How long would a saltwater fish live in freshwater?

Question

for example if i put a fish i caught outta the ocean into a lake how long would it live?

Answer 1

A few minutes. It's not a matter of suffocating, it's the chemical imbalance: in the ocean, the fish's body has to get rid of salt, while in freshwater it has to retain the salt. Some fish, like salmon, are able to switch, but they have to spend several days in the transition zone before heading out to sea or back up the river.

Answer 2

Not long.How long would you live without air?
