Development of a 5-year sector and NT Strategic Research, Development and Extension (RD&E) Plan for Northern Territory fisheries and aquaculture based on priority needs of major stakeholder sectors

The Fisheries Research and Development Corporation’s (FRDC) Northern Territory Research Advisory Committee (NT RAC) recognised that a 5-year Research Development and Extension (RD&E) Plan was a major strategic need of the NT but acknowledged that there was limited capacity among sectors to...

Tactical Research Fund: Developing a management framework and harvest strategies for small scale multi-species, multi-method community based fisheries, using the South Australian Lakes and Coorong Fishery as a case study

The commercial Lakes and Coorong Fishery (LCF) operates at the end of the Murray-Darling Basin where the river system meets the Southern Ocean, encompassing a diverse range of freshwater, estuarine and marine habitats and communities. This multi-gear fishery targets a range of species...

Catch and effort data obtained from commercial logbooks is the primary source of information used as an index of abundance for most SESSF species. The assumption underlying this is that commercial catch rates change in a linear fashion with abundance. This assumption, however, has little independent support for many SEF species and is frequently criticised by industry and scientists alike. One of the most significant problems with commercial CPUE data in the SEF is that fishers modify their fishing practices to suit quota availability and market demands. Also, many fishermen only put the retained catch in logbook data, not the total catch. Furthermore, the influence of environmental conditions on fish availability also reduces the effectiveness of CPUE as an index of abundance. Low or bycatch TACs also prevent catch rate data being used as an index of abundance.

Implementation of a fishery independent survey is the most cost-effective and feasible means to get an independent index of abundance for the suite of SESSF species.

Recognising this, the SESS Fishery Assessment Group (SESSFAG) has placed highest priority on the need to implement fishery-independent methods for surveying relative abundance of SESSF fish stocks.

Objectives

1. Review the current fishery independent surveys that are operating in the SESSF and determine their efficacy and potential for use in a multi-species survey. Determine which survey methods are most suitable for the main species in the SESSF.
2. Design a suite of cost-efficient fishery independent surveys that will meet the needs of the fishery in providing indices of abundance for most major species in the SESSF. Determine the most practical way of undertaking the surveys and gain broad stakeholder acceptance of the survey design.
3. Determine the cost structure for the surveys and how funding and research quota will be allocated.
4. Undertake a full one-year trial of the survey design. Review the results of the survey with respect to cost-efficiency, practicality and provision of high quality (precise) indices of abundance and modify the design accordingly.
5. Implement a long-term (5-10 year) survey program that can be progressively funded by industry under standard CRIS Policy
