Abstract
Effects of dietary incorporation of astaxanthin on growth and selected immune parameters of freshwater prawn Macrobrachium rosenbergii were examined. Sub-adult M. rosenbergii were fed diets fortified with astaxanthin at 0 (control) 25 50 100 and 200 mg kg- for a period of 28 days. Results revealed a significant increase (P0.05) in specific growth rate of prawns fed 50 100 and 200 mg kg- astaxanthin enriched diet compared to the control diet. Among the immune parameters evaluated phenoloxidase activity and total protein showed a significant increase (P0.05) in prawns fed diets enriched with 50 100 and 200 mg kg- astaxanthin. The total haemocyte count was also significantly higher in prawns fed diets enriched with 50 and 100 and 200 mg kg- astaxanthin. Total carotenoid content in muscle exoskeleton and hepatopancreatic tissues showed a dose dependent increase. The present results showed that dietary incorporation of astaxanthin at 50 100 and 200 mg kg- level had significant positive effects on growth and immune response of M. rosenbergii.
