军曹鱼营养需求与饲料研究进展

目前, 养殖鱼类已成为满足人类对水产品需求的主要来源。军曹鱼(Rachycentron canadum)具有生长速度快、肉质细嫩鲜美、营养价值高等特点, 已成为我国南方重要的海水网箱养殖鱼类。然而, 目前饲养军曹鱼仍主要依靠冰鲜杂鱼, 特别是大规格鱼的养殖, 这严重制约其养殖业的健康发展, 研发适合不同生长阶段需要的配合饲料非常必要。文章重点总结了军曹鱼对蛋白质、脂肪、氨基酸、脂肪酸、微量营养素等的需求, 饲料中鱼粉和鱼油替代研究, 饲料添加剂应用及其饲料产业发展现状, 以期为军曹鱼营养需求和配合饲料开发的深入研究提供参考。

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.
