In the framework of the methods introduced in the first part of this work and considering the fishing effort as the control variable, we introduce a direct procedure to estimate an upper bound for its admisibility set that ensures a viability condition for the exploited biomass. Using the catch per unit effort as an abundance index we develop dynamic regression schemes for the Gompertz-Fox production model. Our theoretical results were applied to the study of the optimality of the fishing effort in two fisheries were Mexican vessels performed the dominant catch; the northen anchovy, and the Pacific sardine in the Gulf of Galifornia.
