Optimum Yield And The Fcma: Uneven Distribution Of Management Burden, Herrick J. Johnson Dec 1981

Optimum Yield And The Fcma: Uneven Distribution Of Management Burden, Herrick J. Johnson

Theses and Major Papers

Until the establishment of the Fishery Conservation and Management Act of 1976 (FCMA), fish outside the United States' twelve mile fishery zone were, according to international law, common property and belonged to the nation or individual that caught them. This common property law was based on the concept that fish resources were so large that no amount of fishing would interfere with the right of others to catch fish. Modern technology, however, has created equipment that enabled foreign and domestic fishermen to over-fish the resource. A reduced domestic catch led coastal fishermen to support a bill that unilaterally extended the …


A Quantitative Description Of Migratory Behavior Of The Brown Shrimp (Penaeus Aztecus) With Applications In Fisheries Management, Anne Madolyn Babcock Oct 1981

A Quantitative Description Of Migratory Behavior Of The Brown Shrimp (Penaeus Aztecus) With Applications In Fisheries Management, Anne Madolyn Babcock

OES Theses and Dissertations

A quantitative description of the migratory behavior of the brown shrimp, Penaeus aztecus, was established using the density approach. A theoretical time density was estimated by the proportion of catch and catch per boat hour NOAA-NMFS fisheries statistics collected in Pamlico Sound, the Neuse River, and Core Sound. A clear quantitative description of brown shrimp migratory timing is found in the time densities. The impact of various physical tactors on the progress of the fishery in time and space can be objectively evaluated by using the time density statistics as dependent variables in modeling efforts. The distributions also enable …


Where Have All The Stripers Gone?: An Analysis Of The Decline In The East Coast Striped Bass Fishery, Anthony P. Chatowsky May 1981

Where Have All The Stripers Gone?: An Analysis Of The Decline In The East Coast Striped Bass Fishery, Anthony P. Chatowsky

Theses and Major Papers

Beginning in 1975 striped bass sports fishermen noticed a decrease in fish around. This decline was cause for alarm in 1977 when few striped bass were caught from shore. Commercial catch statistics showed that in 1973, 13,504,000 pounds of bass were landed. In 1979 the poundage was 3,492,000, a significant drop of 74%. This led to the development of state and regional striped bass advisory committees, an N.M.F.S. and U.S. Fish and Wildlife Emergency Action Plan and Congressional appropriation of 4.7 million dollars in 1979 to study the problem. The problem is multifactored and solutions lie in consistent coastal management …


Toward The Marketing Of Seafood Harvested In New England, Daniel R. Kilty Ph.D May 1981

Toward The Marketing Of Seafood Harvested In New England, Daniel R. Kilty Ph.D

Theses and Major Papers

In this study the author will concentrate on the marketing activitiesof the U.S. commercial fishing industry. The study will use examples from New England to illustrate various points covered in the study. Particular reference will be made to the geographic area of Southern New England and move specifically to Point Judith, Rhode Island and New Bedford, Massachusetts. The study is divided into two parts. Part I reviews the situation in the industry prior to 1976, the Fishery Conservation Management Act, theU.S./Canadian East Coast Fisheries Agreement and the American Fisheries Promotion Act. Part II applies the marketing mix to the industry …


Seasonal Temperature Preference Of Adult Mountain Whitefish, Prosopium Williamsoni, Jean M. Ihnat May 1981

Seasonal Temperature Preference Of Adult Mountain Whitefish, Prosopium Williamsoni, Jean M. Ihnat

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Temperatures selected seasonally by adult mountain whitefish were measured in the laboratory in a horizontal gradient. Final preferendum estimates, based on acute (3-hour) preference tests conducted with fish acclimated to 5, 10, and 15 C each season, were 17.7 C (pre-spawning), 11.9 C (post-spawning), 9.9 C (winter), and 16.3 C (spring). Seasonal influence on temperature selection was evident on the basis of differences in final preferenda, covariance analysis of responses of laboratory-acclimated fish, and temperature selection by fish held at ambient river temperatures. Post-spawning and winter groups selected lower temperatures than did pre-spawning and spring groups. Pre-spawning fish selected temperatures …


The Rhode Island Quahogger: Candidate For The List Of Endangered Species?, James M. Korney Apr 1981

The Rhode Island Quahogger: Candidate For The List Of Endangered Species?, James M. Korney

Theses and Major Papers

It is the hypothesis of this paper that today the livelihood of the independent Narragansett Bay quahogger is faced with two potentially dangerous threats; water pollution in upper Narragansett Bay and the prospect of an expanding aquaculture industry in the lower bay. Unless the state of Rhode Island properly interprets and enforces existing state legislation to protect the quahoggers interests, his very livelihood will be jeoprodized. This paper will examine the legal, political, economic, and environmental affects of water pollution in upper Narragansett Bay and an expanding aquaculture industry in the lower bay in their relation to the Rhode Island …


Municipal Sewage Treatment: Problems And Considerations, George R. Johnson Apr 1981

Municipal Sewage Treatment: Problems And Considerations, George R. Johnson

Theses and Major Papers

The coastal areas are vital to the economic and physical well being of the United States. Virtually every facet of our way of life is related in some fashion to these coastal areas. Ocean borne transportation moves not only vast quantities of raw materials, but also many of the intermediate and final products that are then manufactured to their related market areas. Fisheries provide vast amounts of food and employment for many of our people. In addition, the coasts are a continuing source of enjoyment and recreation for millions of our citizens. Coastal waters provide much of the water necessary …


Growth And Recruitment Of Two Penaeids In The Bay Of St. Louis, Mississippi During 1979, Teresa C. Heaton Apr 1981

Growth And Recruitment Of Two Penaeids In The Bay Of St. Louis, Mississippi During 1979, Teresa C. Heaton

OES Theses and Dissertations

Juvenile brown (Penaeus aztecus, Ives) and white (Penaeus setiferus, Linnaeus) shrimp were collected from two stations of a nursery area in St. Louis Bay Mississippi, during May to October, 1979. Periods of shrimp recruitment and growth were determined to discern whether the concurrent environmental variables of salinity and temperature had an influence on shrimp abundance and yield. Growth estimates were obtained from length frequency measurements of trawl samples taken over a 24-h period per month from each station. An analysis of variance of length versus the variables of sex, month, station, time of day, salinity and …


Promotion Of Distant-Water Fishing Industry In Taiwan, Dah-Wen Shieh Jan 1981

Promotion Of Distant-Water Fishing Industry In Taiwan, Dah-Wen Shieh

Theses and Major Papers

The growth of distant-water fishing industry in Taiwan has been steady during the period from 1965-1973. However, since 1973, the slow expansion of distant-water fisheries has been reflected in both the production side and the decreasing catch per unit effort. The increasing operation costs and the shrinking fishing grounds are mainly attributable to the limitation of distant-water fishing industry. The small scale of fishing companies with small-sized vessels also resulted in the inefficient operation in this highly competitive business. For Taiwan, distant-water fishing is not only a means of meeting general protein requirements for its population but also an important …
