The sea dragon has returned - what else does the Black Sea conceal.

Despite all the difficulties faced by the Black Sea, life continues within it. One species of fish, which has long been considered rare, is now reappearing in the catches of fishermen. This species, known as the sea dragon, has to some extent restored its population.

However, along with the return of native fish species, the Black Sea also faces the emergence of foreign species. One such species is the Korean rockfish, which has become increasingly common on fishermen's hooks along the coast of Odessa. The presence of this fish poses a threat to the sea's ecosystem but can also present an opportunity for controlling their population.

The Black Sea is witnessing both the return of native fish species and the emergence of foreign species, which affects the sea's ecosystem and fishing opportunities in the region.
