ABSTRACT
Nowadays, the consumption of fish, as food has been increasing as fish contains almost all major and minor nutrients and show positive health benefits. Sensory attributes like texture, taste, flavor, appearance, and quality are the main concern for the consumers which are due to the net result of 320complex reactions between major and minor nutrients. The geographical location, morphology, season, ecosystem, culture practices are the different components that play a significant role play in representing the quantity of these nutrients. When compared with amino acid (AA) composition, fatty acid composition is mostly affected by food. In one way or other, all the coldwater fishes are good in their nutrient composition. Most of the important cold water food fishes are superior in expressing the ratio of n–6/n–3 fatty acids. All the amino and fatty acid composition in coldwater fishes show good effect on the cardiovascular system of adults and prenatal development in the case of children. The present chapter is aimed to compile and complement to the available nutritional composition of coldwater fishes in view of proximate, fatty acid and AA phrases along with medicinal benefits.
