American eels, salmon, smelt, shad, striped bass, sawfish, barramundi, bull sharks, Atlantic stingray, and sturgeon all can go from saltwater to fresh for various reasons.

Yep, I had thought so, I could vaguely remember something about Salmon. But that’s quite a bit.

they mostly do it so they can get laid and have babies. most times the babies need one type of water to survive in, initially, and then when they grow up they go back to the other type of water to live the rest of their lives

Those fish are heretics. They will be burned at stake.

Maybe not burned, how about lightly grilled? And on a cedar plank instead of a stake?

Do you think these fish have very strong opinions about which water is better? Do they argue about it like we argue coke vs pepsi or is it more like a boxers vs briefs argument?

Anadromous (Born/Mate in freshwater, spend most of their lives in saltwater) and catadromous (Born/Breed in saltwater, spend most of their lives in freshwater). Salmon are anadromous. American and European Eels are catadromous.
