Minn. Stat. § 17.4994: SUCKER EGGS.

Sucker eggs may be taken from public waters with a sucker egg license endorsement for the fee prescribed in section 97A.475, subdivision 29. Taking sucker eggs from public waters is subject to chapter 97C and may be supervised by the commissioner. The commissioner may limit the amount of sucker eggs that a person with a sucker egg license endorsement may take based on the number of sucker eggs taken historically by the licensee, new requests for eggs, and the condition of the spawning runs at those historical streams and rivers that have produced previous annual quotas.
