We perform the naturalized species extermination in Shirokita wand as a base of the environmental conservation of Yodogawa and keep Acheilognathus longipinnis in good condition. It is desirable to monitor an inhabiting fish phase to show an effect of the naturalized species extermination. In this report, We compare the fishing with a seine fish phase detection by a capture investigation and the environmental DNA analysis to depend in Shirokita wand and report the result that considered about a utilization method to future monitoring.
