Another forage species is always desirable, so it will be worth it.
I stocked around 200 that I dip netted from a friend's pond. Though my pond was new and had no plant cover at the time, they established great. By year 3, I could dip net anywhere around the banks and catch as many as 2 dozen per swipe. I net them and use them for bait, and they beat just about all other baits. I find shrimp in the gullets of lots of my BG and BC, and it's common to catch up to 14" LMB on the little guys while fishing for BG.
I have Mississippi grass shrimp (palaemonetes kadiakensis), and would think Canada is at the very edge of their range.
