Contribución al conocimiento de la biología de la sardina de Galicia

Abstract

En el período de 1980 a 1982, se realizaron en el Laboratorio de Vigo 53 muestreos biológicos de sardina y una campaña de investigación acústica, examinándose un total de 4368 ejemplares. Con los datos obtenidos se calculó la talla de primera maduración con valores de 14.5 cm para las hembras, 14 cm para los machos y 14.5 cm el valor de ambos sexos. La edad de primera maduración se sitúa en 1.3 años. La época de puesta es amplia, abarcando de diciembre a mayo con un período de reposo total de junio a septiembre. La proporción de sexos se sitúa alrededor del 50% a lo largo de los tres años. Aparecen variaciones en el porcentaje de hembras por edad en los individuos adultos. Se calculó la relación talla/peso para valores de peso vivo y peso eviscerado.

During the period 1980-1982 a total of 4368 individuals of pilchard coming from 53 biological samples and acoustic survey were examined. It was calculated the first maturity length with values of 14.5 cm for females, 14 cm for males and 14.5 cm for both sexes. The corresponding age is 1.3 years. The spawning season is rather wide, from December to May with a clear resting period between June and September. The sex ratio is quite constant, 1: 1, along the three years of the study. There are some variations in the porcentage of females by age in the adults age groups. The lenght/weight relationship for gutted and ungutted pilchard were also calculated.
