If you go to the department's website and you look up spawn-on-kelp, you'll see there's a spawn-on-kelp marketing study. Numerous studies have been on this website for a number of years. I'll refer to 2006; they issued roe-on-kelp quota even though it says right on their website that they shouldn't be doing that.
On June 8th, 2006. See this statement in context.
