Range and Identity
Percopsis omiscomaycus has a broad Canadian and northern United States distribution, including Yukon, Great Lakes and Mississippi drainage areas. The identity belongs to a distinct fish species. Its common name should not be interpreted as evidence of parentage involving two other fish families.
Habitat and Behavior
Adults use lakes and deep flowing creek or river pools, usually over sand. In lakes they move into shallows at night and return deeper toward dawn. This daily movement differs from a long seasonal migration between separate river basins.
Food and Life History
The upper reference is twenty centimeters total length, with 8.8 centimeters as common. Foods include insect larvae, amphipods and small fishes. Spawning fish move into shallow lake margins or tributaries; timing within the day varies among populations.
Field Note
Keep time of day and water depth with an observation. A nighttime shallow-water catch and a daytime deeper record may describe normal daily habitat use by the same species.
