When Captain John Smith explored the Chesapeake Bay in 1608, he wrote that the oysters "lay as thick as stones." But hundreds of years of harvesting every oyster in sight have brought the bivalve population in the bay to record lows. Fewer oysters means murkier water, as a single oyster can filter 50 to 60 gallons a day. Dredge harvesting didn’t help either, as scooping up wild oysters flattens the bottom and ruins their habitat.

Cousins Ryan and Travis Croxton of Rappahannock River Oysters are trying to turn the tide. Their great-grandfather founded the company in 1899 when he leased five acres of river bottom on the Rappahannock River near Bowlers Wharf, VA. Their grandfather advised their father not to get into the family business, as it’s a lot of hard work with uncertain return; Hurricane Hazel wiped out their entire season’s efforts in 1954.

Aquaculture – hurrah (in many cases). Sustainable seafood – calloo callay.

Generally speaking, we're on the side of anything that's proven to feed people healthily and not further deplete the Earth's resources. We'll also just note that it would be in the best interest of sea cucumbers' marketing strategists to minimize the ishfay ooppay onsumptioncay chatter and any manner of portraiture until the eaters of the world have found them to be as delicious and indispensable as chicken nuggets.

Starts around 3:50 in the video and yes, we've eaten and are fans(ish), but might have opted for a nice green salad or a rumbling stomach had we first seen it in its living state.

In Hong Kong, where factory space is stacked in skyscrapers, the 15th floor of an industrial block houses vast tanks in which thousands of rare fish swim under the eerie, purple glow of UV lights.

Normally found thousands of miles away on the reefs of the tropics, the coral grouper are being bred on land in one of the world's most densely populated metropolises to feed a local population that consumes 3.6 times the global average in seafood.

Sold live, fish like leopard coral grouper are highly valued in China, where ostentatious dining calls for expensive and attractive centerpieces for celebratory or business banquets - last week during the Lunar new Year a single fish could cost around $130.

But even the tons of fish swimming in the tanks of OceanEthix incongruous high rise facility can't sate a growing market for live reef fish in Hong Kong and mainland China that is worth around $1 billion each year.
