Abstract
In order to estimate the influence to maturation of kuruma prawn Marsupenaeus japonicus by the chemical components in wild prey, we analyzed an effect of organic compounds in the prey worm, such as a polychaeta Perinereis nuntia. The tissue lipids in Perinereis nuntia might have an activity for maturation of kuruma prawn. The lipid and fatty acid compositions of the crude lipid in Perinereis nuntia were determined, and it had very low levels of DHA compared with other marine animal lipids. The maturation of kuruma prawn might not be influenced by these n-3 polyunsaturated fatty acids(PUFA)containing DHA, because the low levels of n-3 PUFA in Perinereis nuntia were also observed.
