The leopard grouper Mycteroperca rosacea is an endemic species from the northwestern coast of Mexico and, like other serranid fishes, it has a high commercial value; hence, it is a good candidate for cultivation. This study aimed to describe the reproductive cycle of the leopard grouper in the wild...

This study aimed to describe the reproductive cycle of the leopard grouper in the wild as a step toward evaluating its aquaculture and restocking potential. From March 2008 to February 2009, 197 specimens were collected in the Gulf of California, Mexico. Overall sex ratio was 3.6 females to 1.0 male. Significant differences (P < 0.05) in total length and body weight were found between sexes. Group-synchronous ovarian development was observed with one yearly spawning period from May to June. Males matured two months earlier than females. The reproductive cycle was divided into four periods, (1) maturation, (2) spawning, (3) post-spawning, and (4) resting. Significant variations in the gonadosomatic index, hepatosomatic index, visceral fat index, and condition factor were observed throughout the study period. In addition, nine individuals were classified as immature bisexuals and one grouper presented evidence of sex change. 2011 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48020747005 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.4A Vol.37 |

La cabrilla sardinera Mycteroperca rosacea es una especie endémica de la costa del noroeste de México y, al igual que otras especies de serránidos, tiene un alto valor comercial; por lo tanto, es una buena candidata para cultivo. El objetivo de este estudio fue describir el ciclo reproductivo de la cabrilla sardinera en el medio natural como un paso hacia la evaluación de su potencial acuícola y repoblamiento. De marzo de 2008 a febrero de 2009, 197 especímenes fueron recolectados en el golfo de California, México. La proporción de sexos total fue de 3.6 hembras a 1.0 macho. Se encontraron diferencias significativas (P < 0.05) en la longitud total y el peso corporal entre los sexos. Se observó un desarrollo ovárico del tipo sincrónico por grupo con un periodo de puesta anual de mayo a junio. Los machos maduraron dos meses antes que las hembras. Se describieron cuatro periodos dentro del ciclo reproductivo: (1) maduración, (2) desove, (3) posdesove y (4) reposo. Se observaron diferencias significativas en el índice gonadosomático, el índice hepatosomático, el índice de grasa visceral y el factor de condición durante todo el periodo de estudio. Además, se clasificaron a nueve individuos como bisexuales inmaduros y se encontró una cabrilla con evidencia de cambio de sexo. |
