Resumen
Un total de 1899 muestras de merluza (Merluccius gayi) de la pesca artesanal utilizando como arte de pesca el espinel de fondo, colectadas durante el año 2014, en Anconcito, provincia de Santa Elena. Las muestras fueron clasificadas entre 630 machos (33.25%) y 1.269 hembras (66.75%) lo cual indico que hubo mayor presencia de hembra a relación de machos esto se evidenció con los resultados de la proporción sexual (1:2,01). En la composición de la captura de fauna asociada Prionotus stephanophrys fue la especie que mayor porcentaje presentó (79,7 %). Se estableció que los estadios de madurez sexual de las muestras de Merluccius gayi analizadas, presentaron los estadios III y V la mayor dominancia en el estudio. La talla media de madurez sexual de la población de Merluccius gayi analizada quedó determinada en 31 cm de Lt. La información resultante recomienda que se realice un seguimiento biológico pesquero al recurso estudiado y que esta información permita constituir un adecuado manejo del mismo.
A total of 1899 samples of hake (Merluccius gayi) in the artisanal fishery using as a fishing gear the bottom spinel, collected during 2014, in Anconcito, province of Santa Elena. The samples were classified among 630 males (33.25%) and 1269 females (66.75%), which indicated that there was a greater presence of females than males, evidenced in the results of the sexual proportion that was (1: 2.01). In the composition of the associated fauna catch Prionotus stephanophrys was the species with the highest percentage with a total of (79.7%). It was established that the stages of sexual maturity of the samples of Merluccius gayi analyzed, showed stage III and V the highest dominance in the study. The average length of maturity of the population of Merluccius gayi analyzed was determined at 31 cm of Lt. The resulting information suggests that a biological fishing follow-up to this resource be carried out to establish an adequate management of the same.
