I wonder if anyone on the forum could help me, perhaps Mike or one of the other fishery owners.
The brown trout stocked on Aberdeen Angling Association water are easily identified by a blue spot on their underbelly. I was wondering how this was done, whether it was with some sort of marker pen or is it a dispenser. The reason I ask is that I was wondering if it was viable to mark salmon if catch and release was intended.
I feel this would be valuable for at least a couple of reasons. Primarily for the Don bailiffs to be able to identify quickly what month the fish were caught and so be able to breed like with like i.e. spring fish with spring fish. This could be easily done by putting a dot for a month (three dots for March, five for May etc.) It would also be interesting to instantly recognize whether a fish had already been caught and returned, in which case a second series of dots could be added.
All of this would depend on the availability of the dye, I am fairly sure it should last a season on a salmon as it seems to last at least that long on a trout.
