Accurate and precise estimates of spawning biomass are needed to underpin sustainable management of Australia's largest fishery, the SASF. Estimates of mean daily egg production that underpin application of the DEPM need to be as accurate and precise as possible. A new sampling technique that provides more precise estimates of mean egg density is needed to refine estimates of mean daily egg production. The benefits/costs of using the new sampler need to be validated before it can be used to underpin future management of the SA Sardine Fishery.


1. To improve the accuracy and precision of estimates of spawning biomass obtained using the Daily Egg Production Method.
