This seems to be a young larva of Limnephilus. Although not clear in the picture, several ventral abdominal segments have chloride epithelia.

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.

This is not a Philopotamid. It is Psychomyiidae and it looks like Lype sp. but it is hard to see the sclerites on the mentum. It would be easy to ID with a close-up of the anal claws and ventral side of the head. Lype does not have long ventral teeth on the claws like Psychomyia sp., ventral teeth on the anal claws, that is.
