In northern climates, largemouth bass may live to be 18-20 years old.
Hybrid bluegills are a sterile cross between a bluegill (Lepomis macrochirus) and a green sunfish (Lepomis cyanellus). This hybrid attains a larger size and exhibits more robust growth than either parent. Because they are sterile, hybrids won’t overpopulate a pond like true bluegills.
Fathead minnows lay their eggs on the underside of floating objects, such as logs and lily pad leaves. Fathead minnow spawning can be enhanced in your pond by adding a few floating boards.
Walleyes spawn on windswept rocky shorelines or on flooded vegetation in river bottom marshes, thus they seldom successfully spawn in small lakes and ponds.
Aeration can prevent winter fish kills. It will also increase the fish carrying-capacity of your pond, as well as fish growth rates.
Yellow perch, bluegill and crappie feed heavily on the larvae of mayflies, caddisflies, midges and other insects. A non-aerated pond typically lacks sufficient oxygen in the depths to support a healthy insect forage base
