ABSTRACT

North African catfish C. gariepinus is of great commercial importance both in fisheries and aquaculture. In Poland it has been introduced for aquaculture purposes in early 90. However this is the first detailed description of the north African catfish population
cultured under condition of the heated water aquaculture in Poland. The objective
of the present work was to fill a gap in the knowledge on the African catfish
by examining in detail the morphometric characters.The material used to study
meristic and morphometric characters consisted of 100 individuals collected from
the rearing ponds, measuring from 9.0 to 26.0 cm in total length (TL), the mean
length being 18.1 cm. Taxonomic analysis involved 15 morphometric and 7 meristic
characters, including as well the relationships among them.

Key words: aquaculture, Clarias gariepinus, gill rakers, morphometrics, occipital process.
