Abstract

Sardinella longiceps were studied for the spatial (south west (SW) and southeast (SE) coast of India), annual (2008, 2009, 2010 and 2011) and seasonal (pre-monsoon, monsoon and post-monsoon) variations of protein, amino acids, minerals and vitamins. The chlorophyll-a concentration and sea surface temperature of its habitats were taken into account to understand their effect on the nutrient signatures of oil sardine throughout the study period and locations. Mean protein content attained its maximum during pre-monsoon along both SW and SE coasts, with high proportions of essential amino acids. Essential to non-essential amino acid ratio, total aromatic (TArAA) and total sulfated amino acids (TSAA) recorded monsoon maxima along the study locations. Amino acid scores observed monsoon and post-monsoon maxima along the SW and SE coast, respectively. Minerals were significantly higher during monsoon along the SE coast (P<0.05). Significant seasonal variations in vitamin content were observed along the study locations with high vitamin A, D3 and C on SW coast and higher vitamin E and K in SE coast. The present study demonstrated Sardinella longiceps as a valuable source of the protein, amino acids, minerals and vitamins. A reasonably good ratio of essential to nonessential amino acids for oil sardines was recorded throughout different study period and locations, and therefore it can be concluded that this low-value species is an excellent source of good balanced proteins with high-biological value to be qualified as a preferred health food for human diet.
