Question

Fish living in coastal estuaries are often stenohaline

• A. True
• B. False

Answer 1

The correct option is B False

Fish living in coastal estuaries and tide polls 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. Stenohaline organisms can tolerate only a small range of salinity for example goldfish.
