Enhancement of ship-board survivorship of coral trout destined for the live fish market
The live Coral Trout fishery is currently conservatively valued at $3.5 million. Demand for live Coral Trout is not being met and it is clear that the market could accept additional product. Anecdotal information also indicates that competing countries supplying the 14000T live tropical fish market in Hong Kong are suffering from over-fishing and demand is expected to further increase as a result.
A major limitation preventing the live Coral Trout industry expanding to fill the available market is the mortality due to injury and disease. Although developments in technology and skill level have occurred in the last 12 months, these developments are not industry wide and are generally specific to particular (eg very large) vessels. Most boats are presently restricted to a maximum of 5 to 6 days at sea as they are unable to hold the fish live for longer. In addition, although mortality of live fish may be as low as 2% from processor to market, mortality between capture and transfer to processors may reach 50% at some times of the year. Whilst current practice means that fish showing imminent sign of death are sacrificed to obtain fillet, this results in significant devaluing of the product. This leakage of product from the high value live market (@ $35+/kg) to the fillet market (+ $14+/kg) results in significant loss of value in this fishery with loss of income to all sectors of the industry.
The adoption of strategies to target the live trout, rather than the fresh frozen fillet, market also results in reduced total catch per boat due to the significant price advantage and larger on-board facilities required to hold the product. By providing information that will allow a code of practice to achieve World Best Practice, information that is not currently available for coral trout, this project that will facilitate the movement of boats into the live fishery. It is likely that the total catch will be reduced and the long-term sustainability of the fishery will be enhanced.
Final report
Towards evaluating the socio-economic impacts of changes to Queensland’s inshore fishery management
Previous changes in fisheries management have had significant socio-economic impacts on Queensland fisheries (and likely on local seafood supply). E.g. the implementation of the RAP and GBRCMP implemented by the GBRMPA and EPA respectively in 2004 has resulted in over $80 million compensation being paid to fishers and related businesses to date. A more accurate measure of the extent of socio-economic impacts of the RAP is unavailable, however, due to the lack of established methodologies to monitor such changes, and lack of baseline socio-economic data prior to implementation of the RAP.
Management changes are planned for the near future for Queensland’s inshore fisheries in the form of a new ECIFF Management Plan, potential regional-based management (e.g. area closures), and a management plan for mud crab. Relevant fisheries stakeholders (QSIA and Sunfish) and managers (DPI&F) have expressed the need to collect baseline data prior to management change and to develop and implement methodologies that will allow monitoring of socio-economic changes following the implementation of these management initiatives. Such a methodology will involve selecting appropriate indicators of the socio-economic environment and the collection of baseline data outlining the current socio-economic trends for the recreational, charter and commercial inshore fisheries and seafood consumers. In addition, efficient methodology with which to undertake long-term monitoring of the appropriate socio-economic indicators needs to be determined. This research is also needed if appropriate and useful socio-economic indicators are to be included in a PMS for the inshore fishery. The proposed project will fulfil these needs, allowing the effects of changes in inshore fisheries management to be assessed in the future. Provision of baseline data will also assist in the implementation of any future management change, such as regional-based management and management plans for the mud crab fishery (which is not included in the ECIFF Management Plan).
