What’s Killing California’s Sea Otters?

September 17, 2010September 20, 2010 Andrew Thaler 8 Comments

Sea Otters are turning up dead in central California. In 2007, 11 sea otters were recovered from Monterrey Bay. Over the last three years, dead otters washing up on beaches has reached a record high?

What could be causing all these otter deaths? Are there new predators in the area? Is there some kind of disease? Could increased otter deaths reflect an increase in otter populations, indicating not otter population decline, but otter population growth? The answer turns out to be even more surprising – freshwater algae.

Innovative Conservation: Shark Attack Survivors Speak About Saving Sharks

September 15, 2010 David Shiffman

Conservation, Science

Last Monday, the Pew Environment Group’s Global Shark Conservation Campaign arranged for a brilliant PR stunt – they arranged for survivors of shark attacks to speak about shark conservation outside of the United Nations headquarters in New York. Though very few people are ever bitten by sharks, many fear them, which makes it difficult to … Read More “Innovative Conservation: Shark Attack Survivors Speak About Saving Sharks” »

Our favorite sea monsters – The Giant Manta Special Edition

Conservation, Science

Sea Monsters, mythical beasts of legend and lore that ply the world’s oceans, sinking ships, terrifying sailors, swallowing entire crews whole. Sea monsters occupy a special place in our imagination. The ocean is huge, unfathomable. Of course mighty beast could dwell within, undetected.

Every once in a long while, the myths, the legends, the stories, turn out to be true. This is one of those times.

Greenwashing – Is there really a sustainable Orange Roughy fishery?

September 6, 2010September 13, 2010 Andrew Thaler 9 Comments

Conservation, Science

Wandering through the grocery store the other day, I noticed something strange in the fish bin. Now, in general I’m pretty conscious of where my fish comes from, how it was caught, whether the fishery as a whole or the specific population is sustainable. I pay attention to those details and I can usually tell when a company’s branding is legitimate and when it’s just greenwashing.

Imagine my shock when I found a packet of Orange Roughy, sold by the Full Circle brand, and marketed as sustainable.

Shark Conservation: The problem, the goal, and how to get there

The problem

Sharks consistently rank near the top of lists of American’s greatest fears. In reality, they have much more to fear from us than we do from them. Because of our actions, many species of sharks are on the verge of extinction. A recent International Union for the Conservation of Nature Shark Specialist Group report shows that fully 1/3 of open-ocean species of sharks are in danger of extinction in the next few decades. Many shark species have had population declines of over 90% in the last few decades.

Interridge code of conduct for resposible research at hydrothermal vents

Conservation, Science

The following is a repost from the old Southern Fried Science WordPress blog. The original can be found here.

bluebreeze-fixed_logo InterRidge, a global organization of hydrothermal vent biologists, has, over the last several years, established a set of guidelines for responsible research practices at deep-sea hydrothermal vents. Along with many scientists, several nations and commercial organizations have signed onto this statement. Although tailored to deep-sea science, these guidelines are broadly applicable to any science program that requires field work.

Bottom trawling and the importance of plaice

Conservation, Science

“The commons petition the King, complaining that where in creeks and havens of the sea there used to be plenteous fishing, to the profit of the Kingdom, certain fishermen, for several years past have subtily contrived an instrument called the “wondyrechaun” made in the manner of an oyster dredge, but which is considerably longer, upon which instrument is attached a net so close meshed that no fish, be it ever so small which enters therein can escape, but must stay and be taken.

And that the great and long iron of the wondyrechaun runs so heavily and hardly over the ground when fishing that it destroys the flowers of the land below water there, and also the spat of oysters, mussels and other fish upon which the great fish are accustomed to be fed and nourished. By which instrument in many places, the fishermen take such quantity of small fish that they do not know what to do with them; and that they feed and fat their pigs with them, to the great damage of the commons of the realm and the destruction of the fisheries, and they pray for a remedy.”

Petition by the Commons to King Edward III, 1376 (from The Unnatural History of the Sea)

This petition, penned in 1376, reveals a depth of understanding that we often don’t attribute to 14th century fishermen. Habitat destruction, overfishing, bycatch, even common pool resources are all clearly described here. In it, the Commons protests a new and efficient, though inaccurate fishing tool, the ‘wondyrechaun’, and begs King Edward III to ban it. This is the first historical record of the ‘wondyrechaun’, what today is called a beam trawl. Everything you need to know to understand why the world’s fisheries are in trouble is contained within the single fact that, in 1376, at it’s very inception, the people begged the king to ban it’s use, and 700 years later, the beam trawl survives.
