Aboriginal fishing strategy

The Western Australian Aboriginal Fishing Strategy (the “strategy”) was developed following a three-year consultative process overseen by former Western Australian Supreme Court Judge, the Hon E M Franklyn QC. Formulation of the draft strategy was assisted by a working group, which...

Identifying nursery areas used by inner bay and oceanic snapper stocks in the Shark Bay region, in relation to the effect of prawn trawling on inner bay snapper stocks

This study examined two aspects of the chemical composition of snapper otoliths from Shark Bay Western Australia as an aid to determining the spatial relationship among juveniles and to better understand the spatial relationships between juveniles and adults. Otoliths were collected from...

Biological and fisheries data for managing deep sea crabs in Western Australia

The crystal crab fishery on the west coast of Western Australia has only been commercially fished since the late 1990s. When this project was initiated in 2001, only compulsory monthly catch and effort data were being collected. This project has successfully set up the methods and means to collect...

Improved performance of marron using genetic and pond management strategies

Marron (Cherax tenuimanus) are the highest valued freshwater crayfish farmed in Australia. This project addressed the need to increase the profitability of commercial marron farms by improving growth rates and pond management strategies. The project evaluated progeny produced from wild populations...

Need

The management plan for the Houtman Abrolhos; system (Anon. 1998, section 10) identified a number of objectives. In essence these relate to understanding human-use impacts on the marine environment of the Abrolhos Islands and the evaluation of the effectiveness of present and future management strategies to ensure ecologically sustainable multiple use of Western Australia's first Fish Habitat Protection Area. Also it is important to recognise the more general responsibilities that the state of Western Australia will likely have with respect to the Commonwealth under its Oceans Policy statement and to the ongoing environmental stewardship considerations that the conferring of accreditation by the Marine Stewardship Council on the western rock lobster fishery entails.

Specifically, within the context of the Abrolhos Islands management plan there is a need to quantify the physical impacts of current human activity on Abrolhos marine habitats and subsequently establish a monitoring programme central to the ecologically sustainable management of this unique area. However, in order to determine such impacts and monitoring schemes, a number of preliminary steps need to be taken.

1) There is a need to collate, from diverse sources, existing research information relating to the ecology of the Abrolhos Islands, the effects of natural perturbations and to gather information on the types and effects of previous human use on Abrolhos marine habitats where it is documented. This synthesis of information will perform two functions: the first will be a statement of the current status of environmental impact research at the Abrolhos and the second will be as a background document for use in current deliberations and decision making by the Abrolhos Islands Management Advisory Committee.

2) A small amount of survey (field) work is required to establish precisely the timing and locations where commercial (potting, trawling, handlining, aquaculture) and recreational fishing and diving occurs particularly in relation to environmentally sensitive areas of the Abrolhos This information is not available from existing reporting systems such as log books etc. In addition some survey work is necessary to determine and provide general descriptions/ground truth of the various habitat/community types. The results from this field work will facilitate discussion on the scope of the issues to be assessed and methods to be used in long term monitoring programmes.

3) A workshop of community representatives and technical experts (representatives from AIMS, the universities, etc.) is needed to allow the formulation of a dedicated research/monitoring programme that will take into account issues raised by all stakeholders, and the legislated requirements of state and federal governments in relation to ecologically sustainable management.

Objectives

1. To collate existing research information relating to human use impacts and natural perturbations in Abrolhos marine habitats to provide a detailed overview of the status of current knowledge about the marine ecosystem of the Abrolhos Islands.
2. To conduct limited field work to determine the spatial and temporal distribution of commercial fishing and recreational activities and provide general descriptions/ground truthing of habitat/community types at the Abrolhos as baseline/background data for presentation at the workshop.
3. To conduct a scientific workshop including community representatives and technical experts to determine the objectives and formulate a dedicated research programme to provide quantitative monitoring data for use in the sustainable management of the Abrolhos Islands Fish Habitat Protection Area.

Quantification of changes in recreational catch and effort on inner Shark Bay snapper species following implementation of responsive management measures

A 12-month creel survey of recreational boat-based fishing in Shark Bay, Western Australia was conducted between May 2001 and April 2002 to estimate the catch of pink snapper. During the survey 431 boat crews were interviewed at public boat ramps of which 414 had been fishing. The information...
