Migratory fish species: living between the sea and the river Of the more than 32,000 fish species known to science, 58% live in the sea, 41% in freshwater, and less than 1%, the so called diadromous fish, occur in both ecosystems, at different stages of their life cycle. Diadromous proved a useful word, but terms proposed by Myers for other types of diadromous fish did not catch on. These included amphidromous (fish that migrate from fresh water to the seas, or vice versa, but not for the purpose of breeding), potamodromous (fish whose migrations occur wholly within fresh water), and oceanodromous (fish that Diadromous fish migrate between fresh and marine waters to complete their life history.

Historically, diadromous fish contributed to the sustenance and economic growth of the Atlantic states. However, since the industrial revolution the tolls of environmental stress, overfishing, and habitat loss were to become apparent in the longest settled parts of the country (Field 1914, Oviatt et al. 2003). Diadromous fish are a species group that includes both anadromous and catadromous fish. Anadromous fish, such as the American Shad Diadromous fishes There are only 7 freshwater fish species that occur in Iceland and all are either diadromous (that is, they migrate between freshwater and saltwater) or have diadromous origins. Diadromous fishes describe species that spend part of their lives in freshwater and part in saltwater. There are two categories of diadromous fishes, catadromous and anadromous.

Yet it has frequently produced mixed results and diadromous fishes remain at very low levels of abundance. Against this background, this paper presents the main challenges Diadromous species, such as the Salmonidae and Anguillidae, which undertake large-scale migrations through coastal and offshore waters, are already significantly affected by other human activities leading to national and international conservation efforts to manage any existing threats and to minimize future concerns, including the potential effect of MRED.
