“…The low anal fin ray count is indicative of the black rather than the brown bullhead (Table 1). In A. nebulosus it ranges from 21 to 24, usually 22-23, whereas in A. melas it is 17-20, usually 18-19 (Hubbs 1926, Scott and Crossman 1973, Wheeler 1978. In specimen MIZ 212734 the count is 20, while in the other two specimens (MIZ 212733, MIZ 212735), it is 21 and 22, respectively (Table 1).…”

“…Nonetheless, at least one of them (MIZ 212734, 95.0 mm SL) appears to have been identified incorrectly. Based on its main meristic (Hubbs 1926, Scott and Crossman 1974, Wheeler 1978 and qualitative features (Nowak et al 2010), it should be classified as A. melas (Table 1). Firstly, specimen MIZ 212734 has a fatty enlargement at the anal fin base which makes it poorly distinguished from the body; there are no such enlargements in A. nebulosus, in which the fin base is clearly divided from the belly (Nowak et al 2010).…”

Abstract. One specimen of the non-native ictalurid catfish the black bullhead, Ameiurus melas, was found in the collection of the Museum and Institute of Zoology of the Polish Academy of Sciences in Warsaw, Poland. This finding strongly supports the hypothesis that the black bullhead was co-introduced into Polish waters with the brown bullhead, Ameiurus nebulosus, at the end of the nineteenth century. The species might be distributed widely throughout Poland, thus careful investigation on the identity of the ictalurid catfish population throughout the country should be carried out.

“…Although the identity of wild European populations is uncertain, the black bullhead is the most widespread of the ictalurid species introduced into Europe (Wheeler, 1978), and has recently been recorded in Spain (Elvira, 1984) and Portugal (Gante and Santos, 2002). In Italy, the black bullhead first appeared in 1904 (Tortonese, 1970), and has now spread throughout most of the country.…”

The age and growth of the invasive black bullhead Ameiurus melas (Rafinesque, 1820) were studied in the Corbara Reservoir, an artificial lake located on the River Tiber in central Italy. The results of the research revealed that the population was made up of eight cohorts, the oldest specimens being spawned in 1999. The sex ratio appears to be balanced, although females predominate in the younger cohorts, while the percentage of males increases among older specimens. The differences between sexes in the slope of the length-weight relationship were not statistically significant; the slope for the whole sample (b = 3.055) was significantly greater than 3, indicating an allometric growth pattern of the black bullhead. There were no significant differences in mean back-calculated lengths at age between the sexes. Analysis of Lee's phenomenon revealed the existence of differential mortality among younger individuals (1 and 2 years old) that favours larger individuals. The Von Bertalanffy growth function was TL t = 35.69 {1 -exp[-0.18 (t + 0.27)]}. The specimens caught displayed mean relative weight (W r ) values distinctly below 100 at all ages, while no significant difference emerged between the sexes with regard to condition. RÉSUMÉCroissance du poisson-chat Ameiurus melas (Rafinesque, 1820) dans le Lac Corbara (Ombrie -Italie) L'âge et la croissance du poisson-chat invasif Ameiurus melas (Rafinesque, 1820) ont été étudiés dans le Lac Corbara, un lac artificiel situé le long du cours du fleuve Tevere, en Italie centrale. Les résultats de la recherche ont révélé que la population était composée de huit classes d'âges, les spécimens les plus âgés provenant de la fraie de 1999. Le sex-ratio semble être équilibré, bien que les femelles prédomi-nent dans les classes d'âges plus jeunes, tandis que le pourcentage de mâles augmente parmi les spécimens plus âgés. Les différences entre les sexes en matière de pente du rapport longueur-poids n'étaient pas significatives ; la pente de tout l'échantillon (b = 3.055) était significativement supérieure à 3, indiquant que le poisson-chat a un modèle de croissance allométrique. Aucune différence significative n'a été constatée entre les longueurs rétromesurées moyennes des différents sexes au même âge. L'analyse du phénomène de Lee a révélé l'existence d'une

“…Since its first introduction in France in 1871, this species has spread widely all over Europe (Wheeler 1978;Novomeska and Kovac 2009). This omnivorous fish inhabits low-gradient streams with turbid waters and silt bottoms and can survive in heavily polluted water with high temperatures (Simon and Wallus 2004).…”

Mitochondrial DNA sequence revealed contrasting demographic history between the black bullhead (Ameiurus melas) and its cryptic lineage in North America

-The black bullhead, Ameiurus melas of the family Ictaluridae, is a freshwater fish native to North America that was introduced throughout Europe in the late 1800s. Using mitochondrial DNA (mtDNA) as a genetic marker, the present study investigates the genetic structure and historical demography of A. melas in North America. MtDNA-based phylogenetic analyses revealed the existence of two distinct lineages (A and B) of A. melas. While lineage A clustered with the previously reported sequences of A. melas, lineage B emerged as a unique clade like other species of the genus Ameiurus. Individuals belonging to lineage B were mostly from the south central region of the United States, the region that never glaciated during the last Ice Age. Results of a fossil-based molecular clock analysis suggest that lineage A and the paraphyletic lineage B of A. melas diverged from their respective common ancestors approximately 3 (±0.2) and 15.9 (±1.3) million years ago. Lineage B could possibly be a hybrid species, possessing the mtDNA haplotype of its maternal parent, an Ameiurus species that has gone extinct. While lineage A showed evidence of population expansion, lineage B did not show any evidence of population expansion, but rather is comprised of geographically structured populations.
