1. Need to evaluate current management measures

There is a need to evaluate the current management measures applied to the scallop fishery, particularly the range of minimum legal sizes, the effects of the southern closure and the rotational closures. Precisely what are these measures achieving and are they effective? Can the value of the resource be increased with alternative management measures, within the constraints of acceptable risks of overfishing? One of QFIRAC's priorities is to look at the scallop fishery and in particular the value of protected areas, sources of mortality and stock structure.

2. Need to determine discard mortality and growth by region

Some processors are requesting DPI&F abandon the rotational spawning stock closures and lower the minimum legal size of scallops with the intention of increasing the amount of scallops fishers can retain and market. To consider any of these changes in management that could possibly lead to overfishing it is imperative that we have precise estimates of key stock assessment parameters including gear selectivity, and discard mortality.

3. Need to measure fine-scale trawl intensity

The frequency with which discarded scallops are recaptured over time and space may impact on estimates of discard mortality. Using the VMS trawl track database the frequency with which an area is trawled will be determined to guide subsequent discard mortality experiments.
