I am disinclined to eat either sharks or billfish. Being top predators, their rate of reproduction is very low and the international fishery is too intense. That being said, they certainly are good tasting. Here in Calif, the cognoscenti are fully aware of the culinary delights of both the shovelnose and the leopard sharks. Neither of these figures into any particular commercial fishery to a large extent and so I would eat either of them with a reasonably clear concience. Thresher I will continue to avoid until more is known of the sustainability of the fishery.
