Oral Drugs Used To Capture Waterfowl Between 1964 and 1968, diazepam, methohexital, methoxymol, secobarbital and tribromoethanol were administered on bait to free-feeding waterfowl of several species in Florida. Characteristics for each of five such agents include varying speed of induction, duration of anesthesia, toxicity, and other pharmacological considerations. Anesthesia was produced with several dosages of each compound, but additional tests are needed to refine dosage rates. Distasteful compounds were not readily ingested which may have biased results in a few cases.

Data On Capturing Black Bears With Alpha-Chloralose Experimental dosages of alpha-chloralose, an odorless and nearly tasteless oral anesthetic, were administered on baits to 17 wild black bears (Ursus americanus) and two captive wild bears. Nine of the 17 were sufficiently narcotized to permit handling without mechanical restraint up to 48 hours later. The other free-living bears escaped in sub-effective narcosis or if anesthetized, were not located in the field. One bear died as a result of chloralose overdosage and another succumbed from an overdose of pentabarbital sodium administered after capture.

Daily And Seasonal Activity Patterns Of Mourning Doves On The Aec Savannah River Plant The daily and seasonal variation in dove abundance along roads was studied on the AEC Savannah River Plant between May 3 and October 16, 1965. A 58-mile road census was conducted five days a week sampling all times of the day during each week. The effect of ten weather factors on daily dove counts was tested. Mourning doves were active primarily between the hours of 0530 to 0900 and 1600 to 1930. Within these periods, greatest numbers were observed from 0600 to 0700 and 1700 to 1800.

Wood Duck Production And Transplants On National Wildlife Refuges In The South Atlantic States A management investigation was initiated on Savannah National Wildlife Refuge in 1965 to determine the feasibility of producing pen-reared wood ducks, imprinted to artificial nesting structures, for use in starting new nesting colonies. To date 780 young woodies, imprinted to nest in nest boxes, have been produced, transferred, and released on six national wildlife refuges in Georgia, Florida, and South Carolina. Nesting in artificial structures had not previously occurred on three of these refuges. Pages 202-208 |

Brown shrimp (Penaeus aztecus) were marked with injections of biological stains and fluorescent pigments and released in the Swan Quarter Bay tributary of Pamlico Sound, North Carolina, to obtain population dynamics information including movement, migration, growth, and mortality. From July to September, 1967,6,163 shrimp were marked and released. Of these, 1,030 (16.7%) were returned. The average interval between release and recapture was 12 days, and the average distance traveled during this time was 3 miles. Only one shrimp was recaptured in the Atlantic Ocean.

Toxicity Of Some Chemicals To Striped Bass (Roccus Saxatilis) The toxicity of eight chemicals to one week old and one month old striped bass, Roccus saxatilis, was determined. These chemicals included malachite green, acriflavine, formaldehyde, Diquat, sodium chloride, zinc, copper, and sodium sulfate. In addition the toxicity of artificial sea water and oil field brine based on chloride content was determined for one month old striped bass. Tests were conducted in one gallon wide mouth jars containing two liters of water. Reconstituted water held at 70 degrees Farenheit was used as the diluent.

A study was made by the USDA, Soil Conservation Service in cooperation with the Georgia Game and Fish Commission and the USDA, Forest Service in the summer months of the years 1964-67. The purpose was to determine the extent of thermal pollution in the tailwater and the effect of this pollution on rainbow trout. The study was made at a single-purpose, Public Law 566 floodwater-retarding structure on Hall Creek, which is a tributary of Hightower Creek in Towns County, Georgia. The conservation pool has 4.3 surface acres and is 17.5 feet deep.

Changes In The Ichthyofauna In The Beaver Reservoir Tailwaters Collections of the fishes in the tailwaters of Beaver Reservoir were made during the spring and summer of 1968. The present study is a continuation of an investigation designed to follow the development of the ichthyofauna in the cold tailwaters below Beaver Dam, Arkansas. A total of 527 fishes representing 21 species, 12 genera, and 7 families has been identified. Eight species collected in 1968 were not reported by Brown, et al. (1967) and 7 species reported in the 1967 publication were not collected in this study.

Growth Of Blue Catfish Ictalurus Furcatus (Lesueur) In The Tombigbee River Of Alabama Length-weight data from 196 fish and spine samples from 125 fish taken August 5, 1965 were used to determine growth and age composition of blue catfish in the upper Tombigbee River in Western Alabama. Mortality rates were calculated in an effort to determine the abundance of harvestable age classes of fish. The 1964 year class was represented by one specimen and no fish of the 1965 year class were taken in the sample area. The year classes prior to 1964 were well represented in the sample.

Effects Of Antimycin On Plankton Populations And Benthic Organisms One phase of an evaluation of antimycin as a piscicide in ten ponds and lakes in the Southeast involved a study of its effect on plankton and bottom organisms. Net zooplankton in the groups Cladocera, Copepoda, Rototaria and nauplii larvae were enumerated before and after the application of 5.0 ppb antimycin. All groups were severely reduced and some disappeared following the treatment. Bottom organisms in the groups Tendipedidae, Ceratopogonidae and Culicidae were enumerated. Bottom organisms in these groups did not disappear following antimycin applications.

Growth Of Threadfin Shad In Bull Shoals Reservoir Threadfin shad. Dorosoma petenense. were first introduced into Bull Shoals Reservoir in 1961. Based on fish collected in 1966 and 1967. weighted average calculated total lengths of females at the end of each successive year of life were 66. 118. 134 and 141 millimeters. and of males 64. 118 and 123 millimeters. Growth of threadfin shad in Bull Shoals was slower than in more southern and temperate regions, but life span was longer. A strong year class in 1964 was indicated by the Presence of a relatively high number of 2-year-old fish in 1966 and 3-year-old fish in 1967.

The 1957-61 Sport Fishery In An Arkansas Water Supply Reservoir A year-round creel census was conducted on Lake Fort Smith, Arkansas from August, 1957 through December, 1961. Typically, maximal fishing pressure began in March and April and terminated in May when turbidity from heavy runoffs made the lake less desirable for fishing; substantial pressure returned in July but dwindled by October. Yearly pressure varied from 12.72 to 28.70 man-hours/acre/year; largemouth bass dominated the catch. Fishing pressure was correlated with fishing success indicating the localized nature of the fishermen using the lake.

Cooperation Among Agencies In Wildlife Planning Man's overall manipulation of land and water resources has not always been in the best interests of recreational or aesthetic values. This will bear particular emphasis where the wildlife and fisheries aspects of recreation are concerned. Governmental agencies designated to perform specific functions in land and water management have pursued their objectives with vigor and ever increasing efficiency but nevertheless with singleness of purpose.

In 1964, five sections of the Shenandoah River ranging from 9.0 miles to 15.3 miles in length (average 11.4 miles) were selected for an airplane census of fishermen. The census was conducted on a randomized schedule2 for both days of the week and time of day for the counts, with weekend days weighted because of heavier fishing pressure on those days. These data for 1964 through 1967 were used to compute the total fishing pressure in these sections.

Some Effects Of Supplemental Feeding And Controlled Fishing In Largemouth Bass-Bluegill Populations The effects of supplemental feeding and controlled fishing in sUPPlementally fed largemouth bass-bluegill populations were studied in one control pond and two treatment ponds. The ponds were stocked in March and April, 1963. One treatment and the control pond were drained in October, 1964. The objective of this phase of the study was to determine the effects of supplemental feeding on growth rate, condition index, and survival of bluegill, and on population balance and total production.

Little Tennessee River Investigation A cooperative fishery survey of the terminal 33 miles of the Little Tennessee River, a tailwater environment, was made using an unequal probability sampling creel census and limited population sampling. From June 1964 to June 1965, 29,349 anglers caught 64,714 fish at a rate of 0.75 fish per-angler-hour, or 2.2 fish per-angler-day. Of all anglers, 56% were successful, 91% lived within 40 miles of the stream, and the average expense per-trip was $2.41. The catch was 70.5% trout, 16.3% sauger, and 13.2% other species.

Mass·marking Warm Water Fish By Compressed Air And Fluorescent Pigment Marking is accomplished by embedding fluorescent pigment into the dermal tissue of fish with compressed air. The principal species evaluated were largemouth bass, Micropterus salmoides, bluegill, Lepomis macrochirus, redear sunfish, Lepomis microhophus, and channel catfish, Ictalurus punctatus. Marking rate was approximately 1500-2000 fingerling size fish per hour with a two-".,'m team. Mark detection requires ultraviolet light. Air pressure and application distance are critical factors in marking success.

Certain Advantages Of Simple Formulation In Fish Studies And Statistics The growth of fish is an important factor in the useful studies of fish populations. There are several well known methods of comparing growth of fish. Only one will be discussed in this paper. This method uses the formula W; KLn where W is weight in grams, k is a constant, L is length in millimeters, and n is a power, usually near 3. This paper will espouse a variant of the formula, equating W ; KL3. Here, the variable n becomes a constant 3, eliminating the vagaries of n; and the constant k now becomes a variable K changing with length, in order to maintain mathematical validity.

Use Of A Trawl For Sampling Freshwater Impoundments In Texas A study was undertaken to determi ne the value of a small otter trawl as a collection tool in 11 reservoirs in Northeast Texas. The collection unit consisted of four sets of 150-foot experimental gill nets, two drags with a 26-foot bag seine and two runs with a la-foot trawl. The seine and trawl collections were made both during the day and at night. Seining accounted for most of the 44 species of fish taken, while trawling produced the greatest number of specimens.

Field Observations On The Use Of Sodium Cyanide In Stream Surveys Sodium cyanide has been an effective method for sampling the stream fish populations in Eastern Tennessee. Its portability makes it a practical stream management tool. Cyanide is an excellent cold weather sampling method. Three ounces of cyanide in trout streams and 6 ounces in warmwater streams per cubic foot a second flow will sample 100 yards. In water colder than 55°F mortality of fish is not acute. Rainbow trout and various warmwater fish collected with cyanide and held in aquaria showed no deleterious effects from exposure to the chemical.

Summary Of The National Survey Of Needs For Hatchery Fish The National Survey of Needs for Hatchery Fish was a cooperative effort by the Bureau of Sport Fisheries and Wildlife and the 50 States to obtain information for estimating future nationwide requirements for hatchery fish. During 1966, data were collected on present and future: (1) amount and types of sport fish habitat; (2) amount and types of habitat stocked; (3) numbers and types of fishermen; (4) stocking requirements; and (5) hatchery fish production capabilities. Inland fishing waters amounted to nearly 82 million acres in 1965 and will increase 10 million acres by 2000.

Species Diversity Species Abundance Of Fish Populations: An Examination Of Various Methods Twenty sets of fish collection data were used to compare seven diversity indices. The data sets were chosen to represent the wide variation in habitat, ecologic condition, salinity, as well as other factors, encountered in fishery work. Cross comparisons of several index rankings were made and the dependencies of the various indices discussed. Variation of index score with number of species and with sample size was examined. Results indicate four indices may be applied to fishery work.

Food Habits Of Young Striped Bass Roccus Saxa Tills (Walbaum), In Culture Ponds Food of striped bass 10 mm. to 110 mm. standard length cultured at the State Fish Hatchery, Durant, Oklahoma was determined during the summer of 1967. Diet of fish in the 10 mm. to 30 mm. class consisted mainly of copepods, supplemented by cladocera and insects. After reaching 30 mm., bass utilized fewer copepods but more cladocera and more insects. Insects and c1adocera then formed the majority of the diet in fish from 60mm. to 100mm. Over two-thirds of the volume of planktonic crustacea eaten were Diaphanosoma sp. Other important crustacea were Diaptomus sp. and Daphnia sp.

Culture Of Penaeid Shrimp In Brackish·Water Ponds. 1966-671 Young shrimp have shown rapid growth in brackish-water ponds which had been fertilized, but to which no supplemental feed was added. In 1966, white shrimp (Penaeus setiferus) were stocked at the rate of nine shrimp per square meter of bottom in a pond that had been fertilized with chicken manure. In 1967, brown shrimp (P. a. aztecus) were stocked at a rate of 22 shrimp per square meter of bottom in one pond that was fertilized with rice husks and in another that was not fertilized.

Dylox® As A Control For Ectoparasites Of Fish Dylox® was effective against some fish parasites, ineffective against others. Although experimental results were inconsistent, a few workers report success in treating trichodinid protozoans. No success resulted from treating catfish with Ichthyophthirius. Applications of 0.25 ppm (active ingredient! successfully controlled monogenetic trematodes of Gyrodactylus, Dactylogyrus, and Cleidodiscus spp. Parasitic copepods were effectively controlled by weekly applications of 0.25 ppm except during periods of hot weather.

Preliminary Experiment On The Culture Of Blue, Channel And White Catfish In Brackish Water Ponds This paper reports on pond culture experiments conducted when fingerling blue, Ictalurus furcatus, channel, I. punctatus, and white catfish, I. catus, were stocked in nine brackish water ponds at Rockefeller Wildlife Refuge. All three freshwater species were stocked in ponds with an equal amount of acclimatization to determine survival, growth, food conversion, and to determine if freshwater catfish could be raised in brackish water ponds. In the past, fish culturist felt that catfish could not be grown in coastal ponds with salinities of over 1.5 parts per thousand.

Food Habits Of The Bigmouth Buffalo In A Simulated Fish Farming Environment Recent growth of commercial fish farming in the South Central United States has stimulated interest in the habits of fish species adaptable to fish farm environments. In 1964, the food habits of the bigmouth buffalo, Ictiobus cyprine/lus (Valenciennes), were determined in simulated fish farming ponds by comparison of available food and stomach contents. Results indicated competition with channel catfish for food occurred only when supplemental feed is introduced. In this situation channel catfish appear to be more vigorous competitors than buffalo.

Fish Production As Related To Soil Chemical Constituents Catfish production varied 40 per cent among 12 ponds in a uniformity test. Survival, spawning, and trash fish made no significant contribution to this variation. Production was directly related to the amount of certain constituents found in the pond soils, namely, exchangable calcium, electrical conductivity, magnesium content of soil - water (1 :2.5) extracts, and nitrate nitrogen.

A Comparison Of Fish Population Sampling Techniques On Lake Raymond Gary, Oklahoma Five types of fish population sampling gear were intensively fished in a 263 acre Oklahoma reservoir. The relative species compositions are compared, both between and within sampling methods and with bag seine samples taken at draining. A method using accumulative percentages for determining the length of time necessary to sample a population with specific gear to estimate species composition is described. Bated and unbaited nets had similar catch rates and species composition. Bluegill were more vulnerable to seine hauling during daylight hours than seine hauling at night.

Comparison Of Various Designs Of Wisconsin-Type Trap Nets In TVA Reservoirs Wisconsin-type trap nets were investigated to determine methods necessary to adapt this gear to TVA reservoirs, to establish the best operational procedure, and to determine the potential of this gear in an expanded commercial fishery. The study was conducted primarily in Wheeler Reservoir, Alabama. Three trap nets, modified in amount of flooring, mesh size, and floatation, were fished in combination with three lengths of lead. The lead of intermediate length was constructed of a smaller mesh size (4- instead of 5-inchl than the shorter and longer leads.

The Catch Of Wire Traps In Old Hickory Reservoir, Tennessee One by two-inch mesh wire fish traps were fished for 5,135 trap days in Old Hickory Reservoir between August 1, 1963 and June 30, 1964. Of the 2,661 fish caught, 83.2 percent were commercial fish, 16.2 percent were sport fish and 0.6 percent "other" species. Carp (Cyprinus carpio) constituted 61.6 percent of the catch. Crappie (Pomoxis sp.) made up 12.0 percent of the total catch. Deep baited sets had the highest catch rate (1.17 commercial fish per trap day) and also the highest percentage of commercial fish in the catch (98.7 percent).

Life History Aspects Of Smallmouth Buffalo And Freshwater Drum In Wheeler Reservoir, Alabama The life histories of smallmouth buffalo (lctiobus bubalus) and freshwater drum (Aplodinotus grunniensl were studied during 1966-1968 in conjunction with the evaluations of commercial fishery gear on Wheeler Reservoir. In this reservoir, smallmouth buffalo grows as fast as or faster than it does in other reservoirs. They are 5 to 6 years old and 17 to 19 inches long before they are abundant in the commercial catch. Drum growth is slower in Wheeler than in other waters; they are not important commercially until they are 7 to 8 years old and 16 to 19 inches long.
