Approximately 63 thousand young eels were released into the Vistula Lagoon in Kaliningrad to restore their population. Eels have been a major fishery in the region, but factors like mass catching and dam construction have severely reduced catches to about 15 tons per year. Plans are in place to raise and release millions of juvenile eels to help replenish the population, and a company from Kaliningrad will create a complex for growing brown trout and eel as part of a government program.
