Description The polyunsaturated fatty acids (PUFAs), mainly eicosapentaenoic acid (EPA) and
docosahexaenoic acid (DHA), help keeping the blood cholesterol level low and thus preventing
coronary heart disease. These fatty acids play an important role in reducing the risk of colon,
breast and prostate cancer. Although, carps form the major chunk of harvested fish worldwide,
the information about their fatty acid profiles is meager. The present study was, therefore
conducted to know the muscle total lipid content (MTLC) and fatty acid profiles of six carp
species, Labeo rohita (Ham.), Catla catla (Ham.), Cirrhinus mrigala (Ham.), Cyprinus carpio
(Linn.), Ctenopharyngodon idella (Steindachner) and Hypophthalmichthys molitrix (Richardson).
The MTLC varied within the species of fish (0.99±0.02% in C. idella to 3.03±0.05% in C.
carpio) and season of the year. The minima were recorded during spring except in C. mrigala
(summer), and maxima during winter except C. carpio (summer) and C. idella (autumn). The
highest EPA+DHA content (g/100g of muscle) was obtained from C. idella (0.56) in spring, C.
mrigala (0.27) in summer, C. carpio (0.33) in autumn and L. rohita (0.22) in winter. Based on the
availability of EPA+DHA, and the cost of obtaining 1g of these fatty acids, C. idella and H.
molitrix were the cheapest source of EPA+DHA (Rs. 35.5 and 59.3, respectively) in spring. In
summer, C. mrigala was the cheapest source (Rs. 90.9), While in autumn these were C. carpio
and C. catla (Rs.61 and 68, respectively). In winter, L. rohita and H. molitrix were the cheapest
(Rs. 81.3 and 85.1, respectively
