抄録

1. The Tokoro River running over 51 km, near Abashiri in Hokkaido, was investigated in August 1961 at seven stations in regard to the influence of industrial pollution upon the bottom fauna.<BR>2. The main elements in the composition of the bottom fauna in question are insect larvae and nymphs which are composed of mainly those of caddis flies, mayflies and midges.<BR>3. The standing crop of bottom animals of each station examined was shown Tables 2 and 3. Its highest value was found at the station 1, Kunneppu, being amounted 4, 293mg per 50cm x 50cm of the river bottom. The lowest value, 39.3mg was found at the station 4, Wakamatsubashi, where the palp mill waste flows into the river.<BR>4. The biotic indices according to BEcK's (1955) method modified by TSUDA (1960) are shown in Fig. 2 and Tab. 4.
