Increasing the Oxygen Content of the Kalajoki River

  • Esko Lakso


In Finland, the need to raise the oxygen content of waters is most evident in late winter when the ice cover prevents the water from receiving oxygen from the air. In Central and Southern Finland, the watercourses become ice-bound in November-December, and the ice melts in April–May.
