Are Tuna Freshwater Or Saltwater Fish

Question

Answer

Why can’t tuna live in freshwater?

Saltwater fish can’t survive in freshwater because their bodies are highly concentrated of salt solution (too much for freshwater). The water would flow into their body until all their cells accumulate so much water that they bloat and die eventually.

Does tuna come from salt water?

Tuna comes from the salty sea water, meaning you can’t get it completely without salt. You can, however, get a “no salt added” variety to keep your sodium intake to a minimum. Plus, you can prep it at home to get rid of a little more of the salt and further reduce your sodium intake.
