title: Effects of dietary Dunaliella salina extract and highly unsaturated fatty acids on the fecundity and lipid content of pond-reared Penaeus japonicus brood-stock.
abstract: Five basic diets containing fresh squid meat and trash fish were supplemented with different amount of Dunaleilla salina extract (DSE) and highly unsaturated fatty acids (HUFA). Supplemented diets were fed to pond-reared Penaeus japonicus broodstock. Diet A was solely squid and trash fish. Diets B 1 and B2 were supplemented with 400 and 600mg DSE.kg-1 diet, respectively. Diets C1 and C2 were supplemented with HUFA 5 and 10g.kg-1 and 400mg.kg-1DSE, respectively. The results showed that the group fed diet C2 had the best reproductive performance in all experimental groups. It had the highest proportion of spawns (73.5%) and egg production per female (589.0) than all the other experimental groups. The fatty acid composition strongly affected fecundity and stress tolerance of broodstock. The results showed that both HUFA and beta-carotene DSE may play role in stress tolerance and reproductive performance
