"Adjusting for time of year, and after checking and measuring 1,275 different trophy fish, she found that in the 1950s, the biggest fish in the photos were typically over 6 feet — sometimes 6 feet 5 inches long. By the time we get to 2007, when Loren bought a ticket on a deep sea day cruise and snapped this picture ...... the biggest fish were averaging only a foot, or maybe a little over. That's a staggering change. The biggest fish on display in 2007 was a shark, and sharks, Loren calculated, are now half the size they used to be in the '50s. As to weight, she figured the average prizewinner dropped from nearly 43.8 pounds to a measly 5 pounds — an 88 percent drop. Radiolab reports on how the average trophy fish caught at Florida's Key West has shrunk considerably since the fifties

If I offered evidence that jellyfish are displacing penguins in Antarctica—not someday, but now, today—what would you think? If I suggested that jellyfish could crash the world’s fisheries, outcompete the tuna and swordfish, and starve the whales to extinction, would you believe me?
The New York Review of Books reads
Lisa-ann Gershwin's book about the rise of the jellyfish and the coming "jellification" of our oceans. (Previously but not as terrifyingly
.) [more inside]

"The world’s oceans have been experiencing enormous blooms of jellyfish
, apparently caused by overfishing, declining water quality, and rising sea temperatures. Now, scientists are trying to determine if these outbreaks could represent a “new normal” in which jellyfish increasingly supplant fish.. Total jelly domination would be like turning back the clock to the Precambrian world, more than 550 million years ago."

Altered Oceans: A Primeval Tide of Toxins The fireweed began each spring as tufts of hairy growth and spread across the seafloor fast enough to cover a football field in an hour. When fishermen touched it, their skin broke out in searing welts. Their lips blistered and peeled. Their eyes burned and swelled shut. Water that splashed from their nets spread the inflammation to their legs and torsos.

The Starving Ocean
: A large collection of articles by Debbie MacKenzie on the death of the ocean. The idea is that removing most of the fish from the sea might be sort of bad for the marine ecosystem as a whole. Her writing style is a bit kooky, but she has been right on some points (ie. the Grey Seal thing). Oh, and fishing is also responsible for the rise of atmospheric carbon dioxide

Coral Reefs Doomed
Well, overfishing has destroyed the Grand Banks
and now according to studies, it is "dooming" the coral reefs as well. When will learn? That being said, can anyone actually see the world's governments agreeing on doing anything to stop it?
