Abstract

General aspects of the Peruvian anchoveta north-center stock, from 1961 to 1999 are presented. A Virtual Population Analysis (VPA) has been applied, using fishery-biological information, from the hydroacoustic surveys carried out by IMARPE and from the industrial purse seine fleet operations. Natural mortality rates (M, from 1,0 to 0,75) were used; and, in order to syntonize the process, effort and catches data based on gross registration tonnage by trip (GRT-trip) were considered. We can conclude that in the anchovy north-center stock fishery exists an effort-catches relationship.
