Abstract

CACERES-MARTINEZ, Jorge; VASQUEZ-YEOMANS, Rebeca  and  GUERRERO-RENTERIA, Yanet. Early Gametogenesis of Kumamoto oyster (Crassostrea sikamea). Hidrobiológica [online]. 2012, vol.22, n.2, pp.181-184. ISSN 0188-8897.

The Kumamoto oyster, Crassostrea sikamea, starts gametogenesis as young as 71 days old from spawning (35 days from post-settlement) with a mean shell height of 3.0 mm. This information constitutes a new record in age-size for gametogenesis in oysters for commercial importance and adds another biological difference comparing this species with the Pacific oyster Crassostrea gigas.

Keywords : Crassostrea sikamea; gametogenesis; gonadal development; Kumamoto oyster; sexual differentiation.
