons are described.

Progress with Moronehybrids in Fresh Water A brief history of developments with Morone hybrids is given. Two of these fishes have shown potential as a supplemental sport fish for fresh water lakes and reservoirs. The original hybrid. white bass male X striped bass female. has provided substantial fisheries in the Southeast. Compared to striped bass, greater returns to sport fishermen, faster early growth. and higher survival has been documented. The threat of backcross deformities appears minimal at this time. The reciprocal hybrid, striped bass male X white bass female. was successfully cultured in 1973.

An Evaluation of Striped Bass Introductions in the Southeastern United States Striped bass have been introduced into many inland waters of the southeastern states in an effort to establish a fishery, and to provide a biological control for clupeoid fishes. The Striped Bass Committee of the Southern Division, American Fisheries Society compiled information on the success of past introductions in 1970 and again in 1973. The information collected by the Committee is used to illustrate the successes and failures of introductions of fry, fingerlings, and adult fishes.

Current And Future Considerations Concerning Striped Bass Culture and Management One million acres of water in inland reservoirs currently contain fishable populations of striped bass. Fingerling production in 1974 was in excessof 10.5 million fish and this equals the total fingerling introductions between 1965 and 1973. Major efforts are in progress in estuaries to reestablish striped bass populations and to mitigate losses of fish due to power plant operation. Improved fertilization techniques in ponds should serve to increase fingerling production in the future. The use of hybrids is slowly gaining favor, both in reservoirs and in small impoundments.

Tournament Catch of Largemouth Bass from St. Johns River, Florida A three-day fishing tournament on the 51. Johns River, Florida, in which 200 fishermen competed. yielded 1165 largemouth bass over 12 inches, and 1254 bass smaller than 12 inches. The over-aU catch rate was 0.50 bass per hour. The catch per acre of water fished was 0.03 bass. Over-all mortality estimates ranged from 22.3 to 43.8 percent; they were due primarily to epidermal bacterial and fungal infections, contracted by handling. The 3 I-day tag retention rate for largemouth bass tagged with the Floy FD-68-B anchor tag was found to be S1.1 percent for fish held in a hatchery pond.

Mortality Of Largemouth Bass for Two Tournaments Utilizing a "Don't Kill Your Catch" Program A study of two bass tournaments was undertaken on Lakes Sam Rayburn and Toledo Bend in March, 1974 to evaluate a "Don't Kill Your Catch" program initiated by the Bass Anglers Sportsmen's Society, Mortality offish held in live-wells or water tanks up to the point and just after "weigh-in" was determined. Delayed mortality was measured by taking a sample from the tournamentcaught bass and stocking them in hatchery ponds for 28 days. A treatment of Terramycin was given loa portion of these hatcheryheld fish to evaluate its use for improving survival of the fish.

Oxytetracycline, as a prophylaxis against secondary bacterial infections, was injected into 531 largemouth bass (Micropterus salmaides) which were caught during a fishing tournament on Lake Seminole, Georgia. The injected fish, along with 531 control bass, were held for observation in a 1-acre canal contiguous with the lake. After 19 days, 4.3% of the injected fish had died and 2.2% of the control fish had died. The oxytetracycline was not beneficial in reducing mortality in the released bass. J. A. Plumb, J. L. Gaines, M. Gennings

Tournament-caught largemouth bass were compared with hatchery bass to determine survival rates of bass injected or uninjected with oxytetracycline. Significant mortality rates occurred only in injected tournament-caught bass held in plastic pools. Hatchery controls, uninjected tournament bass and injected tournament bass held in hatchery ponds exhibited mortality rates similar to each other. Survival was best in hatchery ponds, but not significantly better than in pools except for injected tournament-caught bass. Donald A. Archer, Harold A. Loyacano, Jr.

A 1972 survey was taken of Texas bass clubs todetennine the number and location of organizations. their membership, club objectives, tournament regulations, fishing success and estimated harvest of bass from Texas reservoirs. Questionnaires were sent to 206 clubs, and reports were received from 170 of the groups during this study. The 170 reporting organizations collectively held 1,755 tournaments in 1972. Harvest records revealed an average catch per unit effort of 0.17 bass and/ OT O.28tb. per man-hour. Harvest from tournament lakes was, in most cases, less than 0.50 lb.

The Use of Antimycin (Fintrol) in Farm Ponds in Georgia The results from the use of antimycin A in Georgia fish ponds as a fish toxicant within the period 1968-1974 are presented in the following paper. Concentrations of antimycin at 0.4 to 0.6 parts per billion (ppb) were found to be the most desirable range for reducing populations of scalefish in attempting to improve balance and/ or to improve fishing. For controlling all sizes of scalefish in catfish ponds, concentrations of 2.0 and 4.0 ppb seemed effective. Franklin S. Ellis, Jr., Willard W. Thomaston

Thanite: A Fish Management Tool in Southlands Experiment Forest Ponds Thanite (82% isobornyl thiocyanoacetate) has been used as a fish management tool on International Paper Company's Southlands Experiment Forest since 1968. Annually, Experiment Forest personnel successfully move 2.000 to 4,000 largemouth bass (Micropterus sa/moides) with an 0.8 to I ppm (active ingredient) mixture of 80%Thanite - 20% Atlox 1045-A. Collection and survival percentages are higher when water temperatures are less than 70°F. Collected fish are placed in cans of untreated water in collection boats and later transferred to an aerated holding tank. James L. Buckner, Carroll J. Perkins

Fish Population Responses to Improved Lake Habitat Utilizing an Extreme Drawdown An extreme drawdown conducted on Lake Tohopekaliga rejuvenated littoral substrate, stimulated development of desirable aquatic plants and increased macroinvertebrate production. As a result of these beneficial changes standing crops offish in littoral areas increased from a high of 191 pounds per acre before the drawdown to 455 pounds per acre within two years after reflooding. Limnetic standing crops increased from 59 pounds per acre to 127 pounds per acre during the same period. William Wegener, Vincent Williams

Diel and Seasonal Occurrence of Immature Fishes in a Louisiana Tidal Pass A 15-month study of a natural tidal pass on the southeastern Louisiana coast revealed that the pass and adjacent inshore waters are utilized by a variety of immature fishes as immigration pathway and! or nursery. Eighty species representing 39 families were found to occur in the pass area, including young of several commercial and sport fishes. Two seasonal assemblages of immature fishes were identified, cold- and warmwater. Coldwater species were mostly immigrating young of offshore spawners, while warmwater spec'es were mostly young of inshore spawners. Dugan S. Sabins, Frank M. Truesdale

A long-haul seine was designed to sample 10,000 m2 of open water less than 3.5 m deep for both pelagic and semi-demersal fish populations. The net, 354 m long constructed of 20 and 25 mm bar mesh. was used to encircle the area, and by a simple method to concentrate and purse the catch in open water. Atlantic menhaden, Brevoortia tyrannus; Atlantic thread herring, Opisthonema oglinum; pinfish, Lagodon rhomboides; and striped mullet, MugU cephalus were the most abundant species collected from 60 samples taken during 1973 in the Newport River estuary (Carteret County, North Carolina).

Effect of Two Feeding Rates on Production of Advanced Fingerling Striped Bass An investigation of the effect of two feeding rates on pond production of advanced fingerling striped bass was studied at the Auburn University Fisheries Research Unit from June 27 to November 24,1972. The mean survival for fingerlings fed a high feeding rate was 71.87% as opposed to 70.13% for fingerlings fed a low feeding rate. Mean production for fingerlings fed a high and low feeding rate was 266.44 kg/ha and 293.68 kg/ha. respectively. Food conversion for fingerlings fed a high feeding rate was 3.74 as compared to 2.51 for fingerlings fed a low feeding rate.

Winter Feeding of Channel Catfish On November 24, 1973. pound-size channel catfish, which had previously been fed intensively for 6 months, were weighed and measured and placed back into nine 1/10-acre earthen ponds at the rate of 2,000 per acre. The fish were managed through the winter until the following March 4 on one of three feeding regimes; no feeding; feeding 1% of fish weight on alternate days; and feeding 1% offish weight only on "warm" days or when water temperature at a 3-foot depth was above 54 F. Fish not fed lost 99V of their weight during the I00-day over-winter period. Pages 208-216 |

Channel catfish were stocked in 27, 1/10-acre ponds at the rate of 3,000 per acre and fed nine commercial-type rations containing three protein percentages and three levels of fish meal for 200 days. Average survival for the experiment was 96.8% and 93% of the fish were over 12 inches in length at harvest. Average yield for treatments ranged from 2,330 to 3,030 Ib/acre and the average for all treatments was 2,638 lb. The results indicated that satisfactory production can be obtained with all-plant rations. The 29%. R. T. Lovell, E. E. Prather, J. Tres-Dick, L. Chhorn

Pupae of Face Fly as Food for Channel Catfish Pupae of face fly (Musca autumnalis De Geer) were offered to channel catfish flngerlings fed outdoors in plastic pools. Other channel catfish fingerlings received rations of equal parts of face fly pupae and Purina Catfish Cage Chow (pellets) or pellets only. After 9 weeks of feeding, catfish from each pool were counted and weighed. Survival rates were 94. 97. and 93% and ratios of dry weight of food to increase in live weight of fish were 1.62, 1.77. and 2.29 for fish receiving pupae, pupae and pellets mixed, and pellets only, respectively.

Comparisons of Albino and Normal Channel Catfish Grown in Cages in a Pond Albino and Donnal channel catfish, lctalurus puncta/us (Rafinesque), were stocked in suspended cages in a pond at densities of 11.1, 13.9 and 16.7 fish per ft3, respectively, with two replications of each. There wefe no apparent growth or sucvival differences between the albino and normal channel catfish. Mean gain/fash and mean gain/cage/day were significantly different (P 0.01) between the two higher stocking densities with both types of fish. These data indicate that a standing crop of about 15 Ib per ft of cage is the maximum which can be grown in still water ponds.

Macrophyte Control by Grass Carp in Catfish Ponds Macrophyte standing crop (primarily Eleocharis and Utricularia) was reduced nearly 90% in two catfish ponds after introduction of grass carp (Ctenopharyngodon idella). Abundant vegetation remained in 1-m2 exclosures placed in the ponds as controls. The stocking ratio of grass carp (live weight) to macrophyte standing crop (dry weight) that resulted in vegetation control within 1 year was 0.15 in the pond is which the fish were fed pelleted food and 0.06 in the pond in which the flsh were not fed.

Fifty male and 106 female largemouth bass were injected with human chorionic gonadotropin (HCG) during the 1972 and 1973 spawning seasons. Milt production was increased or maintained in 80% of the males tested. and 63% of the females ovulated. Females with spent or immature gonads did not noticeably respond to HeG injections. Females tested during the latter half of both spawning seasons demonstrated lower percentages of successful ovulations and reduced numbers of eggs per ovulation. Robert L. Wi/bur, Freddy Langford

Food Habits, Growth, and Catchability of Grass Carp in the Absence of Aquatic Vegetation Grass carp (Clenopharyngodon idel/a) were stocked into a 3.6-ha Georgia pond devoid of vegetation to simulate conditions that might occurr in a pond where grass carp have eliminated the macrophytes. The flSh were readily captured by hook-and-line fishing. The stomachs of 417 grass carp contained primarily terrestrial macrophytes; no fish or fish eggs were found. Many of the grass carp examined weighed less than when they were stocked. James W. Terrell, Alfred C. Fox

Life History of Warmouth in the Suwannee River and Okefenokee Swamp, Georgia Life history data were collected from Suwannee River and Okefenokee Swamp warmouth (Lepomis gulosus) from 19 July 1968 through 28 June 1973. Suwannee River warmouth became sexually mature in the third year of life. while warmouth from the Okefenokee Swamp became sexually mature in the second year of life. Collection of fecund warmouth suggested that the nesting season extended from April to late July or early August and that peak spawning generally occurred in early May. Fecundity estimates varied from 3,029 to 22,850 ova per female and generally increased with fish length. Jerome F. Germann, Lawrence E. McSwain, Daniel R. Holder, Clayton D. Swanson

Life History of the Redbreast Sunfish in the Satilla River, Georgia Life history data were collected from redbreast sunfish. Lepomis Quritus (Linnaeus). in the Satilla River between 1 July 1970 and 30 June 1973, Spawning was observed in the Little Satilla River during May and June at water temperatures from 22.2°-24.4°C. Strong site preference was evident. Nests were associated with fallen trees, stumps. or logs. The average nest diameter was 93.5 em and the preferred substrate was sand. Sex ratio was I male to 1.49 females. Fecundity estimates ranged from 322 to 9206 ova per female around a mean of 3302 ova. Jack T. Sandow, Jr., Daniel R. Holder, Lawrence E. McSwain

Ecological Aspects of the Redbreast Sunfish, Lepomis Auritus, in Florida An important element of the ichthyofauna of warmwater streams of the southeastern United States, the redbreast sunfish is the dominant species of the lower Suwannee and lower Santa Fe Rivers in Florida. Insects formed the bulk of the diet of both populations though opportunistic feeding is suggested by the wide variety of organisms tak.en. Spawning occurs from April through October, with a peak in late spring and summer. Fecundity ranged from 942 to 9968 ova per fish. Mean condition factor (K) was higher for Santa Fe redbreasts than for Suwannee specimens. D. Gray Bass, Jr., Vinard G. Hitt

Some Relationships Between Food Habits and Growth of Largemouth Bass in Lake Blackshear, Georgia The food habits and growth of 1,062 largemouth bass. Microplerus salmoides (Lacepede), collected from Lake Blackshear during the period 31 March 1970-19 December 1972 were examined. Mean lengths of bass at Age I, II, III, IV, and V were 106, 253, 350, 418, and 473 mm total length, respectively. Young-od-year and yearling bass showed great variation in growth rates. Threadfin shad, Dorosoma petenense (Gunther). and gizzard shad. Dorosoma cepedianum (leSueur). were identified as the most important forage species to bass beginning their piscivorous feeding habits.

Effects of Effluents from Trout Hatcheries on the Benthos and Fish in Receiving Streams This study evaluated the effects of discharges from three southeastern trout hatcheries on the benthic organisms and fish in the receiving streams. The U. S. Fish and Wildlife Service hatcheries were at Suches, Georgia; Walhalla, South Carolina; and Brevard, North Carolina. Although effects differed somewhat for each hatchery, the numbers and kinds of both benthos and fish generally increased immediately downstream from the hatchery outfalls. Pollution intolerant benthic organisms were not lost from the fauna below the hatchery outfalls. Kim W. Primmer, James P. Clugston

Review of Coldwater Fish Management in Tailwaters A trend in the stocking procedure of trout in tailwaters has developed as an outcome of increasing fishing pressure. Fingerling stocking of trout was initially recommended in tailwaters where an adequate food supply was available. and predation by predatory fish was not considered a problem. Eventually, fishing pressure increased and the fingerling trout were harvested before reaching a desirable size necessary to maintain a quality put-grow-and-take fishery. Consequently. stocking of larger catchablesize trout was resorted to; this procedure resulted in a quality put-and-take fishery.

Mean depth of capture of the white crappie in horizontal, bottom set gill nets in Arbuckle Reservoir in 1973 was not statistically different from that in this reservoir in 1974, or from that in Eufaula Reservoir (determined by collection in vertical gill nets) in 1968. The white crappie depth distribution was generally similar in these two reservoirs, and there was a seasonal cycle of distribution related primarily to changes in temperature and dissolved oxygen.

Managing Trends in Angler Consumption in Freshwater Recreational Fisheries A basic activity of freshwater recreational fisheries management agencies is forecasting societal demand for fisheries resources and producing the necessary supply. Today, potential consumption often exceeds the supply of fisheries of the desired quality. A primary means for enhancing contemporary fisheries management may be to regulate angler consumption. Operations research techniques are well suited for handling the complexities involved with planning multiple action policies for regulating angler consumption. Richard D. Clark, Jr., Robert T. Lackey

Barbour County Public Fishing Lake (75 acres) was stocked with approximately 500 channel catfish per acre in combination with the normal stocking rates of largemouth bass, bluegill, and redear sunfish. The lake was supplementally fed on one side only, in addition to receiving a regular fertilization program. At the end of one year of fishing, 305.5 fishermen per acre had harvested 621.8 pounds of fish per acre. Of this total, bluegill comprised 381 pounds per acre. There was no stgnificant difference between the weights of bluegill collected from the fed and non-fed areas. Merril L. Nail, Douglas H. Powell

Golden shiner fry (0.18-0.21 g) were raised in 6O-gallon tanks for a period of six months under constant temperature and photoperiod but varying stocking densities and protein levels in food. The stocking densities and protein levels were 20, 28, and 36 fish per tank, and 28, 33, and 38% protein. All the fish were fed at 5% of body weight. Growth in weight and production were evaJuated in relation to stocking densities and protein levels. It was found that a density of 20 fish/60 gallons (100,000 fry per acre) and feed containing 33% protein were desirable for raising golden shiner. Ralph B. Roseberg, Raj V. Kilambi

The sheepshead minnow (Cyprinodon variegatus). an estuarine fish of the Atlantic and Gulf Coasts, is suitable for both partial chronic and chronic (egg-lo-egg) bioassays. The fish is easily held at high population densities in the laboratory and. at about 30 C, produces numerous eggs. The average 3o-day survival of the fish from fertile egg to fry is 75%. Generation time for this species is short (3-4 months) and its small adult size (male average standard Iength=48mm) provides for relatively inexpensive bioassays. Steven C. Schimmel, David J. Hansen

Status of Faunal Recovery in the North Fork Holston River, Tennessee and Virginia Two years after pollution abatement, faunal communities in the North Fork Holston River below Saltville, Virginia. remain in a perturbed condition. The num ber of fish species is increasing at the lower downstream stations, but show little change immediately downstream of Saltville. Two species which occur regularly above Saltville were not taken at any downstream station during this study. The abundance and diversity of aquatic insects at downstream stations are extremely variable. but are generally less below Saltville than they are upstream. Donley M. Hill, Eric A. Taylor, Charles F.

Review and Discussion of Biological Investigations in The Lower Mississippi and Atchafalaya Rivers Biological studies in the main channels of the lower Mississippi and Atchafalaya Rivers below Cairo. Illinois. were summarized and reviewed with regard to their scope, methodology. and salient findings. The study area has received much less attention than the reach above Cairo, but 67 references were found to contain at least some direct mention of lower Mississippi/Atchafalaya River biota. Fishes are the best-known and most extensively studied organisms. although few intensive, standardized studies were found.

Establishment of a Resident Breeding Flock of Canada Geese in Louisiana) Canada Geese were released on Rockefeller Refuge in Louisiana in 1960 in hopes of establishing a resident, non-migratory flock. One nest was constructed in 1961; however, the Dumber of nests increased each year and by 1973, 265 nests were located on the refuge. The geese became acclimated to the warmer southern temperatures and adjusted their nesting season accordingly. They tended to nest earlier in the year with succeeding nesting seasons. The earliest nesting date on the refuge was February 19, 1968. Parent geese were allowed to incubate the majority of the nests; however. Robert H. Chabreck, Howard H. Dupuie, Donald J. Belsom

A total of 276 attempts was made to immobilize white-tailed deer (Odocoileus virginianus) using succinylcholine chloride (SC). SC was injected in powder form by dart in 256 deer (mostly free-ranging) and in solution in 20 deer (all captive). Details of dose levels, age, sex, bodyweight, whether immobilized, time interval injection to immobilization and survival rates were recorded. For the SC solution injected animals, packed cell volumes (PCV) were recorded prior to and at several intervals after injection. J. A. Wesson, III P. F. Scanlon, R. E. Mirarchi
