Timing Of The Blue Crab Fisheries Of Virginia And Its Application To Harvest Management, J. Dale Shively

OES Theses and Dissertations

The timing of a fishery is a quantitative expression of the composite behaviors of harvesters, markets, animals and climatic events. A quantitative description of the timing of the blue crab (Callinectes sapidus) fisheries of Virginia was established using the time density model of Mundy (1979). Blue crab catch statistics supplied by the National Marine Fisheries Service and the Virginia Marine Resource Commission were divided into two fisheries based on gear type; the summer and winter fisheries. Average performance curves were then constructed using average cumulative proportions of catch. Annual yield estimates were also made and timing in five …

Aquaculture--Now, Factory Fish Farming, Michael W. Fox

Aquaculture Collection

"Aquaculture 1983" was the title of a 5-day symposium and industry exhibit held in Washington, D.C., on january 9- 13,1983, sponsored by World Mariculture Society, Catfish Farmers of America, Fish Culture Section of the American Fisheries Society, U.S. Trout Farmers Association, Shellfish Institute of North America, and National Shellfisheries Association. While ecologists, economists, futurologists, and others have touted the virtues and potentials of intensive fish and shellfish farm- · ing, this growing industry in the U.S. may become blighted by the same problems that have come to afflict agribusiness' "factory farming" of crops, livestock, and poultry.

The Fisheries Of Deer Creek Reservoir, Utah, With Special Emphasis On The Yellow Perch (Perca Flavescens Mitchill), Gale R. Lewellen

Theses and Dissertations

This thesis is concerned with the fisheries of Deer Creek Reservoir, Wasatch County, Utah, with special emphasis on the yellow perch. The study period was from May 13 to November 24, 1968. Objectives included the determination of size, age, and food habits of the yellow perch. Parasitic occurrences in the perch population by Ligula intestinalis were also recorded as well as the utilization of the perch by the fishermen. Observations on other species of fish including an analysis of rainbow trout stocking programs were also objectives of this thesis. Data was gathered by means of creel census and fish collection …

Eutrophication Trends Of Bear Lake, Idaho-Utah And Their Effect On The Distribution And Biological Productivity Of Zooplankton, David Nyquist

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Zooplankton of the littoral and limnetic zones of Bear Lake, Idaho-Utah, were collected over a 17-month period. Twenty-three species of zooplankton were recorded, as well as nine other species represented by both flora and fauna. At the time of sampling 17 physical and chemical parameters were also measured. Methods of analysis for the plankton and the environment are described and discussed.

The objectives of this project were fourfold:

1. To establish a record of the current zooplankton population before changes due to the increase of organic nutrients occur.
2. To compile a qualitative and quantitative standard against which future populations can be …

Shellfish Resources Of Washington, Robert Grant Levens

Graduate Student Research Papers

This paper will explore the salt water shellfish resources of Washington State. Particular emphasis will be placed upon the Pacific and Olympia Oysters, the Dungeness Crab, the research being done at Quilcene, and the lesser varieties of shellfish, including shrimp and the hardshell species of clams. The latter includes the littleneck, butter, Manila, and geoduc clams. A major emphasis will be the commercial importance of the shellfish, but the sportsman and the expanding role of Washington as a summer recreation area will not be overlooked.
