ABSTRACT. 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.
