Resumo: This study's aim was evaluate the growth of silver catfish (Rhamdia quelen) fingerlings on five dissolved oxygen concentrations: 1,3 (T1), 2,4 (T2), 3,7 (T3), 5,4 (T4) and 7,5 mg O2/L (T5). A completely random design experiment with three repetitions was used and the experiment was carried out during 25 days. Fingerlings were distributed in circular, 150-L fiberglass tanks kept in darkness, endowed with mechanic and biological filters and water renewal, at a stocking density of 34 individuals/tank. Survival was lower at the extreme tested levels (T1 and T5). Better growth in weight, length and food conversion were found at increasing oxygen concentrations. Even at the lowest oxygen concentration (T1) fingerlings showed growth increase. The best effects on silver catfish fingerlings development was observed at T4

O estudo utilizou o modelo experimental inteiramente ao acaso com 3 repetições e foi conduzido por 25 dias. Os alevinos foram distribuídos em tanques circulares de fibra de vidro de 150 L mantidos na escuridão e dotados de aeração mecânica, filtro biológico e renovação de água, na densidade de 34 indivíduos/tanque. A sobrevivência foi menor nos extremos testados (T1 e T5). Maior crescimento em peso e em comprimento e melhor conversão alimentar foram obtidos com o aumento da concentração de oxigênio dissolvido. Os alevinos de jundiá apresentaram incremento em peso, mesmo na menor concentração de oxigênio dissolvido (T1), e T4 produziu os melhores efeitos sobre o desenvolvimentoUniversidade Estadual De Maringá2008-03-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/105710.4025/actascibiolsci.v28i1.1057Acta Scientiarum.
