Distribution of Fishes in the Red River of the North Basin on Multivariate Environmental Gradients
Hiodontidae
Mooneye
Hiodon tergisus Lesueur, the mooneye, was collected by Woolman (1896) from the Red River at Moorhead and Grand Forks and the Red Lake River at Crookston, where it was common to abundant in the samples. It has been collected in the Red and Red Lake Rivers, the lower reaches of the Pembina, Sheyenne, and Otter Tail Rivers, and the Wild Rice River in Minnesota (Figure A5). The species has been present at 5% of stream sites sampled in the Red River basin since 1962; and it has been taken almost exclusively from reaches in the RRV ecoregion, where it has occurred at 11% of sites (Table 4). The mooneye has been less abundant in site collections than the goldeye, as most samples in the basin have contained only 1-7 individuals.
