First record of the black bullhead Ameiurus melas (Teleostei: Ictaluridae) in Poland
Journal of Fish Biology, 2010The North American catfish, the black bullhead Ameiurus melas, is recorded for the first time in Poland. The origin of these fish is not clear, but their presence may be associated with unregulated introductions by anglers.

Environmental Biology of Fishes, 2004Common names: Neosho madtom (T). Conservation status: Listed federally as threatened 22 May 1990 (USFWS 1991). Identification: One of 25 madtom species, distinguished from four madtoms in its range by two distinct crescent-shaped bands of pigment on caudal fin and lack of dark pigment extending to edge of adipose fin (Taylor 1969). Pectoral spines have

Range Extensions for Three Species of Madtoms (Noturus: Ictaluridae) in Kansas
Transactions of the Kansas Academy of Science (1903-), 1989Collections of fishes from the Neosho River system in Kansas included apparent range extensions for three species of madtoms. On 4 September 1988, three freckled madtoms, Noturus nocturnus Jordan & Gilbert (MHP 2075; KU 22169), and one Neosho madtom, Noturus placidus Taylor (MHP 2068), were captured with a seine from a gravel riffle 0.25 mi.

Reproductive Traits of the Neosho Madtom, Noturus placidus (Pisces: Ictaluridae)
Transactions of the Kansas Academy of Science (1903-), 1994Reproductive traits of the Neosho madtom, Noturus placidus, were studied in the Neosho River in east-central Kansas, and in static and flow aquaria from May through July 1992. Artificial substrata were placed in riffle and pool areas of the Neosho River, and in simulated riffle and pool environments in our laboratory.

Cell and Tissue Research, 1981
Scanning electron microscopy of vascular corrosion replicas and light microscopy revealed a pair of highly vascularized tissues, the carotid labyrinths, in the dorsal head region of the channel catfish, Ictalurus punctatus, the black bullhead, I. melas, and the walking catfish, Clarias batrachus.

Histochemistry, 1981
Alkaline phosphatase and peroxidase activities were investigated in typical neutrophils and in vacuolated cells, the latter considered to be another type of neutrophil in catfish blood. This study was carried out by light- and electron-microscopy. Two lines of neutrophils were recognized in the peripheral blood of catfish. Alkaline phosphatase activity
