Karyotype variability in neotropical catfishes of the family Pimelodidae (Teleostei: Siluriformes)

Neotropical Ichthyology
Karyotypic data are presented for four species of fish belonging to the Pimelodidae family. These species show a conserved diploid number, 2n = 56 chromosomes, with different karyotypic formulae.

Técnica de videoceloscopia para sexagem em surubim (pseudoplatystoma coruscans x pseudoplatystoma reticulatum) [PDF]

, 2011
The surubim (Pseudoplatystoma spp.) is a priority specie for the development of national aquaculture. The absence of sexual dimorphism makes it difficult to determine the gender, becoming reproductioninaccurate, and individuals need to keep for 2 to 3 ...

Feeding of larvae of the hybrid surubim Pseudoplatystoma sp. under two conditions of food management - doi: 10.4025/actascibiolsci.v35i2.15359

Acta Scientiarum: Biological Sciences, 2012
We evaluated the growth and diet composition of hybrid surubim larvae (Pseudoplatystoma corruscans x P. reticulatum) produced in two fish farming by using different systems of feeding with natural plankton: M I, larvae are transferred to fertilized fish ...
