landlocked counterparts?
Where are you fishing?
Landlocked means they can't get out to the ocean.
But generally, trout and Kokanee are much smaller I have caught trout over 7 lbs but not in the lower mainland.
Mature steelhead and sockeye will be in the 4-10 lb range (or more for steelhead) depending on the run.
Local trout and kokanee will be 2lbs or less and that's probably pushing it for most lower mainland lakes ( with the odd exception)
Smolt steelhead are often confused for trout but you'd mostly find them in the tributaries; creeks, streams that feed out of some of the larger lakes.
Someone else will jump in here 'cuz although I fish the local rivers most of my lake fishing is in the interior.
But, if I was fishing one of the lower mainland lakes today I wouldn't be too worried about catching one.
Plus you could google: (insert fish species here) pictures.
and try to find the distinguishing features.
A lot of folks can't even figure out the different species of trout; rainbow,dollies,bull.........
