Tuna, known as the ‘Chicken of Sea’ have red and white flesh in their bodies which taste differently. Red and White meat of Little Tunny (Euthynnus affinis) and Skipjack Tuna (Katsuwonus pelamis), widely available cheap tuna species in the food market were subjected to biochemical analysis to estimate the food value. K.pelamis have more nutritive value than E.affinis, but both species can provide satisfactory amount of nutrients in diet including a reasonable amount of omega-3 fatty acids. Red meat was found out to be equally nutritious as white meat. Red and white meat of both K.pelamis and E.affinis can be recommended in diet as excellent nutrient source.
