We are looking for one or two guys who fish regularly for Grayling to collect samples for us ,from anything you catch, Salmon ,Trout, Pike, Dace, Barble, etc and fill in info on scale envelope with a photograph of fish if possible.
These samples can tell us,age, rate of growth and previous spawning .
Below is a diagram how and where to take samples.
Below is a Salmon scale from a 19 lb fish
A lot of information can be obtained from Salmon scales like the one above including how long they have spent in fresh water and at sea.
Below are some diagrams of scale samples.
If you would like to help with this study can you please let us know and we will send out scale envelopes.
Until then you can download and print temporary ones.
Please include a picture if possible.
Any samples can be sent to
