Risk Assessment Of The Potential Impacts Of Seismic Air Gun Surveys On Marine Finfish And Invertebrates In Western Australia, F J. Webster, Brent S. Wise, H Kemps, Warrick Fletcher

Fisheries Research Reports

Seismic surveys have the potential to affect marine life, including commercially and recreationally important finfish and invertebrate species and their prey. There is, however, considerable uncertainty around the degree of impact and relevant pressure-response pathways across the different taxonomic groups.

Geography And Island Geomorphology Shape Fish Assemblage Structure On Isolated Coral Reef Systems, Scott Bennett, Andrew R. Halford, Howard Choat, Jean-Paul A. Hobbs, Julia Santana-Garcon, Anthony M. Ayling, Euan S. Harvey, Stephen J. Newman

Fisheries Research Articles

We quantify the relative importance of multi-scale drivers of reef fish assemblage structure on isolated coral reefs at the intersection of the Indian and Indo-Pacific biogeographical provinces. Large (>30 cm), functionally-important and commonly targeted species of fish, were surveyed on the outer reef crest/front at 38 coral reef sites spread across three oceanic coral reef systems (i.e. Christmas Island, Cocos (Keeling) Islands and the Rowley Shoals), in the tropical Indian Ocean (c. 1.126 x 106 km2). The effects of coral cover, exposure, fishing pressure, lagoon size and geographical context, on observed patterns of fish assemblage structure were …

This project took advantage of an unprecedented deployment of acoustic receiver infrastructure around the Western Australian coast to monitor a large number of sharks implanted with acoustic tags. This research was undertaken to better understand the temporal and spatial dynamics of commercially-important sharks in Western Australia, which has enabled a re-evaluation of the risks of cryptic sources of catch and bycatch to dusky and sandbar shark stocks and development of population simulation models with which to test the implications of spatially-different histories of fishery management, as well as future spatial-management arrangements for whiskery and gummy sharks stocks.

WA Marine Stewardship Council report series

The western rock lobster Panulirus cygnus (George) is taken by commercial and recreational fishers throughout its geographic range along the lower west coast of Western Australia. The main commercial fishery for P. cygnus is the West Coast Rock Lobster Managed Fishery (WCRLMF), which is Australia’s largest single-species fishery, currently worth about $400 million annually. Western rock lobster provides the basis for the economies of a number of coastal towns and also supports a recreational fishery.

White Shark Research Report Q And A - Based On Fisheries Research Report 273: Evaluation Of Passive Acoustic Telemetry Approaches For Monitoring And Mitigating Shark Hazards Off The Coast Of Western Australia, Department Of Fisheries, Western Australia

Fisheries Research Reports

This document is a Question and Answer summary based on Fisheries Research Report 273: Evaluation of passive acoustic telemetry approaches for monitoring and mitigating shark hazards off the coast of Western Australia.

Shark attacks are rare but traumatic events that involve complex and dynamic interactions between sharks’ ecology and human demographics and behaviours. To better understand the biological and ecological factors contributing to the series of incidents of white shark (Carcharodon carcharias) attacks off Western Australia, sharks were fitted with acoustic transmitters (‘tags’) that emit unique identification codes every 50 to 150 seconds. Tagged sharks were monitored by up to …

Innovative Development Of The Octopus (Cf) Tetricus Fishery In Western Australia, Anthony M. Hart, Stephen C. Leporati, Ross Marriott, D. V. Murphy

Fisheries Research Reports

In 2010 the broad-scale introduction of a new gear type, the trigger trap, saw a 260% (33 t in 2009 to 119 t in 2010) increase in octopus landings in the Western Australian Developmental Octopus Fishery (DOF). Deployed in waters previously unfished by the DOF, initial catches demonstrated that trigger traps were more efficient and captured a different component of the population, compared to open-ended shelter pots traditionally used in the fishery. This shift caused a surge of interest in commercial octopus fishing.

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.

2. Examine the effectiveness of potential gear modifications to the float rigs of fishing pots/traps to reduce their likelihood of entangling whales.

Seasonal Wind Patterns Around The Western Australian Coastline And Their Application In Fisheries Analysis, Alan Pearce, Anthony M. Hart, D. V. Murphy, Hannah Rice

Fisheries Research Reports

Monthly wind statistics have been derived for 23 weather stations along the Western Australian coast from Wyndham in the north-east of the state, down the west coast and around to Eucla in the south-east. The overall seasonal wind cycle at each site has been derived based on the 30-year period 1982 to 2011 (although a few stations had shorter records), and these show the major changes between the wind regimes along the Northwest Shelf, the west coast and the south coast.
