| Abstract |
Innovative techniques opened new perspectives in the larviculture or the Asian seabass in the 1980s. Induced spawning maximized egg production while sperm preservation reduced the problem of male brood-stock supply. Studies of biometric characteristics of the fish larvae resulted in improved feeding strategies with live food. This in turn permitted a more rational use of expensive Artemia nauplii. Nutritional enhancement of the highly unsaturated fatty acid (HUFA) composition of the life food resulted in significant improvement of survival and physiological condition of the larvae of the metamorphosis. A salinity stress test enabled the evaluation of the larvae's physiological status and estimation of their HUFA-requirements during the hatchery and pre-nursery phase. |
