Abstracts

Cathorops sp has the diploid number of 54 chromosomes. The karyotype comprises lm + sm, 6m, 6sm and 14st pairs. This result is compared with those of other species of Ariidae, mainly Ariopsis felis and Arius dussumieri, found in literature.

Foram realizados estudos cromossômicos em 25 espécimens de Cathorops sp pelo método de air-drying. O número modal diplóide encontrado foi de 54 cromossomos sendo 1 par m + sm, 6 pares m, 6 pares sm e 14 pares st. Os resultados são comparados com dados da literatura referentes a cromossomos de outros ariídeos, principalmente de Ariopsis felis e Arius dussumieri.
