Validation and extension of acoustic reef habitat mapping methodologies in the western abalone zone, Victoria

Acoustic reef mapping to support abalone fisheries assessment is presently being undertaken by the Tasmanian Aquaculture and Fisheries Institute (FRDC 2003/050) in key commercial fishing grounds. The TAFI SEAMAP program has developed reef mapping techniques with acoustic sounders and underwater...

Bringing economic analysis and stock assessment together in the NPF: a framework for a biological and economically sustainable fishery

The effort reductions in the NPF (instituted during the 2001 NORMAC meeting after an international review of the stock assessment for tiger prawns) were implemented based on combinations of gear and season reductions. Given the slow recovery of the tiger prawn stocks in certain parts of the Gulf,...

Variation in banana prawn catches at Weipa: a comprehensive regional study

Until the late 1990s, the Weipa and Karumba regions were the most important areas for banana prawn fishing in the Northern Prawn Fishery, both having a similar long-term average annual catches of about 800 tonnes, with a value of over $12 million. However, since 1998, in each of 4 consecutive...

Development of an individual transferable catch quota model for the Coral Reef Fin Fish Fishery of the Great Barrier Reef

Fishing is the major extractive resource use on the Great Barrier Reef (GBR), where the annual economic value of the commercial Coral Reef Fin Fish Fishery is about AU$60-100 million. Each year the commercial line sector harvests between 3000-4000 t from the multi-species reef line fishery, while...

Determining appropriate sizes at harvest for species shared by the commercial trap and recreational fisheries in New South Wales

There is concern that many species harvested by the NSW demersal trap and offshore recreational fisheries are in decline and there exists very little biological information on which to assess their stock status or base management decisions. The NSW demersal trap fishery, worth around $4 million a...

Spatial modelling and assessment of the Victorian southern rock lobster (Jasus edwardsii) fishery

The formal assessment program for Victoria’s southern rock lobster fishery commenced in 1993 (FRDC 92/104). Initial focus of the study was to establish long-term monitoring programs and to analyse existing historical commercial catch data. This study advanced the knowledge of the state of the...

Evaluation of egg production as a method of estimating spawning biomass of redbait off the east coast of Tasmania

FISHERY SYNTHESIS A major purse seine fishery for small pelagics developed off Tasmania in the mid-1980s, with catches peaking at over 40,000 t in the late 1980s (Pullen 1994a). The fishery was based on surface schooling jack mackerel (Trachurus declivis) with catches that were prone to large...

Determination of a cost effective methodology for ongoing age monitoring needed for the management of finfish fisheries in Western Australia

Ongoing monitoring and assessments of the status of the fish stocks of WA is a necessary step to implement Ecologically Sustainable Development (ESD) for fisheries within Western Australia (Fletcher, 2002). Moreover, this was one of the main recommendations identified in the “Toohey Report”...

Relationships between fish faunas and habitat type in south-western Australian estuaries

Estuaries provide crucial habitats for numerous commercially and recreationally important fish species (Haedrich 1983, Potter et al. 1990, Elliot and Dewailly 1995, Valesini et al. 1997). Some marine species use estuaries either as a nursery area or for more protracted periods, while other species...

The effects of western rock lobster fishing on the deepwater ecosystems off the west coast of Western Australia

In 1999/2000 the Western Rock Lobster Managed Fishery became the world’s first fishery to receive Marine Stewardship Council (MSC) certification, and since then the management process has moved on to address the MSC’s annual audit requirements. As part of this process an ecological risk assessment ...
