The biggest impact to fishing will probably be that we've fished out most of the worthwhile wild food species. I would put my money on any significant growth occurring in fish farming, or things like lobstering, where we are effectively farming. Regulations limiting catches and seasons to try to preserve the fisheries in some state of production have already driven many people out of fishing.
