Funded Activity Summary

There is an urgent need to provide basic information to assist management of beche-de-mer fishery in Queenslands GBR and to determine sustainable harvest levels. The proposed research directly addresses two of the highest priority research topics for harvest fisheries outlined by QFMA (Research needs and priorities for the management of Queensland’s fisheries, QFMA, 1997, p 16), which are

· to estimate of standing stocks of beche-de-mer (holothurians) off the east coast

· to determine sustainable annual harvest levels of beche-de-mer off the east coast

The project also addresses the lower priority research topic

· to determine the ecology of the major beche-de-mer species (black teatfish)

Objectives:
1. To develop a survey methodology applicable for all shallow water beche-de-mer species.
2. To adapt established techniques for enzyme electrophoretic analyses of holothurians to several beche-de-mer species.
3. To determine the stock size of beche-de-mer over a large geographic area in the GBR.
4. To determine the stock size and biomass of the black teatfish over a large geographic area in the GBR.
5. To establish the period of reproduction of the black teatfish on the GBR.
6. To measure dispersal and recruitment in black teatfish using genetic markers.
7. To identify and report the implications of these findings for management of beche-de-mer fisheries.
8. To measure the recovery time for overfished black teatfish stocks (numbers and biomass)
9. To assess the likely source of recruits to recovering populations, including the role of protected reefs.
10. To estimate growth rates for black teatfish.
11. To describe large scale geneflow and dispersal of sandfish among fished populations in NT and WA.
