Abstract

This paper describes the large-scale production of eggs and larvae of sea bass (Dicentrarchus labrax) and shows how spawning can be planned to produce viable eggs throughout the year by manipulation of photoperiod and temperature. The rearing temperature was 9.5-22 °C during spawning and 9-24 °C during the gametogenesis. The photoperiodic cycles tested were normal (i. e. the photoperiodic cycle observed at Palavas-les-Flots, mediterranean coast, France, 1984/1987) advanced by 3 to 5 months and delayed by 2 months.
