| North America: Great Lakes to northern Mexico. Confusion over the taxonomic status of this species together with Ameiurus nebulosus resulted in more doubts as to which of the two is present in some countries. In Europe it forms dense stunted populations which makes it unpopular. Several countries report adverse ecological impact after introduction (Ref. 1739). In Europe, self-sustaining populations recorded from Ebro and Tagus drainages (Iberian Peninsula), most drainages of France, locally in Italy, the Netherlands and Germany; distribution could be wider (Ref. 59043) |

| Inhabits pools, backwaters, and sluggish current over soft substrates in creeks and small to large rivers; impoundments, oxbows, and ponds. Nocturnal feeder, young consume immature insects, leeches, and crustaceans while adults also feed on clams, snails, plant material, and fishes (Ref. 1998, 9669, 10294). Edible (Ref. 1998). Are susceptible of being caught, where they are abundant, with baited lines intended for other species. Is considered a nuisance (Ref. 30578). Often misidentified as A. nebulosus (Ref. 59043). |
