A Preliminary Report On The Use Of Hormones To Ovulate Striped Bass, Roccus Saxatilis (Walbaum) Of 162 female striped bass treated with hormones during the 1962 spawning season, 44 (27.2%) were induced to ovulate. Of several preparations used, chorionic gonadotropin proved to be very effective while follicle stimulating hormone was slightly effective. Of 36 million striped bass eggs put into the hatchery only 7.3 percent hatched. The cause of mortality is 1argely unknown.

Lake Shelby, an 829-acre natural lake, located in Baldwin County at Gulf Shores, Alabama was treated with emulsifiable rotenone in October, 1956 to eliminate an undesirable fish population. The lake was restocked with the bluegill sunfish, Lepomis macrochirus; the redear sunfish, Lepomis microlophus; and the largemouth bass, Micropterus salmoides. Subsequent population examinations following restocking revealed in 1958 that a copepod was infesting the gills of the fish.

Preliminary Investigations Of The Use Of Aqualin For Collecting Fishes Bioassays were conducted with Aqualin, a herbicide manufactured by the Shell Chemical Company, to investigate its possibilities in collecting fishes from lotic waters as well as to determine its relativity to toxicity to five species of fishes. A narrow range of toxicity was found between the largemouth bass, b1uegill, bowfin, mosquitofish, and the fathead minnow. The 24-hour TLm (median tolerance limit) values ranged from 0.062 to 0.183 ppm at 71 º F. Bowfin were the most sensitive fish tested.

A Description And Some Results Of A Florida State Wide Fish Tagging Program During the period 1960-1962 a state-wide fish tagging program employing substantial rewards to sport fishermen for tag returns was conducted in Florida. A total of 19,470 fish including 5,328 largemouth bass were captured, tagged, and released. There were 24.2 percent of the tagged bass, 4.5 percent of the bluegill, 3.8 percent of the shellcracker, and 8.9 percent of the crappie returned. Little difference in returns was noted between fish which were transported prior to release and those which were released into the waters from which they were captured.

The Status Of Diquat And Paraquat As Aquatic Herbicides The chemical and physical properties and phytocidal activity of diquat (1:1'-ethylene- 2 :2'-bipyridylium cation) and paraquat (1 :l'-dimethyl-4 :4'-bipyridylium cation) are discussed. Data are presented on the evaluation of herbicidal activity of the various salts of these 2 chemicals under controlled laboratory conditions, in plastic pools, and in earthen ponds. Research indicates that a majority of common submersed and many emergent aquatic weeds may be killed by concentrations of 0.2 to 0.5 ppm cation of these 2 chemicals.

Status Of Tilapia Nilotica Linnaeus In Florida The Florida Game and Fresh Water Fish Commission's Fishery Division obtained 3,000 Tilapia nilotica fingerlings from Auburn University on August 30, 1961. These were used as brood fish and were stocked in a 3-acre naturally fertile mined-out phosphate pit in Central Florida at the rate of 1,000 per acre. From time of stocking until May, 1962, there was an estimated 7 inches of growth. During the latter part of May this pond appeared to go into an overcrowded condition. Twelve ponds totaling 65 acres have been stocked with tilapia from the brood pond.

Two Devices For Applying Herbicides To Small Ponds Two boat-mounted machines for applying herbicides or other similar materials to small ponds are described. A dry materials spreader was assembled from three lawn-type fertilizer spreaders. Powered by a small air-cooled gasoline engine the spreader operated effectively to uniformly distribute granular herbicides, lime or similar materials. Distribution of granular material at rates ranging from 100-1,000 Ibs. per acre was possible. A boat-mounted spray rig employing a 15-foot boom eliminated the need for a two-man crew for treating small ponds with liquid materials.

The De1ury Method was used to estimate the number of channel catfish in three ponds of different years from the catch records of 20,790 anglers at the Farm Pond Project, Auburn, Alabama. The ponds were drained, and the accuracy of the estimates was determined. Estimates for each pond were made using the average number of channel catfish caught per angler per hour at intervals of: 1 day, 500 angling hours, 800 angling hours, 1,000 angling hours, and one week.

The purpose of the cooperative fishery and wildlife units, as stated by Congress, is "to facilitate cooperation between the Federal Government, colleges and universities, the States, and private organizations for cooperative unit programs of research and education relating to fish and wildlife and for other purposes." This paper describes only the fishery phase of the program which is now getting underway. The training of fishery biologists for professional employment is considered the primary objective at this stage. The conduct of research is also recognized as having high importance.

Self Contained Underwater Breathing Apparatus (Scuba) As An Aid In Fisheries Work The development of self-contained underwater breathing apparatus (SCUBA) in recent years has opened an entirely new world to those who are physically able to enjoy it. SCUBA is now used extensively in marine biology and is beginning to find its place in fresh water fisheries research and management. More aquatic biologists would probably utilize SCUBA if they were more familiar with its possibilities and its limitations.

Two farm ponds in south Florida were treated with a concentration of 0.5 part per million by weight of 1,1'-ethylene-2,2'-dipyridylium dibromide (diquat) on April 4, and May 21, 1962, to determine the effect this aquatic herbicide may have on the bottom fauna and plankton naturally existing in these two bodies of water. Bottom samples were taken from the ponds with a 6" by 6" Ekman dredge before and after treatment. The organisms were sorted from the debris and counted. Plankton samples were also taken before and after treatment to evaluate the effect of this herbicide on the plankton.

The Protein Requirement Of Channel Catfish, Ictalurus Punctatus (Rafinesque) A study was made to determine the level of dietary protein needed by channel catfish for optimum growth. The experimental work was conducted in the Farm Ponds Laboratory of Auburn University, Auburn, Alabama. Each of 40 stainless steel troughs was stocked with 25 six- to seven-inch fish. These fish were fed experimental diets at a rate of 2.5 percent of their body weight per day. Every 14 to 21 days from June 22 to September 3, 1961, the fish were re-weighed and their daily amount of food adjusted to the new weight. Eight purified diets were fed, each to five randomly-assigned troughs.

Temperature Preferences By Two Species Of Fish And The Influence Of Temperature On Fish Distribution Experiments were conducted to determine the preferred temperatures and the final preferenda of Pimephales promelas and Lepomis cyanellus. Specimens of P. promelas and L. cyanellus were acclimated to five and four different temperatures for 30 days. A gradient tank was built permitting a temperature gradient of 2° C. per chamber. Openings in the partitions between the chambers let the fish move freely throughout the tank. One fish was used to a test and ten tests for each acclimation level. Recordings of the position of each fish were made every 15 seconds for 40 minutes.

Potassium permanganate is dissolved in fish hatchery ponds and minnow hatchery ponds at the rate of from two to six parts per million to produce oxygen during acute oxygen shortage caused by excessive organic decay and to counteract hydrogen sulfide gas during seining operations. Potassium premanganate treatments are also used as prophylactic measures to prevent expected oxygen depletion. Empirical evidence indicates the efficaciousness of these treatments. A specially designated boat for the application of the chemical to the water was developed.

Pied Channel Catfish--A Color Mutation A pied or variegated six inch fingerling channel catfish, letalurus puntatus, was discovered when a pond of normal colored fingerling channel catfish was harvested in the fall of 1959 at the Joe Hogan State Fish Hatchery, Lonoke, Arkansas. This fish was saved and reared for two additional years before it was finally lost in the spring of 1962. The authors believe this to be further evidence supporting the belief held by many fish culturists that the "Arkansas Strain" of channel catfish is domesticated.

Catfish Basket Comparison Study A study was conducted which tested the orientation of the slotted opening in welded wire catfish baskets. Comparisons were made as to the catfish and gamefish catches when the slotted openings were set horizontally, vertically, or at random. Catch rates are presented in 48, 72, 96, and 120-hour set periods. Catfish (primarily white catfish) comprised 97.79 percent of the total weight, and were caught at an overall rate of 1.16 pounds per basket-day. The random, horizontal, and vertical opening baskets yielded 1.28, 1.06, and 1.15 pounds of catfish per basket-day, respectively.

Low-Flow Regulation As A Means Of Improving Stream Fishing Studies by the U. S. Study Commission, Southeast River Basins, and cooperating agencies have disclosed that utilization of many streams in the study area is curtailed in part by excessively low stages and sometimes by excessively high stages during the fishing season. The U. S. Study Commission has considered the regulation of low flows by controlled discharge from upstream storage reservoirs as one means of improving such streams for fishing.

Dynamics Of The Largemouth Bass Population In Bull Shoals Reservoir, Missouri Black bass fishing in the White River Arm of Bull Shoals Reservoir, Missouri, was regarded as sensational for several years following its impoundment in 1952. In 1958, just after a tagging program was added to test netting and creel census programs, an unpredicted decline in black bass fishing began. Only largemouth bass nine inches or longer were tagged so population estimates include only that portion of the population. In 1958, black bass numbers reached an all-time high, but late that year the population began a decline which continued throughout the study.

Harvest Of Fish From Tailwaters Of Three Large Impoundments In Missouri Quantitative creel census techniques were employed on Missouri tailwaters for the fist time during 1961. Specific areas below Table Rock and Taneycomo Reservoirs on White River and below Clearwater Reservoir on Black River were censused using a stratified sampling technique throughout the year. Estimated fishing pressure on Table Rock tailwater was 608 hours per acre and the rate of catch amounted to 0.62 fish per hour. The yield per acre was about 380 fish, weighing 192 pounds. Hatchery reared rainbow trout comprised nearly 90 percent of the yield by number.

The Effects Of Lime Treatment On Benthos Production In Georgia Farm Ponds Past research by the Georgia Game and Fish Commission on lime treatment of farm ponds has indicated a definite improvement in fertilization results following lime application. Management recommendations for problem areas has been one ton of agricultural lime per acre. This study was initiated to determine the effects of lime treatment on the qualitative and quantitative production of benthic organisms in upper coastal plain and piedmont ponds. Lime added at the rates indicated above will significantly increase production of benthic fish food organisms.

Water Quality Criteria For Freshwater Fishes Good productivity of fish and aquatic life are dependent upon clear, clean water at favorable temperatures and with sufficient concentrations of needed dissolved gases and solids. The number of individuals and species of bottom animals or plankton present in streams and lakes are important criteria of water quality. Siltation is one of the most damaging and widespread pollutants; it causes reduction of light penetration, destruction of shelter, and smothering effects on eggs.

Tolerance Of The Fry Of Common Warm-Water Fishes To Some Chemicals Employed In Fish Culture The toxicity of fifteen chemicals used in vegetation control or disease treatment was studied. The fry of largemouth black bass, Micropterus salmoides, bluegill, Lepomis macrochirus, and channel catfish, Ictalurus punctatus were used as test animals. Chemicals included were three forms of silvex, three formulations of endothal, simazine, atrazine, diquat, two forms of benzenehexachloride, roccal, acriflavine, malachite green and methylene blue. Results of toxicity tests were used to arrive at a safe concentration of the various chemicals for the species of fry used as test animals.
