摘　　要： 团头鲂是我国主要的大宗淡水养殖品种之一,其养殖规模在近10年不断扩大。团头鲂的营养物质需求主要以生长和营养缺乏症为评价指标。而营养物质对鱼类健康,如免疫反应和抗病力等影响的研究尚不充分。一般认为,饲料中营养物质搭配合理、品质优良有利于维持鱼类生理健康,并能保护养殖水环境。此外,一些营养物质如维生素,在鱼类的免疫机制中发挥重要作用。未来水产饲料应具有促进水产动物生长和维持健康的双重作用,通过营养调控预防鱼类疾病是保证水产养殖可持续发展的重要策略之一。本研究综述了团头鲂对蛋白质、脂肪、碳水化合物、维生素和矿物质营养需求的研究进展,以及饲料营养元素对团头鲂免疫力及抗病力影响的最新报道,以期为团头鲂高效配合饲料的开发提供科学参考。 Blunt snout bream（ Megalobrama amblycephala） is one of the major freshw ater aquaculture species in China,and aquaculture of this species has been rapidly expanded in the last decade. Efforts have been made over the past two decades,especially in the case of farmed fish species,to understand the dietary nutritional requirement. How ever,dietary nutritional requirements have generally been based on growth and deficiency symptoms,rather than on the health status indicators including immune responses and disease resistance. Generally,the physiological outcomes attributed to these nutrients or additives are presumed to be translated to good health and protected water environment. In addition,some ingredients such as vitamin have showed to play an important role in immunity function of fish. Aqua-feeds of the future are expected to impart dual benefits of good growth and health to the farmed organism,and preventive health care through nutritional means is certainly a strategy to ensure sustainability in environment friendly aquaculture. Indeed,this review addressed these concerns by providing an overview of published nutrient requirements（ dietary protein,lipid,carbohydrate,vitamins and minerals） on the grow th and the links betw een nutrition,immune response and resistance to diseases of M. amblycephala,and the influence of water temperature on the determination of these nutrients requirement in order to provide scientific references for efficient development of compound feed for this species.
