PROGRESS IN NUTRITIONAL REQUIREMENTS AND FEED RESEARCH OF COBIA RACHYCENTRON CANADUM

Farmed fish has become the main source to meet the demand of human for aquatic products. Cobia Rachycentron canadum is one of the main farmed marine fish in southern China, which were cultured in sea net due to its fast growth, tender meat and high nutritional value. However, the cobia cultivation mainly depends on iced fresh fish, especially for the culture of large-size fish, which seriously restricts the development of farming industry. It is urgent to develop the corresponding formula for fish growth at different stages. This article summarized the research progress of cobia on nutrients requirements such as protein, fat, amino acids, fatty acids and micronutrients, the alternative of fish meal and fish oil in feed, the application of feed additives, as well as the developmental status of feed industry to provide reference for studies on nutritional requirements and the development of compound feeds of cobia.
