JimRed: re: searun brookies. Yes, they CAN be searun. There are a lot of resident brookie populations here in the east, but when they get the opportunity to run to the sea (estuaries, mainly), they can do so, and get big in a hurry. They also develop pinker flesh due to their diet. Some of our main rivers here in New Brunswick like the Miramichi and its tributaries have searun brookies run up each year. They can get to be about 7 lbs; generally more like 2 to 3 lbs. I have personally caught one over 25" long, that I would estimate at 6 lbs. But those same waters also have resident populations of smaller fish that don't run to the sea. They are 6 to 12" at maturity.
Now, there are lakes in Labrador (and other places) where landlocked (i.e. no access to the salt) brookies get large, too. One such lake (Igloo Lake) that I have fished now produces 10lb brookies due to a strict hook and release policy.
The searun brookies are locally called 'seatrout'. Adds to the confusion, since 'steelhead' are seatrout, searun browns are called 'seatrout', and I understand there is a warmwater coastal fish called a trout that is neither salmo nor salvelinus.

No wonder I've been confused about all these salt water trout. So basically a sea trout and speckled trout (aka "spec") are the same thing but neither is actually a trout? Kind of like Texans calling anything that's not a bass a perch.

Good one!
