Research Abstract

We could obtain continuous data of swimming body axis, tail beat activity for two days from two coastal-migrating chum salmon in Otsuchi coast, Iwate in 1999 using micro-data loggers, which have never been successfully obtained in the past. Analysis of these data showed that salmon consumed more energy for ascent than descent and never control the air volume in the air bladder.
We also succeeded to obtain 51days continuous data of swim speed, swim depth and ambient temperature from a offshore-migrating chum salmon in July, 2000. We attached a micro-data logger to a salmon at mid south of Bering Sea and recovered at coast of Nemuro city of Hokkaido. Preliminary analysis suggested that salmon swam at a mean speed of 36.2km/day. This means 2427km of swim distance in total during 51days, which occupied 80% of total 2760km of horizontal distance from release point to recaptured point.
We also conducted data-logger experiment on 30 trout, Oncorhynchus nerka, at Chuzenji Lake in 1999 and 2000 and successfully obtained data of swim depth and ambient temperature from 23 fish. From experiments we expected behavioral and temperature-physiological difference in their performance between condition of gonads of both sex. Data are under analysis.
