Resumo: | With a growing world population and increasing demand for quality food in sufficient quantities, the aquaculture fits in this context as a producer of high quality animal protein with high productivity. The fish production in ponds has practiced for over five decades in Rio Grande do Sul state. The fish culture system commonly used is the carp only polyculture, which consists in culturing different carp species aiming to improve the performance of each one and, therefore, achieve high productivity. The carp polyculture has a low technological level and the production obtained is considered small moreover, the release of effluents in natural water bodies may cause an imbalance in the natural aquatic environment. Some studies have been performed adding the silver catfish to the traditional polyculture. Also, several studies were performed about economic viability, but with a single species, or consortium, as is the case of polyculture of shrimp and Nile tilapia. We tested the polyculture with partial substitution of 25, 50 and 75% of carps by silver catfish and Nile tilapia. We analyzed the economic viability of all substitution rates by obtaining the Net Present Value (NPV), Annual Value (AV), Internal Rate of Return (IRR) and Pay Back period. In conditions of uncertainty, we held on sensitivity analysis and evaluation through the Monte Carlo method. We concluded that substitution rate of 25% of carps by silver catfish and Nile tilapia has higher biomass production and better effluent quality. Regarding economic analysis, an investment in polyculture with vita useful 25 years is economically feasible for a fee Minimum Attractiveness (TMA) of 6.17%. |

Com o crescimento da população mundial e o aumento da demanda por alimentos de qualidade e em quantidades suficientes, a aquicultura se encaixa neste contexto como atividade produtora de proteína animal de alta qualidade e em grande quantidade por área utilizada. A produção de peixes em tanques de cultivo já é praticada a mais de cinco décadas no Rio Grande do Sul, e o sistema comumente utilizado é o policultivo de carpas, que consiste na consorciação de diferentes espécies de carpas visando melhorar o rendimento de cada uma e consequentemente obter uma produtividade maior. Porém o policultivo de carpas atualmente utilizado possui baixo nível tecnológico, a produção obtida é considerada pequena e, além disso, ocorre a liberação de água eutrofizada nos corpos naturais d’água ocasionando um desequilíbrio no ambiente aquático natural. Estudos já foram realizados acrescentando o jundiá, ao policultivo tradicional, obtendo com isso bons resultados. Alguns estudos sobre viabilidade econômica foram efetuados, porém com espécies isoladas, ou consorciadas, como é o caso do policultivo de camarões e tilápias-do-nilo. Realizou-se a avaliação do projeto e o método de avaliação na condição de risco para o Método Monte Carlo. Concluiu-se que a substituição de 25% das carpas por jundiás e tilápias-do-nilo apresenta maior produção de biomassa, parâmetros de efluente com melhor qualidade, e que um investimento em policultivo com vida útil de 25 anos é viável economicamente para uma Taxa Mínima de Atratividade (TMA) de 6,17%.Associação Brasileira de Engenharia de Produção2014-11-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfvideo/mp4https://www.producaoonline.org.br/rpo/article/view/159010.14488/1676-1901.v14i4.1590Revista Produção Online; Vol. 14 No. 4 (2014); 1292-1315Revista Produção Online; v. 14 n. 4 (2014); 1292-13151676-1901reponame:Revista Produção Onlineinstname:Associação Brasileira de Engenharia de Produção (ABEPRO)instacron:ABEPROporhttps://www.producaoonline.org.br/rpo/article/view/1590/1216https://www.producaoonline.org.br/rpo/article/view/1590/1215Copyright (c) 2014 Revista Produção Onlineinfo:eu-repo/semantics/openAccessRitter, FilipePandolfo, AdalbertoBarcellos, Leonardo José GilRitter, Vanessa Rita dos SantosPandolfo, Luciana MarcondesTagliari, Leandro DóroBarbacovi, Naira Elizabete2015-11-11T17:25:32Zoai:ojs.emnuvens.com.br:article/1590Revistahttp://producaoonline.org.br/rpoPUBhttps://www.producaoonline.org.br/rpo/oai||producaoonline@gmail.com1676-19011676-1901opendoar:2015-11-11T17:25:32Revista Produção Online - Associação Brasileira de Engenharia de Produção (ABEPRO)false |
