摘要 [目的]比较大宁河野生齐口裂腹鱼和云南盘鮈的肌肉常规营养成分。[方法]对齐口裂腹鱼和云南盘鮈的肌肉常规营养成分进行了测定,并初步探讨了2种鱼的肌肉品质。[结果] 齐口裂腹鱼肌肉中粗蛋白、粗脂肪、水分和粗灰分含量分别为18.40%、0.60%、78.76%和1.24%,云南盘鮈肌肉中粗蛋白、粗脂肪、水分和粗灰分含量分别为20.23%、1.32%、76.49%和1.29%;2种土著鱼肌肉粗蛋白含量均高于部分常规鱼类,在所属同亚科鱼类中也处于较高水平。[结论]2种土著鱼均为高蛋白、低脂肪的优质鱼类,但云南盘鮈的营养价值稍优于齐口裂腹鱼。

Abstract [Objective] The research aimed to compare the conventional nutrients in muscle of Schizothorax prenanti and Discogobio yunnanensis from Daning River. [Method] The conventional nutrients in the muscle of S. prenanti and D. yunnanensis were determined and the results were analyzed, while, the muscle quality was discussed preliminary. [Results] The contents of crude protein, crude fat, moisture and crude ash in the muscle of S. prenanti were 18.40%, 0.60%, 78.76% and 1.24%, the contents of crude protein, crude fat, moisture and crude ash in the muscle of D. yunnanensis were 20.23%, 1.32%, 76.49% and 1.29%; Compared with conventional fish and subfamily fish, the contents of crude protein in the muscle of two kinds of native fish were at a higher level. [Conclusion]S. prenanti and D. yunnanensis were high-quality fish species with high protein and low fat, relatively speaking, the nutritional value in muscle of D. yunnanensis was slightly better than S. prenanti.

大寧河是长江中上游的一级支流,古称昌江,又名巫溪水,发源于大巴山南麓巫溪县,由北向南主要流经巫溪县和巫山县,在巫峡西口注入长江,巫溪庙溪以上河段水质达Ⅰ类水质标准。齐口裂腹鱼(Schizothorax prenanti)和云南盘鮈(Discogobio yunnanensis)是大宁河中上游的主要渔获物和重要土著经济鱼类之一,均属于冷水性鱼类,具有耐低温和味道鲜美等优点,是颇具发展前景的优良野生鱼类品种。目前,有关青衣江、四川黑水和雅安等地区所产齐口裂腹鱼的肌肉营养已有一些报道[1-3]。但是,迄今为止有关大宁河齐口裂腹鱼和云南盘鮈的肌肉营养还未见报道。2种鱼食性相近,摄食方式相同,笔者对其常规营养成分进行比较,初步对比并评价其肉质差异,旨在充实鱼类营养学,并为其人工养殖提供参考。……
