12 fish you should NEVER eat
Gammy Dodger stashed this in Things that shouldn't get eaten
Yes fish, no fish, red fish…OK fish? Our oceans have become so depleted of wild fish stocks, and so polluted with industrial contaminants, that trying to figure out the fish that are both safe and sustainable can make your head spin. "Good fish" lists can change year after year, because stocks rebound or get depleted every few years, but there are some fish that, no matter what, you can always decline. The nonprofit Food and Water Watch looked at all the varieties of fish out there, how they were harvested, how certain species are farmed, and levels of toxic contaminants like mercury or PCBs in the fish, as well as how heavily local fishermen relied upon fisheries for their economic survival. These are the 12 fish, they determined, that all of us should avoid, no matter what.
Imported Catfish - Vietnamese would be full of antiboitics
Caviar - species under threat
Atlantic Cod - over-fished
American Eel - full of PCBs
Imported Shrimp - full of chemicals
Atlantic Flatfish - contaminated
Atlantic Salmon (both wild-caught and farmed) - wild is under pressure, farmed would be highly dosed up
Imported King Crab - Russian fisheries have no enforced limits
Shark - high mercury content
Orange Roughy - high mercury content an over-fished
Atlantic Bluefin Tuna - critically endangered and full of mercury
Chilean Sea Bass - massively over-fished, almost extinct
I've heard that Chilean Sea Bass goes by other monikers:
The Latin name for Patagonian toothfish is Dissostichus eleginoides. It is sold under the trade names Chilean sea bass in the USA;Merluza negra in Argentina, Peru and Uruguay; Legine australe in France; Mero, in Japan and Bacalao de profundidad in Chile.
The name "Chilean sea bass" was invented by a fish wholesaler named Lee Lantz in 1977. He was looking for a name that would make it attractive to the American market. He considered "Pacific sea bass" and "South American sea bass" before settling on "Chilean sea bass".  In 1994, the U.S. Food and Drug Administration (FDA) accepted "Chilean sea bass" as an "alternative market name" for Patagonian toothfish.
In the UK, the approved commercial designations for D. eleginoides and D. mawsoni are 'icefish' and 'toothfish'. This has created some confusion as there is a genuine 'icefish' (Champsocephalus gunnari) caught in subantarctic waters, which does not resemble toothfish in any way.
I guess we've done it before, you know the story of the passenger pigeon:
The Passenger Pigeon, once probably the most numerous bird on the planet, made its home in the billion or so acres of primary forest that once covered North America east of the Rocky Mountains. Their flocks, a mile wide and up to 300 miles long, were so dense that they darkened the sky for hours and days as the flock passed overhead. Population estimates from the 19th century ranged from 1 billion to close to 4 billion individuals. Total populations may have reached 5 billion individuals and comprised up to 40% of the total number of birds in North America (Schorger 1995). This may be the only species for which the exact time of extinction is known.
The Passenger Pigeon is now extinct. Over hunting, the clearing of forests to make way for agriculture, and perhaps other factors doomed the species. The decline was well under way by the 1850’s.
The last nesting birds were reported in the Great Lakes region in the 1890’s. The last reported individuals in the wild were shot at Babcock, Wisconsin in 1899, and in Pike County, Ohio on March 24, 1900. Some individuals, however, remained in captivity.
The last Passenger Pigeon, named Martha, died alone at the Cincinnati Zoo at about 1:00 pm on September 1, 1914. Who could have dreamed that within a few decades, the once most numerous bird on Earth would be forever gone?
