The problem is that the idea we can over collect as an industry is silly. Th e quotas allowed by CITES has little effect of the protection of the ecosystems ............It is impossible to have any effect when our industry only removes one-billionth of the total rubble rock available .....its only if we collect all the rock from too few locations that we run into any over collection issue. But CITES seems more concern about appearances then actual protections. The controlling the total amount of harvest is pointless! How many total kilos of rock do you think is laying around on the seafloors of the 1200 islands that make up the Country of Fiji? What percentage of that total do you think we as a hobby would remove each year if we could collect as much as we wished? Now times that amount by one thousand times and you would still have less then one billionth of one percent of the total rock available to collect. The amount of product removed is tiny no matter how you slice it .........So the idea that controlling the total amount of material removed will somehow have an effect on the environment is purely for show..... Its not how much you collect ......its how much you collect and from where that effects the reef flats....... Take a look at walts site and how they explain the collection process..... http://www.pacificaquafarms.com/premium.htm That reef flat is just one of thousands in Fiji.....If that one flat is a year of collection as claimed on the site .....then that would mean there is a thousand years of collection availible.
