...farmed salmon--an exchange that depletes the world supply of protein. The diet of farmed salmon lacks the small, pink-colored krill that their wild cousins eat, so the flesh of farmed fish is gray; a synthetic version of astaxanthin, a naturally occurring pigment, is added to the feed...
...fish farming at its worst, travel to Chile, where salmon farming has boomed in the past decade and generates $1 billion a year in export revenue. "A film of feed leftover made of fish oil, animal fat and transgenic soybean oil floats on the water around the salmon farms," says Ronald Pfeil, 67, a cattle farmer in Chile's remote Aysen region. "When the tide is low, the beaches stink...
Experts say aquaculture done right could easily feed the world without polluting it. A favored method of environmentalists is the hard-walled pen system that isolates the fish from the surrounding water in 40-ft.-deep tanks and catches their waste in the bottom. Even more secure are containment ponds built onshore into which seawater is pumped. Agrimarine Industries in Cedar, B.C., is testing a site with eight tanks 100 yds. from the sea and 40 ft. above it. But production costs are expected to be about $2.20 a fish--double what it costs to raise a salmon...
...Chinese, who have been farming fish for 2,000 years, pioneered a method in which nothing is wasted. Farmers dig ponds around rice paddies and feed carp in the ponds with weeds from the rice field. The silt from the ponds is used as fertilizer for the fields, and crabs are grown to eat pests. Some of those techniques are being adapted in Western fish farms. In Tuscaloosa, Ala., Dan Butterfield, 59, raises bass, carp, catfish and other species in the same pond; the sun and the catfish feces stimulate the growth of phytoplankton, which feeds the other species...
...that the corpse had more charisma than Von Hagens; a little more sensationalism would have been welcome. But while Von Hagens might not be the ideal person to resurrect the public autopsy in all its histrionic glory, his performance was a reminder of how the practice helped feed one of Europe's greatest periods of intellectual fervor. Even though we were there to record the scandalized reactions of the crowd, many journalists spent the night craning to look at parts of ourselves that we had only pictured before in an abstract way. Is my liver really that...
