Hi fishermen i know you guys are wondering and asking what do you use lamprey for. Well let me tell you i'm from cailfornia we use lamprey for sturgeon bait sometime there is a short on bait at the bait store. Lamprey only come up the river in the spring to spawn so that is the only time you could get them. I read alot about how it is a problem you guys are having with the lamprey and no one has no use for them. Will i have use for them i wish we have as much lamprey as minnesota does so i could catch as many as i want. Thanks guys for responding and if anyone has a question feel free to ask.
