Abstract
CPUE indices from the SNA 7 trawl fishery are updated and refined. The CPUE indices exhibit a very strong increase over the last 5 years. The increase in CPUE is consistent with a recent period of strong recruitment evident from the recent increase in the proportion of smaller fish in catch from the trawl fishery. However, preliminary population modelling of the SNA 7 fishstock indicates that the magnitude of the recent increase in CPUE indices is inconsistent with the historical stock dynamics.
