Structural analysis of embryogenesis ofLeiarius marmoratus(Siluriformes: Pimelodidae)
Zygote, 2014SummaryEmbryological studies in fish species are useful to the understanding of their biology and systematics. The available biological data inLeiarius marmoratusare scarce and additional information about its reproductive biology is needed, mainly because this species has been commercially exploited and used in production of hybrid lineages.

Pimelodidae family is one of the most diverse and widely distributed fish groups in South America. Phylogenetic analysis in the family have recently indicated the existence of two main clades: "sorubiminae" and the OCP clade, including Pimelodus ornatus, "calophysines" and "pimelodines." The aim of this study was to investigate the karyotype of three ...

Supernumerary chromosomes in a Rhamdia hilarii population (Pisces, Pimelodidae)
Genetica, 1990A study was conducted on the chromosomes of a Rhamdia hilarii (Pisces, Pimelodidae) population. The results suggest that the basic chromosome number is 2n=58, with numerical variation up to a limit of 2n=63, due to the presence of supernumerary chromosomes which seem to be mitotically stable.

Larval ontogeny of the long-whiskered catfish Pimelodus blochii Valenciennes, 1840 is described, providing useful characters for identification and determining the growth pattern throughout its development. Eighty-nine larvae classified in three stages (preflexion, flexion and postflexion) and 30 juveniles were analyzed, totaling 119 individuals.
