抄録

Effects of sewerage system improvement on profiles of benthic animal in Seno River which domestic wastewater was discharged were investigated from 1998 to 2000. Improvement was carried out 2000 to 2003. From 1998 to 2005, pollution index, bio index, diversity index and p.p index were improved about 2, 3, 2.5 and 1.6 times, respectively. The improvement of water quality in Seno River due to the sewage system development was suggested by the evaluations of biotic indices such as pollution index, bio index, diversity and p.p index.
