Comparison of nutrient components in muscle of wild and farmed groups of Myxocyprinus asiaticus

The nutrient components in muscles of wild and farmed groups of Myxocyprinus asiaticus were compared.The results showed that the moisture,crude protein and crude ash contents in the muscle of the wild M.asiaticus were significantly higher than that of the farmed M.asiaticus(P0.05),while the flesh content and crude fat content in the muscle of wild M.asiaticus were significantly lower than that of farmed M.asiaticus(P0.05).The amino compositions of the two groups are in substantial agreement,including 17 kinds of amino acids(tryptophan was not measured).The essential amino acids index(EAAI) in the muscle of wild and farmed M.asiaticus was 70.39 and 67.02,respectively.According to AAS,the first limited amino acid is Val,while the CS standard was(Met+Cys).The percentage of SFA,MUFA and PUFA in the fatty acids of between the wild and the farmed stocks were 44.23%,31.07%;32.07%,49.50%;23.65%,23.11% respectively.It was clear that the amount of SFA in the muscle of wild M.asiaticus was significantly higher than that of the farmed M.asiaticus(P0.05).While the amount of MUFA in the muscle of wild M.asiaticus was significantly lower than that of the farmed M.asiaticus(P0.05).The amount of PUFA in the muscle of wild M.asiaticus showed no significant difference than that of the farmed M.asiaticus(P0.05).
