Project OPKK Monitoring - Freshwater Fish observations collected for the development of monitoring programs during 2022-2023

Within the framework of the OPKK project "Development of the System for Monitoring the Status of Species and Habitat Types" - GROUP 8: "Creation and Development of Monitoring Programs for Freshwater Fish with Capacity Building for Stakeholders in the Monitoring and Reporting System," new data on the abundance and distribution of 48 freshwater fish species of interest to the EU were gathered. These data were collected using methods described in the newly proposed monitoring programs, aiming to test their adequacy for long-term monitoring of species conservation status. This dataset includes observations of various species over a period 2022-2023.
