碩士 / 國立高雄海洋科技大學 / 水產養殖研究所 / 101 / The study was aimed to find out analysis the Lates calcarifer growth rate applied replacement of fish meal by various fermented soybean meal. We are going to divide into two stages of experiments and use the fermentation feed which are fermented soybean meal 1, fermented soybean meal 2 and fermented soybean meal 3 to replacement of fish meal. The first phase were divided into A, B and control groups, a total of three groups, four repeat, control group feed commercial formula, and A, B group fermented soybean meal 1 and fermented soybean meal 2 replace 20% fishmeal in commercial formulations. The second phase were divided into groups A, B, C and control group, a total of four groups, three repeated,where A, B and control group renewal of the first stage of the experiment, C group fish out by the control component and replaced 20% fermented soybean meal 3 of the commercial formulations fishmeal feeding trials. Feeding time at every stage of each six weeks, and random sampling once every two weeks, weighed weight, feed for six weeks, the experimental data, we also use the SPSS software to be the experimental data. According to the statistical, the result display the A, B group compare with control group, gain weight, feed intake and feed conversion rate haven’t significantly different(p>0.05). However, compare with A and control group, the specific growth rate are significantly different (p<0.05), C group haven’t significantly different too. The second stage, the result display the A, B, C group compare with control group, gain weight and feed conversion rate haven’t significantly different(p>0.05). But A, B and C group compare with control group, those specific growth rate and feed intake are significantly different(p<0.05). After testing, in measuring Viscerosomatic index and the length of the intestinal microvillus. Viscerosomatic index A, B, Cgroup compare with control group have significantly different (p<0.05), and A, B, C group between have significantly different, index B group> C group> A group> control group; the length of the intestinal microvillus especially the preceding part of m icrovillus bigger than posterior segment microvillus, preceding part of microvillus A, B, C group compare with control group have significantly different (p<0.05), and A, B, C group between have significantly different, length of B group> A group> C group> control group, posterior segment microvillus A, B, C group compare with control group haven’t significantly different(p>0.05). Spine bone analysis, zinc and phosphorus content is normal in the Lates calcarifer . The above results feed fermented soybean meal to replace 20% fishmeal is no effect on the growth of Lates calcarifer.
