Report of the FAO/TCF Workshop on Advanced Methods for the Analysis of Hard Structures of Fish to Assess Fish Migration and Feeding Behaviour in View of Improved Management
2016
The FAO/TCF workshop, held in Mongolia from 7 - 13 October 2015, was attended by government officials and representatives of the Mongolian Academy of Sciences, universities, the Eg River Hydropower Project Unit, the private sector and the Taimen Conservation Fund. Classroom sessions provided a broad overview of the background and theoretical aspects of the isotope analysis. Practical field work pertained to identifying and characterizing relevant sampling sites, sampling of fish and extracting and preserving of hard structures. Also water samples were taken. State-of-the-art knowledge concerning the isotope analysis in fish hard parts was presented to raise awareness of the benefits of this technique for the characterization of fish migration and feeding behaviour, and to stimulate informed discussions about fish migrations, fish protection, aquatic habitat and living aquatic resources management, and related issues in view of an improved integrated basin management. Local aquatic environmental issues, potential human-induced threats to the aquatic environment, and especially actual and potential impacts on fish and fisheries in the Eg/Selenge catchment, were scrutinised. Potential approaches based on science were discussed. There was agreement that further aquatic environmental studies would be beneficial to better understand river-related processes and potential implications of planned measures in the Eg/Selenge basin.
