1. Rainbow trout were successfully reared under simulated seasonal changes. Behavioral and social characteristics of dominant fish were studied in grouped fish. (M. Tabata)2. Red sea bream larvae were successfully reared by self-feeder with newly devised optical fiber sensor. Seasonal diurnal feeding pattern except only for the summer was observed in grouped red sea bream. Water temperature had significant effect on main feeding peak. (K. Aida ＆ K. Furukawa)3. Yellowtails in floating net-pens displayed annual crepuscular plus nocturnal self-feeding pattern. They synchronized well with simulated annual photoperiod. Light was a primary self-feeding pattern of yellowtails. (J. Kohbara)4. Self-feeding network system was developed by operating remote control through internet. The system had several functions ; 1) monitor for self-feeding, 2) display and data saving, and 3) feed control. (M. Ichikawa ＆ K. Yamashita)5. Plasma glucose level of self-fed rainbow trout peaked at approximately the … More time of lights-off. Immunoreactivity to neuropeptide Y (NPY) in the ventral telencephalon was studied in self-feeding and fasted group. (T. Oishi)6. We demonstrated the effects of temperature and photoperiod on plasma and ocular melatonin rhythms in the self-fed trout. We also characterized melatonin receptors in the brain of European sea bass and demonstrated its daily variation. (M. Iigo)7. The single ayu showed diurnal feeding pattern when reared by self-feeding. Both tactile and optical fiber sensor was assessed in respect to availability for this species. (K. Yamamori)8. Self-feeding Nile tilapia had lower cortisol level. The self-feeding fish significantly exceeded the scheduled feeding fish in the phagocytic activity of macrophages, antibody production, and number of blood circulating lymphocytes. (M. Endo)9. Rainbow trout preferred a balanced amino acid diet over an unbalanced diet or a protein-free diet. Initially fatty trout reduced their energy intake compared to initially lean trout. (T. Yamamoto) Less

1.在模拟季节变化的条件下成功地饲养了虹鳟鱼。在群体中研究了优势鱼的行为和社会性特征。（M. Tabata）2.利用自行研制的光纤传感器成功地进行了真鲷幼鱼的自投喂。除夏季外，在分组的红鲷中观察到季节性的昼夜摄食模式。水温对主摄食高峰有显著影响。（K. Aida & K. Furukawa）3.浮游网笼中的黄尾鱼表现为周年性的黄昏+夜间的自食模式。它们与模拟的年光周期同步得很好。光照是黄尾鱼主要的自我进食模式。(J. Kohbara）4.通过互联网远程控制，开发了自动送料网络系统。该系统具有自动投料监控、显示和数据保存、投料控制等功能。（M. Ichikawa & K. Yamashita）5.自喂虹鳟鱼的血糖水平在大约200 ℃时达到峰值。 ...更多信息 熄灯时间观察自食组和禁食组大鼠端脑腹侧区神经肽Y（NPY）的免疫反应性。（T. Oishi）6.我们证明了温度和光周期对血浆和眼褪黑激素的节奏在自喂鳟鱼的影响。我们还表征了欧洲鲈鱼大脑中的褪黑激素受体，并展示了其每日变化。（M. Iigo）7.单尾香鱼在自食条件下呈昼夜摄食模式。评估了触觉和光纤传感器对该种属的可用性。（K. 8. casino自食尼罗罗非鱼的皮质醇水平较低。自投鱼在巨噬细胞吞噬活性、抗体生成和血液循环淋巴细胞数量方面均显著高于投饵鱼。（M. Endo）9.虹鳟鱼更喜欢平衡的氨基酸饮食，而不是不平衡的饮食或无蛋白质饮食。最初脂肪鳟鱼减少他们的能量摄入量相比，最初瘦鳟鱼。（T. Yamamoto）减
