Conference organizers and/or faculty included University of Colorado School of Law professors Betsy Rieke, David H. Getches, Michael A. Gheleta and Charles F. Wilkinson.

All across the country--in Congress, in state legislatures and in urban and rural communities--people are discussing why we should or should not protect biodiversity and how best to do so. Since the Endangered Species Act is up for reauthorization, a variety of reform proposals are being debated. Speakers--including natural resource scholars, experts from the private and nonprofit sectors, and government officials--will examine the rationale for biodiversity protection, the legal framework of the Endangered Species Act, and …


Offshore Constitutional Settlement 1995, H. G. Brayford, G. E. Lyon Jun 1996

Offshore Constitutional Settlement 1995, H. G. Brayford, G. E. Lyon

Fisheries Management Papers

The Offshore Constitutional Settlement OCS is a legal arrangement between the Commonwealth and State Governments, and defines control over the fisheries which operate off each State of Australia. For the Western Australian coast, the first set of arrangements took effect in 1987. The OCS of 1995 specifies five arrangements, under which the fisheries inside the 200 nautical mile approximately 370 km limit of the Australian Fishing Zone AFZ come under either State, Commonwealth, or joint control.


Assessment Of Kokanee Salmon, Oncorhynchus Nerka, Genetic Stocks In Flaming Gorge Reservoir, Utah-Wyoming, Michael F. Canning May 1996

Assessment Of Kokanee Salmon, Oncorhynchus Nerka, Genetic Stocks In Flaming Gorge Reservoir, Utah-Wyoming, Michael F. Canning

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I investigated the relative abundance, spatial distributions, return to the creel, and growth rates of two genetic stocks of kokanee salmon, Oncorhynchus nerka, in Flaming Gorge Reservoir, Utah-Wyoming. The two genetic stocks consist of fish from the two major spawning populations of kokanee in the reservoir. One population, Shore Spawners, spawns along the eastern shoreline of the Open Hills area of the reservoir. The other population, Sheep Creek, spawns in Sheep Creek, a tributary located in the Canyon area of the reservoir.

Mitochondrial DNA of kokanee from each population was analyzed to determine haplotype differences between stocks. These haplotype …


Habitat Selection And Movement Of A Stream-Resident Salmonid In A Regulated River And Tests Of Four Bioenergetic Optimization Models, Mark D. Bowen May 1996

Habitat Selection And Movement Of A Stream-Resident Salmonid In A Regulated River And Tests Of Four Bioenergetic Optimization Models, Mark D. Bowen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A bioenergetics model was constructed for stream-resident drift-feeding salmonids. Model predictions of surplus power (energy available per unit time for growth and reproduction) were not statistically distinguishable from observations of surplus power in three laboratory studies. Of 40 experimental trials in these three studies, the model correctly predicted surplus power in 39 cases (p < 0.05).

I collected observations of rainbow trout (Oncorhynchus mykiss) focal velocity and physical habitat availability in the Green River of northeastern Utah, USA (1988-1990). In the winter of 1988, Flaming Gorge Dam generated hydropower and delivered an lJDStable discharge regime with a higher mean discharge …


Recruitment Of Blue Crab, Callinectes Sapidus, Postlarvae To The Back-Barrier Lagoons Of Virginia's Eastern Shore, Robert D. Brumbaugh Apr 1996

Recruitment Of Blue Crab, Callinectes Sapidus, Postlarvae To The Back-Barrier Lagoons Of Virginia's Eastern Shore, Robert D. Brumbaugh

OES Theses and Dissertations

Most research on the early life history of the blue crab, Callinectes sapidus, has been conducted in large partially stratified estuaries such as the Chesapeake Bay. In contrast, little is known about the recruitment dynamics or habitat requirements of blue crab postlarvae (megalopae) in shallow well-mixed lagoonal systems that make up a considerable part of the species' range. In Virginia's coastal lagoons, planktonic blue crab megalopae are most abundant at night on flooding tides, and are not abundant during the daytime or on ebbing tides. This appears to enhance retention within the lagoons, despite the short residence time of water …


A Report On The Issues Affecting The Use Of The Dampier Archipelago, Peter Driscoll Mar 1996

A Report On The Issues Affecting The Use Of The Dampier Archipelago, Peter Driscoll

Fisheries Management Papers

This report was commissioned by the Minister for Fisheries following concerns about resource sharing, allocation of licences and leases for pearling and aquaculture, recreational and commercial fishing opportunities, and local residents continued ability to access the islands and marine areas of the Dampier Archipelago. The purpose of this report is to provide a scoping document for a marine planning study for the Dampier Archipelago for the Fisheries Department and the Minister for Fisheries.


Fishermen's Views On The Future Management Of The Rock Lobster Fishery: A Report Prepared On Behalf Of The Rock Lobster Industry Advisory Committee, The Marketing Centre, Rock Lobster Industry Advisory Committee Mar 1996

Fishermen's Views On The Future Management Of The Rock Lobster Fishery: A Report Prepared On Behalf Of The Rock Lobster Industry Advisory Committee, The Marketing Centre, Rock Lobster Industry Advisory Committee

Fisheries Management Papers

In June 1995, a self-completion survey of fishermen in the rock lobster fishery was sent out by The Marketing Centre to 589 licensees. A total of 206 valid responses were received. The questionnaire was fairly long and dealt with a number of complex issues. As such, this response rate of 36.0% compares favorably with the average for postal surveys of around 40.0%. The following represents the main findings from the survey.

Management Arrangements For Specimen Shell Collection In Western Australia, 1995, Jonathon Hs Barrington, C A. Campbell Feb 1996

Management Arrangements For Specimen Shell Collection In Western Australia, 1995, Jonathon Hs Barrington, C A. Campbell

Fisheries Management Papers

The Specimen Shell Fishery in Western Australia is based on the collection of marine species of the phylum Mollusca for the purposes of display, collection, cataloguing, classification and sale. Specimen shells may be alive or dead at the time of take and include beach-washed shells. Fossilised shells do not constitute specimen shells. This document has been prepared to detail the legislative requirements of the Western Australian Government, as well as to fulfill the requirements under the Commonwealth Wildlife Protection (Regulation of Exports and Imports) Act 1982 to allow for the export of specimen shells from Western Australian waters and the …


Genetic Analysis Of Rhinichthys Atratulus (Pisces: Cyprinidae) In North Central West Virginia, Alan Harper Tennant Jan 1996

Genetic Analysis Of Rhinichthys Atratulus (Pisces: Cyprinidae) In North Central West Virginia, Alan Harper Tennant

Theses, Dissertations and Capstones

The blacknose dace, Rhinichthys atratulus, is a cyprinid minnow common to shallow streams throughout North America. It has been shown to be sensitive to anthropogenic stress and a study of the genetic nature of R. atratulus populations may yield information about their habitats. In West Virginia, two subspecies of R. atratulus are present, R. a. atratulus and R. a. obtusus, which are separated by the Allegheny divide. In north central West Virginia, R. a. atratulus was observed in the Cheat River drainage, an area previously thought be within the range of R. a. obtusus. Fish of the R. a. atratulus …


Cytogenetic And Isozyme Analysis Of Two Species Of North American Cyprinid Fishes : Rhinichthys Cataractae And Nocomis Micropogon From The Cheat River Drainages Of West Virginia, Syam B. Stoll Jan 1996

Cytogenetic And Isozyme Analysis Of Two Species Of North American Cyprinid Fishes : Rhinichthys Cataractae And Nocomis Micropogon From The Cheat River Drainages Of West Virginia, Syam B. Stoll

Theses, Dissertations and Capstones

Nocomos micropoqon and Rhinichthys cataractae are species of cyprinid fishes that may hybridize to produce a nominally described species Rhynichthys bowersi. Rhynichthys bowersi is a rare fish endemic to a few watersheds mostly in West Virginia, especially the Cheat River drainage. The resolution of its proper taxonomic status is presently a concern to state and federal regulatory agencies. A number of investigators have determined relatedness of cyprinid fishes by examining chromosomal structure. Telomeres and nucleolar organizer regions are chromosome structures used in inter and intraspecific phylogeny. In this study, fibroblasts from N. micropoqon and R. cataractae were first …


A Review Of Ministerial Policy Guidelines For Rock Lobster Processing In Western Australia From The Working Group Appointed By The Minister For Fisheries And Chaired By Peter Rich, Peter Rich Dec 1995

A Review Of Ministerial Policy Guidelines For Rock Lobster Processing In Western Australia From The Working Group Appointed By The Minister For Fisheries And Chaired By Peter Rich, Peter Rich

Fisheries Management Papers

The rock lobster processing industry in Western Australia has a long history of management. Whilst management of the industry through the Fisheries Department has obviously been successful in helping to build the rock lobster industry into one of the State's major export industries, this approach is not without problems. With the introduction of the Fisheries Management Act 1994, the Minister for Fisheries deemed it appropriate to appoint an expert group to review the existing regulation of the rock lobster processing sector, draft the necessary guidelines to assist the Executive Director of the Fisheries Department make decisions on rock lobster processing …


The Impact Of The New Management Package On Smaller Operators In The Western Rock Lobster Fishery, Ross Gould Sep 1995

The Impact Of The New Management Package On Smaller Operators In The Western Rock Lobster Fishery, Ross Gould

Fisheries Management Papers

For the 1993/94 western rock lobster fishing season several new management strategies were introduced. The objective of the changes to the management package was to protect the rock lobster fishery. It was also to provide sufficient breeding stock to ensure viability of the industry. The most significant new measure was a temporary (two seasons) 18 percent pot reduction. Other changes were also made. There were considered sound reasons for reviewing and changing the previous management package. Despite this, some fishermen were critical of the new management package, and claimed that it unfairly disadvantaged smaller operators. Against this background, the Department …


West Coast Rock Lobster Fishery Management Plan 1995 - Draft For Public Comment, M. Moran Aug 1995

West Coast Rock Lobster Fishery Management Plan 1995 - Draft For Public Comment, M. Moran

Fisheries Management Papers

The purpose of this management plan is to regulate fishing for rock lobsters (Family Palimuridae) in waters off the west coast of Western Australia such that the breeding stock of rock lobsters is maintained at a level known to have generated adequate recruitment of young lobsters in the past. This management plan does not constitute a change in the management arrangements for the rock lobster fishery. It essentially replaces the West Coast Rock Lobster Limited Entry Fishery Notice 1993 made under the Fisheries Act 1905 and makes the required changes to wording and structure necessitated by the proclamation of the …


Bag And Size Limit Fishing Regulations From Around Australia - Current Information As At 1 July, 1995 - Third Australasian Fisheries Managers Conference, Rottnest Island, Wa, F. B. Prokop Aug 1995

Bag And Size Limit Fishing Regulations From Around Australia - Current Information As At 1 July, 1995 - Third Australasian Fisheries Managers Conference, Rottnest Island, Wa, F. B. Prokop

Fisheries Management Papers

This paper was originally prepared for the first National Fisheries Managers Conference in 1993. It is now updated and includes the current bag and size limits from around Australia as at 1 July, 1995. It is fairly obvious from this paper that there is a need for more cooperation between the states, particularly for species which have wide distributions. However, regional solutions can be a good approach for specific management needs, while general rules can be made more consistent in a number of cases.

Translocation Issues In Western Australia: Proceedings Of A Seminar And Workshop Held On 26th And 27th September 1994, F. B. Prokop

Fisheries Management Papers

The Recreational Fishing Advisory Committee (RFAC) approved holding this translocation seminar to air the translocation of fish for recreational enhancement in a public forum. This forum will identify issues including establishing common ground between the variety of interest groups which are represented. Contentious areas which require further investigation and consultation should become apparent, and assist the formulation of appropriate policies on translocation for Western Australia.
