Annual reproductive cycle and fecundity of Scorpaena notata (Teleostei, Scorpaenidae)
Scorpaena notata (Teleostei: Scorpaenidae) is an oviparous species with external fertilisation that shows some unusual features in its gonadal morphology and gametogenesis. In this work we analyse the annual reproductive cycle and the fecundity of this species by studying the monthly histological ch...
