The evaluation of optimus mesh size for multispecies trawl fisheries relies primarily on the aggregation of individual yield-per-recruit response surfaces. The analytic model expression incorporated in these procedures assumes knife-edge selection. The present study examines the effect of replacing the usual knife-edge selection assumption with empirically-based sigmoid selection in the evaluation of the optimum mesh size for the Samar Sea multispecies demersal trawl fishery.
