The trout season is here again

At last the trout season has opened on the Tweed again. I've only made it out for a couple of brief sessions but had a few on dries so I'm quite happy. Large dark olives have been trickling away and yesterday there was a good, but very brief, hatch of March Browns. I'm looking forward to getting plenty fishing in over the next few weeks.
This season we've got some interesting stuff to do, one of which is photographing trout for the Tweed Trout and Grayling Initiative's new fish recognition software. This will enable fish to be tracked for movement and growth. One pic of the head and one of the whole fish need to be taken. The length of the fish and place of capture are also noted, and sometimes scale samples taken. The picture of the head is then uploaded to the software and spots on the head are plotted. Once there is sufficient data entered it should start to show up repeat catches, fish growth and movement. The software can scan through hundreds of pictures in a few seconds and identify individual fish from the markings plotted in. This process relies heavily on angler participation so hopefully there will be enough people interested enough to make it work well. It should be interesting to see what information this project will produce over the next few seasons.
