In this context the objective of this work was to investigate the perception of the shrimp exporting entrepreneurs of Rio Grande do Norte, with relation to the impact of the Brazilian environmental legislation in the companies competitiveness at the external market. From data collected from the controllers of the companies, it was used a survey methodology, with exploratory and descriptive character. The results found in this study indicate that the companies, in general way, understand that the environmental legal requirements do not confuse nor help in the search and conquest of new international markets. A little more of the half of the researched companies, does not see the legislation rigid as important factor of competitiveness. However a sufficiently significant percentage, already has a more strategical vision on the subject, or at least already it heard to speak on such possibility / As exporta??es brasileiras v?m crescendo de forma constante nos ?ltimos anos, incentivadas pela globaliza??o e por pol?ticas p?blicas voltadas para o aumento do super?vit interno. Neste contexto o objetivo deste trabalho foi investigar a percep??o dos empres?rios exportadores de camar?o do Rio Grande do Norte com rela??o ao impacto da legisla??o ambiental brasileira na competitividade das empresas no mercado externo. A partir de dados coletados junto aos dirigentes das empresas, utilizou-se a metodologia de pesquisa do tipo Survey , de car?ter explorat?rio e descritivo. Os resultados encontrados neste estudo indicam que as empresas, de forma geral, entendem que as exig?ncias legais ambientais n?o atrapalham nem ajudam na busca e conquista de novos mercados internacionais. Um pouco mais da metade, das empresas pesquisadas, n?o v? a legisla??o r?gida como fator importante de competitividade. Por?m um percentual bastante significativo, j? t?m uma vis?o mais estrat?gica sobre o assunto, ou pelo menos j? ouviu falar sobre tal possibilidade

To be able to satisfy current society’s needs without compromising future generations to satisfy their needs, is the key to sustainability. Many old practices and methods have had negative impact on the environment, including food production & cultivation activities with aquaculture being one of them. A growing population and environmental pollution, demand new technologies to be developed, to ensure food supply but also not to harm the environment at the same time. Such technologies have been developed the last decades allowing for indoor farming of aquaculture species including shrimp. Shrimps are popular all over the world and their demand is continuously increasing. This thesis focuses on two different technologies that primarily aim to grow shrimps in the most effective way with reduced demand of natural and chemical resources considering sustainability. One technology is Biofloc, and the other is the Recirculated Aquaculture System (RAS). A multicriteria Decision Analysis (MCDA) will take place in this thesis to compare the two alternative technologies based on a few criteria. The criteria used, derive from two categories, operational and environmental, and this thesis aims to understand the pros and cons of each technology with respect to sustainability.

Using a bioeconomic model and stochastic simulation to assess the economic viability of small-scale, recirculating shrimp farms in the Midwestern U.S. A series of stress tests were implemented on key input variables including survival rate, selling price, electricity usage, discount rate and the cost of added salt. The key output variable is the Net Present Value of the operation. <div><br></div><div><br></div>
