Resumo: The experiment verified the development of Iguaçu´s surubim (Steindachneridion sp.) larvae, submitted to different diets in darkness. 35L-aquariums were used, in a completely randomized design, with five treatments and four repetitions. Each aquarium had 15 larvae with 8,35±0,85 mm and 6,75±0,64 mg, and the treatments were the following diets: Artemia(A); ration(R); zooplankton(Z); Artemia+ration(A+R); and zooplankton+ration (Z+R); After 29 days, the treatments A+R and Z+R was 1036 mg and 859 mg, respectively, significantly higher (P < 0,01), that A and Z, with 536 and 270 mg, respectively. In the treatment R there was no larvae survival, and presented high cannibalism (71%), which was also observed in other treatments, in smaller rates. This results led to the conclusions that the association of live and artificial diets in darkness provided best development, but it does not reduce the cannibalism.

Foram utilizados aquários de 35 litros, em um delineamento inteiramente casualizado, com cinco tratamentos e quatro repetições. Colocaram-se 15 larvas por aquário, com 8,35±0,85 mm e 6,75±0,64 mg. Os tratamentos foram as dietas: Artemia(A); ração(R); zooplâncton(Z); Artemia+ração(A+R); e zooplâncton+ração (Z+R). Após 29 dias, os resultados mostraram que os tratamentos A+R e Z+R obtiveram pesos médios finais de 1036 e 859 mg, significativamente maiores (p < 0,01), que A e Z, com 536 e 270 mg, respectivamente. No tratamento R não houve sobrevivência de larvas, e apresentou alta taxa de canibalismo (71%), o qual foi também observado nos outros tratamentos, em menores taxas. Pode-se concluir que a associação de alimentos vivos e dietas artificiais em ambientes escuros apresenta bom desenvolvimento mas não reduz o canibalismo.UEL2005-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/227410.5433/1679-0359.2005v26n1p109Semina: Ciências Agrárias; Vol. 26 No. 1 (2005); 109-116Semina: Ciências Agrárias; v. 26 n. 1 (2005); 109-1161679-03591676-546Xreponame:Semina.
