Análisis de la estructura de tallas y la relación peso-longitud del Dorado (Coryphaena hippurus) capturado en Mazatlan Sinaloa, México

Abstract

En el sur del Golfo de California, en el Puerto de Mazatlán, Sinaloa, el dorado(Coryphaena hippurus) soporta una pesquería artesanal y deportiva de gran importancia. Sin embargo, los estudios biológico-pesqueros para esta área son muy escasos. Durante el periodo de julio de 2000 a diciembre de 2001 se realizaron muestreos biológicos mensuales en las flotas deportiva y artesanal. Se encontró un intervalo de tallas de 47 a 164 cm de longitud furcal (LF) para la flota deportiva y para la flota artesanal de 38 a 137 cm LF. En promedio la captura en ambas flotas se sostiene por organismos entre 55 y 100 cm LF. El crecimiento del total de los organismos muestreados en ambas flotas fue alométrico. El resultado de la prueba T2 Hotelling demostró que existen diferencias significativas en el parámetro (b) entre machos y hembras. Tanto en las tallas como en el peso promedio por estación y por sexo se encontraron diferencias significativas. Se hizo una estimación indirecta de la edad usando el método Bhattacharya determinando 4 grupos de edad para los machos y 3 para las hembras.

The southern of the Gulf of California, specifically off Mazatlan, Sinaloa, México supports an important sport and artisanal fishery of Dolphinfish Coryphaena hippurus, however studies of the biological and fishing aspects for this area are scarce. We sampled monthly biological samplings from the sport and artisanal fleets from July 2000 to December 2001. Sizes from 47 to 164 cm fork length (FL) in the sport fleet and 38 to 137 FL in the artisanal fleet were found. The average catch in both fleets was fish from 55 to 100 FL. The growth of the organisms sampled from both fleets was allometric. The Hotelling's T2 test showed significant differences in the growth parameter "b" between males and females. Significant differences were found in the average sizes and weight by season and sexes. Four age groups were estimated for the males and three for females, using the Bhattacharya method.
