In Kari Toft series on NRK Ut i naturen, you can see some rare underwater shots of the endangered Big Brown trout from Hunderfossen in Norway. This was recorded in 2015, and made the news in the main channel, NRK.
After some beautiful days in the Norwegian mountains, I returned home with some amazing underwater recordings of grayling, spawning in crystal clear water. This fantastic and funny relative of the Atlantic salmon has its own way of doing things. Enjoyable time spent by the river.
