27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Most of the pictures on this site are great, however, in some cases, for instance in the case of the mayfly types it would be so great if there was some indication of average size of the depicted specimen.Mayflies in their enormous array of sizes are hard to distinguish because colour alone often will not do it.
Thanks, A.K.
