Sea trout spawning

We had  job to do in the Tomnavoulin area yesterday and once we were finished we had a quick look to see if there were any spawning sea trout to be seen. The answer was yes with redds and spawning fish present in the Livet. The water temperature was still 8oC yesterday but the extra water over the weekend was perfect timing to get the sea trout started.

Multiple sea trout redds in the Livet. Not the best photo, I should have fitted the polarising filter but the light was poor.

After the Livet we had a quck look in the Tervie, a noted sea trout (and salmon) burn. We walked a few hundred metres finding a few redds. There was evidence that the otters had taken advantage of the annual influx of big fish.

A short distance away Polly came across a cascass. This was also a sea trout but a male this time.

Remains of a cock sea trout. The fish was probably about 1.5lb when fresh. The photo shows how the shape of tha anal fin can be used to aid the identification between salmon and sea trout. In a sea trout the end of the outer ray of the anal fin is the one that extends closest ot he tail when the fin in pressed flat against the body.

In a sea trout the tip of the outer ray on the anal fin is the one that extends closest to the tail when the fin in pressed flat against the body. On a salmon there are inner rays which are closer to the tail.

The sea trout spawning is probably only getting underway now; the forecast rain for Friday should see good numbers of fish in the burns.

On the way home we stopped at the Packhorse Bridge on the Livet. The woodland autumn colours are fantastic this year, I can’t remember another year with such rich colours, especially the Aspen which are vivid yellow at present.

It was a rubbish day for taking photos, pity the sun wouldn't shine so we could appreciate the colours fully.

    Thanks for the update. Very interesting, especially the little snippet about the identification using the fin.
