An Evaluation Of Several Marks On Channel Catfish, Ictalurus Punctatus (Rafinesque) In November, 1969, four groups of channel catfish, Ictalurus punctatus (Rafinesque), with 20 fish per group were marked and put in cages in an earthen pond at the Auburn University Agricultural Experiment Station, Auburn, Alabama. Marking methods consisted of four dyes injected and applied with a tattoo machine, two fluorescent pigments and a hot and a cold brand. The fish were sampled weekly for a period of 28 weeks and each mark was evaluated on the basis of mark retention and ease of identification.

A Survey Procedure For Evaluating Stream Fisheries A survey procedure was developed for judging the relative quality of trout waters and used in surveying streams in National Forests in Georgia, Virginia and South Carolina. The purpose of the survey was to provide land managers with information that would help in making decisions affecting trout streams. The procedure incorporates water quality analysis, fish population sampling, and a comparative evaluation of habitat conditions based on a stream's present and potential capability for producing wild or "native" trout fishing.

The results from gill nest samples, a series of cove rotenone samples, and a creel census were compared to the total fish population obtained through the drainage of Lake Russell, a 90-acre reservior in Northeast Georgia. An extended period of gill netting yielded the best representation of the various fish species present in the reservoir, but gave a poor estimate of the relative abundance of the fish species. Cove rotenone samples of known acreage gave a good representation of the total weight per acre of the reservoir.

A Modified Folsom Plankton Splitter For Analysis Of Meter Net Samples The large number of meter net samples needed to determine the spawning success of various species of fish in Canton Reservoir, Oklahoma, made subsampling advantageous. The basic Folsom plankton splitter was enlarged and modified so that meter net samples with volumes up,to 4,000 m\\. could be split into IO approximately equal subsamples. The splitter was constructed from a 12 inch diameter Plexiglas2 cylinder. Construction was accomplished using common shop tools.

Vegetational Changes Associated With Water Level Stabilization In Lake Okeechobee, Florida Ecological changes in plant communities in several Florida lakes have been noted by biologists in the past, but rarely have the parameters of these communities been documented for future reference. Soil moisture is an important factor in determining which plants will occur at particular elevations, but more important is the inundation tolerance of the various species. The purpose of this study was to compare the long range effects of water level fluctuation on the marsh vegetation of Lake Okeechobee.

Food Habits Of The Carp, Cyprinus Carpio L., In Five Oklahoma Reservoirs Alimentary tracts were examined of 1010 carp collected with gill and trammel nets by commercial fishermen from four riverine reservoirs, and 211 adult and 45 young carp from Lake Carl Blackwell, a headwaters reservoir. The alimentary tract contents of carp in five Oklahoma reservoirs contained algae, plant fragments, seeds, entomostraca, chironomids, Chaoborus, pelecypoqs, caddisflies, Ceratopogonidae, animal fragments, and organic and inorganic matter. Terrestrial insects were of rare occurrence.

Food Habits Of Adult Flathead Catfish, Pylodictus Olivaris (Rafinesque), In Oklahoma Reservoirs Food items were found in 47.0% of 1329 flathead catfish stomachs collected by gill and trammel nets from six Oklahoma reservoirs: Carl Blackwell, Eufaula, Fort Gibson, Grand, Hudson, and Texoma. The average number of food items was 1.6 per stomach and the average volume per stomach was 26.4 ml in stomachs with food. Fish comprised more than 95% of total food volume and total number of food items in all six reservoirs. Gizzard shad contributed from 49.5 to 91.7% of total stomach volumes. Freshwater drum were second in importance as forage, accounting for 3.3 to 38.2% of total volumes.

Predation On Stocked Rainbow Trout By Chain Pickerel And Largemouth Bass In Lake Ouachita, Arkansas In many reservoirs predation on stocked fish has been considered as one of the major limiting factors in establishing a particular population. Following several years of water quality determinations it was found that Lake Ouachita maintained a sufficiently oxygenated hypolimnion to support trout. As a result several thousand catchable rainbow trout, Salmo gairdneri, were stocked into the lake.

Limnological data collected during a four and one-half year period at Lake Sinclair is reviewed. Comparison of temperature and oxygen profiles are made in areas of the lake receiving hot water discharge and in unaffected areas. Hot water discharge was found to increase temperature and dissolved oxygen substantially during both summer and winter. In addition, hot effluent eliminated or altered the thermocline in the affected area. These effects were evident in varying degrees for 2.3 miles below the source.

Stomachs from 285 longnose (Lepisosteus osseus) and 603 Florida gar (Lepisosteus platyrhincus) were collected from five lakes in central Florida. Ofall stomachs examined, 432 or 49 per cent contained food items. Stomach data grouped from the two species and five lakes indicated that gar in central Florida lakes feed principally on nongame forage fish and do not extensively utilize game fish species. Nongame forage fish comprised 57 per cent of the total number of food items consum~d, while only II per cent were game fish.

From 1967 through the spring of 1970 Lakes Hartwell and Clark Hill on the upper Savannah River between Georgia and South Carolina have been stocked with the striped bass Roccus saxatilis (Walbaum) X white bass, Roccus chrysops (RaFinesque) hybrids. A total of 30,000 fingerlings and 26,120,000 fry have thus far been introduced. Approximately 130 hybrids were captured during a one year period (196970) of which 87 were examined for age, growth rate, food habits and meristic characters.

Bioassays were conducted on nine chemicals using one week old larvae and one month old fingerling striped bass, Marone saxatilis (Walbaum), as the test species. The chemicals tested were potassium permanganate, potassium dichromate, copper sulfate, Dylox, ethyl and methyl parathion, Karmex, butyl ester of 2, 4-D and HTH. Tests were conducted at 70° Fahrenheit in glass containers using reconstituted water as the diluent. The fingerlings were much more tolerant to Karmex, potassium dichromate, potassium permanganate and butyl ester of 2, 4-D than were the larvae.

Some Early Life History Of Florida's Inland Striped Bass, Morone Saxatilis Striped bass, Morone saxatilis, were successfully established ih Florida's fresh water lakes during the summer of 1968. Populations are presently known in at least six separate bodies of water. Lake stocking rates have ranged from 43 fish per acre to 5 fish per acre. All stocks were obtained from Moncks Corner Striped Bass Hatchery, South Carolina, as one to four day old fry and reared to approximately 2 inches (TL) at State hatcheries prior to stocking. Growth has been rapid but variable between populations. The average first year of growth was 11.1 inches (TL).

Observations On The Striped Bass, Morone Saxatills, In Keystone Reservoir, Oklahoma The Oklahoma Department of Wildlife Conservation initiated a program to establish striped bass in Keystone Reservoir in 1965. During the period 1965 to 1969, approximately 2.75 million striped bass ranging from fry to adults have been stocked. A program to determine if a spawning population of striped bass had developed was started in March 1969. The search for natural reproduction utilized egg sampling, meter netting, shoreline shocking, and shoreline seining methods. Natural reproduction was not found in 1969.

Improved Method Of Treating Ponds With Antimycin A To Reduce Sunfish Populations A new method of using antimycin to thin overcrowded sunfish populations was tested in five ponds from 2.8 to 8.2 acres in surface area. Concentrations of 0.6 to 1.6 parts per billion of antimycin applied in the shallow upper ends of the ponds removed from 21.0 to 102.1 pounds per acre of sunfishes, but killed almost no largemouth bass of any size. The partial treatment method worked well in every pond in which it was tested despite some wide diurnal fluctuations in pH.

Dredging, Filling, And The Inalienable Public Trust — The Future Of Florida's Submerged Environment Dredging and filling, especially to create waterfront property, has hadserious adverse effects on Florida's submerged environment. Primary adverseeffects of dredging and filling are disturbance or elimination of establishedaquatic habitats. Dredging and filling peaked in Florida from the 1920'sthrough the 1950's when large tracts of submerged land were sold to attractoutsiders. Submerged lands are generally considered to be held in inalienablepublic trust and legal questions arise concerning sale of these publicly-ownedlands.

Pesticide Residues Of Twenty Mississippi Delta Lakes In 1969 the pesticide concentrations of 20 randomly selected Delta Lakes were evaluated by gas chromatograph. The DDT complex and toxaphene were the prevalent pesticides found in water, fish and bottom sediment. Lake waters were generally low in pesticide residues. Pesticide residues of DDT+metabolites and toxaphene in fish flesh ranged respectively from 0.15-10.60 p.p.m. and 0.0-20.0 p.p.m. Bottom sediment contained from 0.02-3.58 p.p.m. DDT+metabolites, while toxaphene ranged from 0.0-2.47 p.p.m. All lakes surveyed were found to contain pesticides.

Fish Production In Arkansas During 1969 As Compared To Other States Economic returns from the commercial production of fish in Arkansas during 1969 were approximately double those of 1966. Acreages devoted to the culture of golden shiners and channel catfish in Arkansas showed major increases. The cash return from shiners was up 60 percent, and that from catfish increased almost fourfold. The overall return to Arkansas from all fish culture exceeded $17 million, whereas the nationwide return from baitfishes and catfish alone was nearly $35 million.

Crawfish-Waterfowl, A Multiple Use Concept For Impounded Marshes A study was initiated in order to evaluate crawfish (Procambarus clarki) production in several impoundments managed for waterfowl on Rockefeller Refuge, Grand Chenier, Louisiana. Impoundments have been intensively managed for waterfowl on the refuge for the past 16 years, however, this has been through a gravity flow system. Pumping units were installed in three ofthe impoundments in 1968, bringing under water control some 6,000 acres of marshland.

A total of 275 channel catfish, measuring on the average of 21.4 mm in total length were raised in the laboratory for 120 days under controlled temperatures of 26,28, and 32 C with lO-hr and 14-hr photoperiods. Data on growth, f09d consumption, food conversion efficiency, and water quality were collected at IS-day intervals. Analysis of length-weight relationship showed that the experimental conditions had no effect on body shape. The fish under 28C-IOL had slow growth in length throughout the study period.

Fecundity Of Largemouth Bass, Micropterus Salmoides, Lacepede Receiving Artificial Food Fecundity of largemouth bass, Micropterus salmoides, Lac. reared and maintained on two diets was measured by use of a technique of collecting naturally-spawned eggs from nylon felt spawning mats. A volumetric measurement was made of the eggs in 10 spawns from Year Classes I, II and III pellet-fed fish for comparison with eggs from Year Class II bass fed forage fish. Average eggs per spawn for the Year Class I fish was 9,551; for Year Class II pellet-fed, 21,744; for Year Class III, 15,223 and for Year Class II fish-fed, 19,410.

A Preliminary Report On Spawning And Rearing Of Grass Carp (Ctenopharyngodon Idella) In Arkansas Previous attempts to artifically spawn the grass carp have been unsatisfactory, with complete failure or insignificant success using the Russian method des~ribed by A. G. Konradt (1965). The same basic procedure, with variations in hormone, size of dose, and number of injections, proved to be successful in our attempt to spawn four year old fish. The following significant observations were made: I. Human chorionic gonadotropin, used as stimulating injections, and dry, whole carp pituitary, used as the resolving injection, produced a high percent of viable eggs. II.

Spawning behavior, age and growth, and sport fishery for the silver redhorse, Moxosloma anisurum (Rafinesque), in the Flint River, Madison County, Alabama, were studied in 1969 and 1970. Spawning silver redhorse were first observed on April I, 1969, and April 8, 1970, at a water temperature of I 4.4° C. (58° F.) Females appeared to mature between the sixth and seventh year at a length of 548-600 mm. Males appeared to mature at 510-530 mm., but most seemed to mature at the same age. Growth of males and females was approximately the same until age group VI.

A Study Of Fish Movements From The Okefenokee Swamp Into The Suwannee River The construction of a dike dividing the Okefenokee Swamp and the Suwannee River in 1960 and the phenomenal poundage of bowfin found in the river prompted an investigation to determine what fish were entering the river by passing over the dike from the swamp. Twenty thousand nine hundred and forty-six fish weighing 18,590.3 pounds were calculated to have moved over the spillway from February 20, 1969 to June 26, 1970. Bowfin comprised seventy-nine percent by weight of the fish and yellow bullhead were the most numerous species to come over. Ninety percent of the movement occurred at night.

The dependence of commercial fishing success on strong yearclasses of striped bass is demonstrated, using four years of catch records from a small group of cooperating gill-net fishermen. Age analysis of these Rappahannock River catches during 1969 and 1970 revealed that an approximate tripling of landings in 1970 was a result of selection for the dominant 1966 year-class.

Examples of stream disturbance problems are cited. Soil Conservation Service Public Law 566, Army Corps of Engineers Section 208, and highway construction projects cause most stream damage. Significant stream fishery losses are also attributable to agricultural activities, railroad construction, urban and industrial development, and even to private self-interest groups and individuals.

The Destruction Of Our Most Valuable Wildlife Habitat The hardwood forests that grow on rich alluvial soil are our most valuable wildlife habitat. All states in the Southeastern Region and some other states were originally endowed with an abundance of this type of wildlife habitat. The soil which supported this habitat is also valuable for agriculture and this has caused the clearing of millions of acres. Shortly after World War II the rate of clearing of the bottomland hardwoods increased alarmingly. In the last ten years, the destruction of our most productive wildlife habitat has reached almost catastrophic proportions.

Forest Soils And Game Nutrition Early writings indicated that high soil fertility levels increased both quantity and quality of some wildlife species. More recent work has shown that factors other than soil fertility are also related to quality range for wildlife. Soils apparently have not been a limiting factor to turkey distribution in Missouri, since transplanted populations have done well on many soil types, even prairie soils. Weights of fawn whitetailed deer ranged from high in north Missouri to low in south Missouri, presumably reflecting a poorer quality of range in the Ozarks.

Computer Application To Drawings For Special Permits Contemporary conservationists are frequently faced with the problem of issuing special permits when there are more applicants than there are permits available. The objectives of this project were to develop a computer technique for handling the selection of eligible applicants and to test its use and effectiveness in a fully automated computer system for handling drawings for special permits. Computer programs were designed to conduct the actual selection and to analyze results. A random interval sampling technique was used for selecting eligible applicants.

Exploitation And Restoration Of Turkey In Texas The pre-Columbian population of 2 million turkey in Texas (Schorger 1966) had declined to less than 100 thousand in 1928 (Anon. 1929). Written accounts of early explorers, travelers, and hunters noted numerous flocks of turkey and equally massive slaughter for food and ornamentations. Encroachment of civilization in the mid 80's, changes in land use, and indiscriminate hunting practices caused a drastic decrease in turkey numbers between 1840 and 1880. Game laws to protect turkey were initiated in 1881 and subsequent laws imposed stringent bag limits and protected hens.

Some Characteristics Of An Expanding Turkey Population A turkey population was established near Auburn, Alabama, in 1965 by releasing 26 wild-captured birds that had been wing-tagged for individual identification. In 1967 and 1968, 76 unbanded descendants of the original stock were captured, wing-marked, banded and released at their capture points. There were also 22 recaptures. All turkeys were captured after being drugged with alpha-chloralose. Weights and some measurements of captured turkeys are presented.
