摘要
通过对异育银鲫(Ⅰ)Carassiusauratusgibelio♀×CyprinuscarpioL ♂、异育银鲫(Ⅱ)Caras siusauratusgibelio♀×Carassiusauratuscuvieri♂、生产所用的亲本鱼方正银鲫Carassiusauratusgibelio(Bloch)、鲤CyprinuscarpioL 和白鲫CarassiusauratuscuvieriTemmincketSchlegel共5种鱼的肌肉营养成分进行分析,结果表明:母本方正银鲫的肌肉蛋白质含量(180 3mg/g)和肌肉干物质中的氨基酸总量(714 277mg/g)、人体必需氨基酸含量(280 164mg/g)和呈味氨基酸含量(281 091mg/g)等指标均高于其后代和父本鲤、白鲫;雌核发育后代的肌肉营养成分介于双亲之间,低于母本方正银鲫而高于父本鲤和白鲫;以白鲫为父本的异育银鲫(Ⅱ)的肌肉营养成分要高于以鲤为父本的异育银鲫(Ⅰ);异育银鲫可利用雌核发育的生长生物学效应,但对肉质的改良没有作用。
The compositions were analyzed in muscles from 5 different fishes, Carassius auratus gibelio ♀×Cyprinus carpio L. ♂, allogynogenetic silver crucian carp Carassius auratus gibelio ♀×Carassius auratus cuvieri♂, Fangzheng crucian carp as one of the parent, Common carp Cyprinus carpio L.and Osaka crucian carp Carassius auratus cuvieri. The results showed that Fangzheng crucian carp as female had the highest concentrations of protein (180.3 mg/g), total amino acids(714.277 mg/g), essential amino acids (280.164 mg/g) and delicious amino acids (281.091 mg/g). For the allogynogenetic silver crucian carp, the values were mediate between the parents, lower than the male line of Fangzheng crucian carp, and higher than the female line of common carp or crucian carp.
