    Anadromous Fish Conservation Act, United States 2009

  • Although the term "anadromous" refers only to those fish that spawn in freshwater and live most of their lives in saltwater, it is often used interchangeably with "diadromous."

    Anadromous Fish Conservation Act, United States 2009

  • Fisheries for arctic freshwater and diadromous fish are conducted in all polar countries including Canada, Denmark (Greenland), the Faroe Islands, Finland, Iceland, Norway, Russia, Sweden, and the United States (Alaska).

    Impacts on arctic freshwater and anadromous fisheries 2009

  • About 30 species within the arctic regions belonging to the families Petromyzontidae, Acipenseridae, Anguillidae, Clupeidae, Osmeridae, Salmonidae, and Gasterosteidae exhibit diadromous behavior (i.e., spend part of their lives in the marine environment and migrate to freshwater to spawn, or the converse).

    Effects of climate change on arctic anadromous fish 2009

  • Freshwater fisheries as described here include those for species that live their entire lives in freshwater, such as lake trout, and those for diadromous species such as Atlantic salmon.

    Impacts on arctic freshwater and anadromous fisheries 2009

  • Most arctic diadromous species are actually anadromous (i.e., use estuarine and/or marine environments for feeding and rearing; and freshwater environments for spawning, early life history, and, in the case of most arctic species, overwintering); only freshwater eels (Anguillidae) and some lampreys (Petromyzontidae) are catadromous (i.e., breed at sea and rear in freshwater).
