摘要

Atlantic halibut, Hipyoglossus hippoglossus (L,), eggs originating from one female were evenly distributed between four silos (4.8 m(3)) shortly prior to hatching. At days 30, 35, 40 and 44 after hatching [i.e. 200, 230, 260 and 290 day-degrees (days degrees)], the larvae were successively collected and transferred to indoor start feeding tanks, and larvae were offered a diet of instar II Artemia nauplii which had been enriched short time (24 h). A significant correlation was found between the age of the larvae and onset of first feeding. The larvae transferred to start-feeding incubators at 290 days degrees were able to capture Artemia only a few hours after transfer, whereas it took 6 days for the larvae transferred at 200 days degrees to reach a corresponding ingestion level. Larval growth was also positively correlated to both larval age and prey consumption, However, there were no differences in survival between the larval groups.
