Incomplete contents:
The biomass of smooth oreo in OEO 3A was estimated from a stock reduction analysis that used abundance indices from catch per effort (CPUE), and research trawl survey data. The analysis suggests that the original smooth oreo stock size in the main fishing ground of OEO 3A was small. Yields from the fishery will probably be low because the productivity of smooth oreo based on unvalidated age estimates is likely to be low. The maximum likelihood estimate of long-term yield for smooth oreo in OEO 3A is 1000 t. The recent catch levels of smooth oreo from OEO 3A are higher than the long term sustainable yield. (auths.)
