Question

Migratory fishes are
(A) Eurythermal
(B) Homeothermic
(C) Stenohaline
(D) Euryhaline​

Answer 1

Fish usually migrate to feed or to reproduce, but in other cases the reasons are unclear. ... Some particular types of migration are anadromous, in which adult fish live in the sea and migrate into fresh water to spawn, and catadromous, in which adult fish live in fresh water and migrate into salt water to spawn.

Answer 2

Answer:

Migratory Fishes are (D) Euryhaline.

Explanation:

A)Eurythermal means the organism  can adjust to a wide range of temperatures.

B)Homeothermic means the organism can maintain a constant body temperature.

C)Stenohaline means the organism cannot adjust to a wide range of salinity.

D)Euryhaline means the organism can tolerate a wide range of salinity.

As here we are discussing the migratory fishes, which have the capacity to tolerate and adjust according to the various salinities of different water areas, so the migration can happen.
