Effect of enriched natural diet on survival and growth of juvenile cuttlefish Sepia officinalis L.

Effect of enriched natural diet on survival and growth of juvenile cuttlefish Sepia officinalis L. Juvenile cuttlefish hatched in the laboratory were reared for 30 days with different enriched diets, in spring and in summer. The groups fed an enriched natural diet exhibited a high rate of survival even when seawater quality decreased during the summer. The natural diet enriched in polyunsaturated fatty acids (PUFA) induced faster growth in juvenile cuttlefish; the stimulating effect of PUFA on growth was evident during the very early juvenile stage, and the benefit resulted is conserved during further growth. The maximum daily ration was lower in groups fed with the enriched diet than in the control. These data indicate the importance of n −3 PUFA such as docosahexaenoic acid (DHA; 22:6 n −3) and eicosapentaenoic acid (EPA; 20:5 n −3) in cephalopod juvenile nutrition. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Aquaculture Elsevier

Abstract

Juvenile cuttlefish hatched in the laboratory were reared for 30 days with different enriched diets, in spring and in summer. The groups fed an enriched natural diet exhibited a high rate of survival even when seawater quality decreased during the summer. The natural diet enriched in polyunsaturated fatty acids (PUFA) induced faster growth in juvenile cuttlefish; the stimulating effect of PUFA on growth was evident during the very early juvenile stage, and the benefit resulted is conserved during further growth. The maximum daily ration was lower in groups fed with the enriched diet than in the control. These data indicate the importance of n −3 PUFA such as docosahexaenoic acid (DHA; 22:6 n −3) and eicosapentaenoic acid (EPA; 20:5 n −3) in cephalopod juvenile nutrition.
