      Pacific bluefin is a highly valuable pelagic species that inhabits a broad range in the North Pacific Ocean. The reproductive biology, especially for the spawning aggregation in the south-western North Pacific Ocean, is not well understood. Thus, a total of paired ovary specimens were collected from the Taiwanese longline fleet during the fishing season (late April through June) to Cited by:   The reproductive biology of male skipjack tuna Katsuwonus pelamis was examined from May to December in the tropical western and central Pacific Ocean. Testis maturity was classified into five stages (i.e., immature, early maturation, mid maturation, late maturation, and regression) on the basis of morphological changes in the germinal by:

The reproductive biology of yellowfin tuna (Thunnus albacares) was examined in rela- tion to seasonality, their vulnerability to capture, and fisheries interaction in the central and western Pacific Ocean. The reproductive biology of female yellowfin tuna (Thunnus albacares; YFT) was studied through the estimation of some important traits: sex-ratio, size at maturity (L50), spawning seasonality.

Developmental stages of oocyte maturation and degenerative stages of postovulatory follicles in yellowfin tuna from the eastern Australian Fishing Zone of the Coral Sea are described.

The time of spawning of yellowfin appeared to be during the late evening and early morning. Final oocyte maturation occurred in less than 24 h; postovulatory follicles could not be identified in ovaries after 24 Cited by: Aspects of the Reproductive Biology of Yellowfin Tuna, Thunnus albacares, in the Northern Gulf of Mexico Aspectos de la Biología Reproductiva del Aatún Aleta Amarilla, Thunnus albacares, en el.
