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.

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.


Management Of The Northern Demersal Scalefish Fishery, Jane Fowler Jun 1995

Management Of The Northern Demersal Scalefish Fishery, Jane Fowler

Fisheries management papers

In mid 1994, the Fisheries Department of Western Australia announced that it would prepare a discussion paper setting out options for future management of the demersal scalefish fishery off the Kimberley coast. This paper, which was to be the start of a wider consultative process, was also to include options for possible further development of the trap and line fisheries. This paper is only the first step in a process for developing formal long term management arrangements under the new fisheries legislation, the Fish Resources Management Act 1994. Its aim is to provide some background and to present some management …


Report On Future Management Options For The South West Trawl Limited Entry Fishery, South West Trawl Limited Entry Fishery Working Group Jun 1995

Report On Future Management Options For The South West Trawl Limited Entry Fishery, South West Trawl Limited Entry Fishery Working Group

Fisheries management papers

As a result of community concern regarding trawling, the current management rules for the South West Trawl Limited Entry Fishery were finalised in February 1989 and the final plan was gazetted in October of that year. However, there was public disquiet about this trawling, and as a result of this disquiet, a research program was initiated by the Fisheries Department with funding received from both the Commonwealth and State Governments. The scientific report, "The impact of trawling for saucer scallops and western king prawns on the benthic communities in coastal waters off south-western Australia" by L J B Laurenson, P …


Management Options (Discussion Paper) For The Shark Bay Snapper Limited Entry Fishery, Shark Bay Snapper Limited Entry Fishery Working Group, Doug Bathgate Jun 1995

Management Options (Discussion Paper) For The Shark Bay Snapper Limited Entry Fishery, Shark Bay Snapper Limited Entry Fishery Working Group, Doug Bathgate

Fisheries management papers

At the Annual Management Meeting of the Shark Bay Snapper Limited Entry Fishery held on 22 July 1994 industry put forward a proposal that supplementary and non-transferable quota that was "lost" to the fishery when a licence holding non-transferable quota was transferred should be retained by the Fisheries Department and leased back to licence holders on an annual basis. As a result of this proposal and the fact that the management arrangements for the fishery are extremely complex and in need of simplification, the Minster for Fisheries approved the establishment of a Working Group to examine the lease-back proposal and …

The Best Available Information - Its Implications For Recreational Fisheries Management, F. B. Prokop May 1995

The Best Available Information - Its Implications For Recreational Fisheries Management, F. B. Prokop

Fisheries management papers

Workshop at Second National Fisheries Managers Conference, Bribie Island, Queensland, October 18, 1994. Recreational fisheries management is one of the growth areas in Australian fisheries. The Australian Society for Fish Biology Workshop topic for its 1994 Conference was Recreational Fishing - What's the Catch. It was acknowledged at the ASFB conference that there were generally poor levels of information and for the lower value commercial and recreational fisheries there may be no way to gather definitive research data for the foreseeable future. However, in even the high profile fisheries, public perceptions, attitudes, and political will do not allow for the …

Pollination Of The Crown Imperial Fritillaria Imperialis By Great Tits Parus Major, Winfried S. Peters, Michael Pirl, Gerhard Gottsberger, Dieter Stefan Peters Feb 1995

Pollination Of The Crown Imperial Fritillaria Imperialis By Great Tits Parus Major, Winfried S. Peters, Michael Pirl, Gerhard Gottsberger, Dieter Stefan Peters

Winfried S. Peters

Visitations of flowers of the Crown Imperial by Great Tits at two different locations in Hessen, Germany, in 1990 and 1993 are described. The observations prove that flowers were visited because of the nectar; most likely pollination occurs during this visits. Similar reports from Europe are discussed. The significance of specific interactions including ecological generalists such as the Great Tit is considered in the context of the phylogenetic reconstruction of the development of co-adaptive syndroms.


Implications Of Native Title Legislation For Fisheries Management And The Fishing Industry In Western Australia, Patricia Summerfield Feb 1995

Implications Of Native Title Legislation For Fisheries Management And The Fishing Industry In Western Australia, Patricia Summerfield

Fisheries management papers

This paper seeks to examine the key issues of both State and Commonwealth native title legislation for the fishing industry and fisheries management in Western Australia. Considerations for Aboriginal involvement in the industry and long-standing as well as recent concessionary arrangements for traditional usage of fish resources are examined. Industry reactions and future plans to accommodate native title in a positive framework are explored.


Anophryocephalus Inuitorum Sp. Nov. And A. Arcticensis Sp. Nov. (Eucestoda: Tetrabothriidae) In Ringed Seals (Phoca Hispida Hispida) And Harp Seals (Phoca Groenlandica) From High-Latitude Seas Of Eastern Canada And The Arctic Basin, Eric P. Hoberg, Lena N. Measures Jan 1995

Anophryocephalus Inuitorum Sp. Nov. And A. Arcticensis Sp. Nov. (Eucestoda: Tetrabothriidae) In Ringed Seals (Phoca Hispida Hispida) And Harp Seals (Phoca Groenlandica) From High-Latitude Seas Of Eastern Canada And The Arctic Basin, Eric P. Hoberg, Lena N. Measures

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Anophryocephalus inuitorum sp. nov. and A. arcticensis sp. nov. are described from ringed seals (Phoca hispida hispida) in the eastern Canadian Arctic; the latter species is also reported from harp seals (Phoca groenlandica) in the Gulf of St. Lawrence. Anophryocephalus inuitorum is most similar to A. skrjabini, but can be distinguished by fewer testes (14-27) and smaller dimensions of the strobila, neck (3.0-5.9 mm long), and cirrus sac (31-70 μm long), diameter of the genital atrium (44 -68 pm), and length of the male canal (23-42 μm long). Anophyrocephulus arcticensis resembles A. nunivakensis in the …

Finfish Communities Of Two Intertidal Marshes Of The Goodwin Islands, York River, Virginia, Lisa Ann Ayers Jan 1995

Finfish Communities Of Two Intertidal Marshes Of The Goodwin Islands, York River, Virginia, Lisa Ann Ayers

Dissertations, Theses, and Masters Projects

The finfish communities using the intertidal surfaces of a bay-exposed marsh and a sheltered, channel marsh of the Goodwin Islands, York River, Virginia were studied from May to November 1994. Samples were taken approximately twice monthly using a flume weir at three stations in each marsh. Species composition, abundance and biomass were estimated, and growth patterns and production rates were described for the dominant species. A total of 3001 fish were collected from 11 species and 8 families. Fundulus heteroclitus dominated both marshes and accounted for 83.07% of the total number of fish caught, and 84.83% of the total biomass …


Spawning And Ecology Of Early Life Stages Of Black Drum, Pogonias Cormis, In Lower Chesapeake Bay, Louis Broaddus Daniel Iii Jan 1995

Spawning And Ecology Of Early Life Stages Of Black Drum, Pogonias Cormis, In Lower Chesapeake Bay, Louis Broaddus Daniel Iii

Dissertations, Theses, and Masters Projects

During spring 1990 and 1991, ichthyoplankton surveys were conducted in lower Chesapeake Bay to estimate seasonal egg production, population biomass and the impact of predation by gelatinous zooplankton on early life stages of black drum, Pogonias cromis. Rearing experiments indicated that at least three species of sciaenid (silver perch, Bairdiella chrysoura; weakfish, Cynoscion regalis and P. cromis) were spawning in the survey area during both years. Specific identification of eggs based on previously published ranges of outside egg diameter (OED) were not reliable due to considerable overlap in diameter distributions. Analysis of weekly OED frequency revealed the presence of three …

Historical Biogeography And Modes Of Speciation Across High-Latitude Seas Of The Holarctic: Concepts For Host-Parasite Coevolution Among The Phocini (Phocidae) And Tetrabothriidae (Eucestoda), Eric P. Hoberg Jan 1995

Historical Biogeography And Modes Of Speciation Across High-Latitude Seas Of The Holarctic: Concepts For Host-Parasite Coevolution Among The Phocini (Phocidae) And Tetrabothriidae (Eucestoda), Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Species of Anophryocephalus are host-specific parasites of pinnipeds in the Holarctic. Phylogenetic analysis of 7 species postulates A. anophrys as the basal taxon and A. inuitorum as basal to A. skrjabini; A. arcticensis is basal to A. nunivakensis and A. eumetopii + A. ochotensis (single tree; consistency index = 74.4%; homoplasy slope ratio = 36.45%). Evaluation of host and geographic distributions postulates ringed seals of the Atlantic-Arctic as ancestral hosts, and the Arctic basin as a paraphyletic area with respect to the North Pacific. Cospeciation within this assemblage was dependent on intense isolation of small effective populations of definitive hosts …

Nutrition And Feeding In Striped Bass Morone Saxatilis Larvae: Lipid And Fatty Acid Requirements And Microencapsulated Diets, Sureyya Ozkizilcik

Dissertations, Theses, and Masters Projects

There has been a growing interest in the commercial aquaculture of striped bass, Morone saxatilis. Little is known, however, about the nutritional requirements and feeding physiology of striped bass larvae. The objectives of this study were (a) to evaluate the efficiency of the live food enrichment techniques in studying the nutritional requirements for polyunsaturated fatty acids (PUFA), phospholipids and free amino acids, (b) to determine the ontogenetic changes of lipolytic enzymes, and (c) to develop a microencapsulated diet for striped bass larvae as full or partial replacement of live food. Three enrichment techniques, namely, microencapsulated fish oil, yeast/fish oil emulsion …

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 1994-December 1994 : Annual Progress Report, Herbert M. Austin, A. Dean Estes, Donald M. Seaver

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a juvenile striped bass seine survey from 1967 through 1973 and from 1980 through the present. The primary objective has been the monitoring of the relative annual recruitment success of juvenile striped bass in the spawning and nursery areas of Lower Chesapeake Bay. The survey was funded in it's initial period by the U.S. Fish and Wildlife Service and then reinstated in 1980 with funding from the National Marine Fisheries Service under the Emergency Striped Bass Study program. Commencing with the 1988 annual survey, support of the program has been made …
