Anoxic sediments favor sulfate reducing bacteria proliferation, main characteristic of reduced environments, which are used for crustaceous culture. In Mexico, it has been reported the presence of anoxic sediments in the channels of Xochimilco, reduced environment that could be used for culture of organisms, like crayfi sh (Cambarellus montezumae). The aim of this study was to prove that reduced environments can be used for the production of culture susceptible aquatic organisms for human consumption. Apatlaco and Cuemanco channels are characterized as reduced environments, its water and sediment physicochemical parameters were evaluated; heavy metals in sediment and organisms were assessed; presence and sanitary quality of crayfi sh was proven, through qualitative and quantitative analysis of its bacteria charge; nutritional quality of crayfi sh was determined, by proximal chemical analysis. It was proven that the channels of Xochimilco fulfi ll the reduced environment characteristics, presence of crayfi sh C. montezumae in these channels was verifi ed, it was shown that the levels of heavy metals and bacteria charge recorded, do not exceed the maximum allowed limits for edible crustaceous, important protein source for human consumption. Based on the previous, it is affi rmed that reduced environments can be used for culture of edible aquatic species. |
