The status of natural populations of wild marine elasmobranch, whose number is estimated as 500 species, appears underexplored, the information on them being absent in certain cases. By contrast, their number and biodiversity are extremely decreasing due to climate changes, marine pollution resulting from human activities, and overfishing. The state of health of those species is also deteriorating which affects populations´ dynamics. Therefore, the research of marine elasmobranches is vital and requires the development of adequate methods and approaches to the evaluation of their wild populations. The article outlines contemporary approaches to the evaluation of the status of three Black Sea elasmobranches. The study is aimed at the development of measures to protect the species, to organize their optimal catch as well as to close fishing of certain species that are rare or at risk of extinction.
