520 |a"In this year's assessment, a new catch-per-unit effort series was developed that combined data for Canadian otter trawls and Spanish pair trawls and a new method described in Schnute (1977) was used to derive the equilibrium Shaefer curve. This stock remains in a critical state and the recruitment relationship derived below implies that recovery may be slow. For 1977, 10,600 mt were caught, over 50% over quota. The catch per-unit-effort was quite high but the fishery has changed a great deal and thus this figure may not be consistent with past figures. Optimism derived from this piece of data could not be supported by the rest of the analysis"--Introduction.
