En este trabajo se realizó el estudio sobre el desarrollo embrionario del pulpo común a 14ºC y a 18ºC y el efecto del cuidado materno. Los resultados muestran que la temperatura tiene un efecto marcado en el tiempo de desarrollo y que el cuidado mater no no afecta al desarrollo embrionario. A 18°C el tiempo de desarrollo fue de 40 días y a 14°C el tiempo de desarrollo fue de 64 dí as. A 18°C, se alcanzaron las estadios de Naef antes que a 14°C. Del mismo modo, el índice de desarrollo (DI) indica que caracterí sticas de diferenciación embrionaria fueron alcanzadas siempre antes a 18°C que a 14°C. Al final del desarrollo embrionario, no hubo diferencias en la longitud de l huevo, para los dos supuestos. Sin embargo, el aumento de longitud del huevo fue más evidente y visible cuando el embrión se comenzó a formar y con valores mayores a 14ºC que a 18ºC . L a longitud de embriones, la longitud del brazo, el diámetro del ojo, el peso del vitelo y el peso del huevo fue similar (p> 0,05) para ambas temperaturas, independientemente del cuidado materno, al final del período de desarrollo embrionario. Del mismo modo, no hubo diferencias en el peso ni en embriones ni en paralarvas reci én eclosionadas a las dos temperaturas ni con cuidado materno ni sin el
This work presents a study on the effects of two temperatures (14ºC and 18ºC) and incubation (artificial vs . female care) on the embryonic development of Octopus vulgaris . Results showed that type of incubation does not affect the embryonic development. For that reason data obtained from embryos incubated both artificial and by female were grouped. Temperature had a marked eff ect on embryonic development time of O. vulgari s . At 18ºC, embryonic development was of 40 days, while at 14ºC it was of 64 days. Temperature of 14 and 18°C were in the tolerance range of the species without affecting the morphological characteristics of hatchlings. Results showed that temperature modu lated in a different form the embryonic development, at least until stage XV where embryos maintained at 18°C showed values of eggs and embryo length lower than observed in embryos maintained at 14°C. t he fact that there were no differences between hatchli ngs maintained at both experimental temperatures demonstrates that O. vulgaris embryos can be favored if spawn occurs at relatively low but increasing temperatures, which contributes to a shorter planktonic life that will impact into the settle.
