Nutrient Requirement of African Sneakhead Fish ( Parachanna obscura , Gunther 1861): a Review

The domestication of new species in aquaculture, strongly contributed to the promotion of the aquaculture in the recent years. Fish need lipids, energy, protein vitamins and minerals in their feed for to insure growth, reproduction, and other physiological functions. Several studies have been made on P. obscura in sight of its domestication. Dietary protein requirement, dietary lipid requirement and dietary carbohydrate requirement of P. obscura were previously studied. The aim of this study is to make a bibliographical on the nutrient requirements of the African snakehead fish ( P. obscura ) in order to promote P. obscura rearing. Protein requirements of P. obscura larvae are between 45 and 55.5% whereas for fingerlings are 42.5 and 53.5% of the diet. The optimal carbohydrate requirement of P. obscura fingerlings is 12% of diet and maximum crude lipid is 7% of the diet.
