I had the same question in regards to Baptiste. I was in contact with a head CO, and what he told me is that the tag's are good until March 31 2013. Algae blooms fall to the bottom of the lake and absorb into the setiment. He said they are only temporary and the fish will be good to eat eventually. If they do deem the fish unsafe for consumption for the whole season, a refund could be potentially issued. Basically don't eat any fish if there is an advisory in effect. Once the advisory has been lifted you are safe to eat the fish.
I know myself that I will not purchase any tags next year on susceptible lakes to blue green algae blooms or lakes such as Lac La Nonne that have consumption advisories due to high mercury levels.
