Resumo: Abstract - An experiment lasting 180 days was carried out to evaluate the influence of sex on the performance and production of silver catfish (Rhamdia quelen) when reared in closed recirculation systems using only males, only females, or with both genders. A total of 300 fish (41.49 ± 6.82 g and 16.53 ± 0.95 cm) were used, comprising 150 females and 150 males distributed in an experimental structure consisting of three closed water recirculation systems coupled to a 20,000 L culture tank and a 20,000 L biofiltration tank connected by a 3,500 L h-1 water pump. The first system contained 100 females, the second, 100 males, and the third, 50 females and 50 males. High fish weight variations were observed regardless of sex. Female weight gains and specific growth rates were 41.51 % and 28.94 % higher compared to males, respectively, exhibiting greater growth than males raised monosexually or in mixed rearing systems, with no effect on chemical composition or trunk yield. The findings thus indicate that both male and female silver catfish exhibit wide weight variations and females that gain more biomass than males reared monosexually or in mixed-sex systems.

Foram utilizados 300 peixes (41,49 ± 6,82 g e 16,53 ± 0,95 cm) sendo 150 fêmeas e 150 machos distribuídos na estrutura experimental, que constava de três sistemas fechados de recirculação de água, com um tanque de cultivo e um tanque de biofiltragem, ambos de 20.000 L de capacidade e ligados por uma bomba d’água de 3.500 L h-1. O primeiro sistema foi composto por 100 fêmeas, o segundo por 100 machos e o terceiro por 50 fêmeas e 50 machos. Os peixes, independente do gênero, apresentaram uma grande variação de peso. O ganho de peso e a taxa de crescimento específico das fêmeas foram, respectivamente, 41,51 % e 28,94 % superiores aos machos. Fêmeas de jundiá apresentam um crescimento superior a machos criados de maneira monossexual ou mista, sem efeito sobre a composição química ou rendimento do tronco. Esta espécie apresenta ampla variação de peso, independente do sexo, a criação de fêmeas pode apresentar um melhor ganho de biomassa que a criação de indivíduos machos ou mista.Departamento de Diagnóstico e Pesquisa Agropecuária.
