When the sharknado takes Manhattan, we'll see the numbers more even.

100 million sharks are killed every year because of finning.

Yeah, that seems like hyperbole.

It's obvious to me the author never had shark fin soup.

Yummy!

Do you think if during the day someone asks them, "What do you do for a living, " that this person would claim journalist as their title?

That works out to each person in China eating one shark fin every 13.4 years.  Not so hard to believe, even if you ignore the other countries where this dish is served.

It's suprisingly close. This paper (PDF) says it could range anywhere from 63 to 273 million sharks (unless I'm reading it wrong, I'm not too specialized in shark mortality rates).

Based on an analysis of average shark weights, this translates into a total annual mortality estimate of about 100 million sharks in 2000, and about 97 million sharks in 2010, with a total range of possible values between 63 and 273 million sharks per year.

Oh, so mother nature needs a favor? Well, maybe she should have thought of that when she was besetting us with droughts and floods and poison monkeys.

Anyone else notice how, when animals are being hunted to extinction or endangered animals are being eaten, that the Chinese are always somehow involved?

omelete: Oh, so mother nature needs a favor? Well, maybe she should have thought of that when she was besetting us with droughts and floods and poison monkeys.


Yeah, nature started this fight for survival and now she's losing she wants to quit! Well I say hard cheese!

On a more serious note, I don't know why but whaling, sharkfinning (I just learned that was the term), and general overfishing of the sea really bothers me. More than the conditions of cows in abattoirs, I don't know why. Maybe it's because I love sea food, I want it to stay there forever. I'd give up tuna for a year or two if I thought it might help, but it won't, because no one else would, so I keep eating it. I wonder what one person can do. About the only thing I'll do is eat dolphin friendly tuna, which I try not to think about too much, because I'm sure it's a marketing lie.

I'm not a marine biologist, but what stood out to me was their use of 20 kg as an average weight for a shark that's caught and finned/killed. Are we really finning 50 pound sharks? That's a shark the size of my dog...

I'm not saying it's not true by any means, but does any one have more insight on how shark fishing is actually accomplished? In my mind an animal would have to be like half a ton before it would be profitable to harvest...

In finning, all that's kept are the fins, the rest is chucked back overboard...usually still alive. So, hook shark, land it, cut off fins, chuck back overboard.

It's the weight of the fins, not the full weight of the shark. So they're taking 20kg in fins from the sharks.

Shark meat is pretty tasty... Why waste so much?

That doesn't seem to be what the article says?

Using the average shark weights givenin Table 2, these masses
were converted into numbers of sharks. Using the median estimate of
20.8 kg for all sharks (Table 2), it was here calculated that the total
mortality of 1,445,000t translates into 69,471,000 shark individuals. 

Maybe I'm just not accustomed to reading this type of paper. If they're saying 1,445,000 tons of shark fin is traded each year, and each shark fin weights 20.8 kg, I understand their number. But they seem to say 1,445,000 ton of shark is traded each year (well, actually, their graph says this is reported in units of 1,000 tons, but the in line text doesn't seem to consider this when explaining the calculation).

It's actually a fairly confusing whitepaper.

Because if you have room for 100 pounds of stuff, and you can either bring home 100 pounds of stuff that sells for $50/pound or 10 pounds of stuff that sells for $50/pound and 90 pound of stuff that sells for $5/pound, you're filling your boat with the $50/pound stuff.

Ah wait, they just meant rounding, not reporting. So I get that. I'm just not clear on if they're comparing total tonnage of shark caught or total tonnage of shark fin taken.

It really seems like they're saying the average shark is 20.8 kg. I'm not neccessarily disputing that, but it seems like nurse sharks/bull sharks/etc. are like 10x that, even considering female sharks and not-yet-adult sharks?

So all we have to do is make shark meat worth $55/lbs and they won't be able to bring as much home, so fewer sharks will be definned? Or will they just get an old supertanker and use that to fish with?

Imagine that as a solution, globally artificially setting the price of shark meat. It'd create a bustling black market, i'm sure, and make millions of new fishermen.

Probably because cows are bred and farmed to be food in a (mostly) sustainable manner.  There really is much in the way of large-scale fish-breeding (in the wild), at least not that I'm aware of.
