Desarrollo gonadal y ciclo reproductivo de Lutjanus peru (Pisces: Lutjanidae) en Guerrero, México

Abstract

En este trabajo se describen aspectos de la biología reproductiva de Lutjanus peru que se pueden usar para el manejo de su pesquería. Se realizaron recolectas, mensualmente durante 1993 y 1994, a partir de las capturas comerciales del litoral sur de Guerrero, México. Se encontró una proporción sexual global de 1:1.37 (M:H); sin embargo la proporción sexual de cada mes fue muy variable. Se analizó el factor de condición y los índices de repleción gástrica, hepatosomático y gonadosomático. Ninguno de los índices morfofisiológicos mostró tendencias claras. A partir de 377 gónadas, tanto de machos como de hembras, se caracterizaron histológicamente cinco estadios de desarrollo gonádico en cada sexo. L. peru presenta desarrollo gonadal asincrónico y desoves múltiples. Se observaron dos períodos de desove en 1993 (marzo y agosto-septiembre) y tres en 1994 (abril-mayo, julio-agosto y noviembre), con máximos en agosto de ambos años. La talla de primera madurez de las hembras de L. peru se estimó en 295 mm de longitud furcal

In this paper, aspects of the reproductive biology of Lutjanus peru that can be used for the fishery management are described. Samples were taken monthly in 1993 and 1994, from commercial catches in the southern coast of Guerrero, Mexico. A global sex ratio of 1:1.37 (M:F) was found, but the sex ratio was highly variable each month. The condition factor, gonadosomatic, hepatosomatic and stomach fullness indexes were analyzed. None of the morphophysiological indexes showed any clear tendency. From 377 gonads, both male and female, five developmental stages were characterized for each sex. L. peru shows asynchronous gonad development and multiple spawning. Two spawning period were observed in 1993 (March, and August- September) and three in 1994 (April-May, July-August, and November), with a maximun in August of both years. Length at first maturity for the females of L. peru was estimated at 295 mm fork length
