What is Potadromous fish?

Potadromous fish, which do not migrate to the ocean at any time during their life cycle, undertake specific movements and occupy certain habitats at different times of the year within these freshwater systems so that they minimise or avoid the challenging conditions.

Are sturgeons anadromous?

Atlantic sturgeon are anadromous fish—they are born in freshwater and then migrate to the sea and back again to freshwater to spawn. Most juveniles remain in their river of birth (natal river) for at least several months before migrating out to the ocean.

Parasitic lampreys are usually anadromous and spend about one to four years at sea before returning to fresh water to spawn. Anadromous lampreys return to fresh water in the fall and over- winter until spring when they spawn. Once they begin their migration to streams, lampreys do not feed.

Which of the following fish can adapt to both saltwater and freshwater?

Fish that can tolerate a wide range of salinity at some phase in their life-cycle are called euryhaline species. These fish, which include salmon, eels, red drum, striped bass and flounder, can live or survive in wide ranges of salinity, varying from fresh to brackish to marine waters.

Why do Salmons migrate?

After a second winter at sea, adults from many populations are large and mature enough to spawn, and they migrate back to freshwater areas to reproduce.

Which type of fishes are migratory?

Anadromous fish live in the sea and migrate to fresh water to breed. Their adaptations to conditions of different habitats are precise, particularly with regard to salinity of the water. Salmon (Salmo, Oncorhynchus) spawn in the cold, clear waters of lakes or upper streams.
