The objective of this study was to evaluate the influence of different dietary lipid and fatty acids on the nutritional value of bioflocs used as a feed,as well as shrimp performance and health. A total of 1800 Litopenaeus vannamei juveniles (2.87 0.01 g) were cultured in biofloc technology, with a density of 200 shrimp m2 , and fed with three isoproteic experimental diets at different lipid levels (85 g kg1 , 95 g kg1 and 105 g kg1 ); each treatment was performed in triplicate. After 61 days, no significant difference was observed (P > 0.05) among the water qualityparameters. For the shrimp performance, significant difference was observed (P = 0.011) among the values of survival, where treatments with lower lipid levels had higher survival (92.5 3.5% and 91.0 2.5%). Although there are significant differences in survival, no significant differences in the total haemocytes count (THC) were observed. For other growth performance, no differences were observed (P > 0.05). A positive correlation (r = 0.75) has been observed between the dietary oleic acid and bioflocs. The bioflocs howed ?long-chain? polyunsaturated fat acids (lcPUFA), especially arachidonic acid. The shrimp showed similar growth and stayed healthy at the end of the experimental period. |
