In an effort to preserve the endangered European river eel, the Kaliningrad Region in Russia plans to release 2.7 million juvenile eels into the Kaliningrad and Curonian Lagoons in 2024. This initiative is part of a larger conservation effort that includes support from CITES, ICES, and the government of the Kaliningrad region. The plan also includes limiting the total allowable catch and implementing a six-month fishing ban. The European river eel, a critically endangered species that spends most of its life in fresh water and goes to the sea to spawn, is native to fresh and brackish waters in the eastern Atlantic Ocean and the Mediterranean Sea.
