Viabilidade da aquaponia urbana: pequenos espaços e a produção animal sustentável

Abstract

The present work is a qualitative extension of the studies begun in ESO (Mandatory Supervised Internship). The installation of another aquaponics system in a building located in Sossego street, located in the Boa Vista neighborhood, central region of Recife, where the Cultural Center Brazilian Germany (CCBA) operates, has enabled us to carry out a comparative analysis with systems that were (UFRPE) campus, as well as another system set up at the Professor Johei Koike (UFRPE) Aquaculture Station / Department of Fisheries and Aquaculture (DEPAQ), also on the campus of the Aquaculture and Sustainability Laboratory of the Department of Animal Science of the Federal Rural University of Pernambuco headquarters of (UFRPE). Some observation points followed the following variables and requirements such as: system assembly; necessary materials; water conditions (pH, temperature, dissolved oxygen, carbonate hardness, toxic ammonia, nitrite); conditions of light incidence; productivity; monitoring of the system in fish farming and plant cultivation; management of the aquaponic system, yield of final production (animal and plant biomass), emergence of pests and diseases for animals and plants, evaluate responses of both to the conditions found in each parameter, besides costs for such an undertaking. However, to make a general survey of all the data inherent to the project and to evaluate the viability of this project, it should be used in small spaces, with little supply or availability of natural resources, deficiency in organic food production and work. The work also has the purpose of generating technical knowledge that can be applied in society, especially in family agriculture, with small and medium-sized rural producers and in urban centers, constituting a possible source of organic food, besides the possibility to be an alternative income generation for many families inserted in rural areas, thus avoiding the increase of the rural exodus and the most important, helping to solve the great problem of hunger in the world, especially in the most needy regions such as the Brazilian Northeast. This experimental research was carried out under the cultivation methodology of the Nutrient Film Techinique (NFT), and until the last test performed, the above-mentioned parameters as system variables, were zeroed to those that are systemic such as toxic ammonia and nitrites, as expected, showing the efficiency of systems in symbiotic processes.
