The Caspian Sea, shared by five countries - Russia, Azerbaijan, Iran, Kazakhstan, and Turkmenistan - has a unique commission dedicated to the conservation and sustainable use of its aquatic life, particularly focusing on sturgeons. This commission, a key effort in international cooperation, oversees the regulation of fishing quotas and the enforcement of anti-poaching measures. Despite the quotas, a moratorium remains on the commercial fishing of sturgeons due to their critically low numbers and the need for conservation. The sea also supports substantial catches of other fish species, with sprats being the most abundant. The countries party to the agreement exchange research findings and collaborate on aquaculture development, aiming to balance fishing with the preservation of biodiversity in the Caspian Sea.
