Thanks for that question. Those fisheries, especially bottom trawling, that damage habitat structures like coral sponges or other three-dimensional habitat that are especially important for juveniles are known to affect biodiversity more than other fisheries. One of the things we do know is that there are a lot of linkages, even in the water column, for ecosystems. So even if a lot of fishing still happens that doesn't affect the bottom, it can still have an effect on the ecosystem as a whole. Things are connected. Things at the bottom rely on some of those interconnections.
I think it's certainly possible to have some effective protection by still allowing aspects of fishery to happen that don't damage some of that habitat, but we do also need some places that show us what the impact of fishing and other extraction is by having some baselines where we don't do fishing, just to see what the impact actually is.
