Development Of Semi-Intensive Aquaculture Technologies In Honduras: Summary Of Freshwater Aquacultural Research Conducted From 1983-1992, Bartholomew Green, David Teichert-Coddington, Terrill Hanson

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Aquacultural research has been conducted collaboratively in Honduras since 1983 by the International Center for Aquaculture and Aquatic Environments, Auburn University, and the Direccion General de Pesca y Acuicultura, Secretaria de Recursos Naturales. This research was carried out at the El Carao National Fish Culture Research Center, Comayagua, Honduras, under the auspices of the USAID-financed Pond Dynamics/Aquaculture Collaborative Research Support Program (PD/A CRSP). The goal of the PD/A CRSP is to increase tilapia yields by optimizing resource use in systems based predominantly on natural pond productivity.

Diversification In The Woolbelt, John Allen

Journal of the Department of Agriculture, Western Australia, Series 4

The productivity and diversification initiative for wool growers incorporates two leves of diversification.

Greatest emphasis is placed on industry wide increases in cropping intensity and in the range of crop types grown.

The second level involves non-traditional, alternative enterprises, each offering prospects for expansion of a limited number of wool growing businesses, suited to particular parts of the woolbelt.

The alternative enterprises include floriculture, aquaculture, export hay, farm tourism, commercial timber, horticulture and new animal industries.

A Study Of The Summer Steelhead, Oncorhynchus Mykiss In Several Intermittent Tributaries Of The Satus Creek Basin, Washington, Joel Denney Hubble

All Master's Theses

The summer steelhead, Oncorhynchus mykiss population was studied in three intermittent tributaries in the Satus Creek Basin. There was a strong tendency for post emergent fry, resulting from redds located in intermittent reaches to move downstream. However, survival to perennial flow conditions was very low. Steelhead production in Dry Creek appears to be lower than in Logy Creek, because of elevated water temperatures and minimal spring and summer stream flow.

Fisheries And Environmental Research By The Minnesota Sea Grant College Program, Donald C. Mcnaught

Journal of the Minnesota Academy of Science

ABSTRACT-Minnesota's Sea Grant College Program has funded research and outreach activities since 1977. Research results combined with public education setve the citizens, government, and businesses of the state. Research on commercial and sport fisheries, aquaculture, and environmental contamination is highlighted here. This article shows Sea Grant's contributions to understanding the Lake Superior ecosystem, including its chemical, biological, and human aspects.

Adaptation Of Striped Bass To Sea Water Following Direct Transfer From Freshwater: Morphological, Biochemical, And Physiological Parameters, Judy A. King

Electronic Theses and Dissertations

There has been heightened interest in the biology of striped bass (Morone saxatilis) because of increased pollution in their native spawning grounds and because of their extensive use in landlocked sport fisheries. Their euryhalinity makes them an excellent species for osmoregulation studies. The objective of this research was to study the rate of adaptation of striped bass gills to sea water (3% salt) after direct transfer from freshwater using biochemical (ion transport enzyme levels), physiological (chloride efflux), and ultrastructural methods. Striped bass have specialized osmoregulatory cells located on the interlamellar and afferent surfaces of their gill filaments as shown by …

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.

Aquaculture In Cooling Water Recirculated From A Generating Plant, John G. Woiwode, Ira R. Adelman

Journal of the Minnesota Academy of Science

Recirculating cooling water from an electric generating plant accumulated dissolved and suspended solids up to ten times that of the make-up water from the Mississippi River. Channel catfish (lctalurus punctatus) and tilapia (Tilapia mossambica) were grown In the cooling water, in clear well water, and in a mixture of the two for seven months as part of an investigation of the use of cooling water for commercial aquaculture. Health of both species was generally excellent in test and control waters; growth was commercially acceptable; bioaccumulation of contaminants was negligible. Organoleptic taste quality was not acceptable, although the cause of the …

Journal of the Minnesota Academy of Science

Recirculating cooling water from an electric generating plant accumulated dissolved and suspended solids up to ten times that of the make-up water from the Mississippi River. Channel catfish (Ictalurus punctatus) and tilapia (Tilapia mossambica) were grown in the cooling water, in clear well water, and in a mixture of the two for seven months as part of an investigation of the use of cooling water for commercial aquaculture. Health of both species was generally excellent In test and control waters; growth was commercially acceptable; bioaccumulation of contaminants was negligible.

Some Basics Of Marron Production, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

marron are native to the South-West of Western Australia, and are keenly sought by inland fisher-men. However, supplies do not equal the apparent demand.

One solution is to cultivate marron in farm dams, or more intensively as a commercial enterprise.

This article suggests a few guidelines for marron production.

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.
