Sorry Fishnut, I have to agree with JJP. Contrary to myth, suckers don't solely eat sport fish eggs. And as far as obtaining a permit, Sask Environment issues sucker permits for $5 which allow you to dipnet suckers in the spring.
While we're on the topic, have you boys and girls ever try eating canned suckers. WOW. If you like canned salmon, lookout. You Ukrainians out there know what I'm talking about.
