Diadromous fishes comprise less than 1% of world fish fauna, but their value to humans far exceeds this portion. Many diadromous fishes such as salmons, sturgeons, and shads are not only economically important, but they also serve as crucial links for energy flow between fresh and marine environments ( Helfman 2007 ).

have shown that the presence of dams negatively affected diadromous species and that, for some species, the duration since dam construction was also a relevant explicative variable.

Diadromous fish.

While some diadromous fish species (e.g. salmonids, eel) are famous around the globe and highly valued, others attract far less attention from policy-makers, scientists, or stakeholders but are likely to make crucial contributions to complex marine, transitional, and freshwater ecosystems.

They regain their freshwater coloration when they reenter the freshwater environment. – Anadromous fish – Catadromous fish (eel) Fishes of the Gulf of Maine; NOAA Fisheries Marine and Anadromous Fish; Gulf of Maine KnowledgeBase; Maine Department of Marine Resources; Historically, diadromous fish contributed to the sustenance and economic growth of the Atlantic states. One example of this includes semelparous species that breed once and die, a common life history among diadromous fish that migrate between fresh and seawater. The most prominent organisms in this group are anadromous species namely two Agnathan genera of lamprey ( Petromyzon and Lampetra ), and such teleost fish as Pacific salmon ( Oncorhrynchus sp) and southern populations of American shad ( Alosa sapidissima ). There are several types of diadromous fish, differing in their specific migration patterns.

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.

This site was done as a school project. Learn more about that in our About Us section. Other examples. See also: Salmon run, Vertical migration, and Lessepsian migration. Some of the best-known anadromous fishes are the Pacific salmon species, such as Chinook (king), coho (silver), chum (dog), pink (humpback) and sockeye (red) salmon. These salmon hatch in small freshwater streams. George S. Myers defined the term diadromous to refer to fish that migrate between fresh and salt water.
