Relationship of biochemical composition and fillet yield with size of Caspian Sea carp (Cyprinus carpio)

The present study was done to investigate the relationship of biochemical composition and fillet yield with size of Caspian sea carp (Cyprinus carpio). Obtained results showed that there was inverse regression relationship between moisture content with fish size, but there was a positive regression relationship between fish size with fillet lipid and energy content and fillet yield in wet weight. There was not any relationship between fish size with fillet protein and ash content. Fillet moisture content had an inverse regression relationship with lipid, protein and energy content. The results showed that fish size had a positive regression relationship with lipid content and fillet yield in dry weight. Fillet parameters which had relationship with fish size and moisture content will been measured rapidly for requested purpose without much cost. ^Corresponding author: Keywords: biochemical composition, fish size, Caspian sea carp (Cyprinus carpio), fillet yield
