| Summary: | Abstract This bibliographic review work presents a compilation of the bioindicators of water quality, its main advantages and disadvantages; the types of bioindicators are detailed, for example bacteria, protozoa, phytoplankton, macrophytes, fish and aquatic macroinvertebrates. It is important to know how the collection of macroinvertebrates is carried out, in the case of environments with running or sleeping waters, not very deep, a net is used, while for environments with currents or calm but deep waters, the use of dredgers is It is recommended that, after collection, it should be kept in appropriate containers until the types of bioindicators that were collected can be identified with the help of a microscope. It can be said that the use of aquatic macroinvertebrates as indicators of water quality is very widespread throughout the world, so their evolution has increased as they already have taxonomic species determined for different quality states. That is why the objective of this research is to know the evolutionary importance of aquatic macroinvertebrates as indicators of water quality, at the same time the advantages and disadvantages of the use of bioindicators, compared to physical-chemical methods.
