Marine fishes can'tlive in freshwater because in the body
of marine fishes the concentration of salt is high and the
concentration of water is low.so the water molecules moves
from higher concentration to lower concentration.There is a
chance to swell the body of fish and burst by endosmosis
and die up.Fresh water fishes can't live in seawater.Because
through exosmosis the fish would die.

Generally speaking, no. Except a few, some of which are
migratory, marine fishes cannot survive in freshwater. This
is because the marine fishes are adapted to survive in water
with high salt concentration. If they are put in
freshwater, the low concentration of salt in freshwater
(hypotonic) causes entry of excess of water into their body
(endosmosis)which can lead to death of the animal.
Similarly most freshwater fishes cannot survive in salt
water because of exosmosis (loss of water from the body) due
to high salt concentration of sea water.
