Fishery Harbor Development: A Case Study Of A Connecticut Coastal Community, Stonington, Connecticut, James L. Wallace

Marine Affairs Theses and Major Papers

This study was undertaken to investigate the problems and procedures encountered in the development of fishery harbors in Connecticut. Harbor facilities along the coast are in great disrepair or have been completely eliminated to allow for more profitable coastal uses. In addition, conflict between recreational and commercial fishermen for existing space has created a shortage of commercial harbor facilities. Because of this need, state and local officials have begun to investigate viable harbor development alternatives for Connecticut.

By-Catch: Over The Side Discards, An Assessment And An Alternative, Alan R. Bunn

Marine Affairs Theses and Major Papers

The incidental capture and resultant mortality of numerous fin-fish and other species of marine organisms by non-selective types of fishing gear constitute a major waste of the various fishery resources. The magnitude of the discarded by-catch and its effects upon the major fisheries is examined. Specific gear types contributing to the problem will be identified. The Gulf of Mexico shrimp fishery of the U.S., which annually catches over a billion pounds of unwanted fin-fish or “trash-fish” will be examined and an evaluation of the continuing development of selective shrimp trawling gear specifically designed to reduce the incidental capture of sea …

The Effects Of Regulation On Aquaculture Development, Derek S. Busby

Marine Affairs Theses and Major Papers

A comparative study of the regulatory frameworks surrounding aquaculture in the states of Florida, Mississippi, and Rhode Island is conducted beginning with a generalized study of basic legal premises of aquaculture-related law common to each state. This is followed by a detailed study of the statutory authority for aquaculture regulation and the agencies which control aquaculture activities in each state. In conjunction with the law analysis an Index of Specialization (ISP) study is conducted for each state to determine a relative ranking of diversity of crop production relative to each state’s overall aquaculture production.

Marine Resources: The Presentation Of A Business Plan, K. Scott Colby

Marine Affairs Theses and Major Papers

The once questionable technology of hatchery production has become routine and, with the recent development of up-welling techniques, is more effective and efficient. The supply of natural shellfish and fishery stocks is on the decline and this trend is expected to continue. Aquaculture has been the solution to this problem in many European countries and the United States is currently attempting to remove domestic obstacles through its National Aquaculture Plan. The proprietor has experience in the production of various marine invertebrates and has designed, built and operated a producing shellfish hatchery. By using a unique up-welling juvenile culture system a …

Factors Affecting Reproductive Success Of Bonytail Chubs And Razorback Suckers In Lake Mohave, Michael A. Bozek, Larry J. Paulson, James E. Deacon, U.S. Department Of Interior, Fish And Wildlife Service

Publications (WR)

Razorback suckers (Xyrauchen texanus) and bonytail chubs (Gila elegans) were once widespread throughout the Colorado River system. The ranges and populations of these native species and others have declined in the past 50 years. Bonytail chubs appear to be extremely rare and possibly nearing extinction in the Upper Colorado River Basin. The razorback sucker is widely distributed in the upper river but is considered rare throughout most of that range and is also rare in the Grand Canyon. Razorback suckers are abundant only in a few habitats in the upper river. They congregate and spawn over …

The Joint Venture Controversy: A Short-Term Solution For A Long-Term Fisheries Policy, Laurie A. Frost

Marine Affairs Theses and Major Papers

This paper will examine the development of joint ventures under the FCMA, the legislative and regulatory measures designed to control these ventures and the procedures for establishing a joint venture. More recent developments in joint venture policy will be examined, including the controversy over squid joint ventures on the East Coast, to determine what the objectives are and what current policy is regarding join ventures. The debate between harvesters and processors will be put forth as a way of summarizing the costs and benefits of joint ventures to the industry as a whole.

The Growth And Feeding Behavior Of Juvenile Spot, Leiostomus Xanthurus Lacepede, In The Nursery Region Of The James River, Virginia, John Thomas Mccambridge Jr.

OES Theses and Dissertations

The in situ growth and feeding behavior of juvenile spot, Leiostomus xanthurus Lacepede, was investigated for populations in the nursery area of the James River, Virginia. Growth of juvenile spot was found to be fairly rapid (11.34 mm/month, standard length) during their first summer in the nursery grounds, but it levelled off in the autumn. The mean size of spot after the first year was calculated to be 195 mm total length. The weight-length relationship was log W = -5.018 + 3.246(log L), where W = wet weight in grams and L = standard length in millimeters.

Juvenile spot appeared …

The Effect Of Crowding On Growth Of The Cichlid Fish, Oreochromis Mossambicus, Bonnie A. Barrows

OES Theses and Dissertations

It has been reported that the Java tilapia, Oreochromis mossambicus, displays hypersensitivity to a substance it produces when biomass levels in a flow-through culture system exceed 20 g/1, resulting in reduced growth and high mortality. Experiments on the growth of this species in small tanks were conducted in order to determine whether O. mossambicus produces a growth-inhibiting compound under crowded conditions. This species was successfully maintained at biomass levels of 38 g/1 and 57 g/1 with a total mortality of only 4.5%.

The Java tilapia can grow rapidly in small aquaria, as indicated by the data taken during Experiment …

A Model Of The Population Dynamics Of The Blue Crab In Chesapeake Bay, Betty Springer Hester

OES Theses and Dissertations

This study has particular application to the blue crab fisheries in Chesapeake Bay, an economically important industry whose successful management has been hindered by relatively poor understanding of the population dynamics. Recent biological studies have indicated a systematic spawning behavior which seems designed for ejection of larvae seaward from the bay entrance where they spend their pre-metamorphosis stages in the neuston. A physical mechanism for retention of the larvae in sufficient proximity to the bay entrance for their return at the proper time which involves the action of wind stress in shallow waters is proposed. Since the supply of blue …

The Effect Of The Endangered Species Act Of 1973, Robert Palmer Yankle Ii

Marine Affairs Theses and Major Papers

Scrimshaw, as an art form, had just recently risen a few notches above the state of obscurity. There are still millions of Americans who probably know nothing about it. Inextricably linked with the whaling industry for years, the scrimshaw industry has recently undergone a remarkable transition. When whaling ended in the United States, scrimshaw moved ashore and some people found out that there was a great deal of money to be made in the scrimshaw business. but with the passage of the Marine Mammals Protection Act in 1973, scrimshanders found themselves being tightly regulated by the Federal government. This paper …

Impact Of The Law Of The Sea Treaty On The Soviet Fishing Industry, Gary Lee Roemmich

Marine Affairs Theses and Major Papers

The signing of the United Nations Conference on the Law of the Sea (UNCLOS) Treaty was the maturation of an idea that was born thirty-six years ago. That treaty placed into effect the 200 mile exclusive economic zone (EEZ). A universal 200 mile EEZ could be a death knell for the high-seas fishing fleets we know today as the majority of the major fishing grounds lie within 200 miles of the coast. The Soviet Union presently has the largest fishing fleet in the world and will perhaps feel the largest impact from the treaty signing. This paper intends to evaluate …

The American Lobster Fishery Management Plan: An Assessment Of Its Impact On The New Hampshire Lobster Industry, John C. Belcher

Marine Affairs Theses and Major Papers

Exclusive fishery management jurisdiction between three and twelve nautical miles from the coast was granted to the Federal government by Congress in 1966. No federal regulations governing fishery management were ever promulgated, however. In 1972 an attempt was made to establish management regulations. Regional councils were formed to discuss industrial, managerial and scientific problems associated with fisheries within the territorial sea. Their success was limited. Not until the Fishery Conservation and ManagementAct of 1976 (PubIc Law 94-265) was enacted did a sound management structure exist at the federal level for fisheries regulation. This Act (FCMA) established a fishery conservation zone …

Fisheries Report No 59 - Potential Fisheries Capability Of The Ord In The Short, Medium And Long Terms, Dr N. Morrissy

Fisheries Research Reports

This report examines the history, future and problems of various methods for development and exploitation of the fisheries resources of the Ord.

The primary resource is the array of native fish and crustacean species, with the possible introduction of other desirable or noxious species being a subject for consideration.

Water resources, supporting these species, are the remaining natural Ord River downstream from the Diversion Dam at Kununurra, the stillwaters of Lake Kununurra and Lake Argyle, and, for aquaculture, the controlled distribution of water supply over the flat land of the irrigation system (Fig. 1). Another recognized resource is the climatic …

Report No 58 - 1982 - Review Of Rainfall And Wetlands In The South-West Of Western Australia, J. A.K. Lane, D. R. Munro

Fisheries Research Reports

An account is given of involved the biological principles in decisions concerning duck-shooting seasons in the south-west of western Australia.

Conditions for waterfowl during 1982 are described through the use of rainfall statistics and data obtained from the Department's wetland monitoring programme.

1982 was characterized by exceptionally high rainfall in January and well-below average from February to October.

1982 was the seventh consecutive year of below-average rainfall in all five Meteorological of the south-west. 1976 to 1982 has thus been the south-west's driest seven-year period for more than seventy years.

The record-breaking rains of January caused widespread flooding in the …

The Effects Of Limited Food Availability On The Striped Bass Fishery In Lake Mead, John R. Baker, Larry J. Paulson

Publications (WR)

The original range of striped bass (Morone saxatilis) was along the Atlantic Coast. They were introduced into the lower Sacramento River in 1879 and are now also found along the Pacific Coast. A landlocked striped bass fishery was established in Santee-Cooper Reservoir, South Carolina, in 1954, and they have since been introduced into numerous other reservoirs, including Lake Havasu, Lake Mead and Lake Powell on the Colorado River. Striped bass were introduced into Lake Mead in 1969 in response to declines in the largemouth bass (Micropterus salmoides) fishery that occurred during the 1960s and in order to further utilize the …

Limiting Swine Stress With Evaporative Cooling In The Southeast, Robert L. Fehr, K. T. Priddy, Samuel G. Mcneill, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

Three-hourly weather data for 7 locations in the Southeast and Central United States were used to evaluate the feasibility of evaporative cooling for reducing swine stress. Stress was defined as a relationship between dry and wet bulb temperatures which exceeded a stress index of 85. This analysis indicates that properly installed evaporative coolers could reduce the number of hours that stress would occur in swine facilities from 89.6 to 96.4% depending on location.

Historical Patterns Of Phytoplankton Productivity In Lake Mead, Richard T. Prentki, Larry J. Paulson

Publications (WR)

Lake Mead was impounded in 1935 by the construction of Hoover Dam. The Colorado River was unregulated prior to then and therefore was subjected to extreme variations in flows and suspended sediment loads. Hoover Dam stabilized flows and reduced suspended sediment loads downstream, but Lake Mead still received silt-laden inflows from the upper Colorado River Basin. The Colorado River contributed 97% of the suspended sediment inputs to Lake Mead, and up to 140 x 1O⁶ metric tons (t) entered the reservoir in years of high runoff. Most of the sediments were deposited in the river channel and formed an …

Comparison Of Fishery Policies And Management Techniques Of The United States And Iceland, Ted I. Lillestolen

Marine Affairs Theses and Major Papers

In 1976, the United States enacted the Fishery Conservation and Management Act (FCMA), presently referred to as the Magnuson Fishery conservation and Management Act (MFCMA). The legislation is a complex and detailed document establishing for the first time a national fishery policy. The Act also created an organizational structure designed to implement this new policy. Since the Act's implementation, there has been a great deal of controversy, especially generated by the commercial fishermen. This paper focuses on Iceland, primarily because of its great economic dependency on its fisheries resources, unlike the United States.

A Laboratory Study Of Nongenetic Embryonic Adaptation To Salinity And Its Subsequent Effects Upon Larval Development Of The Grass Shrimp Palaemonetes Pugio Holthius, Paul Jay Anninos

OES Theses and Dissertations

Fertilized embryos of the grass shrimp Palamonetes pugio Holthuis (Decapoda; Caridea) were exposed to two levels of salinity [5 ppt (exposed) and 20 ppt (control)] during incubation to determine the extent to which embryonic adaptation influences subsequent larval development. Larval response to embryonic exposure was measured at three salinities (5 ppt, 10 ppt, and 20 ppt) as the fraction of larvae surviving to metamorphosis and the duration (in days) of larval development. The survival rate of larvae hatched from control, or non-adapted, embryos was significantly influenced by rearing salinity. The differences in survival of pre-adapted larvae (exposed group), however, were …

Report No 56 - 1981 Review Of Rainfall And Wetlands In The South-West Of Western Australia, J. A.K. Lane, D. R. Munro

Fisheries Research Reports

An account is given of the biological principles involved in decisions concerning duck-shooting seasons in the south-west of Western Australia.

The conditions for waterfowl which prevailed during 1981 are described through the use of rainfall statistics and data obtained from the Department's wetland monitoring programme.

Rainfall was generally average over central and northern areas of the south-west during 1981. Rainfall in southern areas, however, was generally

below to much-below-average, although south coastal areas from Augusta to Albany received average falls.

Unusually heavy falls were recorded in North Coastal, North Central and Central Coastal Districts in May, and average falls were …

Conservation Measures In The Interim Fishery Management Plan For Atlantic Groundfish, Andrew P. Matykiewicz

Marine Affairs Theses and Major Papers

The conservation measures used in the Interim Fishery Management Plan for Atlantic Groundfish (IFMP) were analyzed. The management techniques used include a minimum mesh size, minimum fish size and haddock spawning area closure. However the mesh regulation does not adequately address the IFMP conservation objectives. Without amendment, the IFMP cannot prevent overfishing as it is required to do by the Magnuson Fishery Conservation and Management Act (MFCMA). The use of a non-numeric Optimum Yield (OI) for groundfish is inappropriate without a definition of overfishing and without a contingency plan to prevent overfishing.

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

Marine Affairs 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

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

Marine Affairs 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 …

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

Marine Affairs 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

Marine Affairs 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

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 …
