Notes On The Life History Of The Swamp Rabbit In Alabama A swamp rabbit life history study was conducted in Alabama during 1960-1967. Of 438 swamp rabbits taken by hunters on Wheeler National Waterfowl Refuge in northern Alabama during February, 205 (46 percent) were males. In a sample of 64 others collected statewide throughout the year, 29 (45.3 percent) were males. Late winter weights are presented for 322 swamp rabbits examined in north Alabama. Based on implantation sites or corpora lutea counts, the mean size of 95 first swamp rabbit litters of the season was 2.863. The mean size of 17 second litters of the year was 3.176.

Winter Food Available To The Wild Turkey In A Hardwood Forest An analysis was made of 1132.5 square feet of forest litter collected during the late winter in a bottomland hardwood forest area of the Mississippi Delta. A seed cleaner and a Trier sampler were used to separate food items from litter trash and derive a quantitative estimate. Food available to the turkey averaged 135 Ibs. per acre. Sugarberry seeds made up one-half of the entire amount. The next two most abundant items found were insect galls, 22.5 Ibs., and grape, 19.6 Ibs.

The Aoudad Sheep An Exotic Introduced In The Palo Duro Canyon Of Texas A ten-year study of the reaction and adaptability of the introduced Aoudad sheep (Ammotragus lervia) in the Palo Duro Canyon of Texas was begun in the winter of 1957-58. At that time, forty-two sheep from the McKnight Ranch, Picacho, New Mexico, were released into the halfmillion acre Palo Duro Canyon. The exotic sheep were introduced into the canyon to fill a separate ecological niche and to share the vast reaches of the canyon, noncompetitively, with native mule deer.

Preliminary Report On Methoxymol To Capture Turkeys A new hypnotic agent which is especially potent in birds was tested on free-feeding wild turkeys (Meleagris gallopavo) in Florida by oral administration on baits. One hundred thirteen were narcotized sufficiently to be captured. At the optimum dosage (4 grams of powdered drug per cup of bait) the first evidences of narcosis were noted almost immediately and some turkeys were captured within 3 minutes after beginning to feed. Narcosis wore off after 8 hours even in the more heavily drugged individuals. Mortality from overdosage was less than 3 per cent at optimum dosage levels.

Radioactive Zinc As A Feces Tag In Rabbits, Foxes, And Bobcats The radioactive isotope, 65Zn was fed and injected into rabbits, opossums, foxes, and bobcats. When injected, 65Zn was detectable in feces from these animals for over a year after injection. The radioactive zinc present in the fecal pellets is also very stable to weathering. The injection of 65Zn is an excellent technique for long-term marking of feces in censusing, home range, and migration studies. Public health dangers, although largely imaginary, seriously limit the use of this technique and are discussed.

Striped Bass Hatching And Hybridization Experiments Laboratory studies to determine the effect of striped bass egg sedimentation were conducted and a mean hatch of 35.7 percent was recorded for eggs placed on coarse sand while eggs placed on plastic had an average hatch of 36.4 percent. In comparison, the average hatch on silt-sand was 13.1 percent and 3.2 percent on silt-clay-sand substrate. None of the eggs deposited on a muck-detritus substrate hatched. Further egg studies indicated that the percent hatch improved with the period of time eggs were suspended prior to sedimentation.

Dlistribution Of The Striped Bass, Roccus Saxatills (Walbaum), In Mississippi Waters Striped bass, Roccus saxatilis (Walbaum), have been reported along the Gulf Coast from Florida to eastern Louisiana. This fish has been found in all major river systems along the Mississippi Gulf Coast from the Pascagoula River west to the Tangipahoa River. The striped bass population in the west Pascagoula River supports a small sports fishery and it is the only one that consistently yields fish from year to year. The Pascagoula fish range in size up to 32 pounds in weight.

Preliminary Observations Of The Effect Of Temperature On Striped Bass Eggs And Sac Fry Data gathered at the Weldon Striped Bass Hatchery, Weldon, North Carolina, during the years 1960-1967 indicated that the optimum spawning temperature range for striped bass in the Roanoke River was between 62" F. and 67" F. The minimum recorded temperature at which spawning has occurred was 55" F. and the maximum was 71· F. Preliminary bioassays conducted at the hatchery during the 1967 spawning season substantiated this optimum temperature range, and further revealed that at temperatures of 74" F.

During the spring of 1967, 240,000 striped bass and striped bass X white bass hybrid fry were stocked in four one-acre dirt ponds. Each pond received 30,000 striped bass and 30,000 hybrids. At the end of a 71-day period, approximately 23,187 were harvested in three ponds, 12.88 percent of ,the original number. A total kill occurred in the fourth pond one week prior to harvest. Results indicate the hybrid having faster growth and higher survival rates.

An Application Of The Virtual Population Technique To Penaeid Shrimp Commercial catch statistics for brown shrimp (Penaeus aztecus Ives) from a restricted area along the Texas coast were examined by using the virtual population technique. The sum of all catches from a single year class was used as a minimum estimate of population size at the time of recruitment. The conversion of catches from pounds to numbers also made possible maximum estimates of the exploitation rate for all periods after recruitment.

Analog Computer Techniques For Age·Growth Studies Of Fishes Analog computation and simulation involves the use of an electronic computer in which scaled voltages represent physical variables. This computer solves differential equations to simulate time related systems. Simulation of Von Bertalanffy's equation representing growth in length or weight is a simple procedure. Change of constant values enables a rapid adaptation and fit to a given set of growth data. A check on age analysis by using length-weight plots may be possible with this computer. An example of its use in analysis of striped bass growth is given.

The Development Of A Taxonomic Code And Design Of A System For The Analysis Of Biological Data The voluminous amounts of biological information collected for the Mississippi Estuarine Inventory required the development of a system for the automatrc processing of this data. The prime requirement of such a system was preparing a taxonomic code that could be easily updated and efficiently handled by EDP equipment. A modified version of the phylogenetic taxonomic structure was used to reduce the extent of the code and make optimum use of computer time. By the use of several search algorithms, computer memory requirements were substantially reduced.

Spawning Behavior And Age And Growth Of White Bass In Center Hill Reservoir, Tennessee The spawning behavior, age and growth and food habits of white bass, Roccus chrysops (Rafinesque), were studied in Center Hill Reservoir, Tennessee, from October, 1965 until March, 1967. White bass began to move toward the headwaters in late February and early March when water temperatures rose above 45° F. Spawning started in mid-March at a water temperature of 53° F. and appeared to stop if water temperature dropped below 53° F. The duration of the spawning season was one and one-half to two months. The growth rate of white bass was more rapid than in other waters.

Some Physico-Chemical And Biological Aspects Of Three Cold Tailwaters In Northern Arkansas Physico-chemical factors, plankton, benthic macroinvertebrates, and fishes occurring in cold tailwaters below Beaver, Bull Shoals, and Norfork dams in northern Arkansas, were sampled regularly from July, 1965, through December, 1966. Physico-chemical conditions were similar in the three tailwaters throughout the study. The older tailwaters below Bull Shoals and Norfork dams were more productive than the Beaver tailwater in both phytoplankton and zooplankton. The greatest number of genera of plankton occurred in the Beaver tailwater, and the Bull Shoals tailwater had the least number.

An Evaluation Of Yo-Yo Flshing In Louisiana, the yo-yo fishing method has been a controversial fishing method. The yo-yo is an automatic spring loaded device equipped with a hook and when triggered by a fish will automatically set the hook and play the fish. During this project, 9,203 yo-yos were fished. The average success was 0.161 fish per effort. Approximately 21% of the yo-yos fished were tripped but caught no fish. There was little difference between day and night fishing successes. The devices were fished most efficiently during February and March. Best depths for fishing were between three and four feet.

Heat Tolerance Of Channel Catfish lctalurus Punctatus Three lots of 6-day-old to IPh-month-old channel catfish from a common initial source but reared under different thermal conditions were utilized to investigate several heat-tolerance relationships. During the experimental period the fish were held in constant-temperature tanks and samples of fish were subjected to a range of sub-lethal and lethal temperatures in test baths. The results were studied by plotting time to death of individual fish and means of test samples on semi-log paper, probability paper in some instances, and subjecting pertinent data to statistical analysis.

Temperature Selection And Heat Resistance Of The Mosquito Fish, Gambusia Affinis The average selected temperature of a sample of Gambusia affinis previously acclimated to 20°C decreased from 28-29°C to about 27"C after the fish had lived in a temperature-gradient tank for one month. The final thermal distribution of the fish varied with sex and developmental stage. Males selected lower temperatures than did adult females. The young fish, although more scattered than the adults, occurred mostly at temperatures higher than those selected by the adults.

Rates Of Respiration Of Estuarine Fish A flowing-water respirometer was used to measure oxygen consumption of five species of estuarine fish: pinfish, Lagodon rhomboides; black sea bass, Centropristes striutus; Atlantic croaker, Micropogon undulatus; oyster toadfish, Opsanus tau; and mummichog, Fundulus heteroclitus. The relation between the amount of oxygen consumed and body size, in general, may be expressed by the formula Q = a Weightk, where a and k are constants derived from experimental data for a species. Some investigators have stated that k values do not vary significantly among species of fish.

Some Effects Of Salinity On Two Populations Of Red Swamp Crawfish, Procambarus Clarki (Girard) Salinity tolerance was compared between an inland population of red swamp crawfish, Procambarus clarki, from Baton Rouge, Louisiana, and a coastal marsh population from Grand Chenier, Louisiana. Newly hatched crawfish from each population were killed in less than one week in salinities of 15, 20 and 30 ppt. Crawfish, 30 mm in total length, withstood salinities up to 20 ppt, but died in 30 ppt in two to three days. Crawfish, 40 to 120 mm in total length, showed no significant mortality after one week in salinities up to 30 ppt.

Effects Of Sewage Effluents On Fishes In Upper Patuxent River, Maryland A survey on fish population was made in the upper Patuxent River, situated between the metropolitan centers of Washington, D. C. and Baltimore, Maryland, in the summer of 1966. This stream has received effluents of eight secondary domestic sewage treatment plants. Data obtained by two series of fish collections with a 10-foot-and-one-fourthinch mesh seine during June 17-July 14 and August 5-24 were compared with water quality data (dissolved oxygen, conductivity, and pH). The effects of sewage effluent on the fish species diversity and fish abundance in ,this stream were evaluated.

A study was conducted with blue and channel catfish to determine the effect of salinity upon distribution in a tidal bayou complex on Rockefeller Refuge, Grand Chenier, Louisiana. Stations were spaced at locations from the Gulf of Mexico to Grand Lake, a large freshwater body of water which is apparently quite productive of blue and channel catfish. Collections were made primarily with an otter trawl towed for 10-minute intervals at each sampling station. Hoop nets, wire traps, trammel nets, trot lines and rotenone were used to verify trawling results.

Use Of Antimycin As A Fish Toxicant With Emphasis On Removing Trash Fish From Catfish Ponds Antimycin was applied to five fresh-water ponds at 3, 4, or 5 ppb, and to two salt-water ponds !lit 10 ppb. Undesirable fish, including four centrarchids and one cyprinid, were eliminated from four of five freshwater ponds. Undesirable fish, including a centrarchid and a livebearer, were eliminated from both salt-water ponds. Mosquitofish, Gambusia affinis, were killed in five ponds, but were eliminated in none. Channel catfish, Ictalurus punctatu8, that were in four ponds, were not killed.

An Evaluation Of Antimycin As A Selective Bluegill Toxicant Under Varying Conditions Of pH The TLm for bluegill and redear sunfish was determined in the laboratory using standard bioassay procedure and water from two sources. A considerably larger concentration of antimycin was required to kill fish of the same size under field conditions. Probable reasons are discussed. Selective kills of bluegill and redear were attempted in the field under pH values ranging from 6.4 to 9.6. The antimycin concentration required under these various conditions is discussed. Total kills following selective kills showed size selectivity as well as species selectivity.
