Seasonal variation in the proximate composition(moisture, protein, fat, carbohydrate and ash) wasanalysed in emperor fish (Lethrinus lentjan). Mineralcomposition (iron, phosphorus, sodium, potassiumand calcium) was also analysed. Moisture, protein,fat, carbohydrate and ash contents were found torange 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 acidprofile of emperor fish revealed palmitic acid (C16),stearic acid (C18) and myristic acid (C14) to be themajor saturated fatty acid and elaidic acid (C18:1n9T)and oleic acid (C18: 1n9C) were the dominantmonounsaturated fatty acids. Investigations alsorevealed that fat content was higher during themonsoon season (October and November).
