California Science Center: Kelp Harvesting
Dec 31st, 2010 by Michael Bear

Date: 12-30-10

Location: Palos Verdes

Time: 10:15 am

Dive Length: 35 mins

Swells: 8 footers, with the occasional 9 footer, and white caps as far as the eye could see

Viz: absolute zero–no joke: Iraqi-sandstorm-can’t-see-your-hand-in-front-of-your-face-zero-viz

Mix: 32%

Dive Buddy: NOAA Jim

Dive Boat: California Science Center Boat: Maximus

Highlights:

Despite generally poor conditions up and down the coast of Southern California recently, Los Angeles Science Center divers got the call Monday to show up this week for some kelp harvesting for the Ecosystem Kelp Exhibit, so NOAA Jim and I headed up to San Pedro to meet up with the Center boat Maximus.

On the way out to the dive site in Palos Verdes, we flew over some pretty decent 8 ft swells, with white caps everywhere, so we were under no illusion as to the conditions we’d be diving in–and sure enough, when we dropped anchor, even in the protected area of the dive site, visibility was absolute zero. You literally could not see your hand in front of your face.

We had to grope our way, hand-over-hand, to fronds of macrocystis in the swirling, underwater ‘sandstorm’ and harvest them by feel: the assignment was to get 15-20 footers, with the holdfasts, so they could be reattached to rocks in the Ecosystems Kelp Exhibit.

Once you got the feel for it [ha, ha!], it actually wasn’t too hard–but, it was tricky in the zero viz, because it always seemed that a neighboring kelp frond, as if in retaliation for harvesting his ‘buddy,’ would try and wrap itself around your leg, foot, or tank valve, so you’d have to untangle yourself from ‘him’ first, before being able to make your way back to the surface with the 15-20 footer you had just harvested.

But, eventually, we got what we had come for and had to make our way back to San Pedro, for a date with the dock crane, which apparently, was only available until noon that day. If you stop and think about it, which I hadn’t–it requires a crane to return a large container of sea water and harvested kelp fronds to the dock.

See below for some rather jerky video I took on the way out–blame the swells for that–as well as video I took of our DSO, Chris Wade, guiding the crane over the kelp container, in order to lift it onto a truck for transport back to the Science Center.

‘nuther day in Paradise, folks!

Study: Drifting Fish Larvae Allow Marine Reserves To Rebuild Fisheries
Dec 29th, 2010 by Michael Bear

CORVALLIS, Oregon — Marine ecologists at Oregon State University have shown for the first time that tiny fish larvae can drift with ocean currents and “re-seed” fish stocks significant distances away – more than 100 miles in a new study from Hawaii.
The findings add credibility to what scientists have believed for some time, but until now been unable to directly document. The study also provides a significant demonstration of the ability of marine reserves to rebuild fishery stocks in areas outside the reserves.
The research was published this week in PLoS One, a scientific journal

Study Shows Marine Reserves Send Fish Far and Wide
Dec 23rd, 2010 by Michael Bear

Scientists now have hard evidence for something they have long believed _ that establishing no-fishing zones in the ocean will help replenish fish populations far away that have been over-harvested.

Authors of the study published online Wednesday in the peer-reviewed journal PLoS ONE said it bolsters scientific evidence for establishing marine reserves in coastal waters, which have faced stiff opposition from the fishing industry.

Lead author Mark Christie of Oregon State University said they used DNA sampling on 1,073 yellow tang, a popular aquarium fish, off the Kona Coast of Hawaii in 2006 and found their offspring were as far as 114 miles away. Two fish in unprotected areas were genetically linked to parents inside protected areas.

Michelin Guidebooks: Defiance and Conciliation on Shark Fin Soup Issue
Dec 23rd, 2010 by Michael Bear

I received this today from Michelin Guidebooks, regarding an earlier email I had sent them about their habit of giving 3 Star ratings to restaurants in Hong Kong which serve shark fin soup.

Their reply is an interesting mixture of defiance and conciliation. They claim that they are not rating the

shark fin soup *per se,* but the overall ambiance and menu and that they are not encouraging the serving of

shark fin soup by doing so.

I beg to differ. I would maintain that getting a 3 Star rating from the world-renown Michelin Guidebook does *indeed*

encourage whatever you happen to be doing at the time. So sought after is their rating system among chefs, that a couple years ago, a chef in France committed suicide because  Michelin downgraded his restaurant by *one* star.

See what you think:

*******************************************************************

Dear Mr Bear,

Thank you for your correspondence relating to the subject of shark fin.

We would like to assure you that we appreciate your concerns and fully recognise that shark fin soup is one of the restaurant industry’s most controversial and challenging dilemmas.

While it is true that shark fin soup is available in restaurants that are recommended in our guide, it is also worth noting that it is a dish served in nearly all Cantonese restaurants. Demand for shark fin soup remains strong throughout China and its cultural significance cannot be ignored. It appears that public opinion in Hong Kong is unlikely to change until there are international agreements at government level concerning the harvest and sale of shark fin.

We do, however, share your concerns. We want to assure you that we do nothing to promote or encourage the consumption of shark fin. Indeed, you will find that in the 2011 Hong Kong Macau Michelin guide there is no mention whatsoever of shark fin soup anywhere in the guide, nor are there any photographs of shark fin dishes. This is no coincidence, as we have actively sought, through our texts, to direct our readers towards other specialities available in Cantonese restaurants.

In the meantime, we would like to thank you for your comments and for your interest in our guide.

Yours sincerely,

The Michelin Guide team

Shark Conservation Bill Headed to Obama
Dec 21st, 2010 by Michael Bear

The House adopted legislation Tuesday aimed at protecting sharks off U.S. coasts, though an exemption in the bill has raised concerns among federal fishery officials.
The Senate approved the bill Monday, and it now awaits President Obama’s signature.
The Shark Conservation Act addresses loopholes in a law passed a decade ago in an effort to curb “finning,” the practice of cutting off a shark’s valuable fins and dumping its body overboard. It would require any vessel to land sharks with their fins attached and would prevent non-fishing vessels from transporting fins without their carcasses.
Shark finning, now prohibited off the Atlantic Coast and the Gulf of Mexico but not the Pacific, has expanded worldwide due to rising demand for shark fin soup in Asia.
To win the support of Sen. Richard Burr (R-N.C.), the bill allows those catching smooth dogfish off his state’s coast to bring in fins separately, as long as they account for no more than 12 percent of the total weight of the catch.
