What I normmaly do is just collect my fish food, by growing what I can, or catching what I can.
Shrimping ( normmaly get about 10 bucket fulls when we go )
I go salt water fishing once a month and catch baitfish, and other large fish witch get falayed ( spelling lol )
I go to a sloughter house and get beef heart for cheap
