Department Of Fisheries Annual Report Highlights 1999 - 2000, Department Of Fisheries, Western Australia

Department of Fisheries Annual Reports

1999/2000 has marked a 'sea change' in fisheries management throughout Australia towards the principles of Ecologically Sustainable Development (ESD). This is a dynamic concept with an evolving framework that requires a balancing of social, economic and environmental considerations.

The principles of ESD - of using, conserving and enhancing the community's resources so that ecological processes, on which life depends, are maintained, and the total quality of fisheries, now and in the future, can be increased - are vital in a state, national and international context for Fisheries WA and its clients. Having fisheries that are governed under ESD principles is …

A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck

All Master's Theses

Satus Creek provides critical habitat for the Yakima River Basin steelhead. A diverse community of riparian vegetation is important for healthy fish habitat; vegetation changes can affect shade, cover, channel structure, water quality, and food availability. The purpose of this thesis is to analyze and illustrate riparian vegetation change, both temporally and spatially, along three separate reaches of Satus Creek. A Geographic Information Systems approach was applied to assess the vegetation change by comparing plant species composition and density on 1949 and 1995 aerial photographs. The GIS approach allowed patterns and trends in the vegetation to be identified. In less …

Fisheries Management Report No. 4 - Planning For The Further Development Of The Aquaculture And Marine Farming Industry At Jurien Bay, Dave Everall

Fisheries Published Reports

There is a well documented global requirement for some twenty million tonnes of edible sea foods from aquaculture in the next fifteen years. Most of the projected increase in production will need to be from mariculture because of limiting factors on land based aquaculture. At present, approximately 85%of all aquaculture occurs in the Asian region.

Globally, temperate water species have market advantages because of their ability to supply a growing market preference for a firm white fleshed fin fish. Although significant temperate water aquaculture occurs in various countries north of the equator, there are growing environmental concerns surrounding production of …

The Executive Director of the Fisheries Department of Western Australia performs many functions under the provisions of the Fish Resources Management Act 1994 ('the Act'). These functions often include decisions on whether to grant an authorisation in a particular case. This decision may involve consideration of the factors of what constitutes a 'fit and proper person' to hold an authorisation and in the circumstances whether the grant of ari authority is 'in the better interests of industry.' It is my function as Minister to provide policy guidelines …

Western Australian Fisheries - At A Glance (1997), Fisheries Department Of Western Australia

Fisheries Published Reports

Western Australia's fisheries are the envy of the world. The calibre of our research and management, and the skills of our fishermen, are recognised as second to none. We have pristine oceans and waterways from which we draw fish and fish products of the very best quality.

But while WA ranks as Australia's leading producer and exporter of fish and aquaculture products, we are not resting on our laurels. A major review of fisheries administration has cemented environmental and economic sustainability as the key management objectives, and industry now has greater scope for improving its competitiveness by pursuing new marketing …

Something Fishy Is Going On - Aquaculture, David Berry

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

Aquaculture id Australia's fastest growing primary industry. Product from fish farms is currently valued at $399 million, forecast to exceed $5oo million by 2000.

Whilst the figure pales into insignificance alongside world production (about $45 billion) it does represent a huge window of opportunity for prospective investors and for Australian primary producers who are keen to diversify.

David Berry reports on the prospects for yabbie and marron farming in Western Australia.

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.

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.

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 …

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.
