I am building a pond about 2000-3000 gallons this spring. Approx 4ft deep, 10 ft length and width. I will be stocking it with many native fish including- largemouth,smallmouth, walleye, sunfish, albino Catfish, crappie, and perch. I will only buy one or two of each fish. I will purchase these fish from a hathery all about the same size. It would be too expensive for me to feed these fish exclusively live fish, worms etc. What do you suggest will be the best food to feed these fish.
