The Beacon: Andy Sharpless's blog
President Bush deserves congratulations for his announcement yesterday of protections for an area of the American Pacific equal in size to Spain. Setting this area off limits to fishing and to oil and mineral exploitation is a vivid example of how a country can use its national laws to ensure the long-term abundance of huge areas of the sea. We also congratulate the conservation organizations that worked hard for this result, especially The Pew Environment Group (which also helped found Oceana).
This burst of ocean news follows a terrific in-depth report in this week’s issue of The Economist. We thought you would be interested in reading it. At sixteen pages, Troubled Waters delivers plenty of information on the unfolding collapse of marine environments: fishery mismanagement, ocean acidification, dead zones, and poorly managed aquaculture.
President Bush deserves praise from ocean lovers for his creation of three new marine national monuments in the Pacific Ocean. This action protects some of the few remaining pristine coral reefs in the world by prohibiting all forms of commercial fishing and severely restricting recreational fishing.
These are among the last places on the planet where you can still see sharks and other top predators in something like a healthy state. President Bush – and the Pew Environment Group, Marine Conservation Biology Institute and Environmental Defense Fund, who worked so hard for these monuments – can be justifiably proud of the results.
It’s easy to point out that the protected areas around the 10 islands could have been 16 times larger if Bush had included the full 200 mile exclusive economic zone in the monuments.
President-elect Barack Obama’s appointment of Jane Lubchenco, an Oregon State University marine biologist, to head the National Oceanic and Atmospheric Administration could be a major, positive step for protecting America’s fisheries.
In recent years, NOAA has, too often, ignored scientists’ advice when it comes to setting quotas for some of our most vulnerable fish species, favoring commercial interests over conservation. With a scientist like Lubchenco in charge, I hope that NOAA will start to take a more scientific tack in its management.
Lubchenco, a well-regarded researcher and professor, will have her hands full. America’s fisheries are among the best-managed in the world, but that’s just because there’s not much competition.
I’m not sure what the marine equivalent of a bandwagon is (a love boat?), but there’s one headed our way. I’m talking about the movement called “individual fishing quotas,” as described in a recent LA Times article. The original theory is straight out of the free market school of economics: give people the ownership of something, and they’ll be good stewards. As I’ve written before, this isn’t necessarily so.
Indeed, as the article points out, such programs can’t work unless there are restrictions on overall catches. And they also can’t work unless there are mechanisms to limit and reduce bycatch and discards of other species, including coverage by scientific observers. And they can’t neglect dealing with fishing gear impacts on bottom habitat.

">Stocking the Cabinet,” Grist speculated on Barack Obama’s potential nominees for the “top environmental jobs” in his administration.
For the oceans, however, the most pertinent post isn’t the head of the EPA, or the secretary of agriculture, energy or interior, all of which were included in Grist’s guessing game. Guess what is?
Hint: The position is currently filled by a man who made his fortune selling Froot Loops and Frosted Flakes.
The International Maritime Organization’s recent decision to adopt tighter emission rules for the global shipping fleet is a step in the right direction in an industry where emissions have been practically unregulated. Ship emissions are blamed for 60,000 deaths worldwide each year – a sincere public health threat.
The new rules, however, only address sulfur and nitrogen oxide emissions. Meanwhile, carbon dioxide emissions from the same ships remain a major, and often overlooked, contributor to global warming.
The world’s shipping fleet comprises 300,000 ships, each a city block in length, and transports 90 percent of the world’s trade. In 2007, the fleet emitted nearly twice as much carbon dioxide as all of America’s cars combined. If the fleet were a country, it’d be ranked as the sixth largest producer of CO2, between Japan and Germany.
Not to mention that these ships use the dirtiest fuel available, creating a high percentage of unusable sludge that must be burned.
The financial collapse of the past few weeks offers striking parallels to the collapse of ocean wildlife. How is what’s happening on Wall Street and in financial capitals around the world like what’s happening in our seas?
Lehman Brothers and Canadian cod aren’t coming back.
The word “collapse” appears in nearly every thoughtful report on the financial crisis, and it’s also a common metaphor in the scientific reports on fishery depletion. It’s accurate in both cases because thelly notion that you can borrow more than you can afford, or spend more than you earn, inevitably produces a sudden and abrupt change when the money runs out.
In the fishery context, the notion that you can catch and kill very high levels of wild fish each year naturally leads to an empty ocean. For example, bluefin tuna fishing companies in the USA have not been able to catch their quota in the Atlantic. There just aren’t enough tuna to be found out there. By contrast, in personal financial terms, if you live off the interest and dividends on your investments, you can sustain that forever. But if you spend down your principal, you are on a path to going broke. The cod fishery off the eastern coast of Canada has never come back. Lehman Brothers isn’t coming back either.
A new study in this week’s Science finds that the two distinct Atlantic bluefin tuna populations – those spawned in the Gulf of Mexico and those spawned in the Mediterranean Sea – meet during their juvenile years in the Atlantic before returning to their respective natal homes to reproduce.
In addition to being fascinating (the authors studied isotopes found in juvenile tuna ear bones used for balance, called otoliths, as they contain chemical markers delineating water composition), the study underscored a very important point about bluefin tuna conservation.
While there are two distinct spawning grounds, the tuna intermingle – meaning that U.S. fisheries may actually be catching eastern, Mediterranean tuna, and vice versa.
Why does this matter?
It’s been said over and over again: Eastern bluefin tuna cannot handle the pressure they face from overfishing. These sleek and powerful fish are unlucky enough to be among the world’s most coveted seafood species, and for years scientists have called for a moratorium as a last-ditch effort to save these genetically pure, irreplaceable creatures. While strict quotas have been in place for years, poor quota enforcement and illegal fishing have driven the bluefin to the brink of extinction.
On Monday, the European Union ended the fishing season for most of the Mediterranean’s purse seine fleet, the ships that are responsible for 70 percent of the Med’s caught tuna. This move could save up to 100,000 bluefin this year alone.
Oceana has been carefully monitoring the purse seine fleet with our new boat, the MarViva Med. We have recorded rarely-seen images of bluefin fattening pens and documented purse seiners illegally using spotter planes in their pursuit of the fish.
I didn’t anticipate that the E.U. would react so quickly and shut down the season well before its original July 1 end date. But our work is far from over. The next step is to make sure that the closure is enforced, and that non-E.U. fishing outfits don’t start targeting tuna as well. We will be watching.
This week in ocean news,
...fishery managers voted to cancel the chinook salmon fishing season off the coast of California and most of Oregon in light of the fish population's rapid collapse. The commercial fishery is worth an estimated $30 million....
...many fishermen considered supporting the ban on West Coast salmon fishing in light of this year's record low catch. "There's likely no fish, so what are you going to be fishing for?" said one....
...while some other fishermen went ahead with a pre-season barbeque, although it was less well attended than in past years...
