Bone Lake is primarily managed for Walleye (WAE). Annual fingerling stocking at the rate of 1.0 pounds/littoral-acre (124.0 lbs) has occurred since 1982. The catch of walleye was greatly reduced in 2012 from the previous investigation, and only 1 fish of "keeper" size was sampled. The catch rate of northern pike was similar to earlier investigations, but the size of the pike sampled was much larger (6.6 pounds average size) than earlier studies. The largest pike sampled exceeded 40" and weighed more than 14 pounds. Largemouth bass numbers sampled by electrofihing gear was more than twice the catch of the investigation conducted in 2006, with a good size distribution of fish sampled. The average size bass sampled was about 10", while 1/3 of the bass sampled were larger than 12". The largest bas sampled exceeded 18" and weighed just under 4 pounds. Yellow perch numbers increased in this investigation, but the size of perch sampled was small. The catch of black crappie increased, while the bluegill catch decreased. The size of both panfish species sampled was average for the area. Bullhead were sampled at historic low levels.

Recreational activities such as recreational boating, angling, waterfowl hunting, and diving may spread aquatic invasive species. Some aquatic invasive species can attach to boats, while others can become tangled on propellers, anchor lines, or boat trailers. Many species can survive in bilge water, ballast tanks, and motors or may hide in dirt or sand that clings to nets, buckets, anchors, and waders. Fortunately, completing simple steps can prevent the transport of aquatic invasive species.
