| 摘 要： | 在北海道知床半岛周边海域,用小型数据记录器监测细鳞大马哈鱼Oncorhyncus gorbuscha和大马哈鱼O.keta的回归游泳行为,探讨其与环境水温的关系。数据记录间隔时间为1 s,连续记录时间为226 h。于2008年8月至10月期间,在知床沿岸放流了带有数据记录器的洄游途中的大马哈鱼和细鳞大马哈鱼个体(分别为30尾和5尾),分别有13尾、3尾个体被捕获。研究表明:试验个体有一系列的上浮和下沉行为,并且频繁地回到表层水面,垂直移动中的深潜水是对表层高水温和暖流分层水中的一种适温调节行为。因此,尽管表层水温较高,性成熟后的大马哈鱼仍会回到表层水面寻找其产卵场所。

| Abstract: | The migratory swimming behavior of pink salmon Oncorhynchus gorbuscha and chum salmon Oncorhynchus keta were monitored to study the relationship between homing behavior and ambient temperature off the Shiretoko coast in Japan by micro data-loggers which were used to record the depth and the temperature simultaneously for 226 hours at a 1 s interval.Thirty chum salmon and five pink salmon homing adults with data loggers were released into off the coast of Shiretoko,Hokkaido,in Japan from August to October 20... |
