露斯塔野鲮(以下简称野鲮)是南亚次大陆和东南亚国家淡水养殖主要鱼类之一。1978年引进我国,1981年在我国人工繁殖成功。 Alikunhi报道野鲮摄食植物碎屑、浮游藻类和泥沙等。但对当年鱼消化系统的发育和食性还未见有系统的报道。为探索野鲮在我国的养殖方式,更好地发展其养殖,作者对该鱼消化系统的发育和食性的变化进行了较系统的观察。 Rothschild 鲮 (hereinafter referred to as 鲮) is one of the major freshwater aquaculture species in the South Asian subcontinent and Southeast Asian countries.
