Resumo: The aim of this study was to evaluate the survival and the growth of surubim Pseudoplatystoma corruscans larvae in five stocking densities: 15, 35, 55, 75 and 95 larvae/L, distributed in a completely randomized design with three repetitions. Brackish water (5%) was used in the cultivation. The larvae were cultivated without light and fed with 500 Artemia sp. nauplii/larvae/day. At the end of the experiment (10th day), the survival showed tendency to reduction with the increase of the stocking density, but a relationship between growth and density was not registered. The concentrations of non-ionized ammonia and nitrite varied proportionally to density increase and those concentrations probably influenced the final survival. The highest survival (52.0 ± 9.3%) was registered at 15 larvae/L, a density that did not produce negative effect on the quality of water.

Utilizou-se água salinizada (5%) para o cultivo. As larvas foram mantidas em ambiente sem luz e alimentadas com náuplios de Artemia sp. na proporção de 500 náuplios/larva/dia. Ao final do experimento (10o dia), a sobrevivência apresentou tendência de redução com o aumento da densidade de estocagem, mas não se verificou relação entre o crescimento e a densidade. As concentrações de amônia não ionizada e de nitrito apresentaram variação diretamente proporcional ao aumento da densidade e podem ter influenciado a sobrevivência final. A maior sobrevivência (52,0 ± 9,3%) foi registrada em cultivo com 15 larvas/L, sendo que essa densidade não produziu efeito negativo sobre a qualidade da água.Editora da Universidade Estadual de Maringá2008-02-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/65310.4025/actascianimsci.v28i2.653Acta Scientiarum.
