Effects Of Exercise On Serum Lactate Dehydrogenase Activity Of Catchable-Size Hatchery Rainbow Trout, Salmo Gairdneri, Gerlad T. Klar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Effects of exercise and the relative condition of exercised fish were viii evaluated for two strains of rainbow trout. Circular tanks fitted with a paddle were used to continuously exercise the fish and a stamina tunnel was used to evaluate the condition of exercised trout. Trout were exercised continuously at one fish-length per second and one-half fish length per second. Serum LDH activity in Shephard-of-the-Hills (Missouri) rainbow trout acclimated to 10 C increased two fold during the first four days of exercise. Serum LDH activity returned to control levels by the tenth day of exercise. Serum LDH activity in Shephard-of-the-Hills …

Mechanisms Of Population Regulation In Confined Colonies Of Peromyscus Maniculatus (Wagner) And The Response To Exploitation, Donna Corn Olsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wild-trapped and laboratory-reared Peromyscus maniculatus (Wagner) were raised as confined colonies indoors with various stocking densities ranging from 0.026 to 0.100 mice per sq. ft. in pens of 40, 77, and 154 sq. ft. The animals were individually tagged and all pens were censused at weekly or semi-monthly intervals to record animals present, body weights, food consumption, and overt reproductive condition. At the termination of each experiment, all mice were necropsied and organ weights of gonads and adrenals recorded. Histological sections were made of the testes and ovaries. Half the colonies were subjected to density-independent exploitation by removal of 50% …

Trout Movements In A Small Mountain Stream, Thomas Mark Twedt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Five groups of 400 hatchery rainbow trout, (Salmo gairdneri), were stocked in a small, mountain stream at 3-week intervals from June to September, 1972. A fish trap captured any fish moving out of a 500 m study section.

Fish began moving at high levels during the first day of each stocking and continued at high rates for 5-8 days (Early Phase), after which movement decreased to low levels for 6-9 days (Late Phase). Early Phase fish moved primarily at night, possibly due to their disoriented state and high subjectivity to stream conditions. Fish moving during Late Phase did …

The Relationship Of Climatic Factors To Grazing Activities Of Cows On Winter And Spring Ranges, Benton M. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this research was to investigate the effects of climatic variations upon the daily activities of grazing cattle. The activities of individual cows on a partially seeded salt desert shrub range were observed and recorded during three grazing periods. Two of the periods were during consecutive winters and the other during the spring. Climatic variations during the second winter period were quantified and compared to changes in the daily activity patterns of the cattle.

Distinctly different daily routines of cattle activities were evident for the winter and spring seasons. In the spring, the cattle grazed, traveled, and drank …

Habitat Selection By Large Wild Ungulates And Some Aspects Of The Energy Flow In A Sub-Tropical African Savanna Woodland Ecosystem, Stanley M. Hirst

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of habitat selection by large wild ungulates was carried out on a 50 cm² area in the sub-tropical Lowveld region of eastern Transvaal province, South Africa. Estimations were made of herbaceous forage net productivity and ungulate secondary productivity on the same area.

Fourteen vegetation types, varying in composition and structure from open savanna to dense woodland, were delineated by association analysis. Structural and vegetational characteristics which were considered to influence ungulate distribution were measured within each vegetation type.

The study area supported resident populations of seven ungulate species during the wet season; drv season densities were higher …

Sensitivity Of Vertebrate Embryos To Heavy Metals As A Criterion Of Water Quality, Wesley J. Birge, John J. Just

KWRRI Research Reports

Embryonic and/or larval stages of the leopard frog (Rana pipiens), domestic fowl (Gallus domesticus) and the goldfish (Carassiua auratus) were treated with cadmium chloride, mercuric chloride, lead chloride, zinc chloride and sodium arsenite. The principal objectives were (1) to determine the sensitivity of vertebrate embryos to certain metals which are of consequence in water pollution, and (2) to ascertain the suitalility of vertebrate embryos as bioassay organisms for monitoring metallic pollutants within water resources. Vertebrate embryos are found to be highly sensitive to the toxic effects of all the metals studied. Concentrations of mercury as low as 10 ppb, with …

Environmental Improvement: A Concept For Harbor Maintenance Programs For Long Island Sound, John-Robert Curtin

Marine Affairs Theses and Major Papers

This paper suggests a comprehensive approach to maintenance dredging and maintenance dredge disposal for Connecticut in a carefully-regulated manner that will improve, rather than impair, the natural quality of the Sound. It proposes an interim measure that would allow for the continued operation of Connecticuts Commercial Harbor areas until a permanent program, together with the necessary technological advances, can be implemented to handle dredge disposal. This paper is based on data presently available on New Haven Harbor, presented in a report on the environmental quality of dredge spoils proposed to be removed from one area within New Haven Harbor known …

Animal Damage Control In South Dakota, V. Van Ballenberghe

Great Plains Wildlife Damage Control Workshop Proceedings

South Dakota, like virtually all other states, is subject to economic losses from wildlife depredations. We have been in the government sponsored, animal damage control business perhaps longer than some states - our history dates back to the time of Three-toes and the Custer Wolf. In 1973 we are still in that business, perhaps more intensively than ever before, and we regard animal damage control as one of the most pervasive and difficult to solve wildlife problems facing us.

The Missouri River bisects South Dakota into approximately equal "East River" and "West River" land areas. These differ ecologically, and to …

Coyote Denning As A Method Of Damage Control, Walden C. Lemm

Great Plains Wildlife Damage Control Workshop Proceedings

The coyote denning operation is a useful method in coyote control, both to control populations and to eliminate problem animals, but a thorough knowledge of coyote behavior prior to and during the denning season is essential for productive results.

Coyotes do not dig their own dens, but enlarge existing holes dug by other animals, often those dug by badgers. Coyote den holes are not difficult to distinguish from holes dug by smaller animals. Being long-legged animals, their den entrances are elongated vertically instead of being round like those of badgers and other short-legged animals.

An Assessment Of The Coyote Problem In The Great Plains States, Dale A. Wade

Great Plains Wildlife Damage Control Workshop Proceedings

It has now been 21 months since President Nixon's Executive Order #11643 was issued and there has been a complete annual reproductive cycle in the coyote population of the western states without any major influence by chemical controls. The use of mechanical controls, including non-lethal methods, and greater emphasis on removing only specific offending animals has been advocated during this time as a solution where coyotes prey on domestic animals. With this brief look back, what have been the results?

We do not have absolute data on coyote numbers and livestock depredations resulting from this change in coyote management programs. …

Fisheries Report No 12 - Results Of A Biological Survey Of A Proposed Wildlife Sanctuary At Dragon Rocks Near Hyden, Western Australia, N. L. Mckenzie, A. A. Burbidge, N. G. Marchant

Fisheries Research Reports

In 1972, three visits were made to an area of vacant crown lam 30 kilometres south-south~east of Hyden, Western Australia.

A preliminary survey was made in April 1972 and following this recommendations were made on the equipment and staff required for a detailed survey of the vegetation and animals.

From the 30th July to the 4th August 1972, a team from the Fauna Research Branch of the Department of Fisheries and Fauna began a detailed fauna survey.

Between the 20th August and the 25th August 1972, the fauna survey was continued am a botanist from the Western Australian Herbarium undertook …

Chronic Effect Of Low Ph On Fathead Minnow Survival, Growth And Reproduction, Donald I. Mount

United States Environmental Protection Agency: Publications

Fathead minnows (Pimephales promelas Rafinesque) were continuously exposed to reduced pH levels of 4.5, 5.2, 5.9, 6.6 and 7.5 (control) during a 13-month, one-generation test. Survival was not affected, even at the lowest pH tested. Fish behavior was abnormal, and fish were deformed at pH 4.5 and 5.2. Egg production and egg hatchability were reduced at pH 5.9 and lower, and all eggs were abnormal. A pH of 6.6 was marginal for vital life functions, but safe for continuous exposure. Free carbon dioxide, liberated by the addition of sulfuric acid to reduce the pH, may have had an unknown …

Preliminary Interpretations Of Coyote Population Mechanics With Some Management Implications, Frederick F. Knowlton

Great Plains Wildlife Damage Control Workshop Proceedings

The need for control of coyote (Canis latrans) depredations and a simultaneous demand for recognition of the aesthetic and ecologic values of the species create a conflict in resource utilization that should be resolved through more intensive management. A coyote population model is proposed from current estimates of density, reproduction, population structure, and mobility. Densities of 0.5 to 1.0 coyote per square mile are frequently suggested, with occasional estimates of 4.0 or more per square mile. Reproductive rates fluctuate as functions of the proportion of females that ovulate, the average number of ova shed, and in utero viabilities. …
