That's the other side of the coin exactly - however, why should X pay more for a "certified" fish just because that's what's there?
X has to eat too.... why should he be forced to pay more because the fish comes with call letters? Since he's not certified, he's not "supposed" to be able to tout it as such, and not be able to ask more for the fish at retail. Besides, if supplier Q has mandarins for one price, and supplier E has non-certified fish a dollar or two cheaper - if X is ordering from both places that week, he'll probably buy the cheaper ones, since they are not a cyanide caught fish. I'd bet that any wholesaler with a lick of business sense would sell them off however he needed to in order to turn them over if he was in a rush to move them, certified or not. If that meant "demoting" them, so be it. (I am not implying that same said wholesaler would "promote" a non-certified fish to fill a MAC order, that would be harder to do, due to the intense paper trail, but could still be done, but that's another issue to pick holes in, and one we've talked about here before too).
I avoid that problem altogether by not buying mandarins

But that's another post too...
The whole system is riddled with probems, which is my point entirely.
Oh and about those 500 certified mandarins -- according to David Vosseler AND Paul Holthus, that glut situation wouldn't happen because MAC retailers will be placing ORDERS and fish will be collected according to what is ordered, and there will be a "standing order" for certain "bread and butter" fishes that are always in high demand. These standing orders would be based on data provided by the MAC retailers... This was told to me specifically over the phone by David, in our lengthy converstation several months back. Others have brought up the impracticality of this proposed system, and I'll defer to them to pick holes in that, but I asked that very question and if I'm to believe what MAC tells me (insert belly laugh here), then that just wouldn't be the case, to have an extreme surplus of a given species. If that was the case, and somebody (gasp, dare I say it...) MISCALCULATED (*snort!*) then I submit that the fish should be DE-CERTIFIED before being sold to a non-certified retailer - then there would be no notation on the invoice, no possiblity of X scooping up any vanilla, and somebody along the chain would have to eat a price difference if there was one (not sure who - but I'm not on the board at MAC - I'm just a non-certified retailer...). Decertification of the fish BEFORE it leaves the chain would close the door on X to be showing that invoice to his customer and selling MAC without buying the MAC accoutrements.
A DE-CERTIFIED fish would still be perceived of higher value if it was caught according to MAC best practices and stanadrds (*g*) but if purchased by a non-certified retailer, it should not be noted as such on any paperwork once it leaves the MAC chain of custody.
