Eels taken by car to the Vistula Lagoon. Scientists helped on the way to spawning

The ministry indicated that the transfer of fish is intended to reduce the risk of their death and fishing pressure on the Russian side of the Vistula Lagoon.

The eels were caught using fyke traps, i.e. trapping tools considered safe for fish. They were then briefly placed in tanks with appropriately oxygenated water.

Before leaving, specialists checked, among others: fish maturity, condition and keeping conditions. Individuals ready for spawning migration were weighed and then transported in cars equipped with special pools. Ultimately, they were released into the Bay of Gdańsk, on the open sea side.

Scientists will track fish migration

The operation was carried out from October 5 to 27 as part of the MIGRATIONS/26 project. It was handled by the Maritime Research Institute - National Research Institute. In total, the transport included 9,110 silver eels, i.e. adults starting their way to spawning grounds.

One hundred fish were equipped with acoustic transmitters. Signals from these devices will allow scientists to observe their further route and collect data needed to protect the species.

The project is part of the updated Eel Management Plan in Poland, part of European efforts to rebuild the population. The goal is to provide conditions that will allow at least 40 percent. silver eels migrate to the Sargasso Sea - compared to levels before intensified human activity and population collapse. The initiative is financed by the European Funds for Fisheries program for 2021-2027.
