Effect of dietary phospholipids and n-3 highly unsaturated fatty acids on ovarian development of kuruma prawn [Penaeus japonicus]

Effect of dietary phospholipids and n-3 highly unsaturated fatty acids on ovarian development of kuruma prawn [Penaeus japonicus]

The influence of diets complete in or free from either phospholipid (soybean lecithin) or n-3 highly unsaturated fatty acids (n-3 HUFA, squid liver oil) on the gonadosomatic index (GSI) and tissue lipid composition of ablated female Penaeus japonicus (mean weight=20.2±0.9g) were determined. Bilatera...

Zusammenfassung:The influence of diets complete in or free from either phospholipid (soybean lecithin) or n-3 highly unsaturated fatty acids (n-3 HUFA, squid liver oil) on the gonadosomatic index (GSI) and tissue lipid composition of ablated female Penaeus japonicus (mean weight=20.2±0.9g) were determined. Bilateral eyestalk ablation was performed 31-37 days after feeding on experimental diets and GSI was examined after 20 days of each prawn's ablation. Supplementation of both phospholipid and n-3 HUFA resulted in the highest GSI (3.0±0.8, P
