| description | Age, growth, and the length-weight relationship were estimated for the Pacific golden-eye tilefish Caulolatilus affinis captured by the artisanal fishery in the central region of the Gulf of California. The size and weight structure differed between sexes, males being larger and heavier than females; however, differences in the length-weight relationship were not detected and the slope value (b = 2.66) showed that it was a negative allometric relationship. The youngest and oldest organisms were 3 and 21 years old, respectively. The age structure showed differences between sexes, males being more abundant at older ages and females at younger ones. The dominant age group for females was 11 years old and for males, 16 years old. The von Bertalanffy growth model fitted adequately the mean size and age data; the model parameters were L∞ = 432.32 mm total length, k = 0.232 mm yr–1, and t0 = 0.164 yr for males, and L∞ = 422.99 mm total length, k = 0.245 mm yr–1, and t0 = –0.095 yr for females. Differences in individual growth and growth rate between males and females were not detected. According to the age structure and growth pattern, C. affinis is a slow-growing, medium-lived species. Our results suggest that C. affinis is underexploited in the central Gulf of California because it is a non-target species.
Se estimó la edad, el crecimiento y la relación longitud-peso del conejo Caulolatilus affinis capturado por la pesca artesanal en la región central del Golfo de California. La estructura de tallas y pesos fue diferente entre sexos, siendo los machos más grandes y más pesados que las hembras; sin embargo, no se detectaron diferencias en la relación longitud-peso y el valor de la pendiente (b = 2.66) indicó que ésta es una relación alométrica negativa. Los organismos más jóvenes y más grandes fueron de 3 y 21 años, respectivamente. Se detectaron diferencias en la estructura de edad entre sexos, siendo los machos más abundantes a edades mayores y las hembras a edades menores. El grupo de edad dominante para las hembras fue de 11 años, mientras que para los machos fue de 16 años. El modelo de crecimiento de von Bertalanffy se ajustó adecuadamente a los datos de talla promedio a la edad; los parámetros del modelo para los machos fueron L∞ = 432.32 mm longitud total, k = 0.232 mm año–1 y t0 = 0.164 año, y para las hembras, L∞ = 422.99 mm longitud total, k = 0.245 mm año–1 y t0 = –0.095 año. No se detectaron diferencias en el crecimiento individual, ni en la tasa de crecimiento entre machos y hembras. Según la estructura de edades y el patrón de crecimiento, C. affinis es una especie de crecimiento lento y longevidad media. Los resultados obtenidos sugieren que C. affinis se encuentra subexplotado en la región central de Golfo de California debido a que no es una especie objetivo. |
