Here's a link to the North Coast proposal - the one where the BRTF took the stakeholder proposal (2XA) that best met the stated objectives according to the BRTF instructions, and added more protection - that shows roughly 50
% of the rockfish habitat (hard substrate) and essentially all of the important coastal headlands, except the Duxbury head where the fisherman made their stand, within closed areas.

In the Central region, despite a very fishing-restrictive final proposal from the BRTF, the F&G Commission made up their own even more restrictive proposal, in contravention of the agreed process, after the Governor twisted their arms in the fall of the 2006 election year - why would he have done that? The RLFF (anti-fishing money) has spent $18M directly funding the MLPA process - how effective is that lobby money do you suppose? - and the many environmental groups supporting extreme closures continue to be powerful lobbying interests. How much have the rec fishermen put in? Big commercial interests (the kinds with lobby money) aren't much affected by the coastal no-fishing zones, at least in NorCal (I wouldn't be surprised if the push-back by fishing interests is stronger in SoCal than it was in the previous two regions - there's more commercial and big money hobby fishermen than up here). This is an assault on rec fishermen mostly.
Fish are an important - and readily renewable - source of essential protein. Seemingly ideal from a resource management point of view, and better than the alternatives now heavily relied upon. I don't know anyone who doesn't fish for the food it provides - codyjp, why did you abuse those trout if you weren't going to eat them? Would you rather see demand shift to the products of the less-selective mass fishing industries? That nativist dream of returning to the abundance of hundreds of years and billions of humans ago is not constructive in the current era - though the emotional appeal is undeniable. Fish stocks are going to be down, and in many cases will far farther - we're eating them and there are more of us every year - the question is how best to sustain maximum yield. Or is it how best to make a (...n even) big(ger) aquarium?
The hypothesis that MPAs provide sanctuary for otherwise vulnerable large fish that represent uniquely valuable breeding stock is compelling, and the point of the MLPA legislation was to test this out in a controlled scheme. It has since become a private-funding-driven vehicle for closing as much of the coastline as the political process can achieve, and the controlling interests are on record stating they don't care whether the testing part is funded or not, they want closures.
If you think that ecosystem integrity is important, why would you favor closing such a high proportion of habitat, concentrating effort in the remaining open marginal habitat? Isn't that likely to create more damage than just dialing back disseminated fishing pressure through use of seasons, bag limits, and size restrictions? Harvest or clear-cut?
