benthic macroinvertebrates in river are useful indicators for adverse impacts on the catchment and river ecosystems. these organisms integrate many ecological processes in catchment scale. in this study several single and multi metric biotic indices were used based on macroinvertebrates in order to evaluate the water quality of jajrood river. macroinvertebrates as well as water samples were col...

This research aims to determine the water quality profile of Genjong River based on physicochemical parameters and benthic macroinvertebrates as bioindicators. Sampling was carried out at four different location difference human activity in surrounding. The sampling done triple repetition for each station. station 1 is ecotourism (as reference site or positive control this study), Station 2 (li...

A biological assessment of the Tang Sorkh River (Iran) was studied from July 2013 to August 2014 using benthic macroinvertebrate communities. Samples were gathered every two months, from five stations using a Surber sampler( 30×30cm), fixed in formalin (4%) and then separated and identified in the laboratory. Environmental conditions (current velocity, temperature, depth, width, dissolve oxygen...

We used seven biotic indices to determine the water quality of Karabal Stream (Gediz River) in West Anatolia, Turkey. The were based on benthic macroinvertebrate and physicochemical parameters: Saprobi Index (SI), Biological Monitoring Working Party (BMWP), Average Score per Taxon (ASPT), Family Biotic (FBI), Belgian (BBI), EPT-Taxa [%] as Shannon-Weaver index (SWDI), Simpsons (SDI) Margalef (M...

The existence of Nepal's holy river, Bagmati, which flows through the core Kathmandu Valley has been menaced by many anthropogenic threats. It is necessary to identify how vulnerable it been. This research focuses on evaluation disturbance zonation analyze Bagmati River System’s spatial biological health. Benthic macroinvertebrates (BMIs) were used as indicators and sampled from upstream downst...
