Abstract: The aim of the present study is to compare the efficiency of algal, synthetic and other natural astaxanthin on growth and survival of Penaeus monodon larvae. Four diets: algal astaxanthin-added diet (AAD, astaxanthin was collected from Haematococcus pluvialis NIES144), synthetic astaxanthin-added diet (SAD), non-astaxanthin supplemented diet (CD) and natural food (NF) were fed to shrimp larvae of different stages. The larvae fed with AAD showed the highest survival rate and had the same growth rate as the group fed NF. Both larvae fed with AAD and NF showed significant higher growth rate than the groups fed SAD and CD (P<0.05).

Abstract: The aim of the present study is to compare the efficiency of algal, synthetic and other natural astaxanthin on stress resistance of Penaeus monodon larvae. Four diets: algal astaxanthin-added diet (AAD, astaxanthin was collected from Haematococcus pluvialis NIES144), synthetic astaxanthin-added diet (SAD), non-astaxanthin supplemented diet (CD) and natural food (NF) were fed to shrimp larvae of different stages. The test of changing salinity was done when the larvae came to postlarvae 15. The group fed with AAD could tolerate in low salinity stress better than the group fed with SAD, NF and CD. Carotenoids contents in shrimp larvae fed with NF, AAD, SAD and CD were 179.54 plus or minus 0.65, 122.57 plus or minus 5.62, 109.67 plus or minus 0.47 and 97.33 plus or minus 3.42 ppm, respectively.
