Yes, I know. I'm going to be very quick.
With regard to the biomass projections, we've had a wonderful set of scientists. It started when we brought the trawl survey over in 1996-1997 with Mikio Moriyasu and the gulf-based snow crab assessment unit. In about 2002 or 2003 the Scotia-Fundy region took over its own science assessment with Dr. Jae Choi, a brilliant scientist, and we've had a spectacular relationship. I myself have a master's degree in science, and we have a great ability to communicate effectively.
We had the built-up biomass that came in the early 2000s and started to fish it. Unfortunately, for some particular reason, we lost all forms of recruitment. The female population disappeared. Everything looked bleak. In 2005 it looked very bleak, and we continued to take rapid serious cuts because that was the recommendation.
What ended up happening was that in about 2007 it attenuated on the bottom end, and then we've seen recruitment pulses start to come. There was a little blip, and it's grown. There is a series of histograms, and the picture would speak 1,000 words, but it has grown significantly.
Through that period of time, the 61 licences that were created in 2005 have all shared equally in the growth. Last year there was a 31% increase in the TAC. This year there is another 22% increase. The new corporate participants received a 31% increase last year and a 22% increase this year. They're over 50% above where they were just a few years ago, as all of us are, because it's been shared equally among us.
The prognosis for the future is that we still have recruitment pulses or waves coming in. The fishery looks very bright for the next two or three years. Then we are likely to experience some form of decline, as with all fisheries.
The increase that we're experiencing right now has occurred significantly more rapidly than what the scientists would have predicted. In 2005 there was no vision of any rebound at all, but it seems that the serious and significant cuts that we took have led to a more rapid rebound, and we're actually at the point now of having quite a bit of recruitment as well as fishing the resource. Last year, for example, the fishable biomass rose 45%. We took a 22% increase because there are reasons to be cautious still, but there was a 45% increase in our fishable biomass estimates from 2009 to 2010, which is huge. Again, a lot of that is attributed to the kind of cuts we have made. That is where we say we try to make the right decisions, because we interact with the science and respond to it.
I don't want to talk too much about what was discussed in the previous group, but the permanent fleet and the aboriginal fleet fully funded the trawl survey before the corporate licence holders came, and they will continue to pick up the slack. It will be funded 100%, regardless of whether they pay or they don't. It was crucially important to get them here, and it is still crucially important, so we have funded the survey for the last three years. They haven't fully paid in any one of those years, but it has just gotten worse.
That was the biomass issue.
I'm sorry; what was your formula question?
