Bass, perch
Stream-lined for high speed or swimming in currents
Brook trout, rainbow trout, arctic char

Carp, sucker
Fish more streamlined and fast-moving to catch prey
Northern pike, catfish, burbot
Colouration
Swims in open water
Walleye, goldeye
Hides in weeds for protection or to ambush prey
Perch, smallmouth bass, rock bass
Hides in rocks or on bottom
Northern pike, young sturgeon

Some of the adaptations that allow fish to live in the water are gills, fins, and scales. The gills allow the fish to live in the water. The gills allow the fish to extract oxygen from the water. The fins allow the fish to swim through the water and help it stear itself. For the scales I'm not sure!
