Abstract
Although zebrafish is used as a major model species for understanding a number of biological functions and mechanisms involved, there is practically no information on the nutritional requirements of this cyprinid. The rearing practices, especially with regard to feeds and feeding, also vary considerably. To obtain base line information on the nutrient requirements and to develop a standard diet, we initiated the present work of feeding zebrafish larvae with a formulated feed right from first feeding onward. Growth of zebrafish fed the compound feed was very good, reaching a total length of 23 ± 4 mm in 9 weeks with a survival rate of 89% ± 4%. We present the first ever published data on whole-body composition in terms of essential amino acids (ideal protein profile), total, neutral and polar fatty acid profiles, minerals, and trace elements. Results obtained here show clearly that zebrafish can be reared with formulated feed right from mouth opening without resorting to any live prey.
