| Outline of Final Research Achievements |
At first, we conducted to analyze functional evaluation of the fishway using check-list that Gifu Prefecture carried out investigations and improved the fishway that did not function concretely. Furthermore, in the low weir of water surface difference, we developed the siphon-pipe-fishway that fish could migrate to upstream. Under condition of around 2m for water surface difference, it was demonstrated that fish migrate. We analyzed microsatellite DNA of fish (Gnathopogon elongatus) to grasp the continuity of the stream-agriculture waterway network. As a result,
because there was the area where a genetic divergence suddenly changed in the same waterway, we examined the conservation plan of the fish habitat background using analyzed the factor.
