Potential Use Of Hydroelectric Facilities For Manipulating The Fertility Of Lake Mead, Larry J. Paulson, John R. Baker, James E. Deacon

Publications (WR)

Analysis of historical nutrient data for Lake Mead indicates that the fertility of the reservoir has decreased which may be the cause for a corresponding decline in the largemouth bass population. However, it appears that fertility can be manipulated by altering the operation of the dam. The depletion of nutrients in the euphotic zone by phytoplankton and subsequent accumulation in the hypolimnion during summer and fall provide a natural nutrient gradient from which water of varying fertility can be drawn for discharge. This combined with alterations in the depth or seasonal pattern of discharge can possibly be used to enhance …

Development Of Pelagic Larvae And Postlarva Of Squilla Empusa (Crustacea, Stomatopoda), With An Assessment Of Larval Characters Within The Squillidae, Steven G. Morgan, Anthony J. Provenzano Jr.

OES Faculty Publications

Larvae of the predatory crustacean Squilla empusa were collected from the plankton in Chesapeake Bay and reared in the laboratory to permit description of the pelagic stages before the postlarval stage.

Characters such as rostral length and spinulation, carapace spinulation, relative size of telson, overall body size, and appearance probably are of more value for specific than for generic identification. The presence or absence of teeth on the dactylus of the second maxilliped, the presence or absence of a spine on the basis of the second maxilliped, and the number of epipods may be useful characters in determining generic alliances …

Seasonal Abundance & Diversity Of Fishes At Three Stations On The Middle Fork Of Drake's Creek, Warren & Allen Counties, Kentucky, David Bell

Masters Theses & Specialist Projects

A total of 7,485 fish, representing 49 species, 25 genera, and 11 families, were electroshocked from three stations on the Middle Fork of Drake's Creek during the period January, 1972 through January, 1973. Community structure was influenced by seasonal changes in both numbers of species and numbers of individuals. The number of species per collection was at its highest, at all stations, during the month of September. The total number of species and individuals collected at each station progressively increased toward the upstream areas. Eleven of the forty-nine species collected during the course of the study provided 91.8% of the …

Petroleum Hydrocarbons From Effluents: Detection In Marine Environment, John T. Tanacredi Ph.D.

Faculty Works: CERCOM

The marine environment has become the primary disposa ground for an increasing quantity of petroleum wastes. Mushrooming demands for petroleum products and the lack of economic incentive to recycle waste oil will increase the concentrations of detrimental petroleum hydrocarbons in the marine environment

Although a continuous, low-level discharge of waste petroleum hydrocarbons into the marine environment may not be as dramatic as a major oil spill, the consequences could be more devastating over an extended period. As noted by Blumer, earlier interpretations of the environmental effects of oil must not be reevaluated in the light of recent evidence of its …

Transmission Reconnaissance Study : Dickey-Lincoln School Lakes Project, United States Department Of Interior

Dickey-Lincoln School Lakes Project

Two dams are proposed on the St. John River in northern Maine: Dickey, a high earth filled dam immediately above the confluence of the Allagash with the St. John, will have an installed generating capacity of 760 MW; and Lincoln School Dam, 11 miles downstream, a capacity of 70 MW. These dams are scheduled for completion during the mid 1980's. The U.S. Corps of Engineers, New England Division, has been allocated funds to design the project and prepare their own environmental impact statement. This report (Transmission Reconnaissance Studies) discusses alternative transmission facilities needed to connect the project with the New …

The Chromosome Constitutions Of A Hybrid Salmonid And Its Parental Types: Salmo Gairdneri And Salmo Clarki, Peter Bruce Valentine Jacky

Dissertations and Theses

A study was undertaken to investigate the application of tissue culture and histochemical banding techniques normally used in mammalian studies to fish cells and to examine the mechanisms of chromosome evolution and speciation in salmonids by comparing the chromosomes of the hybrid to those of the parental types. The application of banding techniques was generally unsuccessful in revealing bands, though quinacrine staining did reveal the presence of two fluorescent spots in the vicinity of the centromere. These were thought to be heterochromatic blocks, possibly related to the high incidence of centric fusion or fission in salmonids. Results of chromosome analysis …

A Conceptual Draft Of A Dynamic Hydro-Biological Model For Lake Mead, L. G. Everett, Bureau Of Reclamation

Publications (WR)

Food and energy transformation in an aquatic system must be understood in order to develop a simulation approach. This report provides a comprehensive study of an aquatic ecosystem. The objectives of this report are to show:

(1) the biological relationships in an aquatic system

(2) the role of nutrients in the biological cycle

(3) the role of abiotic factors in a limnetic environment

(4) the status of the art of "Eutrophication modeling".

Effects Of Starvation And Time At Stocking On Survival Of Stocked Rainbow Trout, Salmo Gairdneri, Marlin John Bricker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations of effects of starvation and time at stocking on the survival of catchable rainbow trout in two areas of Mammoth Creek in Dixie National Forest, Utah, were conducted from May 24 to December 6, 1969. Fish were starved for 6 days and 1 day and stocked in the morning (5:40-7:00 a.m.) and in the afternoon (1:45-5:30 p.m.). Out of 7,000 tagged fish stocked, 4,751 tags were returned by fishermen. The 6-day starved fish, stocked in the morning returned to the creel in highest numbers (1,240); followed by 1-day starved, afternoon-stocked fish (1,194); 6-day starved, afternoon-stocked fish (1,163); and 1-day …

Reproductive Biology Of Thais Emarginata (Deshayes, 1839) And Thais Canaliculata (Dulcos, 1832), Roy Seamands Houston

University of the Pacific Theses and Dissertations

Thais emarginata (Deshayes, 1839) and Thais canaliculata (Dulcos, 1832), are two common Pacific coast gastropods (Family: Muricidae). T. emarginata is found in semi-protected rocky areas from Alaska to Baja California, while T. canaliaulata occurs in quiet bays from Alaska to Monterey Bay, California (Ricketts and Calvin, 1966). Both species occur on rocks and jetties where they can be seen feeding upon barnacles and young mussels. Despite the abundance of these species their reproductive biology has not been examined.

In the present study, the following aspects of the reproductive biology of T. emarginata and T. canalieulata are presented: Relationship of gonadal …

Factors Affecting The Waterfowl Hunter Utilization And The Waterfowl Kill At The Bear River Migratory Bird Refuge, 1960-61, Stephen V. Goddard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1960 there were 1,955, 000 waterfowl hunters in the United States. These hunters spent $89,431, 000 (an average of $45.74 per individual) and 15,158, 000 hunter days in the field. The hunting population will increase 35 percent by 1975 (Anonymous, 1960).

The large increase in hunters will bring a proportional increase in the demand for places to hunt. Many states face the problem of providing enough public hunting for such an army of sportsmen. Studies by Kozlik (1958) in California, Gordinier (1957) and Friley (1959) in Michigan, and Bednarik (1957, 1961) in Ohio point out some of the problems …

Relationship Of Certain Environmental Factors To Benthic Fish Densities In Bear Lake, Idaho-Utah, Thomas J. Hassler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The project was initiated in June of 1958 and financed by the National Science Foundation and the Wildlife Management Department of Utah State University.

The broad aspects of the study were to determine if a relationship exists between certain physical and biological factors and benthic fish densities. The project vas divided into two parts: (l) to determine the time and extent of thermal stratification, zooplankton densities, conductivity changes within the lake and conductivity differences between the lake and its tributaries; (2) to determine it a relationship exist between benthic fish densities, temperatures, depths, conductivities and benthic zooplankton densities. The data …

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.

Studies On A Cave Fish Of Uncertain Classification, Jennie Miller Orr

Masters Theses & Specialist Projects

The specimens studied during this investigation were taken incidentally during a general faunal survey of certain peculiar streams flowing from underground channels. On casual examination it was evident that they belonged to the cave fish group but were not the well known almost colorless blind variety. After checking the descriptions in various vertebrate manuals it appeared that they were probably a new species.

There are three groups of cave fishes, the non-blind, the semi-blind and the blind. Chologaster, or the Rice Field Minnows of South Carolina, are members of the non-blind group. Forbesichthys of southern Illinois and Kentucky is an …

A Study Of The Tolerance Of Certain Species Of Fishes For Low Dissolved Oxygen & Increased Carbon Dioxide Concentrations, Charles Allen

Masters Theses & Specialist Projects

Extensive investigations have been made of the oxygen end carbon dioxide content of water in which fishes live. A review of the literature, however, shows that these studies have not been made under controlled laboratory conditions dealing with the species studied in this investigation. It was the purpose of this study to determine the lowest concentration of dissolved oxygen that will support certain species of fishes and, also, the lethal effects resulting from increased carbon dioxide tension as determined under carefully controlled laboratory conditions.
