THE HERRING RUN

River Herring are anadromous fish, like salmon, which spend the majority of their lives in salt water, but return to the rivers and streams to spawn. Fish ladders (like this one in Oak Bluffs, Ma.) enable herring to rest in pools as they climb to the fresh water, and bypass roads, dams, and other obstructions to their progress.
