Salmon upstream

1994/02/01 Elhuyar Zientzia Iturria: Elhuyar aldizkaria

In the Finnish basin of the Kemijoki River the highest industrial concentration of forest products is concentrated and pollution caused salmon to leave this river.

In recent times, due to environmental conservation measures, salmon has returned to this river. Logically, it would reach several rivers of Euskal Herria if the degree of cleaning is achieved.
