The Biological Monitoring Working Party (BMWP) score system was introduced in 1980 to provide an index of river water quality for England and Wales based on aquatic macro-invertebrates. The score allocated to each taxon was set by a group of expert river biologists based upon their collective experience of the taxon’s sensitivity to organic pollution (Hawkes, 1997). This paper describes an obje...

The use of aquatic macroinvertebrates as bio-indicators in water quality studies has increased considerably over the last decade in Costa Rica, and standard biomonitoring methods have now been formulated at the national level. Nevertheless, questions remain about the effectiveness of different methods of sampling freshwater benthic assemblages, and how sampling intensity may influence biomonito...

Score-based biotic indices are widely used to evaluate the water quality of streams and rivers. Few adaptations of these indices have been done for South America because there is a lack of knowledge on macroinvertebrate taxonomy, distribution and tolerance to pollution in the region. Several areas in the Andes are densely populated and there is need for methods to assess the impact of increasin...

Including or excluding rare taxa in bioassessment is a controversial topic, which essentially affects the reliability and accuracy of the result. In the present paper, we hypothesize that biological indices such as Shannon-Wiener index, Simpson's index, Margalef index, evenness, BMWP (biological monitoring working party), and ASPT (Average Score Per Taxon) respond differently to rare taxa exclu...

This study is part of the effort to test and to establish Rapid Bioassessment Protocols (RBP) using benthic macroinvertebrates as indicators of the water quality of wadeable streams in south-east Brazil. We compared the cost-effectiveness of sampling devices frequently used in RBPs, Surber and Kick-net samplers, and of three mesh sizes (125, 250 and 500 microm). A total of 126,815 benthic macro...

we investigated the environmental impact of trout farm discharge on zayandeh-rud river. three farms with different production capacities; 250, 25 and 70 tones were assigned to this study. five sampling sites were designated to each farm. benthic macroinvertebrates were collected in autumn, winter, and spring using the quantitative techniques. a total of 11 classes, 16 orders and 53 families&apo...

Pindo Grande River water quality was analyzed during rainy seasons of 2014 and 2017 dry 2015 2016. Specimens were collected using surber net, kick net manual stone collection, from five different sites along the river. In laboratory, specimens identified to lowest possible taxonomic level. Taxon richness, abundance, diversity, trophic niches, Biological Monitoring Working Party for Colombia (BM...
