Evaluación de la calidad de agua en el sistema de permacuaponía en los estanques de la institución agrícola Guacavía, Cumaral meta.

Abstract

Fish farming is the raising and cultivation of aquatic species in both freshwater and marine environments in a water circulation system, while permacuaponics is the combination of a fish and vegetable production system. The water quality of two systems, one of permacuapony and the other of traditional fish production at the Guacavía Agricultural Educational Institution, was evaluated because the water quality of the system and the discharge is affected by the fish farming activity due to the waste of nutrients from the food, since the fish ingest 70% or 75% of it, becoming a residue high in nitrogen and phosphorus compounds, so that changes in the physicochemical parameters of the water are generated. For this purpose, the analysis of the water quality parameters of the influent and the production ponds was carried out on the basis of 10 samples taken from each pond over a period of 2 months. As a result, the water quality parameters of the pond with the permacuaponics system showed an improvement in the water as opposed to the traditional fish production system, due to the fact that the phosphate parameters decreased by 40% and nitrates by 65%. The electrical conductivity was in a very low range, however, it increased by 23%.
