This article first appeared in the WTT Autumn 2018 newsletter, but as it is spawning time again we thought it was worth repeating!
A couple of new things for this year:
An excellent podcast by Andrew Griffiths called ‘The Trout and the Heron’. Just eight minutes of wonderful description, recorded beside a river at spawning time.
And this wonderful video from the Ness Fisheries Board (below). It is well documented for both salmon and sea trout that small young males (called ‘precocious parr’) will sneak in and fertilise the eggs of hen fish whilst the large adult males are busy fighting each other away.
