dc.description.abstractNote: See the PDF Version Sri Lanka is surrounded by a coastline of approximately 1700 Km, and belongs to an Exclusive Economic Zone (EEZ) of 517,000 Sq Km. About 50,000 people in the country are directly involved in the fishery industry. The total marine fish production in 2010 was recorded about 332,260 Metric tons (Mt), while Tuna contributed 88903 Mt to the total (Fisheries year Book, 2010). From the total yield about one-third of the catch of fish is not used for direct human consumption but for the production of fishery by products (Balios, 2003). Every year thousands of tons of fish by-products of high nutrient content are discarded by fish processing plants through the world although they can be utilized for other purposes. Crude tuna oil is produced from tuna waste by steam followed by purification, wet rendering, alkali digestion, acid silage Soxhlet like methods (Bimbo, 1990).Tuna fish oil has been considered as an available source of long chain polyunsaturated Omega 3 and Omega 6 fatty acids, especially eicosapentaenoic acid (EPA) and Docosa Hexaenoic Acid (DHA). Tuna oil differs from other fish oils in the ratio of the C20:5 n-3 (EPA) to the C22:6 n-3 (DHA) fatty acids. It means that the ratio of EPA: DHA in tuna oil around 1:4 is similar to that of human breast mil . This study attempted to find out the feasibility of producing Tuna fish oil using fish waste.en_US
