In 2023, an ecological assessment of the state of two rivers, part of the Maritsa river basin in Bulgaria, was carried out. For the study, benthic macroinvertebrate organisms (macrozoobenthos) were collected during the spring season from the Luda Yana River in the area of the village of Popintsi (Panagyurishte Municipality, Pazardzhik Region) and from the Chepelarska River in the area of Katunitsa village (Sadovo Municipality, Plovdiv Region), designated as biotopes. 512 and 712 specimens of benthic macroinvertebrates were collected from the Popintsi biotope and the Katunitsa biotope, respectively. The macroinvertebrate taxa found from the Popintsi biotope are belonging to 12 orders: Amphipoda, Annelida, Coleoptera, Diptera, Ephemeroptera, Gastropoda, Hemiptera, Lepidoptera, Lumbriculida, Odonata, Plecoptera, Trichoptera. Macroinvertebrates from the Katunitsa biotope are belonging to 11 orders: Amphipoda, Annelida, Diptera, Ephemeroptera, Gastropoda, Hemiptera, Lepidoptera, Lumbriculida, Odonata, Plecoptera, Trichoptera.
