AbstractThe spotted surubim Pseudoplatystoma corruscans is a large migratory catfish native to the La Plata and San Francisco basins. Nonetheless, its reproductive dynamics and behaviour remain poorly understood. This brief note provides the first record of the mating behaviour of P. corruscans in natural conditions.

This paper describes the results of our initial studies with hybrid surubim catfish leucocytes and suggests that the techniques used may have further application. According to size, shape, staining patterns and ultrastructure, five blood leucocyte types were identified in the peripheral blood of surubim: lymphocytes, thrombocytes, monocytes ...

Abstract The aim of this study was to investigate the effects of different salinities and prey concentrations on Pseudoplatystoma corruscans, Prochilodus costatus and Lophiosilurus alexandri larviculture. For each species, the larvae were reared at a density of 15 larvae/l in 27 2-l aquaria. The experiments were conducted in a 3 × 3 factorial design,

A physical chromosome mapping of the H1 histone and 5S and 18S ribosomal RNA (rRNA) genes was performed in interspecific hybrids of Pseudoplatystoma corruscans and P. reticulatum. The results showed that 5S rRNA clusters were located in the terminal region of 2 chromosomes. H1 histone and 18S ribosomal genes were co-localized in the terminal portion of
