Etymology: Ameiurus: Greek, a = without + Greek, meiouros, -os, -on = without tail (Ref. 45335); melas: Ameiurus (Greek) meaning privative curtailed (referring to the caudal fin lacking a notch); melas for black (Ref. 79012).

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)
北美洲: 五大湖到墨西哥北部。 在這種的分類狀態上的混淆伴隨著 Ameiurus nebulosus 關於那一個兩者是有些種類有國家造成更多的懷疑。 在歐洲，它形成使它不受歡迎的密集的成長受了妨礙的族群。 引入後的一些國家報告不利的生態衝擊。

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).

Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼
The female prepares the nest by clearing debris, gravel and silt found on the bottom. Before spawning, the pair engages in butting and in sliding its barbels over the body of the other. The female releases her eggs after the male wraps his caudal fin around the head of the female. The pair can spawn up to five times in an hour. In between spawning, the female fans the eggs. Both male and female guards and fans the eggs.北美洲: 五大湖到墨西哥北部。 在這種的分類狀態上的混淆伴隨著 Ameiurus nebulosus 關於那一個兩者是有些種類有國家造成更多的懷疑。 在歐洲，它形成使它不受歡迎的密集的成長受了妨礙的族群。 引入後的一些國家報告不利的生態衝擊。
