Integrative morphometric and molecular analyses reveal possible genetic contamination of silver catfish populations of the genus Rhamdia in Neotropical River basins. [PDF]

J Fish Biol
Abstract Rhamdia quelen, Rhamdia branneri and Rhamdia voulezi are morphologically similar species that, until recently, were considered synonymous. Although R. quelen has wide distribution in the Neotropical region, R. branneri and R. voulezi are sympatric and endemic species of the Iguaçu River basin.

Influência da luminosidade no crescimento de Jundiá (Rhamdia quelen) / Influence of luminosity on the growth of Jundiá (Rhamdia quelen)

Brazilian Journal of Development, 2022
Esta pesquisa foi realizada com objetivo de avaliar o efeito da luminosidade sobre o crescimento de juvenis de jundiá. Foram utilizados 225 peixes (70,53±3,68g), distribuídos em 15 caixas de 500 L, em um delineamento inteiramente casualizado, alimentados três vezes ao dia com ração comercial contendo 36% PB e granulometria 1,5 mm, durante 45 dias.
