Abstract:
Lipid classes, fatty acids, free amino acids and
protein content in captive Atlantic halibut (Hippoglossus hippoglossus)
eggs were measured to investigate the changes in the biochemical composition
of eggs and larvae in both the embryonic and early larval stages. Total free
amino acids decreased continuously (p < 0.01) over the embryonic
and larval stages investigated. Triacylglycerol was significantly greater at
hatch than at all other stages (p < 0.05). When hatching
occurred, there was also a significant increase in all phospholipid classes.
It is suggested that free amino acids may be the source of carbon skeletons
for lipid synthesis at hatching.
