Palladium Neodymium-Hope For Sharks

What you are looking at may just save millions of sharks in the coming years. Researchers have discovered some metals actually cause sharks to be "repulsed" in salt water (if you live in a canal region with loads of Bull sharks, sorry)

Thanks Underwater Times for this story.

Sharks in captivity avoid metals that react with seawater to produce an electric field, a behavior that may help fishery biologists develop a strategy to reduce the bycatch of sharks in longline gear.

Shark bycatch is an increasing priority worldwide given diminished populations of many shark species, and because sharks compete with target species for baited lines, reducing fishing efficiency and increasing operating costs.

A recent study by NOAA scientists and colleagues on captive juvenile sandbar sharks showed the presence of an electropositive alloy, in this case palladium neodymium, clearly altered the swimming patterns of individual animals and temporarily deterred feeding in groups of sharks.

Shark Diver Hits 100,000,000!

Without a doubt the most watched shark diving video on You Tube right now was shot at Isla Guadalupe and we were in the middle of it in 2007 with white shark researcher-Mauricio Hoyos.

The video has hit over 100,000,000 views and shows no signs of stopping anytime soon. It has also launched the career of aspiring wild animal show host Luke Tipple.

You may also know him as the Dive Operations Manager for Shark Diver and Islander Charters.

What made this video a hit?

Good question. This was a grand experiment in Web 2.0 for us here at Shark Diver. We knew that the right video at the right time with a compelling story would draw interest. It also had a lot to do with how this was marketed on the net.

Without giving too much away-having the right partners, in this case the boys from 689 Design, made all the difference. Adam and Zander are pure genius, they know what works, they know timing, and they (thanks to us) also know Great White sharks.

So, in case you're one of the few shark fans who have not seen the video, here it is yet again:
