The aquaculture is being characterized as strategy to minimize the reduction of the fish. At Pará, the oyster farming was implanted in 2003 as an opportunity regarding to occupation and profits generation at Northeastern of this state. In 2005 this initiative was expanded to other communities with different levels of familiarity with the mollusk, regarding to the support either on the researches in this sector or on the extractive activity. This research evaluated the communitarian oyster farming performance in the state of Pará. It was studied three projects with at least two years of implementation and with either different levels of preservation and oyster harvest activity. The implementation of the firsts cultivations occurred simultaneously and in a similar way regarding to institutional support, however with different performances. The main producer issues are to obtain the license to develop this activity and also the necessity to take care about the tide. It is necessary to provide more detailed feasibility studies, with more commitment from the side of the interested institutions in order to perform the actions they are supposed to work out, providing events where it will be possible to spread the information and discuss the aquaculture bottlenecks at the state of Pará, as well to provide a consolidated partners network to prepare the groups regarding to organization, activity management and helping in the market access. The most part of the oyster famers are small producers, artisanal fishermen that found a way to manage their families via oyster farming. However, the oyster farming is a secondary activity to them, once it is still not enough to support their necessities. Nevertheless, several farmers already declared once they manage how to increase the oyster production they will be exclusively dedicated to this activity.

Avaliação sanitária de água de cultivo e de ostras da zona do salgado, nordeste do Estado do Pará - Brasil
(Universidade Federal do Pará, 2011-04-19) KIYATAKE, Daniela Mayumi; RIBEIRO, Karla Tereza Silva; http://lattes.cnpq.br/2654817572738748; PAIVA, Rosildo Santos; http://lattes.cnpq.br/0510818763187669
The cultivation of oyster species of the genus Crassostrea is expanding in the northeast of the Brazilian state of Pará. This study analyzes the sanitary quality of the oysters and the water in which they are cultivated in the local municipality of São Caetano de Odivelas and Curuçá. Samples were collected monthly between June, 2009, and May, 2010. Water samples were collected from the flood and the ebb tides, and approximately 15 oysters were obtained each month. Coliform concentrations were determined using the multiple-tube fermentation technique, followed by the biochemical identification of the bacteria and determination the susceptibility profile of Escherichia coli isolated from oysters and water samples. The geometric mean concentration of thermotolerant coliforms in the water was 119 MPN/100 mL in São Caetano de Odivelas and 163,21 MPN/100 mL in Curuçá, well above the limit of 43 MPN/100 mL established by the Brazilian National Environment Council (CONAMA). As Brazilian legislation on the sanitary quality of bivalve mollusks covers only the processed product, the European Union legislation, which assigns oysters for raw consumption to three sanitary classes, was adopted for the evaluation of the results of the present study. In São Caetano de Odivelas only two of the samples collected during this study were assigned to class A, seven samples to class B and three samples to class C. While in Curuçá three samples were assigned to class A, seven samples to class C and two samples to class C. The results suggest the need for mitigation measures to ensure the health quality of the oysters, such as the application of methods of depuration.
