Distribution of Fishes in the Red River of the North Basin on Multivariate Environmental Gradients
Percidae
Logperch
Percina caprodes (Rafinesque), the logperch, was collected by Olson
(1932) from the Red Lake River above Crookston, but was not found by other
earlier investigators (Figure A72). The logperch has been taken almost
exclusively from the Otter Tail River, where it has occurred from the mouth at
Breckenridge to the headwater reaches in the NLF ecoregion. There are also
records from the Red, Pembina, Goose, Pelican, Red Lake, and Clearwater
Rivers; but the species has not been common in these streams. The logperch
has been taken at only 6% of the stream sites sampled in the Red River basin
since 1962, but has been most abundant in the NCH ecoregion, where it has
occurred at 19% of sites (Table 4). Typical collections have contained 3-5 individuals, but as many as 44 have been taken from the Otter Tail River at
Phelps, and 98 individuals have been taken at sites below the Orwell Dam in
glacial Lake Agassiz beach ridge reaches.
