The main goals of PTLim are:
- Supporting scientific, scientific-technical, engineering, monitoring, training and teaching activities in all areas of limnology, especially those related to natural and anthropogenic transformations of lakes, their protection and management, and improving methods of its effective use in environmental protection and water management.
- Developing knowledge in the field of limnology and promoting this science as one of the fields of Earth sciences, including:
- The study of physical, chemical and biological changes in lakes, their relationship to climate and other physical and geographical factors, and the interrelationships between them.
- Study of the evolution of lakes and their morphometric changes.
- Further investigation of the role of lakes in shaping water circulation in the catchment and their relationship with surface and groundwater.
- Understanding the limnological consequences of the use of lake water resources and their qualitative and quantitative changes occurring under the influence of natural and anthropogenic factors.
- Providing a scientific basis for optimal use and improvement of the quality of water resources in lake ecosystems, including knowledge in the field of engineering, lake water resource management and planning.
- Improving methods in both basic and applied limnological research.
- Creating favorable conditions for discussion, exchange of views and publication of scientific research results.
- Initiating, supporting and coordinating scientific research aimed at solving limnological problems requiring interdisciplinary, interregional or international cooperation.
- Representing the interests of members in their professional activities and towards the authorities, society and other national and foreign associations.
