| 摘 要： | 红树林因其独特的生长环境,具有重要的生态、经济和社会意义。中华乌塘鳢(Bostrychus sinensis)是我国优良的养殖品种。为提高红树林的生态与经济效益,对红树林下中华乌塘鳢铁笼养殖技术进行研究探讨,并分析比较红树林下养殖鱼、光滩笼养鱼与野生鱼肌肉的营养成分。结果显示:以上各组鱼体的粗蛋白含量均较高(74.65%~83.08%),粗脂肪含量较低(0.89%~1.63%),其中红树林下养殖鱼的粗蛋白和粗脂肪含量分别高于光滩养殖鱼;各组实验鱼的氨基酸总量(71.72%~79.27%)、鲜味氨基酸总量(29.03%~30.92%)、必需氨基酸总量(27.47%~31.57%)、非必需氨基酸总量(44.25%~47.69%)均以野生鱼为最高,光滩投饵组最低,红树林下养殖组高于光滩养殖组;各组实验鱼肌肉必需氨基酸指数EAAI均较高(66.83~74.90),限制性氨基酸为缬氨酸、异亮氨酸和(蛋+胱)氨酸,支链氨基酸总量/芳香族氨基酸总量(F值)为2.17~2.22;红树林下养殖鱼肌肉中的n-3系列多不饱和脂肪酸含量和(EPA+DHA)含量均分别高于光滩养殖鱼,红树林下养殖的中华乌塘鳢肌肉脂肪酸组成比光滩养殖鱼具有更高的营养价值。

| Abstract: | This study was conduct to analyze and evaluate the muscle nutritive compositions of cage-culture Bostrychus sinensis in mangroves area,and compared with those of wild,pond-culture and mudflat-cultured fishes.The results showed that the muscle of B.sinensis in all groups contain high protein but low lipid.The muscle protein and lipid contents of B.sinensis cultured in mangroves area were higher than that cultured in mudflat.The total amount of amino acids (71.72%~79.27%),delicious amino acids (29.03%~30.92%),essential amino acids (27.47%~31.57%) and non-essential amino acids (44.25%~47.69%) of fish muscle were the highest in wild fish and the lowest in mudflat-cultured fish,respectively,but fishes cultured in mangroves area were higher than those cultured in mudflat.The essential amino acid index (EAAI) of fish muscle in all groups were higher (66.83~74.90).The limiting amino acids were valine,isoleucine and (methionine+cystine).Total branched-chain amino acid/total aromatic amino acid (F value) were also high in all groups (2.17~2.22).The n-3 polyunsaturated fatty acids and high unsaturated fatty acids (EPA+DHA) of fishes cultured in mangroves area were higher than that of cultured in mudflat.In conclusion,the muscle nutritive value of B.sinensis was very high and the meat quality was better.Moreover,fishes cultured in mangroves area showed superior nutritive compositions to those of cultured in mudflat. |
