“…The establishment of reference conditions was based on identification of minimally disturbed landuse sites that represented the best physical, chemical, biological conditions (ZHU and CHANG, 2008;QADIR and MALIK, 2008). First, we considered sites to be "reference quality" if the rivers had better riparian vegetation, no towns or human communities along the river bank, no gravel-mining activity or hydrologic modification in the watershed, and no wastewater treatment discharges (BLOCKSOM et al, 2002;MORLEY and KARR, 2002).…”

The aim of this study is to develop a benthic index of biotic integrity (B-IBI) to help understand how the increasing anthropogenic pressure may impact the subtropical Xiangxi River in China. Benthic macroinvertebrate and environmental surveys were conducted at 77 sites in early summer 2004. Each collection site was categorized as reference or impaired based on physical, chemical, biological, and land-use information. Six non-redundant metrics from 35 metrics were used to differentiate between reference and impaired sites. We selected six metrics for the final IBI. The scoring criteria of each metric were normalized based on the quadrisection and 0-10 scaling systems. Both scaling methods were used to assess the aquatic health of each site in the Xiangxi River watershed. The results showed that most sites were in fairly poor condition. Furthermore, we identified the relationship between B-IBI metrics, water-quality, and land-use variables with a principal component analysis. A composite of nutrients and land-use intensity explained most variances. These results suggest that the B-IBI may be a suitable method for assessing river conditions within the subtropical Xiangxi River in central China. IntroductionAquatic ecosystems, and their biological assemblages, continued to be degraded globally from anthropogenic activities in their watersheds (GANASAN and HUGHES, 1998;KARR, 1999). Part of the decline in water resources stems from insufficient consideration of their biological structure and function (KARR, 1999;STODDARD et al., 2006). Some factors have been reported which are linked to river degradation. Physical and chemical factors may be related to biological changes (MULLINS, 1999). Water quality may only partially reflect environmental impact (BOZZETTI and SCHULZ, 2004). Researchers increasingly include quantitative biological indicators (JOY and DEATH, 2004;ROSET et al., 2007). Biological indicators may reflect the intensity of anthropogenic stress and have been used as a tool in risk assessment and evaluation of human induced changes in freshwater ecosystem (KAMDEN-TOHAM and TEUGELS, 1999

ÖzSu, canlıların temel bileşeni olması ve tüm canlılık faaliyetlerinde ihtiyaç duyulması nedeniyle Dünyadaki en önemli bileşiktir. Su, bazı canlılar için aynı zamanda yaşamlarının belli bir kısmını veya tamamını geçirdikleri ideal bir yaşam ortamıdır. Günümüz Dünyasında bir milyara yakın insanın temiz içme suyuna sahip olmadığı ve 2,5 milyar civarındaki insanın ise kullandıkları su kaynaklarında hijyen ve sanitasyon sorunu olduğu tahmin edilmektedir. Yenilenebilir bir kaynak olan suyun sürdürülebilir kullanımının sağlanması sadece miktarının değil kalitesinin de korunması ile mümkündür. Ekosistem kalitesinin değerlendirilmesinde ve izlenmesinde Biyotik İndekslerin kullanımı yakın bir geçmişe sahipken önemi gün geçtikçe artmaktadır. Index of Biotic Integrity for Evaluation and Monitoring of Water Quality: Using Fish Biotic Integrity Index AbstractWater is most important compounds in the world due to the main component of living and needed activities in all of life. Water is also an ideal living environment they spend a certain part or all of their life for some creatures. Today nearly billion people do not reach to a with clean drinking water and around 2.5 billion people have hygiene and sanitation problems of the water they use is in the world. Ensuring the sustainable use of renewable water resources, which is possible with the protection of the quality of not only the quantity. The importance of ecosystem quality assessment and monitoring the use of a biotic index is increasing day by day while the recent past. Fishes are considered as an important indicator organisms in this index. The use of biological indices in Turkey is still in its early stages indexes are used as biological elements of the fish is not yet implemented.

“…This project was designed to provide scientific support for controlling and managing water pollution in China. Thus, many fish-based methods including IBI have been used to evaluate the aquatic condition of China (Zheng 2006;Zhu and Chang 2008). Despite many studies applying IBI in China, there were still some problems in the application.…”

With economic development in China, humaninduced 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.
