Lipids, egg and larval quality in cod

Summary

The project consisted of two studies on lipid quality and performance of cod broodstock (wild and farmed), eggs and larvae. Data suggested that arachadonic acid and carotenoid pigment concentrations in eggs from farmed fish may be sub-optimal. In trials where larvae were fed on enriched rotifers, the lipid profile of larvae reflected that of the live feed. Results of this and other studies indicate that relatively high DHA concentrations and DHA/EPA ratios, low EPA concentrations and EPA/ARA ratios and high ARA concentrations are advantageous.
