This experiment was carried out to compare the difference of lipid components, amino acid composition by size of sea eel. Large sea eel(length 57.5-60.0cm, weight 269.5-300.0g) was higher in moisture and crude protein content, and lower in crude lipid content than those of small sea eel(28.8-31.2cm,...

This experiment was carried out to compare the difference of lipid components, amino acid composition by size of sea eel. Large sea eel(length 57.5-60.0cm, weight 269.5-300.0g) was higher in moisture and crude protein content, and lower in crude lipid content than those of small sea eel(28.8-31.2cm, 39.5-43.6g). Total lipid(TL) of large and small sea eel were consisted of 89.7%, 93.3% neutral lipid, 8.9%, 5.2% phospholipid, and 1.4%, 1.5% glycolipid, respectively. In fatty acid composition of TL, large fishes revealed higher content in polyunsaturated fatty acids such as 20:5, 22:5, 22:6, while lower in saturates and monoenes such as 16:0, 16:1, 18:1 than those of small fishes. The major fatty acids of these fishes were generally 18:1, 16:0, 22:6, 16:1 and 20:5 in order. Total amino acid contents of large and small sea eel were 17022.7mg/100g, 15409.4mg/100g. And the main amino acids were aspartic acid, glutamic acid, isoleucine, leucine, lysine, arginine. Large fishes was higher in cystine, methionine, tyrosine, phenylalanine content, while lower in aspartic acid, glutamic acid than those of small ones.
