The main research area of the Research Laboratory is the development of theoretical and practical foundations for the formation and functioning of hydrobiocenoses under anthropogenic pressure on aquatic ecosystems, with the aim of applying them to measures for regulating the development of aquatic biological resources and the condition of aquatic ecosystems as a whole.

The scientific and practical areas of the Research Laboratory include:

development of regulations for the use of water bodies;
development of scientific and biological justifications;
minimization of the negative impact of anthropogenic factors on aquatic ecosystems;
assessment of water quality;
research in fish farming and aquaculture;
study of biological invasions and development of measures to minimize their negative impact;
bioindication of the quality of the aquatic environment.

The Research Laboratory of Hydrobiology, Ichthyology and Radiobiology has a wide range of equipment for conducting hydrobiological research using generally accepted methods, as well as optical instruments, computer equipment and office equipment. The laboratory uses modern microscopes, including a trinocular microscope with optical equipment, as well as digital CMOS cameras for microscopes.

A “Praktik” echo sounder, JBL Testlab hydrochemical kits, a laboratory centrifuge, a photoelectric colorimeter, a water bath, a spectrophotometer, an electric aquadistiller, an automatic microtome, and Nageotte, Bogorov and Goryaev chambers are also used for research.

The laboratory staff have improved methods for staining blood and sperm smears of fish, as confirmed by Ukrainian utility model patents.

In June 2023, Certificate No. ПЧ 06-2/1150-2023 dated 14 July 2023 was obtained, certifying the technical competence of the Research Laboratory and its compliance with the requirements of DSTU ISO 10012:2005, “Measurement Management Systems — Requirements for Measurement Processes and Measuring Equipment,” for determining hydrobiological and parasitological parameters. The certificate confirms the competence of the personnel and compliance with metrological requirements and measurement process standards.
