Smallmouth Bass

The Smallmouth Bass are medium-sized, deep-bodied fish, with green to olive back and sides, and yellow to white belly. Their bodies often have dark vertical broken bars, with 9 – 11 dorsal fin spines, a shallow notch between dorsal fins, and an upper jaw that does not extend beyond the eye. 

The Smallmouth Bass can grow between 25 cm – 50 cm, with a weight of 0.5 – 1.6 kilograms. The Ontario record for biggest Smallmouth Bass is 4.5 kilograms.

These fish can be found in the Great Lakes watershed, the St. Lawrence River, and northward beyond Lake Nipissing. In recent years they have been introduced into many areas of Northwestern Ontario. The Smallmouth Bass like to live in clear, rocky lakes and rivers, along shoreline rocks and points, offshore shoals, and in deep water. They have a similar habitat to that of the Trout, but with a wider range of temperatures.
