Thesis structere: introduction, 4 chapters, conclusions and recommendations, 326 cited literature, 150 pages, 20 figures, 7 tables, 3 annexes (21 pages 193 figures). The obtained results have been published in 15 scientific works and 3 projects.
The domain of study: 165.03. Ichthyology.
Research purpose. Evaluation of the ichthyofaunistic diversity in the basin of river Gianh, and elaboration of recommendations for protection and durable use of fish resources.
Objectives. Inventory of fish fauna diversity in the basin of river Gianh from Vietnam; description of morphometric and meristic characters of the identified species; analysis of spatial repartition; identification of fish species with high economic value, of the invasive and rare alogens ones in the basin of river Gianh.
Novelty and scientific originality. For the first time there has been composed a complete list of fish species from the basin of river Gianh and there have been described the morphological characters of identified taxons. There have been analyzed peculiarities of spatial distribution of the fish species in the basin of river Gianh. The species have been systematized according to their economic value, origin, and national and international status of rarity. There have been identified 3 new species for research: Schistura kottelati Tuan et al., 2015; Carassioides phongnhaensis Tu & Tuan, 2003 and Cyprinus hieni Tu & Tuan, 2003.
The important scientific problem solved in the thesis consists in the actualization of ichthyofauna diversity and the peculiarities of distribution of fish species in the basin of river Gianh which led to the elaboration of scientific-practical recommendations for the conservation and rational use of fisheries.
Theoretical significance. The scientific information about the diversity of ichthyophauna in the basin of river Gianh and the National Park Phong Nha - Ke Bang was updated. There were identified and described 3 new fish species for science. There were analized the metric and meristic characters of the caught species. The information about the fish species has been systematized according to peculiarities of spatial distribution, economic value, and origin and rarity status designated by national and international Red List (IUCN).
Practical value of the work. The obtained results served as scientific basis for developing recommendations for the protection and sustainable use of fish resources in the basin of river Gianh.
Implementation of the results. The obtained results on the topic of the thesis were implemented in specialized institutions of Vietnam: Society of Hunters and Fishermen, Forestry Protection Department, Department of Science and Technology, and also in the teaching process at University Vinh from Vietnam and Moldova State University.
