Northern Territory strategic plan for fisheries research and development 2002 to 2006

Since publication of the original Plan in early 1999 there have been significant changes in NT Government directions and priorities that required the Plan be updated. These included: Greater emphasis on recreational fishing; Increased prominence being given to aquaculture development, both...

Development of commercial production systems for mud crab (Scylla serrata) aquaculture in Australia: hatchery & nursery

Commercially viable techniques for rearing Scylla serrata larvae through to megalops stage have been developed at both the centres involved in the project, the Darwin Aquaculture Centre (DAC) and the Bribie Island Aquaculture Research Centre (BIARC). The methods developed in an earlier ACIAR project...

Towards a national strategy for mud crab research - mud crab workshop

A workshop was held in Darwin, the Northern Territory (NT) in May 1999, to develop a National Strategy for Research on Mud Crab ( Scylla sp.) in Australia. Fisheries managers and researchers from Western Australia, the NT and Queensland attended, along with Industry representatives from the NT. The...

Methods for monitoring abundance and habitat for northern Australian mud crab Scylla serrata

A significant achievement of this project has been the completion of mapping of coastal wetland habitats using remote sensing techniques, which provided a complete broad-scale coverage of mud crab habitats in the NT and Qld. A major outcome/output of this work has been the incorporation of the...

Need

In October 1998, key demersal fishers and NT Fisheries Division officers held a meeting to review the current knowledge and understanding of the Demersal Fishery and the areas of knowledge that are still required to assure its viable development. Participants identified two impediments to the expansion of the demersal fishery:

1. the inability to consistently supply fish to the market; and
2. catching fish at a profitable rate.

The variation in catch rates are substantial enough make the difference between profit and significant loss. Sensitivity analysis on projected catch rates and cost structures support the view that there is potential to achieve an adequate, if not attractive, level of profitability in the fishery with passive fishing methods (Cann, 1996). This work has shown that profitability is quite sensitive to catch rates and market prices, with a marginal increase in either prices or landings, making the difference between a profitable or uneconomical fishing operation.

There is no long-term trend apparent in the CPUE data, and fishers have presented a number of reasons why both seasonal and inter-annual catch rates are so variable. These include water temperature changes in concert with El Nino events, seismic surveys conducted by oil exploration companies and limited experimentation with a wider range of gear types. Further, there are other factors, which may affect profitability such as vessels used, operating costs, debt structure and training/skill of industry members. The meeting agreed that these and other issues must be formally addressed if the fishery is to develop further. It also identified a number of specific research projects (see B14).

Industry and government agreed that the best way address issues affecting profitability would be to employ relevant specialists to participate in a workshop with industry, researchers and managers. This was seen as the most effective way to exchange ideas, share experience, reach agreement on how to best improve profitability and identify what research is needed to improve industry viability.

Objectives

1. To examine factors affecting profitability in the Demersal Fishery
2. To increase industry awareness about how profitability in fishing operations may be improved
and
3. Determine and prioritise the principal areas for further research.
