Arrr, more squid!

The headline reads "Voracious Jumbo Squid invade California!"
What a load of codswallop.
Sure, the Humboldt Squid is usually found in warmer more southerly waters, but it's not as if this is some foreign creature. Living at depths of 600 to below 2000 feet (only surfacing to hunt) and not well researched because of it, Humboldt Squid can none the less be found in numbers in the Baja region of California/Mexico where they're heavily fished by Mexican fisherman. A recent documentary showed the devastating impact this heavy fishing has on the species. While always aggressive on the hunt, the Humboldt Squid is normally a cooperative hunter, hunting its natural prey of anything from krill to hake and anchovies in groups. But when squid are being hooked and hauled aboard left and right the opportunistic predators go into a frenzy, attacking and eating anything in sight...including researcher's camera equipment. There are documented reports of Humboldts attacking divers, and famed videographer Scott Cassell has even made himself a 'squid suit' designed to protect him against their razor sharp beaks and chitinous teeth ringed tentacle suckers. Humboldt Squid only live for an estimated maximum of 4 years (sometimes only 1), growing in that time to a documented 7 feet in length. Researchers conclude that this is the reason for their sometimes uber-aggressive behavior. With such a limited time span the Humboldt Squid has to do whatever it can to survive and progress. This is also the reason why the Humboldt Squid is so adaptable, and therefore a 'problem' to California fishermen.
But let us consider the facts, kids. Why are Humboldts moving north? Could it be the pressure from fishing in the Baja region and the coast of South America? Could it be that Humboldts natural food sources in their historic ranges (aside from other humboldts) has been damaged? Or (my bet) could it be that commercial fishing has so decimated stocks of fish, both predator and prey, that the Humboldts are now filling a gap that was never there before? While the Humboldts feed on anchovies and hake (normally prey of the tuna in this region) the fishermen would love to catch, their numbers increase more dramatically because their natural predators (tuna, swordfish, shark) have been fished into a steep decline.
Why is it that when Nature is out of balance we always try to blame Nature, when really we should be taking a closer look at ourselves?
Unfortunately I can't find any organizations directly dedicated to Squid Conversation, so today you'll just have to suffice with educating yourself!

To kill, or not to kill: The Giant Squid

To scientists the answer to this question would likely be: kill! Kill with all speed, chop up into itty bitty pieces and cure in formaldehyde!
Recently, for the first time, Japanese scientist captured a live mature (mostly?) giant squid. This was the first time anyone had even caught one on film in the wild. Previously everything we knew about giant squid had been learned by studying their carcasses which wash up on shore or get caught in fishing nets and lines. Now for the first time we have photographs, graciously provided for all by National Geographic.
Scientists used bags of pulped shrimp and smaller species of squid as bait on large multi-pronged hooks to capture the beastie. You can see one of the hooks in the photograph of the squid's severed tentacle. Not a very nice 'howdy do'. The Squid tore the tentacle off when it struggled and made its escape. Lucky little devil fish. Call me a cynic if you will, but I just can't imagine scientists hauling a 25 foot long (that's roughly half the size we KNOW a giant squid can grow to, though its perfectly possible they get larger) species of squid that science has never studied up close before all the way up from the blackest depths of the ocean and then just letting it go. It would have probably ended up like this little beauty from the Philippines. Only in a rather larger jar. "Over 100 samples of rare species." If they're so gawdawful rare, perhaps it'd be best not to disturb them so much?
Now I'm not implying that the giant squid is a rare species, far from it. But that shouldn't be any reason to treat one like we can just go down to the store and pick one up, right?

This one reminds me of Cthulhu, encased in a block of ice, awaiting the day when he can wreak his vengeance upon the world, muahhahahaha. Ahem. Pardon me.

(Author's note: This is an old entry that somehow missed getting posted...since then I've become aware that sources are inconsistent in describing exactly what happened to the unfortunate squid. Some say he escaped, sans one tentacle, while others claim that he was hauled aboard and dissected. Personally, I'd like to believe NG when they say he escaped!)
