Ảnh hưởng thức ăn, khẩu phần ăn của cá chuối hoa (<i>Channa maculate</i> Lacepède, 1801) bố mẹ lên khả năng sinh sản, chất lượng trứng và cá bột

Abstract

    This study aims to develop the seed production technology of Blotched snakehead (Channa maculate Lacepède, 1801) under artificial condition. Two experiments were conducted. Experiment 1: selected food to feed broodstocks with 3 experiments: fed with 100% of trash fish (NT1); fed with 50% of trash fish and 50% industrial feed (NT2); and 100% industrial feed (NT3). Experiment 2: determined food ration for broodstocks to fertility with ration from 5% to 11% body weight. The results showed that feeding with 50% of trash fish and 50% industrial food, diet feed of broodstocks as 9% body weight is most appropriate to improve fertility, quality of eggs and larvae of blotched snakehead.
