Annual reproductive cycle and fecundity of Scorpaena notata (Teleostei, Scorpaenidae)
Marta Muñoz, Maria Sàbat, Silvia Vila, Margarida Casadevall

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 changes in the gonads and of various indices related to reproduction. Sexual dimorphism does not occur in the population we studied, which is clearly dominated by males. Multiple spawning takes place between July and October, consisting of between 6,000 and 33,000 eggs per female, each of about 500 µm in diameter. The fecundity of the species is determined by the size and weight of the individuals.
