Aquaculture, 2002 Abstract RFLP analysis of mitochondrial DNA was carried out to investigate the population genetic structure of cultured and wild populations of Pirapitinga-do-sul— Brycon opalinus (Cuvier, 1819) (Characiformes, Characidae, Bryconinae) from the Paraiba do sul basin, Brazil.

Aquaculture, 2005
Abstract The genetic structure of Brycon opalinus (Brazilian freshwater fish species) from seven wild populations across Paraiba do Sul basin and one cultured population was investigated using 7 microsatellite loci. Polymorphism at all loci was assessed with a total of 162 different alleles found.

Ovarian development of fishes involves significant functional and structural changes during the process of mature egg formation. In this study, we report the folliculogenesis and follicular growth in the endangered species Brycon opalinus as well as the dynamics of the proteins Foxl2, Col4 and MMP-9 during ovarian maturation.

Molecular Ecology Notes, 2003
Abstract Brycon species are present in various basins in Brazil and were or still are part of commercial fisheries and aquaculture activities (Ferreira et al. 1996, Mendonça 1994). Despite the importance of this group of fish, natural populations of some Brycon species are endangered (Lins et al. 1997).
