The Tahoe Sucker

Tahoe Sucker is associated with the Lahontan basin and is frequently found in large lakes. It also occupies pools in lower stream reaches.

Range and Identity

Catostomus tahoensis is recorded in the Lahontan basin of southeastern Oregon, Nevada and northeastern California. Upper Sacramento occurrences have been described separately, with uncertainty about natural establishment versus introduction. That distinction should remain attached to those records rather than becoming a blanket native-range extension.

Habitat and Behavior

Adults occupy several habitat types but are especially associated with large lakes, including Tahoe and Pyramid. Pools along lower stream reaches are also documented. A lake-centered description is useful, provided it does not erase the stream habitat included in the account.

Food and Life History

The reported maximum is sixty-one centimeters total length, while 27.5 centimeters is a common reference. The checked summary does not establish an independent maximum mass or detailed diet and spawning sequence. Those particulars are not transferred from another western sucker.

Field Note

Preserve the drainage and collection setting with a record. A familiar lake name does not establish that every nearby river or reservoir contains the same identified population.
