2010 Shark Diving Report - Cage Diving at Guadalupe

For our divers 2010 has been the Trip of a Lifetime so far. Celebrated with email blasts to friends and Facebook posts to the world.

These lucky divers have met the most charismatic, studied, and filmed white sharks on the planet.

For newly minted Shark Diver Craig Reynolds, nothing but his own Great White Blog to recount his adventures this year would do:

Day 4 – TWO BLACK EYES- Knowing that sharks are active feeders at dawn – due to the favourable light conditions it provides for hunting – my cage team volunteers for early morning “shark lookout.” Really, it just sounds like an extra hour for keeners so we’ll take it, thanks. And one hour quickly turns into two.

The sharks are slow to venture up from the bottom for the first while. Their grey topside blends in almost perfectly with the abyss below our feet. The white tips of their flanks appear to be nothing more than small fish from far away. And as your mind starts to play tricks on you, the small fish start to look like White Sharks.

But by the second day, we’ve grown more accustomed to our steel confines.

Gradually, you start to find ways of hooking your feet around the ladder and pivoting your body like a climber, hanging on to a bar with a couple of fingers while the others hold the camera, and leaning with the current instead of against it. Your movements become more efficient as does your breathing that bordered on hyperventilation the previous day. I can only imagine how fast your heart would race if you were outside of the cage...

How to interact with white sharks - California

No screaming, no panic, no fear. This is Homo Sapien and a tagged Carcharodon carcharias meeting in the open ocean off the coast of California this week.

Kudos to Grind TV for the story and to Chuck Patterson for a once in a lifetime moment with whites that showed the world how interacting with these wonderful critters can be done without the hype:

Fine News for Lemon Sharks - Florida

News Release

February 18, 2010
Contact: Lee Schlesinger, 850-487-0554

The Florida Fish and Wildlife Conservation Commission (FWC) approved a rule Thursday to prohibit all recreational and commercial harvest of lemon sharks from Florida waters. The FWC took this action to protect lemon sharks, because they have a high potential to be overharvested.

Lemon sharks are often found near shore in shallow water, especially in Southeast Florida, where they aggregate in large numbers each year. This makes them easy to locate and raises the potential for large numbers of lemon sharks to be removed from the population with minimal effort by fishermen.

Lemon sharks also are susceptible to overharvest because of their life history characteristics. They are slow-growing, reaching sexual maturity at 12-15 years of age, and have a low reproductive potential, producing 6 to 18 pups per litter every second or third year. Juvenile lemon sharks experience a mortality of 40-60 percent.

Recently, some preliminary data from an ongoing tagging study found that at least 7.5 percent of tagged adult lemon sharks from a Southeast Florida aggregation succumbed to fishing mortality in one season. At that rate, the entire lemon shark aggregation could be harvested in a few years.

In addition, recent regulatory actions for other shark species might put more fishing pressure on lemon sharks in Florida waters, where 90 percent of known lemon shark aggregations occur. The harvest of lemon sharks will still be allowed in offshore federal waters adjacent to state waters.Healthy lemon shark populations are especially important to Florida's dive charter industry which provides ecotourism trips to see lemon shark aggregations in the winter months.

The FWC's lemon shark rule takes effect on March 23. More information about recent shark-management actions is available online at MyFWC.com/Rules, click on "Fishing - Saltwater."

Messaging the shark diving experience

Slowly but surely, expedition videos and images are changing on You Tube and other media sites. Shark diving messaging is something the industry should encourage as a conservation force multiplier.

Here's one example:

"Human and shark, who is the real predator of the sea? Almost 100 million sharks are killed by human every year because of shark fining."

GEERG Shark Cage in Montreal

Hard not to like these guys with a name like GEERG. If you happen to be in Montreal (our all time favorite city) drop by:

The GEERG anti-shark cage will be in Montreal and scuba divers will have a chance to experience the feeling of being in the cage.

The GEERG cage will be at Total Diving’s annual picnic at Kahnawake Quarry on June 20, 2009. Scuba divers will be invited to go in and get an idea of what’s it’s like to observe sharks from behind bars.

This cage will be used, later this Summer, for a National Geographic documentary on the Greenland shark.

GEERG is the Greenland Shark and Elasmobranch Education and Research Group. It’s mission is to study the Greenland shark and other Canadian shark species in their natural environment. GEERG Director Jeffrey Gallant will be with us on June 20 to answer all of your questions. Jeffrey is also the Executive-at-Large of the Canadian Association for Underwater Science.

Total Diving is a scuba diving school in Montreal, QC, Canada.

Total Diving’s annual scuba diving picnic, is a family event to celebrate the beginning of the 2009 diving season in Montreal. During this event, divers have a chance to try all kind of underwater toys at no charge, with a Total Diving dive professional on site to help them. For instance, besides the GEERG shark cage, there will be a complete underwater communication system with full face masks for 2 divers and a surface station, a vehicle recovery system, a hybrid between a dive mask and a dive computer, and a whole lot of gear from Atomic and Bare.

This year’s picnic will be held at the Kahnawake Quarry on the Southshore of Montreal. This quarry is just, now, being re-opened to scuba divers.
