          Abstract

          RESUMEN Scomberomorus sierra (sierra castilla) es una de las especies más importantes en la pesca artesanal del Pacífico de Colombia. Con el fin de investigar su biología reproductiva, insumo importante para la administración del recurso, se describió el desarrollo gonadal y se estimó la fecundidad parcial y el tamaño promedio de los ovocitos y la talla de madurez. Las muestras provinieron de faenas comerciales en diferentes zonas de pesca. De cada pez se obtuvo la longitud total (LT) y estándar (LS), así como el peso total y gonadal. La fecundidad se estimó combinando el método gravimétrico con análisis de imágenes, usando el software de libre acceso Image J®. Se colectaron 79 peces entre noviembre de 2013 y abril de 2014, con tallas entre 39.0 y 85.0 cm LT y peso entre 300 y 2850 g. La asignación de madurez gonadal se verificó histológicamente y se encontraron 75 hembras y 4 machos. A partir de la medición de 12084 oocitos se obtuvo un diámetro promedio de 0.551 ± 0.024 mm y valores de fecundidad variables con un ámbito entre 52398 y 480803 ovocitos/gónada. Microestructuralmente, se identificaron cuatro fases de desarrollo oocitario (perinuclear, alvéolo cortical, vitelogenado e hidratado) y en machos solo se observó un estado. El diámetro promedio de los oocitos en estado alvéolo cortical, vitelogénesis e hidratado fue de 168.75 ± 3.86 μm, 324.08 ± 5.89 μm y 388.90 ± 8.81 μm, respectivamente. La relación entre la fecundidad y las variables morfométricas del pez fue significativa y positiva, evidenciando que las hembras más grandes son las más fecundas. La talla de madurez sexual para hembras se estimó preliminarmente en 58.88 cm LT. Los resultados obtenidos son insumos de modelos pesqueros con aplicabilidad directa en medidas de manejo para S. sierra.

          ABSTRACT Scomberomorus sierra (Pacific sierra) is one of the most important species in the artisanal fishing on the Colombian Pacific. In order to investigate its reproductive biology, important input for fishery management, gonadal development was described and partial fecundity and average size of the oocytes were estimated. Fish samples came from commercial landings on different fishing grounds. Total (TL) and standard lengths of each fish were measured, as well as the total and gonadal weights. Fecundity was estimated using a gravimetric method combined with image analysis performed using the open access software Image J®. 79 fish were collected between November 2013 and April 2014, ranging from 39.0 to 85.0 cm in TL and weighing between 300 and 2850 g. The allocation of gonadal maturity was histologically verified, finding 75 females and 4 males. From the measurement of 12084 oocytes, an average diameter of 0.551 ± 0.024 mm was obtained, while fecundity varied between 52398 and 480803 oocytes per gonad. Microstructurally, four stages of oocyte development (perinuclear, cortical alveoli, vitellogenic and hydrated) were identified; only one state was observed in males. Mean diameter of the oocytes in the cortical alveoli, vitellogenesis and hydrated stages were 168.75 ± 3.86 |im, 324.08 ± 5.89 |im and 388.90 ± 8.81 |im, respectively. The relationship between fecundity and morphometric variables of the fish was significant and positive, evidencing that the largest females are the most fertile. Size at sexual maturity was preliminary estimated at 58.88 cm TL. The results obtained are inputs from fishery models with direct applicability to management of S. sierra.
