Perspectives for the development of marine shrimp farming in the estuary of Patos Lagoon, RS, Brazil

Shrimp production in Brazil has presented a significant increase in the last few years, especially in the northeastern region. Although climatic conditions in southern Brazil do not allow year-round production, considerable investments have been made in the region. In the estuarine area of Patos Lagoon, the culture of the native Farfantepenaeus paulensis in cages and pen enclosures, and of Litopenaeus vannamei in earthen ponds are being developed as new activities that will certainly produce social and economical development to the region. Nevertheless, the implantation of shrimp farming without proper ordination and control may generate serious environmental problems. The present paper presents an overview of the environmental characteristics of the area and describes the farming systems currently adopted. Furthermore, the main challenges faced by this new activity, such as the discussion of a legislation adapted to local conditions, and the definition of areas appropriate for farming are presented. Finally, the sustainable development of shrimp farming is discussed under social, economical and environmental perspectives.
