Tuna

Tuna is a food that is fairly popular among free to players, as it can heal 10 per unit, and since the fishing spot isn't very far from a lesser demon area where people train, it can be a useful food. You can use it in potatoes to make a better healing food. It requires 35 fishing to catch, and 30 fishing to cook. Free to players find them annoying when fishing for swordfish, because they are caught along with the swordfish. It is still a powerful and cheap healing tool though, and can be very useful when a weaker alternative is present.
