Tamuatá shells (Hoplosternum littorale) were analyzed chemically, in order to determine the percentual values of total nitrogen (N), calcium ion (Ca+2), total phosphorus (P), magnesium ion (Mg+2) and potassium ion (K+1). The shells from the processing of the meat of the fish, were washed, brushed and placed to drying in greenhouse at 60oC for 72 hours until the weight becomes constant. The material, after drying, was finely ground for further analysis, the results were 4.7% of total N, 14.1% Ca+2, 2.22% total P, 0.25 Mg+2 and 0.5% K+1.
