    Seasonal variation in the proximate composition (moisture, protein, fat, carbohydrate and ash) was analysed in emperor fish (Lethrinus lentjan). Mineral composition (iron, phosphorus, sodium, potassium and calcium) was also analysed. Moisture, protein, fat, carbohydrate and ash contents were found to range from 74.93–78.20, 14.53–24.40, 0.21–2.76, 0.49– 1.07 and 1.24–2.70% respectively. Iron, phosphorus, sodium, calcium and potassium was 4.20, 13.50, 7.20, 156.20 and 17.90 mg% respectively. Fatty acid profile of emperor fish revealed palmitic acid (C16), stearic acid (C18) and myristic acid (C14) to be the major saturated fatty acid and elaidic acid (C18:1n9T) and oleic acid (C18: 1n9C) were the dominant monounsaturated fatty acids. Investigations also revealed that fat content was higher during the monsoon season (October and November).
