Abstract:
The study was conducted to assess the effect of fucoidan (bioactive compound) incorporated diet on growth rate of Macrobrachium rosenbergii. The polysaccharide fucoidan from brown seaweed Padina tetrastromatica was extracted and it was incorporated with pellet diets at three concentrations (1%, 2% and 3%). The fucoidan incorporated diets were fed to prawn M. rosenbergii for 3 months and the growth performance was assessed. The growth parameters of prawn like weight gain, Specific Growth Rate (SGR) and Feed Conversion Ratio (FCR) in different experimental treatments were recorded every fortnight. Highest average weight gain was recorded in treatment with 3% fucoidan. Similarly, fucoidan fed prawn group displayed higher SGR and better FCR when compared to the control diet fed prawn group. Form the present work it could be established that the  ncorporation of fucoidan in the diet is effective in increasing the growth of Macrobrachium rosenbergii.
