7. Sistemas de cultivo integrados baseados no conceito de emissão zero em micro-escala
A great predatory pressure on the reduced number of fishing option has produced difficulty to the market to cover the demand of fishing products. This fact justifies itself by the domain of the linear products that envolve the unilateral technologies of the exploitation of the resources, this limits the possibility of choice of the product. The final objecti
