Mongolia is currently undergoing a rapid socioeconomic transition with extensive development driven by increased mineral resource extraction and large scale agriculture and pastoral expansion. There has also been unprecedented urbanisation and continued population growth that has placed added pressure on the ageing public infrastructure including power stations and waste water treatment plants. As a result, the country’s pristine landscapes, including its vast freshwater ecosystems, are now facing widespread degradation, contamination and species losses in the most impacted regions. The proposed large-scale dams and imminent climate change effects will further damage these fragile ecosystems. With a number of rivers and lakes deteriorating, resident aquatic communities, including unique fish species, have suffered significant population declines. However, a more substantial threat currently facing these fish populations is the rapid and largely unregulated rise in fishing activities within an emerging recreational fishery. Although historically fish capture and consumption has not been a traditional part of the Mongolian diet or culture, this is changing rapidly. Therefore a comprehensive set of research projects were developed and implemented across Mongolia, to gather essential information on this new fishery, while also addressing existing knowledge gaps regarding the spatial ecology and genetic structure of the main target species. In addition, a potential human health risk was evident due to the increased consumption of locally caught fish species from a heavily impacted river basin, and thus this was also investigated. Overall, the collective aim of this fisheries research was to increase the scientific understanding and knowledge across a range of issues and ultimately advise authorities on improving current management regulations and conservation strategies. It is hoped that the recommendations can assist in safeguarding the future sustainability and resilience of the threatened fish populations and the emerging recreational fishery across Mongolia for the future.
