Hi there
In caught this ( and a couple of others) on a czech nymph on the itchen near Winchester in december and of course carefully returned it.
However its been buggung me ever since as to whether its a Sea Trout , Brown trout or salmon parr
.also the mouth angle & tail looks a little different .
I have had many brown trout of this size before but they have all had v different markings and colourings - and certainly no fingerprint type markings.
Sorry the pictures are not great but any help in positively identifying the species would be greatly appreciated to put me out my misery !
Thanks
Regards
Paul
