The review, published in Biological Reviews, finds that dams are reducing the populations, species diversity, and genetic health of diadromous species – fish, eels, crabs and snails that depend ...

Diadromous fish (such as sturgeon, salmon, shad, eels, lampreys, mullets), whose life cycle alternates between fresh and salt water, are major contributors to aquatic biodiversity and to the ...

In fact, only 55% of the modelled core habitats of diadromous fish fell within any MPAs, and of these protected areas, only had half had specific measures to protect the species.

Diadromous fish, which include river herring (blueback herring and alewife), American shad, American eel, and sea lamprey, are fish that depend upon passage between marine and freshwater habitats ...

It has also been the scene of drama for diadromous fish — which migrate between the salty waters of the sea and fresh waters inland — cutting them off from important breeding habitat upstream.

We examined the status of diadromous (migratory between saltwater and freshwater) fishes within the North Atlantic basin, a region of pronounced declines in fisheries for many obligate marine species.

Newly born shad, still attached to their egg sacks, are being stocked in the Taunton River, allowing them to gain an “imprint on the unique characteristics of the river,” MassWildlife said.

In fact, only 55% of the modelled core habitats of diadromous fish fell within any MPAs, and of these protected areas, only had half had specific measures to protect the species.
