The present state of salmon (Salmo salar L.) in Lithuania
According to historical data, salmon used to spawn in 16 rivers in Lithuania. At present wild salmon smolt production has been recorded in two rivers only, the Žeimena and Neris, both of them belonging to the Nemunas River basin. During the last decade the abundance of salmon migrating to the Nemuna...
