Stenohaline

Stenohaline

Stenohaline describes an organism, usually fish, that cannot handle a wide fluctuation in the salt content of water. [ [http://www.ca.uky.edu/wkrec/VertebrateFishEvolution.htm Wurts, W. Why can some fish live in freshwater, some in salt water, and some in both? World Aquaculture 29(1):p.65.] ] Stenohaline is derived from the words: "steno" meaning narrow, and "haline" meaning salt. Many fresh water fish, such as goldfish ("Carassius auratus"), tend to be stenohaline and die in environments of high salinity such as the ocean. Many marine fish, such as haddock, are also stenohaline and die in water with lower salinity.

Alternatively, fish living in coastal estuaries and tide pools are often euryhaline (tolerant to changes in salinity) as are many species which have life cycle requiring tolerance to both fresh water and seawater environments such as salmon and herring.
