Resumen del producto

A bell shaped stock and recruitment curve was fitted to Flemish Cap cod data corres ponding to the period 1959-1977 and the derived curves of surviving stock, residual stock, equilibrium CPUE and equilibrium yield were obtained permitting us to examine the effects of changing exploitation rates. Two curves of sustainable catches were obtained one of them corresponding to the atable equilibrium points and the other to the unstable ones. Both curves have an important discontinuity at fishing mortality F=0.45 and for larger values ít is not possible to catch in equilibrium and a collapse can occur. The maximum sustainable yield is for F=0.35.
