The article highlights the economic impact of the Russian invasion of Ukraine on the fish farming sector in Europe, as reported by Apromar. The sector is facing a crisis due to increased costs of feed, energy, and supplemental oxygen for fish farming, primarily due to Ukraine's importance in producing raw materials for fish feed and the war's disruption of supply chains. Apromar is seeking aid and measures such as capping electricity prices from the European Union to mitigate these challenges. The rise in production costs is not being matched by a commensurate increase in the price of farmed fish, especially in Ukraine, where the war has led to potential reductions in fish consumption among low-income families.
