Resumo: The effect of food and photoperiod on dorado (Salminus brasiliensis) post-larvae growth and survival was investigated using the following treatments: LD (Light: Dark) 24:0 + Artemia nauplii (A), LD 24:0 + fish prey (F), LD 14:10 + A, LD 14:10 + F, LD 0:24 +A and LD 0:24 + F. Prochilodus lineatus larvae were used as fish prey. Higher survival rates were registered in fish prey treatments (P<0.05) and were not influenced by photoperiod whereas in Artemia treatments, the survival was very low, but directly proportional to light increase (P<0.05). The better growth in LD 0:24 was related to a safe-energy strategy that reduced energy consumption whereas in LD 24:0, the higher energy consumption reduced the growth. In intermediate photoperiod, the post-larvae did not define a strategy to capture preys, using alternatively the static safe-energy and the swimming consuming energy, which caused higher heterogeneity in growth.
