【摘要】 对同一海区不同养殖模式(大围网、传统网箱)的成年大黄鱼及野生成年大黄鱼进行体色、背部肌肉肉质性状(pH值、常规营养成分、氨基酸、脂肪酸)的测定及肌肉感官性状的主观评定。结果表明:大围网养殖大黄鱼的体色与野生大黄鱼接近(P>0.05),显著优于传统网箱养殖大黄鱼(P<0.05)。大围网养殖大黄鱼肌肉的粗蛋白、氨基酸总量、呈味氨基酸总量、鲜味氨基酸总量及多不饱和脂肪酸(PUFA)总量均显著高于传统网箱养殖大黄鱼(P<0.05);肌肉的粗脂肪、饱和脂肪酸(SFA)总量及单不饱和脂肪酸(MUFA)总量均显著低于传统网箱养殖大黄鱼(P<0.05);肌肉的pH值、水分和粗灰分差异不显著(P>0.05)。大围网养殖大黄鱼肌肉的感官性状显著好于传统网箱养殖大黄鱼(P<0.05)。大围网养殖大黄鱼上述肉质性状接近野生大黄鱼(P>0.05)。大围网养殖可改善大黄鱼的生活环境,补充天然饵料,是一种提高大黄鱼肉质的可行途径。更多还原

【Abstract】 Skin color,back muscle meat quality(i.e.,pH,nutritional composition,amino acids and fatty acids) and sensory evaluation of adult Pseudosciaena crocea harvested from the aquacultural(i.e.,enclosing and traditional caging) and open sea in the same area were determined.The results showed that the skin color and sensory quality of the P.crocea from enclosing aquaculture was similar to the wild(P<0.05) but superior to that from the traditional caging method(P<0.05).Comparing the P.crocea harvested from the enclosing and caging aquaculture,the former contained significantly higher(P<0.05) amounts of crude protein,amino acids,polypeptides and polyunsaturated fatty acids,and significantly lower(P<0.05) amounts of crude fat,saturated fatty acids and monounsaturated fatty acids than the latter.There were no significant differences(P>0.05) in pH,moisture and ash contents between the 2 aquaculture products.The quality and chemical make-up of the P.crocea from the enclosing aquaculture were close to those in the wild(P>0.05).更多还原
