| 内容記述 | In 1992, red tides occurred in Hirono Dam reservoir, which locates upstream of Hino River, and then its water quality was presumed to affect the fishing of sweetfish(Plecoglossus altivelis)in the river. In this study, the water environment of Hirono Dam reservoir and Hino River was investigated for the last quarter century. It was found that the water quality has been slightly improved. Also, the fish fauna and the number of sweetfish caught in the river were examined. A limited kind of fish was found based on DNA analysis. The weight of sweetfish caught yearly has been declined, and social factors, such as population decrease, appear to influence the decline significantly. | |||||
