Coprecipitation Of Phosphorus With Calcium Carbonate In Bear Lake, Utah - Idaho, Paul W. Birdsey Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Monitoring of Bear Lake was conducted in 1981 and 1982 to describe the current limnology and trophic state of the lake. The nutrient loadings of various parameters were measured from April, 1981 through June, 1982. The rate of coprecipitation of phosphorus was determined for different initial phosphorus concentrations by use of non-algal assays. Algal bioassays with Selenastrum capricornutum were used to determine the reduction in potential algal biomass as a result of the coprecipitation of phosphorus.

The lake exhibited chemical characteristics indicative of mesotrophy or eutrophy. Total phosphorus values averaged 11μg/1 for 1981 and 20 μg/1 for 1982. A hypolimnetic …

Recent Studies In The United States On Parasites And Pathogens Of Marine Mollusks, With Emphasis On Diseases Of The American Oyster, Crassostrea Virginica Gmelin, William J. Hargis Jr.

VIMS Books and Book Chapters

Morphological, systematic, faunal, and life cycle studies predominated research on marine parasites and pathogens in the United States before World War II. Much was primarily basic or academic in nature. Since then it has grown and diversified under pressure or efforts to: I) Increase yields or invertebrate-based fisheries, In nature and under controlled conditions; and 2) understand , protect, and improve the resources, estuarine and marine environments, and human health and welfare. Over the last 30 yr pathobiologlcal investigations of economically and ecologically important marine Invertebrates have broadened into submlcroscopcal anatomy (TEM and SEM technlques), physiology, Immunology, genetics, host-parasite ecology, …

U.S./Japanese Fishery Relations: Reflections On The Past And The Unsettled Future, Matthew Axel

Theses and Major Papers

U.S.-Japan fisheries history spans over a half-century of controversy. A variety of developments have taken place over this period from past to present illustrating this point. This paper will present this subject in three parts, corresponding to the historical developments that have taken place. The saga begins with U.S. post-World War II aid in rebuilding the Japanese tuna, whaling and salmon fleets. Round two examines the rapid expansion of the Japanese utilization of Alaska pollock and the development of the surimi trawlers in the early 1960s. Finally, round three, which will encompass the majority of the subject matter discussed, begins …

The Trinidad And Tobago/Venezuela Fishing Agreement, Zaleena K. Chin-Yuen-Kee

Theses and Major Papers

The twin-island Republic of Trinidad and Tobago is situated adjacent to the Republic Of Venezuela such that at one point Trinidad is merely seven miles off the northeast coast of Venezuela. Fishing activities of nationals of each country in the waters of the other are therefore common and often lead to conflict. In an attempt to solve the fishing problem a fishing agreement was negotiated. It came into force in 1978 and expired in 1984 whereupon negotiations commenced once more in an attempt to achieve new accord. The fishing industries of both countries and the conflicts which led to the …

Interstate Fisheries Management Problems: The Case Of Striped Bass, Richard Randall Schneider

Theses and Major Papers

The striped bass (Morone saxatilis), or rockfish, fishery has been important both commercially and recreationally for decades along the Atlantic seaboard. In recent years, though, the fishery has undergone a serious decline and, as a result, has elicited considerable public concern. Although specific reasons for the decline have not been pinpointed, it is clear that inconsistent management practices within the range of striped bass have done little to help the fishery's condition. An anadromous species, striped bass spawn in the fresh water reaches of estuaries, after which many of the individuals return to the coastal ocean. In the Atlantic, the …

Biology Of The Antarctic Krill (Euphausia Superba) And Fisheries Management Under The Convention On The Conservation Of Antarctic Marine Living Resources, Randa Ali Mansour

Theses and Major Papers

Interest in the development of a commercial fishery for Antarctic krill, the lack of a legal regime to govern and promote rational exploitation of Antarctic living resources, and a desire to avoid future conflicts between claimants and non-claimants regarding the control of an Antarctic marine fishery, as well as the desire to set a precedent for management and exploitation of non-living resources were incentives for the negotiation of the Convention on the Conservation of Antarctic marine Living Resources (CCAMLR). Furthermore, the Antarctic Treaty Consultative parties wished to maintain and solidify their control and enhance their collective legitimacy in the Antarctic …

The New England Fishing Industry: A Case For Altering Conditions Of Competition In Both The Fishery And In The Market, William Joseph Brennan

Theses and Major Papers

The New England fishing industry is presented in detail including an historical review, a discussion of current difficulties, and an examination of the public policy dilemma between resource conservation and industry promotion. Continuing efforts to revitalize the United States fishing industry are discussed and underlying problems that have had a negative impact upon the New England industry are outlined. Finally, an alternative public policy approach is developed which addresses fundamental difficulties in the new England region. This approach calls for an elimination of federal financial assistance to the fishing industry and a reduction in the amount of fishery imports reaching …

Premium Prices For Quality Fish: A Case Study Of The F/V Odin, John Sackton

Theses and Major Papers

During 1982, the F/V ODIN, a fishing vessel from the Port of New Bedford, participated in a program to improve fish quality on board through use of innovative fish handling techniques. The captain and crew hoped to sell higher quality fish at a premium price. This thesis examines the prices the F/V ODIN received prior to participating in this experiment, the price differentials the vessel actually received for landing higher quality fish, and the impact of the program on the prices received by the ODIN following the project. Overall, the ODIN received a price premium equal to 7.2% of the …

Cooperatives: Their Effectiveness And Limitations For Small-Scale Fisheries Development, Hiroaki Yonesaka

Theses and Major Papers

Increased experience in fisheries cooperatives of developing countries has called into question a long-held presumption about their desirability and feasibility. In this context, this study attempts to reformulate the cooperative approach for small-scale fisheries in a realistic policy framework. First, past failures of fisheries cooperatives are analyzed from three different angles: the uniqueness of the fishing industry, systems intrinsic to the cooperative, and development policy. Second, various possibilities of building viable cooperatives are explored by introducing two key concnpets: the strategic option and the operational option. On the one hand, the strategic option implies that it is imperative to integrate …

Economics Of The Pacific Whiting, Merluccius Productus, Fishery, Eric Anderson

Economics Faculty Publications

(First paragraph) Interest in the economics of Pacific whiting, Merluccius productus, production and consumption has been simulated in recent years by expanding U.S. participation in the fishery formerly dominated by foreign fishing and processing. This has raised several questions within the U.S. fishing industry: 1) Will it be profitable for additional U.S. fisherman and processors to enter the fishery? 2) What configuration will the U.S. Pacific whiting industry take? and 3) What will be the nature of markets for Pacific whiting products? This paper summarizes the conclusions of several reports and studies which bear on these questions.
