I don't actually know anyone who has ever had a musky in a pond, so my comment about the musky was not based on experience. But I have raised trout with my father in both a spring he dug out along the woods, and in my grandparents farm pond with large mouth bass and blue gill. If you have 20"+ large mouth bass so big you can stick your fist in their mouth, they will easily eat 12" trout like candy. What kind of bass do you have?
We stocked about 30 trout in the large farm pond, and within two years none of them were ever seen or caught again. The trout probably averaged in the 10" range when they were stocked, and there are lots of big large mouths in the pond.
Here is something I found by just doing a simple Google search on the musky. Maybe this will help:
Predator Pond Like 'em with teeth and plenty of muscle? Well, don't rule out small ponds if you want to establish a predator pond.
Even though much is still to be discovered about managing predators in small waters, it appears large predators such as musky and pike are viable management options for small, cool water ponds. While results remain varied, some pond managers are growing amazingly large predators in relatively small ponds.
When considering musky or pike, please realize these critters eat lots of forage,
so in a 1- to 2-acre pond there could only be a few adult sized predators, maybe fewer than ten. Such small numbers can create a problem not generating enough timely return for pond owners. Pond owners may not even see their prized pond dwellers for years, especially when you embrace the fickle nature of a muskellunge.
Although large musky or pike can eat just about any fish, forage remains the ultimate problem. Small bass and bluegill are perhaps the easiest forage for pond owners to grow, but members of the Esox family prefer soft rayed forage such as suckers, trout or even creek chubs. In parts of the country where spring fed ponds are common, trout make excellent forage for musky or pike. The point of emphasis is for pond owners to utilize whatever resources are available near their location. Since suckers and creek chubs are preferred food sources for musky, my favorite example of a predator impoundment comes from a pond owner who transformed an old beaver pond into a one acre farm pond.
Primarily filled with creek chubs, the pond owner searched for a manageable solution which would create a sport fishery from an existing forage base of chubs. I suggested musky, and after stocking two 30-inch male musky into the pond, the pond owner eagerly waited for some indication of his management strategy.
It wasn't until two years after initially stocking muskies he caught a 38 incher from the pond, twice in fact, during the same month. The following year he landed a 42 incher from the pond. Male musky don't get much larger than 40 inches, so these fish had likely attained maximum length. Note that stocking fish of the same sex helps prevent overpopulation of top predators in small ponds. Wonder how large female muskies could have grown in his small pond?
