| "The monterey sardine (Sardinops sagax) fishery of the Gulf of California was examined between 1972 and 1990. By analysing commercial catch-per-effort-unit data, we determined the density-dependence function of the Catchability coefficient to establish a potential relationship between this coefficient and relative population sizes. These were calculated by two methods, a new catchability deterministic method (CDM) and virtual population analysis (VPA). The inverse rclationship betwcen the catchability cocrficienl and fish density reponed for other purse seine fisheries is presented for the monterrey sardine fishery as well. The curves for both methods were similar, although the abundance determined for APV decreased after 1988/89 and for CDM decreased after 1986/87. Fishing mortality and abundance were determined for each class of length per season." | |
