Unusual trout spawning in Lake Locknesjön caught on camera

The County Administrative Board of Jämtland County has had underwater cameras deployed in Lake Locknesjön, a couple of miles outside Östersund, for just over a month in order to document unusual trout spawning. It involves trout spawning in the middle of the lake instead of seeking out gravel bottoms in running water, which is the norm.

A fish biologist at the County Administrative Board says he is not aware of this behaviour from other lakes. Some of the trout in Lake Locknesjön spawn in streams or in the lake's outflow into the River Forsa, but why some choose to spawn in the lake is not yet known. SVT Nyheter Jämtland
