Migratory Fish

Migratory fish are essential to healthy river ecosystems. The Connecticut River hosts 8 species of migratory fish that travel thousands of ocean miles and over 200 miles upriver annually.

CRC's migratory fish restoration efforts include advocating for and expanding fish passage and raising awareness through community science and education.
