The colors are throwing us off.

 

What say yea?.....No eye mascara.  My guess is landlocked salmon???

 

Thanks in advance 

 

My guess is a brown trout. 

Salmon is my thought.

Looking at it, I'd say Brown Trout as well. There's a definite 'halo' around a number of the spots and Atlantic Salmon, the most probable Salmon species that might be in NH, doesn't have that halo. And while Brown Trout is mostly a golden background color, silver is not unknown.

Another view

Okay, that one shows the golden background color up near the dorsal side. I'd say it's definitely a Brownie.

I would agree that it's a Brown trout

This might help:

I got it from https://wildlife.state.nh.us/fishing/salmon-browntrout.html

Looks like a skinny male salmon to me.  I’m simply going off of the body shape, and the look of the tail. Long and slender, and sharp points on the ends of the tail.  

 

Brown trout and landlocked salmon can share near identical colors from silver to brown, and lots of other overlapping traits.  There have been cases where the biologists needed DNA tests to confirm species. This is probably not one of those cases,  but My judgement says salmon. 

Slight fork in the tail and the jaw is only to the eye, I'd guess LLS based on the NHF&G website descriptions. Either way, nice fish

Yesterday NHFG officer confirmed LLS
