Abstract：
Aquaculture contributes to the sustainable development of food security, marine resource conservation, and economy. Shifting aquaculture feed from fish meal and oil to terrestrial plant derivatives may result in cost savings. However, many carnivorous fish cannot be sustained on plant-derived materials, necessitating the need for the identification of important factors for farmed fish growth and the identification of whether components derived from terrestrial plants can be used in feed. Herein, we focused on the carnivorous fish leopard coral grouper (P. leopardus) to identify the essential growth factors and clarify their intake timing from feeds. Furthermore, we evaluated the functionality of starch, which are easily produced by terrestrial plants. Results reveal that carbohydrates, which are not considered essential for carnivorous fish, can be introduced as a major part of an artificial diet. The development of artificial feed using starch offers the possibility of increasing the growth of carnivorous fish in aquaculture.
摘要：
水产养殖有助于粮食安全的可持续发展,海洋资源保护,和经济。将水产养殖饲料从鱼粉和油转移到陆生植物衍生物可能会节省成本。然而,许多食肉鱼类不能在植物来源的材料上维持，需要鉴定养殖鱼类生长的重要因素，并鉴定来自陆地植物的成分是否可以用于饲料。在这里，我们重点研究了食肉鱼豹珊瑚石斑鱼(P.leopardus）以确定必需的生长因子并阐明其从饲料中的摄入时间。此外，我们评估了淀粉的功能性，很容易由陆生植物生产。结果显示，碳水化合物，这对食肉鱼类来说并不重要，可以作为人工饮食的主要部分引入。使用淀粉的人工饲料的开发为增加水产养殖中食肉鱼类的生长提供了可能性。
