E-mail: email@example.com The feeding in the larviculture of species carnivorous view point for closing of the technological packages of rearing culture. Developed in the sector of Aquicultura of the IFES - Campus of Alegre, this work it aimed at to compare the performance with four diet feed as first exogenous feeding for traíra (Hoplias malabaricus), parameters evaluated: Survival, length final (CF), final weight (PF), tax of specific growth (TCE), development tax specifies (TDE), being put in container with fifteen liters of water, with constant aeration, have five larva of traíra/container. The delineation entire was aleatory with four treatments and five repetitions. Being the diet feeds represented for T1: Nauplios de Artemia sp.; T2: microworm of oats (Pannagrelos redivivus); T3: Wild Zooplâncton; e the inert food represented by T4: Commercial ration in dust with 55% of crude protein and 4,200 Kcal de ED/kg of ration. The water exchange was of 80% daily, the average temperature was of 27.5±1°C. The indices of survival in the T1, T2, T3 and T4, had been 84%, 72%, 100% and 92%, respectively. The date had been submitted analyze it statistics ANOVA and test of Tukey (P<0.01). Wild Zooplâncton was biggest CTF, PF, GP, TCE and TDE. Did not have difference statistics between the Artemia sp. the ration for TCE and TDE. The microworm of oats was minor CF, PF, TCE and TDE. The treatment Wild zooplankton (T3) showed optimum diet food among the other diet feeds tested for the development and the survival of the larva of traíra, that in turn the treatment (T4) - the ration was adapts precociously, getting low mortality with the inert ration diet feed.
