In order to verify the centesimal composition, these animals caught in Sepetiba Bay （Rio de Janeiro, Brazil）, 20 samples of Ucides cordatus, Cardisoma guanhumi, Menippe nodifrons, Callinectes danae and C. exaperatus had their edible and waste parts （shells and hepatopancreas） analyzed in the Laboratory of Bromatology of the UFRRJ. The analysis revealed that the meat of crustaceans is protein （12.68% to 25.56%） and low in fat （0.37% to 0.67%）, sticking to a more demanding consumer market for thin products; the waste has already presented a protein content ranging from 15.75% to 27.64% and fat from 0.75% to 3.27%, with values of calcium （17.96% to 25.23%） and phosphorus （0.93% to 1.55%）, setting a precedent for use in animal feed through future studies in area.展开更多
