How can we stop the fishing in this area to protect the birthing of more sharks? Obviously they come here and people are killing them before they have a chance!

@ Kurt

By your logic, we should eradicate all animals that have killed humans, including bears, lions, crocodiles, tigers, etc. Oh, yeah-- and snakes, wasps, hippopotamus, and elephants, too. Let’s throw in jellyfish, while we’re at it. That we should also destroy all domestic dogs goes without saying, since they kill far more than 5 persons “a rear” [sic].

Because your understanding of ecosystems is especially juvenile, you should check out this illustration that shows what happened to Yellowstone when their top predator -- the wolf -- was reintroduced after 70 years:

The effects of losing an apex predator are profound and far-reaching, even over a short period of time, trickling down to flora growth and habitat change. Can you really imagine an ocean without sharks?

Kurt

Who cares about the sharks.... It always shocks me that people care about these fish that kill people from time to time, I don't care if it's 5 times a rear or a thousand, if I can stop 5 deaths by killing sharks, then you are damn right I will do it.

And don't even get me started on the ecosystem needing these fish to continue the balance, trust me it will be fine. Kill them all.... It will make me very happy, so next time I'm south of the boarder I might pay a bounty for any great white fish killed.

The Great White Shark is almost permanently extinct ALREADY; "Thanks alot for your help in doing so permanently you idiot Mexican fishermen with zero brains.....but "You dont care...right....as LONG AS YOU MAKE A QUICK BUCK $$$$......SCREW EVERYONE ELSE AND OUR WHOLE WORLDS OCEAN ECOSYSTEMS WITHOUT NATURES NUMBER ONE APEX PREDITOR, "The Great White Shark".....right???? A quick buck, money in yourr pockets for a few days or few weeks is MORE IMPORTANT.....RIGHT"????!!!!!! The Mexican government MUST learn to tighten up their belts via their police system and coast gaurds and start putting the REAL PREDITORS AWAY....in jail for a LONG TIME to think over long and hard, WHY they feel its much more important to have a few quick bucks in their pockets rather then a proper functioning ocean and ocean ecosystem, so real fishmen can fish properly and within the law to feed their families, since there would then be fish to catch, with a proper, well balanced ocean ecosystem functioning the way its supoposed to, within the laws of nature, so everyone can enjoy the ocean for all the GREAT THINGS the oceans of the world are ENJOYED!!!!!

You’re right. I’ve never seen a great white give birth. Nor have I actually seen a great white, but I do believe they exist. For that matter, I have never seen the Earth as round from space. Nor something as small as an atom. Nonetheless, I am capable of reading intelligent scientific and popular articles written by experts who publish in peer-reviewed journals. And, beyond the fact that the Sea of Cortez is a known habitat for juvenile great whites, many have speculated that the unfortunate 20’ female great white was gravid. For a similar story, see the article following the shark “Amy” (http://www.marinecsi.org/news-events/) and where scientists speculated she gave birth... and where they speculated she met her demise.

Of course, nursery or birthing ground -- or not -- doesn’t change the fact that 13 large great whites have allegedly been hunted in a very short span of time. That’s a call to action, regardless of the semantics we employ in contending where they were born.

@ Matt

If nobody has ever seen a White shark birth, how can you credibly contend that "the Sea of Cortez is a known birthing area for great whites"?

To the contrary, the Sea of Cortez is known habitat for Blue, Minke, Humpback, Fin, Gray and even Sperm whales. These large White sharks are more likely to be in search of whale carrion in the Sea of Cortez than to give birth. White sharks more likely give birth in the open ocean at or around the mysterious "White shark cafes"...

With each one of the top predators gone, the species slips closer to extinction.

Surely these fisherman would be better off arranging to take people out to see the sharks, thus enabling them to earn an income, whilst preserving these harks?

By preserving the sharks, the fishermen will have an income and the sharks survive. A win win situation for man and shark!!

Matt

Thank you for this story, which is terrifying but not surprising.

It seems likely that the 20-footer recently killed was either pregnant or had just given birth, since the Sea of Cortez is a known birthing area for great whites. Therefore, these accidental "catches" seem highly suspicious, and if the statement is true -- that "13 large sharks have been killed during the past few weeks alone" -- then this could be absolutely devastating to the Pacific Coast great white population. I repeat, devastating.

Clearly, as the photos suggest, these sharks are being targeted for their jaws -- I suspected as much when the fisherman's wife offered to contact the shark's Monterey Bay-based tag only when she thought there might be a reward -- and it's a shame that there's no enforcement to investigate these catches, nor perform an obligatory necropsy (which would help settle the pregnancy issue).

Mexico must provide fishermen more options than harvesting sharks; likewise, the authorities should prosecute any killing of these majestic animals, accidental or not. Moreover, these jaws should be confiscated, thus taking away any financial incentive for these "accidental" catches.

Shame on these fishermen for targeting these apex predators, which are almost irreplaceable due to their slow growth to breeding age: this is the quickest path to destroying the already shaky food chain on which their livelihood relies upon. One killing a travesty. Thirteen is ineffable.

What can an average American do to combat these injustices and to raise awareness?

Deeply troubled,

Matt
