520			_aWith economic development in China, human-induced pressures on aquatic environments have grown and created an urgent need for tools measuring the ecological condition of aquatic systems. However, biological indicators for wadeable streams in China were poorly developed. This study developed and validated a multi-metric index of fish assemblages for wadeable streams of southern China to meet the requirement of the water project which has been carried on in China in recent years. Fifty-seven stream sites were sampled in April–May and November–December 2010 to develop an index of biotic integrity. A set of 45 candidate metrics were evaluated for range, responsiveness and redundancy, resulting in the selection of six metrics for the index: number of native species, number of rheophilic species, proportion of benthic riffle individuals, number of lithophilic species, number of omnivore species, and number of fish per hour sampling. The publicly available census data were used as independent data set to validate our method. Twenty-three sites were assessed as subject to significant (SP) or non-significant pressures (NSP) based on anthropogenic pressure evaluation. Our index performed well in discriminating NSP and SP sites, which suggested that our method could provide an accurate measure for wadeable streams ecosystem condition. We believe this integrated approach would meet the requirements for the water projects of China, and the process of developing the method could be used as reference for managing the subtropical streams in other areas of China or other states.
