They totalize 90% of the catches of this family. The model of Schaefer is inapplicable to the pandora and bogue stocks and the author could not determine an optimal fishing effort for these two species. The important heterogeneity of size and equipment of the trawlers and the notable imprecision of the fishery statistics explain, perhaps, the inadequacies of this logistic model to this fishing. The author has defined the potentialities of the production of the pandora and bogue stock using the analytical model of Beverton and Holt. He verifies that an increase of the yield corresponds to a decrease of the fishing effort. The yield by recruit is proportionally better for the bogue than for the pandora; 75% against 50% of the maximal yield. This difference proceeds from the age of the first catch, higher for the bogue than for the pandora.
