Resumo: | Effluents from conventional intensive aquaculture, based on high water exchange, may strongly contribute to the acceleration of eutrophication processes, due to the significant nutrient load present in unconsumed foods and excreted waste. On the other hand, there are intensive and super-intensive systems for the cultivation of aquatic organisms that use water exchange associated with strong aeration and biological transformation of macronutrients. Such sustainable systems use the bio-addition of friendly microorganisms to increase the rate of degradation of macronutrients and maintain water quality. A mathematical adjustment was used in this study to verify the dynamics of organic matter, nitrogen and phosphate during the experiment period. A pulse dynamic at regular times occurred indistinctly for all indicators evaluated in this study, although the intensity of the pulses showed particularities among the different indicators of water quality. Although the behavior of regular pulses of the indicators occurred, this condition did not affect the growth of fish subjected to a simulated system of intensive production associated with the bio-addition of friendly microorganisms. |

Por otro lado, existen sistemas intensivos y superintensivos de cultivo de organismos acuáticos que utilizan intercambios de agua asociados a una fuerte aireación y transformación biológica de macronutrientes. Estos sistemas sostenibles utilizan la bioadición de microorganismos amigables para aumentar la tasa de degradación de macronutrientes y mantener la calidad del agua. En este estudio se utilizó un ajuste matemático para verificar la dinámica de la materia orgánica, el nitrógeno y el fosfato durante el período del experimento. Una dinámica de pulsos en tiempos regulares ocurrió indistintamente para todos los indicadores evaluados en este estudio, aunque la intensidad de los pulsos presentó particularidades entre los diferentes indicadores de calidad del agua. Si bien se presentó el comportamiento de pulsos regulares de los indicadores, esta condición no afectó el crecimiento de los peces sometidos a un sistema simulado de producción intensiva asociado a la bioadición de microorganismos amigables.Efluentes da aquicultura intensiva convencional, baseados em altas trocas hídricas, podem contribuir fortemente para a aceleração dos processos de eutrofização, devido à significativa carga de nutrientes presente nos alimentos não consumidos e resíduos excretados.

Effluents from conventional intensive aquaculture, based on high water exchange, may strongly contribute to the acceleration of eutrophication processes, due to the significant nutrient load present in unconsumed foods and excreted waste. On the other hand, there are intensive and super-intensive systems for the cultivation of aquatic organisms that use water exchange associated with strong aeration and biological transformation of macronutrients. Such sustainable systems use the bio-addition of friendly microorganisms to increase the rate of degradation of macronutrients and maintain water quality. A mathematical adjustment was used in this study to verify the dynamics of organic matter, nitrogen and phosphate during the experiment period. A pulse dynamic at regular times occurred indistinctly for all indicators evaluated in this study, although the intensity of the pulses showed particularities among the different indicators of water quality. Although the behavior of regular pulses of the indicators occurred, this condition did not affect the growth of fish subjected to a simulated system of intensive production associated with the bio-addition of friendly microorganisms. |
