Observations on yellowtail snapper maturation indicated a long spawning season (March to October), including two periods of high sexual activity (March and July). Twenty-one batches of good quality eggs (mean viability rate 85%) were recorded without hormonal treatment. Spawning was also induced by...

Zusammenfassung:	Observations on yellowtail snapper maturation indicated a long spawning season (March to October), including two periods of high sexual activity (March and July). Twenty-one batches of good quality eggs (mean viability rate 85%) were recorded without hormonal treatment. Spawning was also induced by HCG injection. Fecundity was high (172 000 eggs/kg), but the viability rate remained low (31%).
