Ukraine is planning to develop mariculture businesses in the Khadzhibey and Sukh estuaries in Odesa, as part of a two-year experimental project. The project will involve leasing inland marine waters for mariculture through auctions, with the aim of creating a transparent lease mechanism. The estuaries have the potential for marine aquaculture due to their deep waters and high productivity. The industry has the potential to supply the domestic market with valuable food and seafood, increase employment, develop small and medium-sized businesses, and economic development. The war in 2022 resulted in a stop or partial stop of industrial fishing for about 80% of users of aquatic biological resources.
