We are trying take away the causes of the extinction, for example, many dams stop ITOs swimming up and down the streams. Since 2006, we have been collaborated with Shiribeshi Subprefectural Office of Hokkaido Government to build special fishladders for ITOs on 5 dams in Kudosan River, one of the tributaries of Shiribetsu River, and on spring 2009, we will achieve 3 of 5.
