Proximate composition of sharks, skates and rays varies in the different seasons of year and from specimen to specimen and even in the same specimen from part to part of the body. Lipid is the most variable component, from 0.4 to 6.2% in the body and from 12.5 to 48.4% in the liver in fresh condition. Moisture content is found varying between 71.0 and 84.0%. There is an inverse relationship between the quantum of water and lipid in the tissue. Protein content is found to increase with age. Carbohydrate and mineral contents were estimated and discussed in detail.
