          Abstract

          Se realizó un ensayo de alimentación para evaluar el efecto de 28, 32 y 36% de proteína cruda en concentrados comerciales extrusionados sobre el crecimiento de alevines de bagre yaque, Leiarius marmoratus. Un total de 180 alevines (20,3 g) fueron dispuestos en 12 jaulas (0,5 m³), con cuatro réplicas por tratamiento. Las jaulas se distribuyeron al azar en cuatro tanques (2,0 m³), a razón de tres jaulas/tanque. Cada tanque se dotó con flujo continuo de agua (1,5 L/min), aireación y drenajes independientes. Los concentrados fueron administrados a saciedad aparente durante 40 días. No se encontraron diferencias significativas en la tasa de crecimiento instantáneo (TCI), tasa de alimentación diaria (TAD), índice de conversión del alimento (ICA), coeficiente térmico de crecimiento (CTC) y coeficiente de eficiencia proteica (CEP) en los alevines alimentados con concentrados de diferente nivel proteico. La TCI correspondió a 1,80%/d. La TAD fluctuó de 2,34 a 2,6% PV/d, el ICA entre 1,33 y 1,5, el CTC entre 0,667 y 0,712 y el CEP varió de 2,08 a 2,4. Los niveles proteicos estudiados tuvieron el mismo efecto sobre el crecimiento, conversión del alimento, tasa de alimentación diaria, coeficiente térmico de crecimiento y coeficiente de eficiencia proteica en alevines de Leiarius marmoratus.

          Translated abstract

          An experiment was conducted to evaluate the effect of dietary protein level on growth performance of bagre yaque, Leiarius marmoratus, fingerlings fed with three commercial extruded diets. Fish (20.3 g) were placed in twelve 0.5 m³ cages at a density of 15 fish per cage. Groups of three cages were placed inside each of four 2 m³ interior tanks. Three commercial diets or treatments (28, 32, and 36% crude protein) were randomly assigned to cages inside each interior tank to adjust to a completely randomized block design with four replicates. Each interior tank was provided with continuous water flow (1.5 L/min), aeration and independent drains. Diets were provided at apparent satiety for 40 days. At the end of the experiment there were no significant differences (P >0.05) on specific growth rate (SGR), daily feed consumption (DFC), daily feed conversion ratio (FCR), thermal growth coefficient (TGC), and protein efficiency rate (PER) of fingerlings fed the three commercial diets. SGR was 1.8%/d. The DFC varied between 2.34 and 2.6% BW/d, FCR was between 1.33 and 1.5, and PER varied between 2.08 and 2.4. The protein levels studied had the same effect on growth, feed conversion rate, daily food, and protein efficiency ratio on fingerlings of Leiarius marmoratus.
