Reproductive aspects (spawning season, size and weight at maturity, and fecundity) of Octopus hubbsorum are reported for Espíritu Santo Island, southern Gulf of California (Mexico). A total of 230 octopuses were captured (46% females and 54% males) between June 2006 and June 2007. The sex ratio was...

| description | Reproductive aspects (spawning season, size and weight at maturity, and fecundity) of Octopus hubbsorum are reported for Espíritu Santo Island, southern Gulf of California (Mexico). A total of 230 octopuses were captured (46% females and 54% males) between June 2006 and June 2007. The sex ratio was not significantly different from 1:1 (P > than 0.05) except in November, when more males were captured than females. Four sexual maturity stages were established for both sexes: immature, maturing, mature, and prespawning (for females) or spawning (for males). The principal spawning season of O. hubbsorum occurred in autumn, when sea surface temperature ranged from 24 to 29 ºC. The size and weight at maturity were 390 mm and 445 g, respectively, for males and 490 mm and 680 g, respectively, for females.

Se reportan los aspectos reproductivos (temporada de desove, la talla y el peso de madurez, y la fecundidad) de Octopus hubbsorum para la Isla Espíritu Santo, sur del Golfo de California (México). Se capturó un total de 230 pulpos (46% hembras y 54% machos) entre junio de 2006 y junio de 2007. La proporción sexual no fue significativamente diferente a 1:1 (P > a 0.05) a excepción de noviembre, cuando se capturaron más machos que hembras. Se establecieron cuatro fases de madurez gonádica para ambos sexos: inmaduro, desarrollo, maduro y predesove (para hembras) o desove (para machos). La principal temporada de desove de O. hubbsorum se presentó en otoño, cuando se registró una temperatura superficial del mar entre 24 y 29 ºC. La talla y el peso de madurez fue de 390 mm y 445 g, respectivamente, para los machos y de 490 mm y 680 g, respectivamente, para las hembras. La fecundidad potencial promedio fue de 205,144 ovocitos por hembra y la fecundidad relativa promedio fue de 309 ovocitos por gramo de peso corporal de la hembra. Aparentemente las hembras en desarrollo utilizan sustancias provenientes de la glándula digestiva. |
