This study aimed to determine the chemical composition, the profile fatty acids and caloric value of three species of crustaceans of the State of Ceará. The species are the most commercialized, spiny lobster (Panulirus argus), white shrimp (Litopenaeus vannamei), crab uçá (Ucides cordatus). The results showed high levels of moisture in Crab viscera. The meat of lobster and crab presented higher percentages of protein. The levels of total lipids were higher in lagosta.Quanto hepatopancreas of the ash, the highest values ​​were detected the head of shrimp and crab meat. The caloric value was greater found in the hepatopancreas of lobster. In meat and lobster hepatopancreas highlights are the fatty acids: palmitic, stearic, oleic. In the fraction of lipids neutral shrimp head, the four major fatty acids were linoleic, palmitic, oleic and DHA. Phospholipids in this sample, the fatty palmitic, linoleic, oleic and stearic acids were the major ones.
