Resumo: | The aim of the research was to evaluate the population growth of Moina sp. fed four diets for a period of 14 days. The initial density was one adult mill/L-1 of water. The mills were cultivated in 20 transparent plastic containers with a useful volume of 20L-1. The water temperature, pH, dissolved oxygen and electrical conductivity were checked daily. Four types of diets were tested and five samples of one liter were collected daily from each culture tank, where they were filtered through an 800µ sieve and the organisms placed in a 50mL container with the help of a pipette, for total counting under a stereomicroscope with magnification of up to 25x. The population parameters evaluated were: maximum density of organisms; day of maximum density; specific growth rate; doubling time and yield. The results were submitted to the F test for analysis of variance and linear regression analysis with the aid of the SAS® statistical package. The physical-chemical parameters of temperature, pH, dissolved oxygen and electrical conductivity remained within the recommended range for cultivation. However, for the population parameters of maximum density (diet 4) and population growth rate (diet 3), they presented statistical difference in relation to the other evaluated diets. The parameter Doubling time (Td) showed no significant difference between the evaluated diets. The most suitable diet for the cultivation of Moina sp. was treatment 4 which contained in its composition Microalgae Scenedesmus subspicatus, fermented fish feed, Aptamil premium and Yeast (Saccharomyces cerevisiae). |

La densidad inicial fue de un molino adulto / L-1 de agua. Los molinos se cultivaron en 20 recipientes de plástico transparente con un volumen útil de 20L-1. La temperatura del agua, el pH, el oxígeno disuelto y la conductividad eléctrica se controlaron diariamente. Se probaron cuatro tipos de dietas y se recolectaron cinco muestras de un litro diariamente de cada tanque de cultivo, donde se filtraron a través de un tamiz de 800µ y los organismos se colocaron en un recipiente de 50mL con la ayuda de una pipeta, para el recuento total bajo un estereomicroscopio con aumento de hasta 25x. Los parámetros poblacionales evaluados fueron: densidad máxima de organismos; día de máxima densidad; tasa de crecimiento específica; duplicar el tiempo y el rendimiento. Los resultados fueron sometidos a la prueba F para análisis de varianza y análisis de regresión lineal con la ayuda del paquete estadístico SAS®. Los parámetros físico-químicos de temperatura, pH, oxígeno disuelto y conductividad eléctrica se mantuvieron dentro del rango recomendado para el cultivo. Sin embargo, para los parámetros poblacionales de densidad máxima (dieta 4) y tasa de crecimiento poblacional (dieta 3), presentaron diferencia estadística en relación con las otras dietas evaluadas. El parámetro Tiempo de duplicación (Td) no mostró diferencia significativa entre las dietas evaluadas. La dieta más adecuada para el cultivo de Moina sp. Fue el tratamiento 4 que contenía en su composición Microalgas Scenedesmus subspicatus, pienso fermentado para peces, Aptamil premium y Levadura (Saccharomyces cerevisiae).O objetivo da pesquisa foi avaliar o crescimento populacional de Moina sp. alimentadas com quatro dietas por um período de 14 dias. A densidade inicial foi de uma moina adulta/L-1 de água. As moinas foram cultivadas em 20 recipientes plásticos transparentes com volume útil de 20L-1. Foi verificada diariamente a temperatura da água, pH, oxigênio dissolvido e condutividade elétrica. Foram testados quatro tipos de dietas e coletadas diariamente cinco amostras de um litro, de cada tanque de cultivo, onde as mesmas foram filtradas em peneira de 800µ e os organismos colocados num recipiente de 50mL com ajuda de uma pisseta, para contagem total sob estereomicroscópio com aumento de até 25x. Os parâmetros populacionais avaliados foram: densidade máxima de organismos; dia de máxima densidade; taxa de crescimento específico; tempo de duplicação e rendimento. Os resultados obtidos foram submetidos ao teste F para análise de variância e análises de regressão linear com o auxílio do pacote estatístico SAS®. Os parâmetros físico-químicos de temperatura, pH, oxigênio dissolvido e condutividade elétrica, se mantiveram dentro do intervalo recomendado para o cultivo. Entretanto, para os parâmetros populacionais de densidade máxima (dieta 4) e taxa de crescimento populacional (dieta 3), apresentaram diferença estatística em relação as outras dietas avaliadas. O parâmetro Tempo de duplicação (Td) não apresentou diferença significativa entre as dietas avaliadas.
