(adjective) Ecological Significance of Diadromous Fish Species Diadromous fish have historically played a critical ecological role throughout the range of their habitats. For example, in freshwater, adult shad and river herring returning to spawn are assumed to be food for other fish, reptiles (e.g., snakes and turtles), birds Worldwide, fish are impacted by numerous river modifications including flow regulation (Lévêque et al. 2008). Fish species that rely on unique habitats have specialized diets or exhibit obligate life-history strategies (e.g. diadromous fish), and are especially Identification of Diadromous Fish Species on Which to Focus River Restoration: An Example Using an Eco-Anthropological Approach (The Seine Basin, France) (Eric Rochard, Patricia Pellegrini, Julie Marchal, Mélanie Béguer, Dominique Ombredane, Géraldine Lasalle, Erwan Menvielle, and Jean-Luc Bagliniere) Fisheries :: Fish Migration: Home: Fish migration. Many types of fish migrate on a regular basis, on time scales ranging from daily to annual, and over distances ranging from a few meters to thousands of kilometers.

They are biologically fascinating, and many of them support important sport or commercial fisheries. The phenomenon of diadromy was the focus of a 1986 symposium sponsored by the AFS Northeastern Division.

Anadromous fish live as adults in the sea but breed in freshwater, where juveniles usually stay for a time after hatching. Catadromous fishes are the opposite; adults live in fresh waters but migrate back to the ocean to breed. Our sturgeon research is generating valuable information on diet, which has been lacking in the South, and collecting samples for genetic comparison of fish from various rivers.
