Mariculture production in Crimea, including shrimp, mussels, and oysters, has seen a decline over the first nine months of 2023, with production falling to over 1,030 tons from over 1,330 tons in the same period in 2022. The decrease is attributed to difficulties in the delivery of fish seeding material, sourced from countries such as Spain, France, and Thailand, and the closure of parts of the Black Sea and Lake Donuzlav due to a special military operation.
