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.

A Test Of Track Counts As A Measurement Of Deer Population Size Three 160 acre deer enclosures were stocked with 2, 4, and 8 deer respectively. Track counts were made simultaneously on prepared surfaces in the enclosures. It was found that the track counts were not directly proportional to population size. Thus it appears that track counts are not a valid measurement of population size, if a linear relationship through the origin between population size and number of tracks is assumed. The track counts were able to detect that there were differences in population size, but it did not tell us the magnitude of this difference.

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.

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.

The age and rate of growth of channel and blue catfish were determined by the pectoral spine section aging technique. At the end of their first year's growth, channel catfish weighed 0.10 pound and were 4.3 inches in length (total length), and blue catfish weighed 0.12 pound and were 5.3 inches in length. At the end of ten years, channel catfish weighed 9.2 pounds and were 25.2 inches long, and blue catfish weighed 24.26 and were 33.3 inches long.

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.

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.

Preliminary X-Ray Studies Of Deer Productivity Near Crossville, Tennessee Handling techniques for x-raying trapped doe deer are described. Myothesia was used as an anaesthetic at the rate of 1.5 cc. per 5 pounds body weight. A portable x-ray machine with maximum output of 30 MA and 80 KV was used to x-ray eight dead and forty-eight live deer. Pictures were made of yearling deer (12-14 cm. width) at 0.5 second exposure time, 36-inch focal-film distance, 25 milliamps and 65 kilovolts. Machine settings were the same for older deer, except kilovoltage, which increased 2 kilovolts per cm. of deer width.

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.

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.

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 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.

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.

An electro-fishing unit developed for use on large impoundments was tested for efficiency in capturing Largemouth and Spotted Bass during the winter months for a tagging program. Experiments were conducted to determine mortality rate of fish captured under actual field conditions for the electro-fishing units described. Two body locations on Largemouth and Spotted Bass were tested for their ability to retain the Petersen Tag. Tagging mortality for one of the locations is given.

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.

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.

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.

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.

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.

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.
