Would be a good idea :0 all you need to pay for is bait to get more fish. And you don't get fish on every bait you use. Hmmmm maybe once you catch the fish you cook it yourself, possibly put a cooking level? So the higher the level the better the fish restores your hp, or the less it burns so you have a chance to get more edible fish that you catch. Not sure, of course sell the raw fish for a good price. Just some ideas I guess.

Of course be sure it's a no pk zone, would make the job easier.
