The okinaebisu was bred in an experimental tank at a fixed temperature and the water temperature was kept at 14℃ to 17℃. And we covered the box with a blanket for the purpose of shielding them. According to some records, the movement of the okinaebisu has been reported to be a nocturnal habit but the movement was relatively brisk both day and night, hence the movement is not always a nocturnal habit. The movement of the okinaebisu was not in a direction. That went zigzag at an average speed of 0.3cm per minute, but it was reported to be 2.0㎝ per minute in a short time. And according to our observations, the okinaebisu fed selectively on micro-organisms.From these results,the okinaebisu is considered to be carnivore (sarcop-hagy). The okinaebisu reacted unsatisfactorily against light but reacted relatively fast against flash light. The okinaebisu did not show a sensive reaction to sound.}, pages = {73--80}, title = {底刺網で採取したオキナエビスの飼育結果について}, volume = {8}, year = {1981} }
