把不同生境的一种鱼引进富营养的急流河口区总要产生一系列生物学和生态学问题。就白鲢而言,这不仅关系到它的摄食生物学和寄生虫学问题,而且还涉及到它对新的温度和盐度条件适应的生理生态学。虽已铁得一些在咸淡水中养殖白鲢的实际经验(Noak,1978;等),但能使该种鱼最初生存于该种河口区的生理生态机制仍不 Introduction of a species of fish from different habitats into the eutrophic jet stream has always led to a series of biological and ecological problems. In the case of silver carp, this relates not only to its feeding biology and parasitology issues, but also to its physiology that is adaptive to the new temperature and salinity conditions. Although some have had some practical experience in breeding silver carp in brackish water (Noak, 1978; et al.), The physiological and ecological mechanisms that allowed the fish to initially survive in such estuaries are still not
