Abstract：
:Variations in some enzyme activities during larval development of sea bass fed live prey were investigated from hatching to day 40. Fluctuations in the enzyme specific activities (except for trypsin) occurred in three phases: initially a sharp increase until day 12, followed by a plateau and subsequently a decrease around day 23. Then activities remained constant until day 40. Trypsin activity kept rising until day 23, then fell. Enzymatic adaptation to a change in diet was studied by feeding larvae with microparticulate diet from day 25. Adaptation to dietary change was observed for amylase, alkaline phosphatase and leucine aminopeptidase, assayed in whole larvae. In larvae fed microparticulate dry diet, the activities of these three enzymes tended to be higher than in those fed natural prey. Although poor growth was observed in larvae fed microparticles, the brush border enzyme activities purified from whole body homogenate, were not impaired.
