Largemouth Bass   
Diet: Crustaceans, fish, frogs, aquatic invertebrates
Habitat: shallow lakes, ponds, rivers
Conservation Status: Non-threatened
Range: Southeastern Canada; USA: Great Lakes area, south to Gulf of Mexico; introduced in other areas of USA and in Europe and Africa
Scientific Name: Micropterus salmoides

A member of the sunfish family, the largemouth bass is usually greenish and silvery in coloration, with a dark band along each side; its dorsal fin is divided almost in two by a notch. A predatory fish, it feeds on crustaceans and other invertebrates when young, gradually progressing to fish, frogs and larger invertebrates when mature. Spawning takes place in spring or early summer, depending on temperature and latitude. The male excavates a nest in sand or gravel in shallow water and attracts a female to his nest to lay her eggs, usually a few hundred. The male fertilizes the eggs and may then attract more females to his nest. The sticky-surfaced eggs attach themselves to the bottom of the nest and are guarded by the male until they hatch, 7 to 10 days after laying.

Lake Trout   

Diet: Fish, insects, crustaceans, plankton
Habitat: lakes, rivers
Conservation Status: Non-threatened
Range: Canada, Northern USA
Scientific Name: Salvelinus namaycush

One of the most important commercial freshwater fishes and a popular sport-fishing species in North America, the lake trout is actually a char, not a true trout. It has now been successfully introduced into lakes out of its natural range. A beautiful fish, it has characteristic pale spots on head, back and sides. Lake trout feed on fish, insects, crustaceans and plankton. From late summer to December, lake trout spawn in shallow, gravel-bottomed water. There is no nest, but males clear the spawning ground of debris. The eggs are laid on the gravel and settle among the stones; they remain there for the winter and hatch in early spring.
