|
The present study was carried out to compare the differance of proximate composition and lipid peroxides in juvenile(80~120g) and adult(670~690g) rainbow trout(Oncorhynchus mykiss). There was a marked increase in lipid content with growth. The fatty acids of juvenile rainbow trout was composed of saturates, monoenes and polyenes of 30.18%, 37.81% and 25.09%, respectively. Adult rainbowtrout showed higher content in monoenes and lower content in polyenes. The composition of amino acid was similar. In both groups, glutamic acid, aspartic acid, histidine were abundant. The lipid peroxides, malondialdehydes and lipofuscin, were not increased significantly with growth.
