Production Of Waterfowl In The Rain Basin Area Of South Central Nebraska, Ray Linder

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

One important form of wetlands habitat in Nebraska is the “Fresh-water Basins”; their importance extends to both waterfowl and upland game. The fresh-water basins are located primarily in south-central Nebraska. They are closed drainages, usually from one to 40 acres but ranging up to 1,000 acres, formed in the gently rolling loess plains. Soils are silt loam and the somewhat impervious soils in flat or depressed position receive and retain the largest amounts of water. This caused leaching and concentration of clay in the subsoil forming a soil type peculiar to these areas known as "Scott silt-loam," a heavy clay-loam …

Lethal Concentrations And Detoxification Time Of Toxaphene For Goldfish, Gambusia And Rainbow Trout, Gar W. Workman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the past few years the Utah Fish and Game Department, as well as the fish and game departments of other states, has been spending fisheries money for fish eradication on both lakes and streams. The Utah Fish and Game Department recently suggested to the University that research be initiated on the subject of toxaphene as a fish poison. Consequently, a better insight into conditions that exist for a given water type could be developed.

Wildlife Utilization Of Stock Ponds In Minnehaha County, South Dakota, James D. Swanson

Electronic Theses and Dissertations

Introduction: Man’s agricultural activities in South Dakota have greatly altered environmental conditions for nearly all forms of wildlife. Draining and ditching in eastern South Dakota have decreased the acreage of wetlands available to waterfowl and furbearers. Results of conversation practices carried out under the Agricultural Conservation Program as reported by the U. S. Department of Agriculture (1) show that between 1936 and 1937 South Dakota farmers had drained 760,198 acres. Drainage of wetland areas changed once valuable wildlife habitat into drylands which are of little value to waterfowl and furbearers. Waterfowl breeding grounds have been so greatly reduced that few …

Analysis Of Summer Spotlighting For Determining Deer Populations Indices, Donald C. Duerre

Electronic Theses and Dissertations

Man changes his environment to suit his needs. In doing so he has destroyed forests, plowed the land, and built cities. Deer have adopted themselves to these changes, and in many instances populations have erupted as a result. Their ability to survive advancement of civilization and increasing hunting pressure has made deer the most important big-game animal in America, The importance of deer as a game animal has caused game agencies to institute more intensive management programs. Proper management of this species has long been a problem of game technicians. In order to obtain an optimum annual harvest, the technician …

The 1957 collections were fairy shrimps of the species Chirocephalopsis bundyi while those of 1958 were tadpole shrimps', Lepidurus couesi. The presence of L. couesi establishes a new state record for this …

The Results Of Four Years Of Fish Eradication Work With Toxaphene In Nebraska, D. B. Mccarraher, Jack L. Dean

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Experimental use of the compound, toxaphene, (chlorinated camphene), as a fish eradicant was first tried in Nebraska during 1956.

During the period from 1956 to 1958 a total of 3,810 acres of water have been treated with emulsifiable toxaphene to remove rough fish populations. Concentration levels ranged from 0.05 p.p.m., to 0.61 p.p.m. The maximum depth of the nine renovated sandhill lakes was seven feet with an average depth of only 4.5 feet. Numerous spring seeps are found in all lakes and bottom deposits were organic muck and sand. The lakes are considered moderately alkaline in the 8.5 - 9.5 …

Nesting Of Mourning Doves In Eastern South Dakota, Lloyd E. Oldenburg

Electronic Theses and Dissertations

The mourning dove¹, not presently a game bird in South Dakota, is gaining support toward that status. During the 1959 state legislative season a bill sponsored by the Department of Game, Fish and Parks to place the mourning dove on the game bird list was passed by the House and defeated by the Senate. In a special dove issue of Outdoor California, January 1959, W.K. Kiel (9) stated there are currently 30 states which allow dove hunting. No state bordering South Dakota has an open dove season. However, in a special memorandum of March 7, 1958, the Nebraska Game, Forestation …

The Glory Trail: The Great American Migration And Its Impact On Natural Resources, Ernest Swift

Other Publications in Wildlife Management

Surprisingly few Americans have any definitive or comprehensive knowledge of the history of their country, although many are under the delusion that their school book history taught them all they needed to know.

They were indoctrinated with a smattering of dates which included the voyage of Columbus and the landing of the pilgrims at Plymouth. They learned what Priscilla said to John Alden, gloated over the Boston Tea Party and memorized part of Patrick Henry's speech; they were briefed on Bunker Hill, Washington crossing the Delaware and the Surrender of Cornwallis. And that just about completed that era.

Age And Growth Determination Of The Black Bullhead From Soft Fin Rays, James W. Sprague

Electronic Theses and Dissertations

Introduction: Knowledge of the age of individuals comprising populations of fish is essential to the fishery biologist. From such information he is able to calculate the rate of growth, determine the age at which sexual maturity is attained and the longevity of the species. These calculations and determinations can be applied in the management of populations and in setting fishery regulations. There are numerous methods being used to determine the age of an individual fish. Of these, the scale method is the most important means of age determination being utilized with species of fish possessing scales (Cooper, 1951). This method …

Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson

Nebraska Game and Parks Commission: Publications

The purpose of this booklet is to provide a ready field reference for identification, sexing and aging of common game species. It has purposely been kept in simplified form, presenting only those techniques which can commonly be applied in the field and avoiding those which would require special equipment and skills. Untrained personnel should be given demonstrations of the techniques, and thereafter this reference should serve as a reminder. It is not expected that the reference could successfully be used without such demonstration. Certain of the techniques such as cloaca! examination of waterfowl may require considerable practice by the individual. …

Industrial Wastes: Bio-Assays For Control Of Industrial Effluents, Croswell Henderson, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

Waste effluents from many industries are toxic to fish and other aquatic life. The control or treatment of these wastes for safe release into receiving waters presents a problem of consider able magnitude.

Much effort has been expended by some industries to solve this problem, primarily through chemical analysis for possible toxic components and then generally by a search of the literature to find out how toxic a particular component may be. Unfortunately, this approach has not been successful, nor can it be expected to be productive of satisfactory answers.
