Bought a house last spring that has two ponds equaling about 3/4 of an acre. All we were able to catch out of it was tiny tin brim and tiny catfish. Didn't catch anything larger than my hand. Caught no bass. I'd like to turn one into a bass pond and the other a catfish or Crappie pond. Can I stock bass fingerlings with our them being eaten by the other fish or do I need to do a chemical kill off? Any info you have would be helpful. I'm pretty clueless.
