Abstract
This study investigated the nutritional composition of the polychaete including protein, lipid, fiber, moisture, fatty acids and amino acids. Polychaetes were collected from farmed and wild conditions. The results of this study showed that the contents of protein, lipid and moisture in polychaete P. nuntia var. brevicirris (wild), P. nuntia var. brevicirris (farmed), P. nuntia (wild) and M. mossambica (wild) were 12.57%; 13.19%; 8.47% and 11.81% as protein, 3.53%; 3.64%; 1.66% and 2.51% as lipid, and 76.40%; 77.48%; 86.23% and 79.13% as moisture, respectively. The results showed that there is a significant difference of fatty acid profile between polychaetes collected from farmed and wild condition (p<0.05). Most fatty acids (SFA) 1012.7; (MUFA) 716 and (PUFA) 114.7 (mg/g) of polychaete P. nuntia var. brevicirris (farmed). Amino acids were identified, including 10 essential and 7 nonessential of polychaete. The results suggest that P. nuntia var. brevicirris worms from the farmed aquaculture have high nutritional composition and unsaturated fatty acid content and can be used in marine shrimpbroodstock maturation.
