Reporte del estudio de la pesca acompañante del camarón para el Golfo de Guayaquil, para los meses de mayo, junio y julio de 1986. Se dan a conocer las diferentes familias y/o especies para las categorías camarón, pescado bueno y basura; con sus respectivas tasas de captura y porcentajes de ocurrencia. La razón fue 1:2.18:13.84 kg.h-1 variando 1:2.75:12.60 kg.h-1 determinándose que entre 13%-17% es aprovechado para consumo humano directo y entre 77%-81% es aprovechado. Hipotéticamente se calculó para el total de la flota camaronera (240 barcos), que apróximadamente de 11,000 y 36,000 t son aprovechadas anualmente y entre 70,000 y 190,000 t son devueltas al mar. |

The stock estimates obtained during the demersal fish resources survey in 1980-1985 were used to estimate the potential yields of demersal stocks of the Ecuadorian Continental Shelf. The difficulties of predicting yields for multispecies fisheries are discussed and modified version of the Gulland model was adopted. The potential realizable yields for multispecies fisheries are discussed and a modified version of the Gulland model was adopted. The potential realizable yield was calculated to be between 15,000 t and 20,000 t per year, of which 2,000 t is good quality fish, 5,000 t per year of small and medium fish and 8,000 t of gurnards. The majority of these resources are at present being fished at around their optimum levels and any further developments... |
