The Warmouth

Warmouth is a deep-bodied sunfish with a relatively large mouth. Dark lines radiating behind the eye are useful identification features.

Range and Identity

Lepomis gulosus is retained as the scientific identity. Its large mouth and cheek markings should be considered with the whole fish rather than used alone. Similar sunfishes can occur in the same waterbody, and a common fishing nickname is not always a precise determination.

Habitat and Behavior

Adults occur in quiet vegetated waters, including ponds, lakes and slow stream habitat over soft bottom. Cover is useful habitat context. This does not mean that every nearby open-water or fast-current observation represents the same preferred setting.

Food and Life History

The compiled upper references are thirty-one centimeters total length and 1.1 kilograms. They are independent published measurements, not necessarily one specimen. Male care of the brood is reported; the exact duration varies with conditions rather than following one fixed number of days everywhere.

Field Note

Photograph the cheek pattern and full body as well as the mouth. A clear identification helps keep Warmouth records separate from other sunfishes and from unspecified hybrid observations.
