Influence of Different Non-Conventional Feeds on Fatty Acid Profile of Mozambique Tilapia (Oreochromis mossambicus)

The present study was performed to investigate the influence of different non-conventional feeds on the Fatty Acid (FA) composition of Mozambique tilapia Oreochromis mossambicus. Three isonitrogenous and isoenergetic diets were used viz., Earthworm Meal (ETM), Poultry Offal Meal (POM) and Market Available Feed (MAF). Each diet was fed to triplicate groups of 20 fish. The feeds influenced (p<0.05) fatty acid profile of fish flesh. Fillet FA profile of fish fed MAF diets had significantly higher (p<0.05) concentrations of SFA and MUFA but lower PUFA compared to fish fed ETM and POM diets. Fillet of fish fed the ETM diet had higher (p<0.05) concentrations of PUFA as well as EPA and DHA compared with fish fed the other diets. The results of this study shows that feed formulated with non-conventional sources as key ingredient have better impact on FA profile of fish fillet than the feed available in market.
