Genetic Variation of the Endangered Neotropical Catfish Steindachneridion scriptum (Siluriformes: Pimelodidae) [PDF]

Frontiers in Genetics, 2018
Steindachneridion scriptum is an important species as a resource for fisheries and aquaculture; it is currently threatened and has a reduced occurrence in South America. The damming of rivers, overfishing, and contamination of freshwater environments are the main impacts on the maintenance of this species.

Chromosome Polymorphism in Species of the Pimelodidae Family (Pisces, Siluriformes) [PDF]

Hereditas, 2004
Cytogenetic studies of three species of the Pimelodidae family were carried out. The results showed a diploid chromosome number of 2n = 46 for Pimelodellu spl, 2n = 52 for Pimelodellu sp2 and 2n = 50 for Pinirampus pirinumpu. Chromosome polymorphism was detected by of G-banding analysis in Pimeladella spl and by C-banding in P. pirinampu.
