Resumen del producto

Eight important fisheries (sardine, three shrimps, yellow fin tuna, skip jack tuna, big eye tuna, and the Caribbean lobster) were evaluated and a meta data analysis was carried-on. Each fishery was analysed based on catch data, the population parameter values, and on its main socio-economic attributes. Each population was assessed reconstructing the age structure of each stock, then the profits, direct jobs, and the profits per fisher were estimated under different ages of first catch (tc). From here, values related to the maximum sustainable yield (FMSY) and the maximum economic yield (FMEY) were selected as optimum harvesting options. Results show that the yield increases with tc and those at the FMSY level are higher than at the FMEY. The profits are higher at high tc values, being more profitable under the FMEY levels. The social value, as profits/fisher, is higher on applying the FMEY strategy.
