Influence of dietary microalgal concentrates on growth, survival and health status of Penaeus vannamei

The present study evaluated the nutritional value and antimicrobial activities of Thalassiosira weissflogii and Tetraselmis sp. concentrates. The study also ascertained the effect of microalgae supplemented diets on the growth and survival of Penaeus vannamei post larvae (PL 18, mean weight: 19.714 ...

Description
Summary:The present study evaluated the nutritional value and antimicrobial activities of Thalassiosira weissflogii and Tetraselmis sp. concentrates. The study also ascertained the effect of microalgae supplemented diets on the growth and survival of Penaeus vannamei post larvae (PL 18, mean weight: 19.714 ± 1.62 mg). Microalgae concentrates were prepared by flocculation, and the proximate composition showed no significant difference in the crude protein content between these species ( T. wesissflogii : 43.07 ± 1.78%; Tetraselmis sp. 42.11 ± 2.55%; p  > 0.05). However, the crude lipid content of T. weissflogii was significantly ( p
