Long Island Migratory Fish Week

April 18 - 22, 2022

L.I. Migratory Fish Week

Celebrating the amazing diadromous fish that visit Long Island’s estuaries and streams, as well as the local efforts to restore their habitat.

We are excited to be celebrating Long Island Migratory Fish Week to highlight amazing diadromous fish that call Long Island home (at least part of the time).

Migratory fish, or more specifically “diadromous fish,” can be considered the marathon runners of the fish world! These amazing species travel hundreds, even thousands of miles in the course of their life-cycles, which are split between fresh and saltwater. Where most of the world’s fish live exclusively in either fresh or salt water (and would die if they were moved to the other), diadromous fish effortlessly move between the two habitats. The word diadromous come from the Greek “dia,” which means “through” and the root “dromous,” which means “running.” 

Diadromous fish play a vital role in coastal ecosystems. Their movement from salt to fresh water is essential in transferring ocean-derived energy into estuarine, freshwater, and upland habitats. In providing sustenance—like eggs, juveniles, and/or adults—for countless other species, they literally help to drive coastal and upstream food webs.
