AVALIAÇÃO DA PRODUÇÃO DE TILÁPIA (Oreochromis niloticus) CULTIVADA EM AQUAPONIA PILOTO UTILIZANDO ÁGUAS NÃO TRATADAS

Evaluation of Tilapia (Oreochromis niloticus) production cultivated in pilot aquaponics using untreated water

Abstract

To ensure water security, they must enforce the use of water. Aquaponics, which is a form of sustainable creation that works by recirculating treated water through biological filters. This work aimed to quantify the biomass production of fish cultivated sources using aquaponics systems. For this, data were collected in two periods, one using water from the rainy season and the other from the dry season. Three treatments were installed with water from different sources (public supply, artesian well and stream) and each one was populated with 20 animals per pond. The animals were submitted to biometrics and chip. The results were compared with respect to time factors and water treatments. The growth of cultivated fish was satisfactory in terms of mass and size gains in both periods evaluated. The dry season stood out as the one with the greatest increase in weight and size. Aquaponic systems proved to be viable in terms of the possibility of water treatment for the production of Nile tilapia, which can be used in areas with water shortages.
