人们普遍认为，人类活动导致陆地和水生来源的细泥沙输入量增加，会对水生生态系统产生负面影响。在河流中，淡水鱼受到细小的沉积物压力造成的一系列影响。迄今为止，关于细沉积物对鱼类影响的研究主要集中在相对较少的科内，特别是鲑鱼科。本文回顾了描述细小沉积物对淡水鱼类的间接和直接影响的文献，以期有助于加深人们对人类活动对淡水生态系统影响的理解。我们确定了鱼类种群对细泥沙负荷增加所表现出的负面反应的因果机制，以及不同鱼类之间的差异。版权所有 (C) 2011 John Wiley & Sons, Ltd.
Elevated fine sediment input from terrestrial and aquatic sources as a result of anthropogenic activity is widely recognized to impact negatively on aquatic ecosystems. In rivers, freshwater fish are exposed to a range of impacts resulting from fine sediment pressures. To date, research on the effects of fine sediments on fish has been concentrated within relatively few families, notably the salmonidae. This paper reviews the literature describing indirect and direct impacts of fine sediment on freshwater fish as a contribution towards enhancing the understanding of the impacts of anthropogenic activities on freshwater ecosystems. We identify the causal mechanisms that underpin the observed negative response exhibited by fish populations to enhanced fine sediment loads, and the variability across different fish species.
