Vertebrados consumidos por Brycon opalinus (Pisces, Characidae) em rios do Parque Estadual da Serra do Mar, SP [PDF]
Biota Neotropica, 2006 A análise da alimentação da pirapitinga do sul (Brycon opalinus), peixe ameaçado de extinção de rios da Mata Atlântica da Serra do Mar na região Sudeste, revelou a ocorrência de itens alimentares incomuns. As espécies deste gênero são onívoras oportunistas e alimentam-se de itens vegetais e animais, tais como: flores, folhas, frutos e sementes e grande

Crescimento e mortalidade de Brycon opalinus (Characiformes, Characidae) no Parque Estadual da Serra do Mar, Mata Atlântica, Estado de São Paulo [PDF]
Biota Neotropica, 2007 Os parâmetros de crescimento e mortalidade de machos e fêmeas de Brycon opalinus foram estimados de janeiro a dezembro de 2004 em rios do Parque Estadual da Serra do Mar - Núcleo Santa Virgínia (SP). As distribuições das freqüências nas classes de comprimentos totais foram diferentes para machos e fêmeas. Os parâmetros estimados para os machos e fêmeas

Theriogenology, 2012 The objective was to develop a suitable freezing method to cryopreserve Brycon opalinus (Characiformes) sperm. Extenders (NaCl and glucose at 325 and 365 mOsm/kg), cryoprotectants (dimethyl sulfoxide=dimethyl sulfoxide (DMSO) and methyl glycol=methyl glycol (MG)), equilibration times (15 and 30 min), thawing temperatures (30 and 60 °C), and straw sizes

Aquaculture, 2011 AbstractSperm preservation is an important tool for conservation of endangered fish species, such as the Brycon opalinus (Characiformes). An optimum medium should prevent the initiation of sperm motility during storage. The aim of this paper was to study the effects of extender composition, osmolality and cryoprotectant agent (CPA) on the motility of B.
