When Ayu-fries which were motored far from Lake Biwa to Ueda under a long and heavy confinement are set free in a culture pond, they begin to exhibit a type of jumping movement-we call it "Released jumping"-towards the cascade of the water entrance. This jumping behavior is seen from about 45 minutes before sunrise to about 35 minutes after sunset on a fine day, when four modal peaks of the activity are recognizable. The present activity compared with that of feeding which was observed by ISHIDA (1964) in a pond, the former seems to be in a regular reverse relation to the latter in each peak. The height of jumping is 62cm to 68cm on an average and the optimum current velocity for the activity is assumed to exist below 80cm/sec. Of the environmental factors, the sunlight intensity appears to be most influential, though it is considered that the activity is controlled primarily by some endogenous mechanism of the fish.
