Studies on the Relation between Constitution and Disease in Cultured-fishes.

1.本研究从A到E分为5个部分，如表35所示。采用肉眼观察、组织病理学和生化方法，比较了不同培养条件下的尾鳍形态和t值的差异。从饲料中添加维生素、维生素B_1、维生素B_2、维生素B_1、维生素B_2、维生素B_2、维生素B_1、维生素B_1、维生素B_2、维生素B_2、维生素B_1、维生素B_2、维生素B_对黄尾鱼种的假结核进行了研究，探讨了维生素E的预防效果和实验注射病原菌的鱼病变的初步组织病理学变化。采用理化、生化等方法，对建立健康体检体系进行了研究。该署报告了在养殖鱼类包括黄尾鱼、虎斑鱼和红鱼身上发现这种病毒的新发现。表35总结了助学金合作研究的结果，表明研究人员之间的相互关系是成功的。本报告中提到的一些问题的研究应该在今后继续进行。

1. This study is divided into 5 parts from A to E as shown in Table 35. The A was compared a different kind of culture condition with the difference in the morphology of caudal fin and t-value by the method using with the naked eye, histopathological and biochemical technique. The B was discussed about the problem of food on cultured yellowtails including the additive effect of vitamin <B_1> and <B_2> into feed, poisoning due to degenerative fatty acid and the treatment by the ways using the histopathological and biochemical technique. The C was studied on pseudotuberculosis in yellowtail fingerlings in connection with the preventive effect of vitamin E and the initial histopathological changes in the lesion of the fish experimentally injected with the pathgenic bacterium. The D was studied on the establishment of physical examination by the ways using the physiochemical and biochemical technique. The E was reported on the new findings of the infection in cultured fish including yellowtail, tiger puffer and red sea bream.2. The results obtained by Grant-in Aid for Co-operative Research were summarized in Table 35 and showed the mutual relation among the researchers was successful.3. The studies on some problems as mentioned in this report should be continued in the future.
