With more and more Atlantic Salmon showing up in the systems, I figured a post dedicated to Atlantic identification would be good to have so everyone can learn how to identify an Atlantic and not mistake it for a brown or something else. When you do catch one, do your best to keep it in the water, work fast and remember the limit is zero on Lake Ontario tributaries.
Here is a link to the MNR site RE : Atlantic ID.
Here is the CRAA Atlantic Salmon ID poster.
Here are two shots to help identify - note the mouth is very slender and the jaw doesn't extend past the the eye.
This body shot shows a couple more distinct features - no spots on a forked tail ( brown trout have square tails ) and the tailing section ( caudal peduncle ) is narrow and long. X like spotting mostly on the top half of the fish above the lateral line ( middle of the fish ) with a few spots on its face.
