Abstract
This study clarifies the fanction of the fish habitat and temporal change in fish fauna and environmental factors in a wand-channel and wand-pool which were constracted in the river of an urban area. The investigation was carried out from 1996 to 2008 in the lower reach of the Edo-River, its wand-channel and wand-pool.
As a result, Pseudorasbora parva, Oryzias latipes latipes and Gambusia affinis which were small and resident fish, inhabited in wand-channel and wand-pool. It was suggested that Cyprinus carpio and Carassius spp. spawned and the juvenile grew in there. Otherwise, the fanction deteriorated because of shallowing of water depth. However, it was suggested that the fanction restored by re-excavation. It was thought that demonstrating the factor that influence on inhabiting and spawning of the fish in wandchannel and wand-pool was hereafter issue.
