Molecular and morphological approaches for species delimitation and hybridization investigations of two Cichla species Iheringia, Sér. Zool.
Mourão,Andrea A. F.; Freitas-Souza,Diogo; Hashimoto,Diogo T.; Ferreira,Daniela C.; Prado,Fernanda D. do; Silveira,Rosicleire V.; Foresti,Fausto; Porto-Foresti,Fábio.
ABSTRACT The hybridization is a widely-discussed issue in several studies with fish species. For some authors, hybridization may be related with diversification and speciation of several groups, or also with the extinction of populations or species. Difficulties to differentiate species and hybrids may be a problem to correctly apply a management of wild species, because hybrid lineages, especially the advanced ones, may resemble the parental species. The genus Cichla Bloch & Schneider, 1801 constitutes an interesting experimental model, considering that hybridization and taxonomic uncertainties hinder a correct identification. Considering these problems, in this study, we developed genetic methodologies and applied meristic and morphometric approaches...

Molecular identification of intergenus crosses involving catfish hybrids: risks for aquaculture production Neotropical Ichthyology
Hashimoto,Diogo T.; Prado,Fernanda D.; Foresti,Fausto; Porto-Foresti,Fábio.
ABSTRACT Monitoring of the interspecific hybrid production and trade is essential for the appropriate management of these animals in fish farms. The identification of catfish hybrids by morphological analysis is unreliable, particularly of juveniles and post-F1 individuals. Therefore, in the present study, we used five molecular markers (four nuclear genes and one mitochondrial gene) to detect hybrids in the trade of pimelodid juvenile fish from different stocks purchased of five seed producers in Brazil. Samples commercialized as pintado (pure species Pseudoplatystoma corruscans ) from three fish farms were genetically identified as hybrid cachapinta (♀ P. reticulatum x ♂ P. corruscans ). In the stocks purchased as cachandiá (hybrid between ♀ P....
