Item Viabilidade da aquaponia urbana: pequenos espaços e a produção animal sustentável(2019-06-19) Machado, Eric; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086The 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.Item Prospecção ambiental em áreas rurais: o estudo de caso da zootecnia em Paulista - PE(2019-01-15) Oliveira, Marina Ximenes de Lima; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086; http://lattes.cnpq.br/9673126144809309Agricultural activities are causing environmental impacts and all of those activities generate liquid effluents, which when improperly disposed can cause soil, air and water pollution. In addition, the use of natural resources in a irresponsibly way also causes negative results to the environment. The objective of this study was to determine through one case study, the main environmental impacts and their variables due the zootechnical activities developed in the stretch area located on the banks of the Paratibe River, municipality of Paulista (Pernambuco state) during the months of June, July and August of 2018, using the following methodologies: field check list to characterize the environmental diagnosis; hydrological analysis of the Paratibe river in the aforementioned station for pH measurement, transparency, nutrient concentration; and samples for plankton community analysis to perform the occurrence stimation of each organism identified that is in this work function as bioindicators. Data from the planktonic community were submitted to statistical analysis using the Relative Abundance (RA) and Frequency of occurrence (OF) methods. The impacts evidenced in the area during the months of June, July and August/2018 were quantified respectively with the following total indices: -173, -178, -232 which prove the presence of extreme environmental impacts. The nutrient contents were 2.8 mg/L for nitrite concentration and 39.95 mg/L nitrate, mean concentrations of ammonia in the Paratibe river were 3.995 mg/L and for water transparency measurements were verified values of 30 and 40 cm depth of penetration of sunlight. In the three collected samples of plankton 5 taxa were identified in total (Protozoa, Rotifera, Nematoda, Polychaeta, and Copepoda) plus Diptera larvae (insects). With respect to the Protozoa in this work they were visualized as external parasites of some Copepoda organisms, as well as filamentous bacteria. It was verified that the contents of all the analyzed nutrients exceed the maximum concentrations allowed by Resolution 357 ̸2005 of the National Council of the Environment (Brazilian CONAMA); also, that there is a little variety and less survival rates of plankton in the waters of the Paratibe river and that there is much contamination of solid waste in the studied environmental area. Therefore, the region needs preventive and emergencial measures that will guarantee the conservation of this ecosystem and will help in the development of a sustainable animal production breeding system, capable of providing sanitary security to the producer and the population.
