Brief description

The sandfish on Warrior Reef were surveyed at 50 sites from 14 to 17 January 1998. This showed that the abundance of Holothuria scabra (sandfish) on Warrior Reef in January 1998 was between 63% and 86% (95% CI, mean 77.5%) smaller than in November 1995. The H. scabra stock in November 1995 was considered as over-exploited, therefore this reduction indicates a serious depletion. Both the fishery (2+ years old) and recruiting (one year old) year-classes are depleted, the latter the result of a depleted breeding population, indicating a direct stock-recruitment relationship for H. scabra on Warrior Reef. This indicates that the fishery stock is in a downward spiral, with progressively smaller breeding populations leading to smaller and smaller recruitments. Severe management measures are required to avoid a total collapse of the stock.

Notes

Credit
The Queensland Fish Management Authority (QFMA) initiated this project. Environment Australia provided a valuable contribution towards funding the project with the QFMA meeting the remaining costs. The project would not have been possible without the assistance of officers from the following agencies: Queensland Boating and Fisheries Patrol (QB&FP), Australian Customs Service (ACS) and the Australian Fisheries Management Authority (AFMA). Personal thanks for assistance beyond the call of duty go to Mr Bruce Kingdom (QB&FP), Mr Mick Bishop (AFMA), Sgnt Robbie Graham (Queensland Water Police), and the captain and crew of the patrol vessel 'WAURI'.
