Negative impacts of the local fat plant (Doyasan) (Erzurum, Turkey) on the
population and variety of Aquatic Coleoptera at Karasu River were supported by the
physico-chemical parameters. Aquatic Coleoptera species, sampled before and after
discharge point of plant, belonging to Helophoridae, Hydrophilidae, Hydrochidae,
Dytiscidae and Hydraenidae families, were identified and listed at species level. Both
physical (total dissolved solids, temperature) and chemical (pH, dissolved oxygen,
conductivity, hardness, organic matter, chloride, phosphate and some metal ions)
parameters of two inhabited water were measured and compared.
