In order to establish stock status, supply accurate advice and recommendations on management and monitor effectiveness of management intervention if need be, there is a need to develop procedures which

a) allow definition of the relationship between parent stock and recruitment levels in commercial prawn species, using fishery independant surveys as a means of determining recruitment levels

b) determine the status of these species and evaluate the potential risk of overfishing

c) develop methods which can used to evaluate the effectiveness of management intervention, if and when such intervention occurs.


1. To develop fishery independent sampling procedures that can be used as robust long term methods for monitoring recruitment levels in the tiger and endeavour prawn fisheries located along the northern Queensland east coast and in Torres Strait.
2. To obtain a series of (fishery dependent) indices of spawner biomass and (fishery independent) indices of recruitment which can be used to generate a long term data series.
3. Incorporation of the indices obtained in objective 2 into a stock - recruitment curve, an index of stock sustainability and an assessment of the risk of recruitment overfishing facing each of the species.
