In Wisconsin, we have the luxury (or curse, depending on your point of view) of shorter warmer seasons so our waterbodies can often support a certain array of fish. However, as your waterbody decreases in size and volume, the more “limited” the pond can be to the fish it can support. In general, the smaller the waterbody, the faster it can warm or cool. Often, Bluegill, Largemouth Bass, and Fathead Minnows make a great combination for smaller waters. As the size of the water increases, you tend to gain the availability for fish such as Black Crappie, Yellow Perch, Smallmouth Bass, Walleye, and Muskie or Northern Pike (and more).
Clients often inquire about various Trout species. Please keep in mind that trout require very high Dissolved Oxygen levels in addition to cool water temperatures. Water that reaches in the upper 60 degrees Fahrenheit range will cause some levels of stress for trout. The levels of stress will increase and lead to lack of growth/feeding and eventually death as the water temperature climbs into the upper 70’s and 80 degree Fahrenheit range. It is best to track your pond’s water temperature for a summer prior to stocking trout depending on your goals for the stocking.
