Fish farming in small floating cages is the subject of local\uddiscussions due to the possible sustainable use of the\udAmazon basin, alleviating poverty of people who live near\udlakes and rivers. “Tambaqui” is one of the main species\udindicated to this end because this is an omnivorous\udspecies, well accepted in the local market, whose demand\udgrows fast due to the over-fishing around big western\udAmazon cities such as Manaus. However, more\udinformation about “tambaqui” farming in small volume\udcages is necessary to increase and advance production in\udthis system. Therefore, we studied the effects of four\udstocking densities (10, 20, 30 and 40fish/m3) in “tambaqui” farming in small cages (1m3). We evaluated fish growth and number of gills parasites. The results showed clear fish biomass rise by the increase of “tambaqui” stocking density. No effect of stocking density\udwas observed on fish individual growth, survival and\udnumber of gills parasites
