Para verificar o desenvolvimento de larvas de surubim-do-iguaçu (Steindachneridion melanodermatum) alimentadas com diferentes dietas, realizou-se um experimento em delineamento inteiramente casualizado, com cinco tratamentos e quatro repetições, em aquários de 35 L, cada um com 15 larvas (8,35±0,85 mm e 6,75±0,64 mg). Os tratamentos consistiram de cinco programas de alimentação: A - Artemia; R - ração; Z - zooplâncton; A+R - Artemia + ração; Z+R - zooplâncton+ração. Avaliou-se o desenvolvimento das larvas em ambiente iluminado durante 29 dias. Para avaliação da dieta e análise do conteúdo estomacal, a cada três dias foram coletadas larvas em cinco aquários adicionais. Nos tratamentos A+R e Z+R, os pesos médios finais das larvas foram significativamente maiores (659 e 571 mg) que nos outros tratamentos. A combinação de alimentos possibilitou os melhores resultados e, no tratamento R, a sobrevivência foi de 1,7%, diferindo dos demais. O canibalismo foi superior no R e no Z, que apresentaram taxas de 60 e 25%, respectivamente. O fornecimento de Artemia em associação à ração promoveu melhor desenvolvimento e maior sobrevivência às larvas de Steindachneridion sp. An assay was conducted to evaluate the development of Iguaçu surubim (Steindachneridion melanodermatum) larvae fed different diets. The experiment was analyzed as a complete randomized design with five treatments and four replicates, in 35 L-aquaria, each one with 15 larvae (8.35±0.85 mm and 6.75±0.64 mg). The treatments consisted of five feeding programs: Artemia (A); diet (D); zooplankton (Z); Artemia with diet (A+D); and zooplankton with diet (Z+D). Larvae development was evaluated in illuminated environment during 29 days. For larvae feeding evaluation, three larvae were collected every three days, in five additional aquaria for stomach content analysis. In the A+D and Z+D treatments, the larvae average weight (659 and 571 mg) was significantly higher than the other treatments. The combinations of feeds resulted in better results and, in treatment R, it was observed survival rate of 1.7, that differs from the other treatments. Cannibalism rate was higher in D and Z treatments, with values of 60 and 25%, respectively. The A+D treatment provided the best development and the highest survival rate for Steindachneridion sp larvae
