Abstract

This study was carried out to determine the influence of highly unsaturated fatty acid (EPA, DHA) enriched Artemianauplii on growth and survival of postlarvae of Litopeneausvannamei(PL-1 to PL-15) in Persian Gulf and Oman sea ecology research center of Bandar Abbas. A complete randomized design with 5 treatments and 3 replicates using15 tanks containing 20 liters water each was chosen. The Artemianaupliiwere enriched with (0 to 4%) cod liver oil (treatments A to E) and the larvae were fed 6 times per day at 4 hours intervals. The postlarvae of treatment D which fed with Artemianauplii, 3% of enrichment significantly increased compared to other treatments (p<0.05).The highest survival rate regarding treatment E postlarvae which fed with Artemianauplii, 4% enrichment However with treatment D (3%) and C (2%) no significant difference (p>0.05) was found. The postlarvae of treatment control (A) which was fed with Artemianauplii that it was not enriched, had the lowest growth and survival rate.The present study demonstrated that the highly unsaturated fatty acid enriched Artemianaupliihas positive effect on enhancement of growth performance and survival rate of white leg shrimp postlarvae.
