The TACs are based on the best available science, not on the exploitation levels. The assessments are done periodically, in either five-year or longer intervals. In some cases, yes, these are long-lived species. Most groundfish, as Natalie referred to with yelloweye rockfish, live over 100 years. Many of the species live to 40 or 50 years of age, and some of them don't become reproductive until their teens. So it takes 20 or 30 years to see the impacts. In fact, with rockfish, the science believes that you might get a strong year class once every 25 years.
It takes extended periods of time to see those increases in productivity, but in some cases we have. We have been managing these systems in a similar way for approximately the last 20 years, and in many of the cases we are seeing increases in abundance. In part, we don't know if it's strictly because of under-harvesting or if it's because of good environmental conditions for reproductivity and strong year classes, but there have been some signs of increases.
