Resumen del producto

The objective of fisheries management is to maintain the biomass of fish stocks to levels that can produce the maximum sustainable yield (MSY). However, periodic assessments of the biomass of the populations are not currently common. In the present study we used the method of Martell & Froese (2013) to estimate the MSY of the sardina monterrey stock on the west coast of Baja California. Catch-data recorded for the period 1980-2013, and the value of resilience (r) were used for the species. With the results of the model performance, the catch at maximum sustainable yield (CMSY ) was 138,147 t and the 95% confidence interval between 102,338-186,486 t; the carrying capacity K=1,043,483 t (515,515 t < K < 2,112,172 t); intrinsic population growth rate r=0.530 years·1 (0.222 years' 1 < r < 1.260 years.l) and biomass at MSY (BMSy )=521,742 t (257,758 t < BRMs < 1,056,086 t). Moreover, the response of the population to different scenarios of fishing pressure as man agement measures, through an exercise with three potential scenarios of biomass was evaluated: Keep biomass aboye MSY, lower MSY and at risk of collapse. In order to assess changes in population biomass at different levels of fishing.
