Purpose. Rearing of the European eel (Anguilla anguilla) is a promising area of aquaculture, the development of which in Ukraine and the world is constrained by several factors. Spawning, egg incubation, lack of a stable source of supply of fish seeds – these and other problems, as well as the importance of such studies form a basis for finding approaches for their solution and conducting new large-scale studies. This area attracts attention of scientists, there are certain results and achievements; however, they are still not enough to solve the problems of artificial reproduction of the European eel. Findings. The authors revised, analysed and systematized literature sources focused on the study of the European eel. As a result, it was possible to identify the main achievements and shortcomings in this area, which are promising for further study. In addition, we identified some obstacles faced by scientists and analysed available methods for their solving. Practical value. This review can be used to stimulate new studies and technological development towards industrial cultivation of eel in Ukraine, which will allow reducing the impact on natural populations of this species and stabilize its number in the natural environment. In addition, the authors of the article intend to draw attention of scientists and manufacturers to the perspectives and problems of growing and studying the European eel.
