There are several species of redhorse, including the black, golden, river, shorthead, silver, and greater (pictured above). All are members of the sucker family, as are the white sucker, quillback, and the various species of buffalo fish (such as the bigmouth buffalo), and all are native to Minnesota lakes and rivers. Redhorse, like other members of this family, are bony but edible, and are especially good pickled. Though these species are considered undesirable rough fish and are generally not pursued by anglers, the DNR does keep records for many members of the sucker family. In case you're interested, the records for some of the species listed above are as follows: greater redhorse, 11-13; white sucker, 9-1; quillback, 6-14; and bigmouth buffalo, 41-11 (Minnesota DNR, 2000).
