Since I think this is a very important topic, I guess I'll try to get the discussion going...
I think collecting post-larval fish has tremendous potential...both for reducing the amount of wild collection and benefiting aquaculture. The vast majority of larval fish die in the ocean. If we could take them out and figure out how to raise them from larval stage to marketable size, we'll not only be reducing the amount of juvenile/adult fish being taken from the reef, but learning how to raise larval stages of various species. Since this is usually the most difficult step in aquaculture, research in this area could really help aquaculture facilities who are able to breed certain fish, but can't raise them up. Personally, I think it's a great idea and am definitely willing to support this type of collection.
