摘要

摘要本试验旨在研究在饲料中添加海葡萄(Caulerpa lentillifera)对遮目鱼(Chanos Chanos)生长性能和存活率的影响(forssk, 1775)。体重在0.20-0.25 g/ind之间的200条鱼被随机分配到25 L鱼缸中的20个。在4种配方饲料中分别添加0(对照)、10、20、30和40 g/kg的扁豆菜粉,饲喂49 d。结果表明,饲粮中添加扁豆粉对肉鸡的绝对增重、绝对增长、特定生长率和饲料效率均有显著影响(p < 0.05)。处理C (20 g/kg饲粮)的特定生长率、绝对体重、绝对长度和饲料效率最高,分别为1.597±0.137 %/d、4.47±0.08 g、2.98±0.77 cm和69.86±2.72%。由此可见,推荐在20 g/kg的饲料中添加海葡萄(Caulerpa lentillifera)以获得遮目鱼(Chanos Chanos)的最佳生长。摘要:Penelitian ini bertujuan untuk mengetahui pengaruh suplementasi pakan anggur laut Caulerpa lentillifera terhadap pertumbuhan dan kelangsungan hidup ikan bandeng, Chanos Chanos (forsk, 1775)。Dua ratus ikan样品berbobot berkisar 0.20-0.25 g/ d,分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布、分布Hasil penelitian menunjukkan bahwa penberian tepung C. lentillifera dalam ransum memberikan pengaruh nyata terhadap laju pertumbuhan种,bobot mutlak, panjang mutlak和efisiensis pakan (P0.05)。拉州巴图布罕、bobot木特拉克、panjang木特拉克、巴坎阳最适配巴图拉克C(日粮20 g/kg),登干尼莱1.597±0.137 %/hari, 4.47±0.08 g, 2.98±0.77 cm丹69.86±2.72%。伯尔坦登加哈西尔,丹参加巴尼哈加20 g/kg巴尼哈加,巴尼哈加20 g/kg巴尼哈加,巴尼哈加最适巴尼哈加。

Effects of Dietary Caulerpa lentillifera Supplementation On Growth Performance and Survival Rate of Milk Fish, Chanos chanos (Forsskål, 1775)
Abstract: The study aimed to investigate the dietary supplementation effect of sea grape, Caulerpa lentillifera, on the growth performance and survival rate of milkfish, Chanos chanos (Forsskål, 1775). Two hundred fish weighing in the range of 0.20-0.25 g/ind were randomly distributed into 20 of 25 L tanks. The 0 (control), 10, 20, 30, and 40 g/kg of Caulerpa lentillifera powder was supplemented into four formulated feeds and then fed for 49 days. The result exposed that the administration of Caulerpa lentillifera powder in the diet provided a significant effect on the absolute weight gain, absolute length gain, specific growth rate, and feed efficiency (P<0,05), but there was no significant effect on survival rate (P>0,05). The optimum specific growth rate, absolute weight, absolute length and feed efficiency were found at treatment C (20 g/kg diet) with the values of 1.597±0.137 %/days, 4.47±0.08 g, 2.98±0.77 cm and 69.86±2.72 %, respectively. Regarding this result, the supplementation of sea grape (Caulerpa lentillifera) at a 20 g/kg diet is recommended to obtain the optimum growth of milkfish (Chanos chanos).Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh suplementasi pakan anggur laut Caulerpa lentillifera terhadap performa pertumbuhan dan kelangsungan hidup ikan bandeng, Chanos chanos (Forsskål, 1775).
