Bioeconomic Evaluation Of Commercial-Scale Stock Enhancement In Abalone, Anthony M. Hart, Lachlan W.S. Strain Feb 2016

Bioeconomic Evaluation Of Commercial-Scale Stock Enhancement In Abalone, Anthony M. Hart, Lachlan W.S. Strain

Fisheries research reports

The evaluation of commercial-scale stock enhancement was undertaken to determine its viability in the Western Australian Greenlip Abalone fishery. The key outcome of the project is that commercial-scale abalone stock enhancement is environmentally and economically achievable. The bioeconomic analysis revealed significant economic potential of a stock enhancement program for Australian Haliotis laevigata fisheries.


A Summary Of The Department Of Fisheries, Western Australia Invertebrate Research At Cocos (Keeling) Islands 2006-2011, Lynda M. Bellchambers, Scott N. Evans Feb 2013

A Summary Of The Department Of Fisheries, Western Australia Invertebrate Research At Cocos (Keeling) Islands 2006-2011, Lynda M. Bellchambers, Scott N. Evans

Fisheries research reports

The Cocos (Keeling) Islands are located in the Indian Ocean (12° 12” S, 96° 54” E). The group is comprised of two separate coral atolls, consisting of 27 islands. The southern atoll consists of 26 islands, surrounding a shallow lagoon, two of which are inhabited with a total population of approximately 600 people. Management of the Cocos (Keeling) Islands’ fish resources is conducted by the Department of Fisheries Western Australia (DoF), on behalf of the Commonwealth Government, under a Service Delivery Agreement (SDA). Between 2006 and 2011 DoF has conducted annual risk assessments to focus research and management objectives for …


Western Rock Lobster Ecology – The State Of Knowledge - Marine Stewardship Council - Principle 2: Maintenance Of Ecosystem, Lynda M. Bellchambers, P Mantel, Arani Chandrapavan, Matthew B. Pember, Scott Evans Jul 2012

Western Rock Lobster Ecology – The State Of Knowledge - Marine Stewardship Council - Principle 2: Maintenance Of Ecosystem, Lynda M. Bellchambers, P Mantel, Arani Chandrapavan, Matthew B. Pember, Scott Evans

Fisheries research reports

The commercial fishery is managed in three zones: south of latitude 30°S (Zone C), north of latitude 30°S (Zone B) and a third offshore zone (Zone A) around the Abrolhos Islands (Figure 1.3). Effort is evenly split between the southern and northern zones through the implementation of management controls aimed at addressing zone-specific issues. These issues include different maximum size restrictions and seasonal opening and closing dates. This report focuses on the state of the western rock lobster ecology at the date of publication.


Ranked Risk Assessment For Bycatch In Multiple Fisheries: A Bioregional Risk Assessment Method, Richard Evans, Brett W. Molony Oct 2010

Ranked Risk Assessment For Bycatch In Multiple Fisheries: A Bioregional Risk Assessment Method, Richard Evans, Brett W. Molony

Fisheries research reports

This report demonstrates a method to rapidly assess the cumulative risk to sustainability of bycatch species of multiple fisheries. The method draws on other techniques already published in scientific literature and adds a new cumulative ranked estimate of total catch across multiple fisheries.


Biological Synopsis Of The Black Bream, Acanthopagrus Butcheri (Munro) (Teleostei: Sparidae) In Western Australia With Reference To Information From Other Southern States, Jeffrey V. Norriss, J E. Tregonning, Rod C J Lenanton, Gavin A. Sarre Jun 2002

Biological Synopsis Of The Black Bream, Acanthopagrus Butcheri (Munro) (Teleostei: Sparidae) In Western Australia With Reference To Information From Other Southern States, Jeffrey V. Norriss, J E. Tregonning, Rod C J Lenanton, Gavin A. Sarre

Fisheries research reports

This synopsis presents a review of the literature and research to April 2001on the biology of black bream, Acanthopagrus butcheri (Sparidae), particularly in relation to Western Australian populations. A. butcheri is a commercially and recreationally important species, and is endemic to the coastal lakes, estuaries, river systems and sheltered coastal waters of southern Australia, including Tasmania. Separate stocks reside within each river/estuarine system in southwestern Australia, and there is considerable variation in feeding, growth rates and age at maturity among stocks. For rivers/estuaries that are seasonally flushed in winter, downstream movement with the flush is followed by the annual upstream …
