People have studies (not many) on adding salt to a freshwater diet. (In the food, not in the water.)
Amounts up to 4% have some potential benefits, but as one gets close to 4%, it negatively impacts growth and dilutes other food ingredients. (It reduces protein absorption, imo likely because the kidneys --- in humans at least --- are negatively affected by a surplus of either salt or protein.)
Salted fish is at least 7% salt, so, I think that means salted fish should not be a staple.
This isn't to say like feeding unsalted marine fish as a diet. Marine fish (e.g., halibut, tuna, shark) have very low salt contents of under 1%.
Also, each species reacts to salt differently, so there's a risk whenever one provides a large amount of foreign diet ingredient to an animal that evolved without it. I'd say fresh fish is the way to go.
