【摘要】 大鳞鲃(Barbus capito)属于鲤科、鲃亚科,鲃属,产于乌兹别克斯坦的阿姆河,是该国名贵的大型经济鱼类,现为野生种,已被列为乌国珍稀濒危鱼类。与我国鲃亚科鱼类相比,大鳞鲃为广温性鱼类,具有肉质鲜美,生长速度快,抗逆性强,耐盐碱等优良性状。我国的鲃亚科鱼类仅能生活在南方淡水水域,生存水温6℃以上,一般成熟鱼体重1～2.0 Kg,而大鳞鲃性成熟个体(5龄)体重3.0～5.0 Kg,生存水温1℃～30℃,其适宜淡水和半咸水生长。鉴于我国盐碱水域广阔,养殖品种单一,缺少大型经济鱼类,本课题组首次将大鳞鲃于2003年12月引入我国。目前,大鳞鲃在北方淡水池塘移植、驯化、养殖和人工繁殖成功。本文报道了大鳞鲃野生种和人工驯养种在池塘养殖条件下,其某些生物学特性。描述了该鱼的形态特征,栖息习性、生长、食性及繁殖特性。研究了人工繁殖F1的仔鱼和幼鱼生长状况以及对盐碱的耐受性。更多还原

【Abstract】 Barbus capito belongs to Cyprinidae family and Barbus genus.It originally inhabits in the Amu-Darya river of Uzbekistan.Barbus capito,as one of the most precious economic fishes in Uzbekistan,has been included into those species in danger.Compared with domestic Barbus,Barbus capito,living in normal waters,has good taste,quick growth,strong resisting ability and salt and alkali endurance.Domestic Barbus can survive only in waters of southern area,where water temperature is above 6℃.The average weight of its mature fish is between 1 and 2 Kg,while the weight of five-year old mature Barbus capito reaches 3-5 Kg.Barbus capito lives in fresh or brakish waters with temperature of 1-30℃.Considering broad salty waters,rare breeding species and lack of big-size economic fishes in our country,our project team firstly introduced Barbus capito into China in December 2003.Nowadays,it has been successfully domesticated,cultured and artificially propagated in ponds of Northern China. In this paper some biological features of wild and domestic species of Barbus capito are discussed,which include its diagnostic features,living environmental habits,feeding pattern and propagation characteristics.Both growth and abilities of larva and fingerlings from artificial propagation F1 in resisting salinity and bicarbonate alkalinity are studied respectively.更多还原
