| Abstract/Description: | A 45-day feeding trial was conducted to evaluate the effect of dietary lipid/essential fatty acid (EFA) level on growth performance in Litopenaeus vannamei reared at 2, 25 and 50‰ salinity. Three iso-nitrogenous (374 g/kg) experimental diets were formulated to contain 30, 60 and 90 g/kg of lipid having 6, 12 and 24 g/kg of EFA (Diet-30/6, Diet-60/12 and Diet-90/24), respectively. A total of 540 healthy acclimatized shrimps (6.44±0.31 g) were transferred into 27 experimental tanks (500 L) in triplicate (20 shrimps/tank). Results of 2X2 factorial design (salinity and lipid/EFA level) showed a significantly (P<0.05) higher weight gain of 135.65% at 25‰. Diet-60/12 and Diet-90/24 exhibited significantly (P<0.05) higher growth compared to Diet-30/6. A high correlation was observed among the salinities (r=1.0000 and 0.9696). Survival was significantly high at 25‰ (84.44%) compared to 2‰ (46.66%) and 50‰ (40.55%). The hemolymph protein level enhanced significantly with increased dietary lipid/EFA level but not due to salinity. Triglycerides and cholesterol decreased significantly with increased salinity, whereas the reverse was true due to dietary change. Both salinity and lipid/EFA level had a significant (P<0.05) effect on body composition. Results revealed that increasing dietary lipid/EFA level enhances the tolerance of L. vannamei at both hypo (2‰) and hyper (50‰) saline conditions, but would not be beneficial while rearing at 25‰. |
