Check around your local golf course's as D-nymph stated.I stocked my pond with all sorts of gold fish/koi from a local golf course..Paid $1-$3 A FISH. Had to catch em myself,(Hint) take your fishing pole & bread. Got bite figured out caught extra & sold them to a pet shop $3-$5 a fish. Some up to 10 inches, but where stunted due to over population. 5 years later some of those fish are 5-6+lbs.
