Range and Identity
Ambloplites rupestris occurs in selected St. Lawrence, Great Lakes, Hudson Bay and Mississippi basin waters. Introduced populations also occur outside North America. Its bass common name does not place it in the black-bass genus Micropterus, and similar Ambloplites species require careful identification.
Habitat and Behavior
Adults use rocky shallows in lakes and streams, plus vegetated or brushy margins. Clear rocky streams are common habitat, while introduced European populations also use slower waters. A single regional account should not be treated as the only habitat pattern across all populations.
Food and Life History
Upper references are forty-three centimeters total length and 1.4 kilograms. Foods include crustaceans, insects and small fishes. Males fan and defend shallow nests and care for offspring. A nest can receive eggs from more than one female rather than representing a fixed lifelong pair.
Field Note
Include the rocky or brushy shelter in a habitat note. Cover can explain the fish’s location within an otherwise open stream or lake margin.
