Resumo: | The objective of this work was to identify and quantify the flow of greenhouse gases (CH4, CO2, N2O) in Litopenaeus vannamei shrimp nurseries submitted to different culture conditions. The experiment was developed with a completely randomized design, with two treatments and four replicates simultaneously, making a total of eight experimental units. Two management systems were tested: the first one (M1) used stocking density of 92 shrimp/m², maintenance fertilization with the application of calcium nitrate and molasses, and feeding through the exclusive feed method in trays for the supply of feed . The second one (M2) used a density of 14 shrimps/m², but using maintenance fertilizations constituted only by the application of calcium nitrate, the feeding consisted of the feed offered through the volley method. The results showed that there were variations in the emission standard for the two treatments used, as well as in the concentrations of the evaluated gases. The mean values of total gas flow recorded were -314,87 mg.m².dia-1 de CH4, -3773,51 mg.m².dia-1 de CO2, 2,47 mg.m².dia-1 de N2O for M1. However, for M2, the following values were: 653,89 mg.m².dia-1 de CH4, 497,52 mg.m².dia-1 de CO2, 25,59 mg.m².dia-1 de N2O. Thus, the results obtained in this study suggest that the multiple environmental and management conditions offered in the crop interfere with the production and emission of the gases, and can act as a source or sink for these gases. In this context, it can be concluded that shrimp farming, when combined with the use of adequate operational management, with better feed utilization and adequate fertilization, has the potential to absorb some gases such as CH4 and CO2, And lower emission of N2O even using high crop densities, opposing the paradigm that the greatest environmental damage caused by shrimp farming occurs through intensive cultivation |

O experimento foi desenvolvido com um delineamento inteiramente casualizados, com dois tratamentos e quatro repetições simultaneamente, perfazendo um total de oito unidades experimentais. Foram testados dois sistemas de manejo: o primeiro (M1) utilizou densidade de estocagem de 92 camarões/m², fertilizações de manutenção com a aplicação de nitrato de cálcio e melaço, e arraçoamento através do método de alimentação exclusiva em bandejas para a oferta de ração. Já o segundo (M2) utilizou uma densidade de 14 camarões/m², porém utilizando fertilizações de manutenção constituídas apenas pela aplicação do nitrato de cálcio, o arraçoamento consistiu na ofertada de ração através do método de voleio. Os resultados mostraram que houve variações nos padrão de emissões para os dois tratamentos utilizados, bem como nas concentrações dos gases avaliados. Os valores médios de fluxo total de gases registrados foram -314,87 mg.m².dia-1 de CH4, -3773,51 mg.m².dia-1 de CO2, 2,47 mg.m².dia-1 de N2O para o M1. Enquanto para M2 os valores foram os seguintes: 653,89 mg.m².dia-1 de CH4, 497,52 mg.m².dia-1 de CO2, 25,59 mg.m².dia-1 de N2O. Assim, os resultados obtidos nesse estudo sugerem que as múltiplas condições ambientais e de manejo oferecidas no cultivo interferem na produção e na emissão dos gases, podendo atuar como fonte ou sumidouro desses gases. Neste contexto, pode-se concluir, pelo presente estudo, que a carcinicultura quando combinada com a utilização de um manejo operacional adequado, com melhor aproveitamento de ração e uso adequado das fertilizações, apresentou potencial para absorção de alguns gases, como CH4 e CO2, e menor emissão de N2O mesmo utilizando altas densidades de cultivo, opondo-se ao paradigma de que os maiores danos ambientais causados pela carcinicultura ocorrem pelo cultivo intensivoCoordenação de Aperfeiçoamento de Pessoal de Nível Superior2017-06-29application/pdfhttp://repositorio.ufersa.edu.br/retrieve/1858/DanyelaCES_DISSERT.pdf.jpgporUniversidade Federal Rural do Semi-ÁridoPrograma de Pós-Graduação em Ciência AnimalUFERSABrasilCC-BY-SAinfo:eu-repo/semantics/openAccessAquecimento globalEmissões animaisGases do efeito estufaCarciniculturaImpactos ambientaisGlobal warmingAnimals emissionsGreenhouse gasesShrimp farmingEnvironmental impactsCNPQ::CIENCIAS AGRARIAS::MEDICINA VETERINARIAEmissão e absorção de gases do efeito estufa decorrentes da produção de camarão marinho (Litopeneaus vannamei)Emission and absorption of greenhouse gases from the production of marine shrimp farm (Litopeneaus vannamei)info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisreponame:Biblioteca Digital de Teses e Dissertações da UFERSAinstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAORIGINALDanyelaCES_DISSERT.pdfDanyelaCES_DISSERT.pdfapplication/pdf1713909https://repositorio.ufersa.edu.br//bitstream/tede/736/1/DanyelaCES_DISSERT.pdfccb0c824d68de4c25cae5e27a6c430afMD51LICENSElicense.txtlicense.txttext/plain;
