The Calico Bass (Pomoxys sparoides) is so called because of the mottled and variegated coloring of the body and fins. It is also called the Strawberry Bass, the Grass Bass, the Bitter Head, the Lamplighter and the Barfish.

It is abundant in all the lakes and ponds of the region of the Great Lakes and the upper Mississippi river, where it shows a preference for quiet, cool and clear water and grass covered bottoms.

The Calico Bass is closely related to the Crappie (Pomoxys annularis) of the lower Mississippi valley. It is, however, seldom seen where the Crappie is abundant, as the latter prefers muddy sloughs and bayous and is not found as far north as the former.

The body of the Calico Bass is elongated, is much compressed and of a bright, silvery olive-green color. The sides and fins are mottled with a darker green or brownish-green, the blotches being gathered into irregular bunches. The vertical fins also have markings in the form of a network surrounding paler spots. The mouth is large and oblique. The usual length of the adult is about twelve inches.

The Calico Bass obtains its food largely from the lower forms of animal life, such as crustaceans, worms and insects.

It is said that "from the fact that it thrives well in slow-moving waters, it deserves the favorable consideration of .owners of large mill ponds, where there is a steady flow of water, as it requires very little care, except the first planting of it in waters suitable to its nature. It is not averse to an occasional minnow, but is not regarded as peculiarly aggressive, though provided by nature with an armature that enables it to defend itself against all comers."
