Blue Warehou

Objectives

1. Determine the location and timing of spawning of blue warehou in the SEF area, and describe the relationship between spawning and the catching patterns of the trawl and gill net sectors of the fishery.
2. Estimate size/age at first sexual maturity and the sex ratios of spawning fish.
3. Describe gonad maturation cycles and the relationship between size/age and egg production (fecundity) in females.
4. Conduct per-recruit analyses to identify harvest strategies which allow optimum blue warehou egg production (and therefore recruitment).
