Halibut larvae at an age of 267 day degrees post hatching, were reared through first
feeding, outdoors in 100 l plastic bags. There were three feeding regimes: wild
zooplankton, Artemia enriched on the algae Isochrysis galbana and Artemia enriched
with "Super Selco". The larval growth was very low the first three weeks probably due
to low temperature and high larval age at onset of exogenous feeding. At Day 16 the
mean myotome height and dry weight were significantly higher for the group fed wild
zooplankton, than for the Artemia groups, and the larvae fed Super Selco enriched
Artemia had a significant higher myotome height and dry weight than the larvae fed
Isochrysis enriched Artemia. There were no significant differences in larval size at Day
23. The low survivals of the two groups fed Artemia, could have been caused by the
incomplete digestion of Artemia.
