Research on the Aquatic Community in Akaiyachi Mire and its Surround Areas, Fukushima Prefecture

Abstract

To evaluate the wetland conditions and the environmental preservation of Akaiyachi mire, faunal composition and seasonal changes of fish and other aquatic animals were investigated in a Akaiyachi mire and its surround areas in Fukushima Prefecture from 2003 to 2004. In this investigation, aquatic animals were invisible to the naked eye in the wetland. In contrast, some fish species and many aquatic animals such as insects were collected from the surround areas of wetland. Our investigations indicate that the water conditions are difference between the wetland and the surround areas. The information on the aquatic community in the surround areas also may be important for the environmental preservation of Akaiyachi mire.
