Comparison on Nutrient Composition and Amino Acid and Fatty Acid Profile of Muscle in Wild and Farmed Carassius auratus

Abstract:

The nutritional compositions, including amino acids and fatty acids profile in muscle were compared between wild and farmed Carassius auratus to evaluate the nutritional value. The contents of moisture, crude protein, fat, carbohydrate and ash in wild C. auratus were 74.47%, 19.12%, 3.72%, 1.52% and 1.18％, and those of farmed C. auratus were 74.03%, 18.41%, 4.54%, 1.95% and 1.06％, respectively. The contents of total amino acids (TAA) and essential amino acids (EAA) in wild C. auratus were obviously higher than those of farmed group (dry sample), whereas the protein of farmed C. auratus has more well-balanced amino acid composition based on the Amino acid scores. Abundant polyunsaturated fatty acids (PUFAs) were observed in the muscles of two groups, however the ratio of n-6/n-3 especially the wild group were significantly higher than the value (4.0 at maximum) recommended by UK Department of Health and the value of China (4:1～6:1). So the fatty acids composition of C. auratus was not ideal for the human health.
