Effects of <i>Haematococcus pluvialis</i> on growth performance, hepatopancreatic transcriptome and resistance to ammonia-nitrogen stress of pacific white shrimp (<i>Litopenaeus vannamei</i>).

ABSTRACT: Astaxanthin is widely used in aquatic animal feed and has beneficial effects on aquatic animals. Haematococcus pluvialis is one of the most important sources of natural astaxanthin. In this 8-week feeding experiment, the impacts of gradient additions of H. pluvialis on the growth and physiological performance of Litopenaeus vannamei before and after acute ammonia nitrogen stress were investigated. The experimental diets were formulated by incorporating gradient levels (0%, 0.02%, 0.04%, 0.08%, 0.16% and 0.32%) of H. pluvialis into the feed, namely D0, D0.02, D0.04, D0.08, D0.16 and D0.32, respectively. Each tank housed 30 shrimp, with 4 replicates per group. Significant improvements were observed in weight gain and specific growth rate (P < 0.05) in D0.02
