The following fishes new on the Polish market were analysed: the Nile perch (Lates niloticus), oilfish (Ruvettus pretiosus, named 'butter-fish' in Poland), the African catfish (Clarias gariepinus), and a pangasiid catfish (Pangasius hypophthalmus). Quantitative assays involved protein, fat, fatty acids, fat-soluble vitamins (A, E, D3), macro- and microminerals (calcium, phosphorus, magnesium, selenium, copper), as well contaminants, such as toxic metals (arsenic, mercury, cadmium, lead) and histamine. The fishes are characterised by a varied fat content, low - in relation to Baltic fishes - levels of omega-3 fatty acids, a high content of oleic acid, and a low concentration of toxic metals and histamine
