Description Inter-annual and seasonal variability in the nutritional parameters of the edible portion of skipjack tuna (Katsuwonus
pelamis) collected from the Arabian Sea were determined for a period of 4 years. Greater levels of long chain n-3 fatty
acids (35% during pre-monsoon), critical in the human diet for their anti-inflammatory properties with greater n-3:n-6
fatty acid ratio (8:12) demonstrated that this species may serve as an alternative to balance the greater amount of n-6
fatty acids. The present study demonstrated skipjack tuna as a significant source of protein, amino acids, minerals and vitamins.
A balanced essential to non-essential amino acid ratio (1.2:1.4) in the fillets indicated that this species could provide
well-balanced protein depositions. Vitamins A and K1 demonstrated post-monsoon maxima, whilst vitamins D3 and E
showed pre-monsoon maxima. Greater calcium (172 mg 100 g21
) and phosphorus contents (923 mg 100 g21
) were recorded
in the fillets of skipjack tuna during the pre-monsoon season. The chlorophyll-a concentration and sea surface temperature of
its habitat were considered to understand their effect on the nutritional composition of skipjack tuna all through the study
period. Significant correlation between long chain n-3 polyunsaturated fatty acids such as eicosapentaenoic acid and docosahexaenoic
acid (r
2 0.99) of skipjack tuna alongside chlorophyll-a concentration was observed, particularly during the
monsoon. The lesser atherogenic/thrombogenicity indices (,1), greater hypocholesterolaemic/hypercholesterolaemic ratio
(.1.0), and lesser cholesterol contents (,50 mg 100 g21
) of the fillets in skipjack tuna contributed towards its parameters
to be qualified as a high value, balanced nutritional source.
