Studies on fish appetite and its control.

1. 在模拟季节变化条件下成功养殖虹鳟鱼。研究了优势鱼的行为和社会特征。(m . Tabata) 2。采用新设计的光纤传感器，成功地饲养了红鲷鱼幼虫。除夏季外，成组红鲷均有不同季节的摄食规律。水温对主饲养峰有显著影响。（会田和古川）浮网笼中的黄尾鱼表现出每年黄昏加夜间的自食模式。它们与模拟的年度光周期同步良好。光是黄尾鱼主要的自食模式。(j . Kohbara) 4。通过internet进行远程控制，开发了自馈网络系统。该系统有几个功能；1)自动送料监控，2)显示和数据保存，3)送料控制。（市川、山下）自养虹鳟鱼的血糖水平在关灯时间较长时达到峰值。研究了自食和禁食组大鼠腹端脑对神经肽Y （NPY）的免疫反应性。(t . Oishi) 6。我们展示了温度和光周期对自养鳟鱼血浆和眼褪黑激素节律的影响。我们还描述了欧洲海鲈鱼大脑中的褪黑激素受体，并证明了其每日变化。(m . Iigo) 7。自食饲养时，单尾阿育鱼呈日采食模式。对触觉和光纤传感器的可用性进行了评估。(k . Yamamori) 8。尼罗罗非鱼的皮质醇水平较低。在巨噬细胞的吞噬活性、抗体的产生、血液循环淋巴细胞的数量等方面，自食鱼明显超过预定摄食鱼。(m . Endo) 9。虹鳟更喜欢氨基酸平衡的饮食，而不是不平衡的饮食或无蛋白质的饮食。最初，与最初瘦的鳟鱼相比，脂肪含量高的鳟鱼的能量摄入减少了。（山本）更少

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.
