Abstract

Objective
1. Measure spatial and temporal trawl frequency of scallop grounds using VMS data. This will provide a relative measure of how often individual undersized scallops are caught and put through a tumbler
2. Estimate discard mortality and growth rates for saucer scallops using cage experiments.
3. Evaluate the current management measures, in particular the seasonal closure, rotational closure and seasonally varying minimum legal sizes using stock assessment and management modeling models. Recommend optimal range of management measures to ensure long-term viability and value of the Scallop fishery based on a formal management strategy evaluation.

Outcomes acheived to date:
1. Improved understanding of the survival rates of discarded sub-legal scallops;
2. Preliminary von Bertalanffy growth parameters using data from tagged-and-released scallops;
3. Changing trends in vessels and fishing gear used in the Queensland scallop fishery and their effect on scallop catch rates over time using standardised catch rates quantified;
4. Increases in fishing power of vessels operating in the Queensland scallop fishery quantified;
5. Trawl intensity mapped and quantified for all Scallop Replenishment Areas;
6. Harvest Strategy Evaluations completed.
