Resumen
El presente estudio se realizó con el objetivo de evaluar el crecimiento de la especie Piaractus brachypomus bajo dos sistemas de producción diferentes, suministrándole en su dieta 5% de harina de soya hidropónica, empleándose un Diseño completamente al Azar con 3 grupos (Tratamiento T1, Repetición T2 y Testigo T) en tanques y 2 grupos (T1 y T) en piscinas de tierra. Esta investigación se realizó con 275 juveniles de Cachama, distribuidos 25 en cada tanque y 100 en cada piscina, con un peso inicial de 2.7g y un tamaño promedio de 3.5cm, realizando muestreos en cada tanque (5 peces) y en cada piscina de tierra (15 peces), cada 10 días durante los 90 días de estudio, para medir significancias estadísticas se utilizó el software Infostat y por medio de la prueba de Duncan se realizaron los análisis de las variables de estudio por medio del cual se establecieron altas significancias estadísticas para las variables peso, talla y conversión alimenticia. Al final de la investigación se reportó una tasa de crecimiento diaria de 2.52g(T1), 2.18g(T2), 1.79g(T) en tanques y 3.34g(T1), 2.88g(T) en piscinas, presentando conversiones alimenticias entre 1.73 y 3.20, con una mortalidad del 5%. Por tanto, se recomienda el uso de harinas de origen vegetal como la soya (HSH) en la dieta de los peces para mejorar los parámetros productivos durante la etapa de cultivo.
The present study was carried out with the aim of evaluating the growth of the species Piaractus brachypomus under two different production systems, supplying it with 5% hydroponic soybean meal in its diet, using a completely randomized design with 3 groups (Treatment T1, Repeat T2 and Control T) in tanks and 2 groups (T1 and T) in ground pools. This investigation was carried out with 275 juvenile Cachama, distributed 25 in each tank and 100 in each pool, with an initial weight of 2.7g and an average size of 3.5cm, sampling in each tank (5 fish) and in each ground pool (15 fish), every 10 days during the 90 days of study, to measure statistical significance the Infostat software was used and by means of the Duncan test the analyses of the study variables were carried out by means of which high statistical significance was established for the variables weight, size and food conversion. At the end of the study, a daily growth rate of 2.52g(T1), 2.18g(T2), 1.79g(T) in tanks and 3.34g(T1), 2.88g(T) in pools was reported, with feed conversions between 1.73 and 3.20, with a mortality rate of 5%. Therefore, the use of vegetable-based meals such as soybean (HSH) in the fish diet is recommended to improve production parameters during the cultivation stage
