We set the tax in consultation with the industry, the provinces, first nations, and obviously in consideration of scientific advice. The difference between the previous years and this year is that the scientific advice was really, really clear, plus the fact that we had done work on the precautionary approach leading up to this year. So this year we have had additional information regarding what is an acceptable harvestable biomass and what are the risks of going below that. That additional information made it clear that we are at the bottom of the cycle of abundance, that we had to take action to minimize the time we're going to stay at this level and to maximize the probability of climbing out of it. That's what the decision was based on this year.
The risks in the past few years were less clear or less significant, and we could keep the catch at a higher level. This year required significant corrective action in order to minimize the amount of time we stay at the bottom of the cycle of abundance.
