Abstract

The nutritional contribution of mideodeok extracts (ME) on rockfish (Sebastes schlegelii) feed and fish muscle was investigated. Different concentrations of the ME mixed with commercial diet were fed to mature rockfish for 8 weeks. The lipid and ash contents of the formulated diets were relatively similar to the control diet, while increasing the extract concentration increased the moisture content and decreased the protein contents. Major fatty acid components (C18:1n-9, 16:0, C20:5n-3, C22:6n-3) were of comparable quantity. High presence of C18:2n-6 was attributed to soybean oil incorporated in the diets, while the essential fatty acids were within limits (0.9-1.0%). The diet fortified with 6% ME produced the highest feed efficiency, with increased protein content in the muscle as well as lipid content for both muscle and liver. Hepato- and visceral-somatic index values were elevated with increasing ME concentration Muscle fatty acid contents were mostly C18:1n-9 and C16:0, with low absorption of C18:2n-6 in both the muscle and liver. Total highly unsaturated fatty acid content was significantly reduced in the fish muscle, but the values were higher for fish fed with a ME-fortified diet. An increasing trend for eicosapentaenoic acid and docosahexaenoic acid was also observed with increased ME fortification, with liver levels of these compounds remaining within range throughout the duration of the experiment.
