Cytogenetic analysis of ten specimens of Pseudoplatystoma fasciatum revealed a diploid number of 2n=56 chromosomes and FN=88, without chromosomal differentiation between sexes. The karyotype was composed by 20 metacentric, 12 submetacentric, 12 subtelocentric, and 12 acrocentric chromosomes. The nucleolar organizing regions were located in a terminal position on the short arm of a subtelocentric pair. Constitutive heterochromatin was observed as small blocks in the terminal position of eleven chromosome pairs and in the pericentromeric position of about three chromosome pairs. A comparison with the available data is presented.
