Larvicultura semi-intensiva de sábalos (Prochilodus lineatus) con diferentes regímenes alimenticios

Abstract

Con el objetivo de obtener una mejor tasa de crecimiento y sobrevivencia garantizando una buena calidad y cantidad de alevinos, en el presente trabajo se comparó el crecimiento y la supervivencia de larvas de P. lineatus sometidas a tres regímene salimenticios diferentes en larvicultura semi-intensiva durante 29 días. Los estanques fueron fertilizados con estiércol bovino para la producción de alimento natural (AN) e identificados como tratamiento uno (T1) solo AN, T2 AN más alimento balanceado (AB) con 28% de proteína bruta (PB) y T3 AN más AB con 32% de PB. Se utilizaron estanques de cemento con una densidad de 100 larvas/m2, las cuales fueron alimentadas tres veces por día, registrándose parámetros de oxígeno y temperatura dos veces por día. Al culminar la experiencia se verificó el peso final y la tasa de sobrevivencia. Los tratamientos T2 y T3 registraron los mayores pesos finales, no encontrándose diferencias para la tasa de sobrevivencia.

With the purpose of obtaining a better rate of growth and survival guaranteeing a good quality and quantity of alevins, this case has compared the growth and the survival of P. lineatus larvae while exposed to three different alimentary regimes during 29 days of semi-intensive larviculture. The ponds were fertilized with bovine manure to produce natural food (AN) and were identified as treatment one (T1) only AN, T2 AN more balanced food (AB) with 28% of gross protein (PB), T3 AN more AB whit 32% of PB. Concrete ponds were utilized with a density of 100 larvae/m2. They were fed three times per day and oxygen and temperature parameters were registered twice a day. At the end of the experiment middleweight and survival rate were measured. T2 and T3 had a higher middleweight, no difference was found on their survival rate.
