when I think of sustainable harvesting, I dont think of MAC or any other organization, I think of "sustainable harvesting" its nice when you know the persons you are getting your livestock from and how they collect said livestock. I am a big supporter of sustainable harvesting, one of the best methods of sustainable harvesting of fish in my opinion is post larval collection around the reef, and then tank raising the said fish to saleable size, this leaves all the mature breeding stock on the reef, when a species is able to be breed and raised in the aquarium, I think that is the best option, the less we are out on the reefs collecting, the better off the reefs are...
