We release much of what we catch. Sometimes I just like to see how fast I can catch bluegill. In heavily stocked areas that are starting to stunt the bluegill we will keep some for dog food. We also use any fish that has swallowed a hook or gotten damaged as dog food. If we get a nice fish like that bass, which was the best tasting fish I've ever eaten, or some good catfish we'll keep them. For catfish we usually use a small clear pond so they are clean. Stocking is maintained by the city/county in these ponds that had to be built to handle the runoff from new construction so they put them to use. This city has trout stocked in a few streams that are fed from underground and so stay cool year round.
