The carbon and nitrogen stable isotope ratios of the fishes in the coastal area of Kagawa Prefecture were measured. The fishes ware collected in the coastal areas of Kanonji, Aji, and Hiketa. The nitrogen stable isotope ratios differed in each area. The nitrogen stable isotope ratios of the fishes belong to the planktonic food-chain were similar in each areas. On other hand, for the fishes belong to the benthic food-chain, the nitrogen stable isotope ratios of Hiketa and Aji areas was higher than it of Kanonji area about three par mil. This result indicates that in Hiketa and Aji, the organic matter with the high nitrogen stable isotope ratio, such as the feed used in fishery culture and the organic matter produced in the eutrophic river, is supplied to the bentic food chain.
