The article highlights the state of the fishery complex in the Krasnodar Territory, focusing on the dynamics of commercial fish production and the challenges faced by fishermen in the Azov-Black Sea basin. It notes a decrease in production volume in the basin due to factors such as competition, climate change, and ecological issues, with an increase in the catch of less valuable fish species. Scientists warn of the potential dominance of these species in the Black and Azov Seas due to global warming and other factors, and call for increased production of marine and brackish-water species and a change in fishing areas to address the challenges. The article also mentions the competition from Crimean colleagues and the impact of climate change on natural reservoirs and the Azov Sea's ecology and biodiversity.
