Here goes.
This is an important initiative.
Thanks indeed! I hope all of you will join in this effort to conserve our shark populations. And here you were, thinking you're just having fun, when you're diving with sharks.
Let's go shark diving!

How do you make a viral video?
Of course, we don't just encounter Lemon Sharks, we see plenty of Tiger Sharks as well. This is truly a trip of a lifetime! Since we only take 6 divers at a time, you'll be sure to get up close and personal with these amazing animals.
For more info on the trips and a complete itinerary, check here, or you can call us at 855.987.4275 or 619.887.4275 We are always happy to talk "sharks"!

Are white sharks parenting their offspring?
They are saying "A 9-foot-long great white shark has been spotted in Australia’s Lake Macquarie, close to the scene of another recent sighting, along with a smaller, unidentified fish that some researchers believe could be the shark’s offspring".

Who is going to be at Guadalupe?
Is "Shredder" going to show up again, after missing the last 2 years?
| "Shredder" my favorite shark. |
How about "Horizon"? As you can see from the picture below, he's not the most careful shark in the world. I wonder, if he's related to "Shredder", they seem to have some very similar personalities. His dorsal is missing a nice chunk and parts of his tail have been bitten off by other sharks on a couple of different occasions.
| "Horizon" |
Bruce, Bite Face and Jaques have been faithful visitors, showing up every year, since MCSI started keeping track of them in 2001. When we first encountered them, they measured a "measly" 11-12 ft and are now they are all 16+ ft. Are we going to see them again this year?
![]() | ||||
| "Jacques" |
The discover channel is starting their "shark week", just about the same time our first divers are going to experience a "Real Shark Week". Coming face to face with these awesome sharks is nothing like what you see on TV. You will never forget the moment, when they look straight into your eyes, for the first time. It is truly an experience of a lifetime!
To all our divers that are coming out with us this season. I'll see you soon and I can't wait to introduce you to my toothy friends. In the meantime, we'll keep you updated with pictures and stories from our expeditions, as the season progresses.
Cheers,
Martin Graf

Illegal shark fishing causes injury to swimmer.
Here is what actually happened. A man, fishing from the pier, caught a juvenile great white shark and was fighting it for 40 minutes. Trying to get away, the shark started biting at the line and in doing so, bit a swimmer. It is illegal to fish for great white sharks in California. Here is an excerpt from the California Fish and Game regulations.
"As defined in state law, “take” means “hunt, pursue, catch, capture, or kill or attempt to hunt, pursue, catch, capture, or kill.” Anyone who takes a white shark without a permit may be cited for violations of CESA and subject to criminal prosecution"
As usual, when something happens with a white shark, the shark gets the blame, not the fisherman who was endangering the public, by fighting a great white shark in waters crowded with swimmers on a holiday weekend! The headlines should read something like this "Illegal shark fishing causing serious harm to swimmer!"
Luckily the swimmer has non life-threatening injuries and we hope he'll have a speedy recovery.

Where do "our" great white sharks give birth to their young?
Back in 2000, when we started diving with great white sharks at Isla Guadalupe, we knew very little about where the sharks were going, when they are not at the Island. I remember the days, when the scientists thought that they went to Shark cafe/Sofa to mate. Thanks to satellite tagging by Dr. Domeier and his team at MCSI, we now know that males and females are not in the same place, same time in that area. Based on tracking data and the white sharks gestation period of 14-18
months, we now think that they are actually mating at Guadalupe Island.The next question of was, where do they give birth? Again, thanks to the long term SPOT tags, (we just talked about the improvements to those tags here) we now have a better idea of where that is taking place. For the females that aggregate at Guadalupe Island, it seems to be off the coast of Baja California MX as well as the Sea of Cortez. (Two-year migration of adult female white sharks (Carcharodon carcharias) reveals widely separated nursery areas and conservation concerns)

| Gill Raker's latest location. |
This is the latest post on the MCSI facebook page today, showing what Gill Rakers is up to!
"We have been waiting nearly 17 months to see where Gill Rakers will give birth. Now that we think she is heading for the Sea of Cortez, we must prepare for a stressful 4-6 weeks. The Sea of Cortez is a narrow body of water with intense commercial shark fishing. She will be running the gauntlet, through longlines and gill nets...gear that kills. Our biggest question: Will She Survive?? Watch with us on the Expedition White Shark App...and stay tuned to our FB page."
We all share their concern for Gill Rakers safety. The Sea of Cortez is not a safe place to be, for a great white shark. We hope that we'll see and get to dive with her once again this fall, at Isla Guadalupe.
Cheers,
Martin Graf

Do you want to see the big "girls" at Guadalupe in November?
That interest and the fact that our Great White Shark database is in need of pictures of the big, late season females, we have decided to add a special science expedition from November 11- 16.We are proud to announce, that Nicole Nasby-Lucas from the Marine Conservation Science Institute, the scientist that started the Great White Shark photo Id database at Isla Guadalupe, will again be joining us on this special expedition to photograph and identify the large females. She will also be sharing her research with our divers and showing everyone how to identify the sharks. So far the database has over 150 individual sharks identified and some of those individuals have visited Guadalupe Island every year since first being identified in 2001. It is amazing to see how those sharks change in size and behavior.
This expedition is a unique opportunity to participate in growing our database. Should we find a new
shark, which is fairly likely during that time of the year, the group will get the opportunity to name the shark. Imagine
seeing a shark on a future television documentary, knowing you were
there when we first encountered it. All the participants will also get a copy of the photo ID book, containing all the identified
sharks at Isla Guadalupe.The price for this special expedition is $3300 and is limited to 18 divers. We recommend that you book early, since our last two science expeditions sold out in just a couple of weeks.
To book or for more information, call us toll free at 855.987.4275 or 619.887.4275. You can also reach us via email at staff@sharkdiver.com
I hope you can be part of this exciting expedition!

Baby Bull Sharks in Fiji!
A little while ago, we talked about Project abroad and their involvement with the sharks in Fiji. It is this same organization that is tagging these sharks as well as taking DNA samples for research. Kudos to both Project Abroad and Bequa Adventure Divers for all you do to help understand and protect our sharks. We at Shark Diver can't wait to come visit you guys in May. Anyone that wants to join us, we have 2 trips available. From May 2-11 and May 9-18
Call us at 855.987.4275 or 619.887.4275 to reserve your space.
This is a unique opportunity to dive with as many as 70 Bull sharks at once and discover first hand, what over 10 years of conservation efforts have accomplished in Fiji.

Do you want to save the sharks in Hawaii?
Hmmm, not quite! Their approach is a tiny bit different, instead of culling sharks they are considering penalties for harming sharks! You can read the full text of the proposed bill here. Since this bill has not been passed yet, they need your help. You can tell them why you support the bill here, OMHTestimony@capitol.hawaii.govEco tourism, Isla Guadalupe, Tiger Sharks, Galapagos Island, Whale sharks
The reasons mentioned, for wanting to implement penalties for harming sharks are,
SECTION 1.
The legislature finds that sharks and rays are extremely important to
ocean ecosystems. As ocean predators towards the top of the food chain,
sharks and rays keep the ecosystem balanced, regulate populations of
other marine life, and ensure healthy fish stock and reefs.Again, it's important to note, that this is only a proposed bill and has not been passed yet. Don't forget to support the bill by sending your comments to OMHTestimony@capitol.hawaii.gov
Let's help those legislators who are fighting for our oceans and all the creatures living in it!

Who is really saving the sharks?
Just do a search for "shark" on facebook and you get a seemingly endless list of groups that want to save sharks, but most of them do nothing, other than commiserate with each other.Great White shark, cage diving, swimming with sharks As a company that deeply cares about our oceans and the sharks that live in it, we like to support and work with the organizations we feel are doing a great job, not just talking about conservation, but really doing something about it.
We are proud to say that our Fiji partner, Bequa Adventure Divers, has the same philosophy. They helped establish the Fiji "Shark Reef Marine Reserve" and I love the way they describe themselves as a "conservation project, masquerading as a dive operation". You can read about their philosophy and actions here. Their approach to partner with the local fishermen is awesome and their success proves, that conservationists and fishermen can work together.Great White shark, cage diving, swimming with sharks at Isla Guadalupe are specialties of Shark Diver
Beqa Adventure Divers has also partnered with Projects Abroad a great organization, working, not only to protect sharks, but helping in a lot of different areas. Mike has written an excellent blog about them here.
We are going to Fiji this May, to dive with Bull Sharks and to check out the possibility of organizing a volunteer trip for next year. If you would like to join us on our Fiji adventure, dive with up to 70 Bull Sharks swimming around you and check out what Mike and his crew are up to, call us at 855.987.4275 or 619.887.4275 staff@sharkdiver.comGreat White shark, cage diving, swimming with sharks at Isla Guadalupe are specialties of Shark Dive

Richard Branson, voice of reason?
In 13 years of diving with Great White Sharks at Isla Guadalupe, I have observed that the smaller sharks are actually more inquisitive than the larger individuals and are likely more apt to bite something in order to investigate what it is. So even if the drum-lines would only catch the large sharks it intends to, we have to ask ourselves, are we even trying to catch the sharks that are most likely to bite a human?
Here is the problem with the approach with us shark experts and conservationists. We look at the problem from a shark related perspective. There is nothing wrong with that, but we have to address the real reason the shark cull was started.
| Sir Richard Branson, foto wildaid.org |
I believe that Richard Branson knows a thing or two about tourism and promotion. Hopefully premier Colin Barnett will listen to his voice of reason, if not for the sake of the sharks, then for purely economic reasons, to protect the way of life and the tourist industry of Western Australia.

Which Great White Sharks are back at Isla Guadalupe?
For all of you that have come out with us before, I'm happy to report that our friends Bruce, Chugey, Thor, Gunther, Drogin, Bite Face, Jaques, Quetzalcoatl, #89, #130, #132 # 138, #146, Johnny, Horizon, Reb, Diablo, Atlantis, Kimel, Squire, Joker and Monkey have all safely arrived at Isla Guadalupe and are entertaining our divers, like Lucy and Ben Challenger who have sent us this video. Ben of course is none other than this guy and Lucy this young lady
No sign of Shredder yet, but the fact that Quetzalcoatl came back after not having been seen for 8 years, gives me hope that he will come back as well. I can't help but get attached to "my" sharks. Something happens, when they swim by and look you straight into the eyes. I can't explain it, you just have to experience it for yourself.

Monster Shark in China?
The article states: "Fishermen in Rizhao, Shandong Province, hauled in an utterly massive 10-meter-long (32 foot) whale shark on Sunday, and took plenty of photos as a friendly reminder that oceans are terrifying places full of monsters. The giant fish weighed some 10,000 kilograms and was dead on arrival, but the fishermen brought it back to land where, with the use of a crane, dropped it into a truck."
The ocean is a terrifying place, full of monsters? Now just in case someone is not clear on this, whale sharks, while indeed massive animals, are feeding on plankton and are NOT a predatory shark! What is terrifying, is the fact that there are still "journalists" out there that write this utter rubbish, without having any understanding of what they are talking about and a newspaper publishing it, without checking any facts about these gentle giants.
The article concludes with: "This shark, along with that terrifyingly massive beast a few years back, serve as steady reminders to never go into the ocean ever."
The "terrifyingly massive beast a few years back" was also a harmless whale shark, a fact the author actually alluded to a few times in that blog post. Is that journalist, Eric Crouch, actually as stupid as his article suggests or is he just looking to create controversy?
Idiots like these try to scare people, instead of informing them. They never let a good fact get into the way of a headline!
We at Shark Diver are trying to educate people and give them a first hand look at how sharks really are, by taking them to Guadalupe Island, Bahamas or Bequa lagoon in Fij to dive with and experience sharks first hand. We also started shark free marinas to raise awareness of the declining shark populations. It is frustrating to see, that there are individual "journalists" out there who either don't take the time to research the subject of their article, or worse, purposely spread misinformation, simply to be able to create a sensational headline.

Maldives Whale Sharks - Conservation
In another step towards becoming environment-friendly, the Maldivian government unveiled plans yesterday to designate three whale shark habitats in the Maldives as protected areas.
Protected areas are allocated Baa atoll Hanifaru, Baa atoll An'gafaru and Alif Dhaal atoll Maamigili as protected areas to commemorate World Environment Day and World Ocean Day on the 5 and 8 June respectively.
"We welcome the whale shark sanctuaries," said Ali Rilwan, executive director of environment NGO Bluepeace today. "We don't need paper parks, we need monitoring and more research in these areas." In March, the ministry of fisheries and agricultures extended the moratorium on reef shark fishing to cover the whole of the Maldives as part of a move towards a total ban on both reef and oceanic shark hunting.The main objective of the project was to protect the areas mega fauna, namely whale sharks, Manta rays.
Divided into various zones, in which different activities will be permitted. While diving and snorkeling would still be allowed, a set of guidelines would be provided to instruct on how to deal with encounters with whale sharks.
Further, boats including Liveaboards and dive boats will be subject to speed limits in certain areas, he said.
The reaction of local residents was "very positive". "They actively wanted this to happen and this won't impact any of their activities so they have nothing to lose from this," "That's the findings of the consultation."
The decision would have a "global significance" and the areas were among the few in the world where whale sharks could be spotted.
The polka-dotted whale shark is the largest fish on the planet, but very little is known about their existence, according to the Maldives Whale Shark Research Programme's website.
While it is known they swim potentially vast distances across the ocean, eating only plankton, tiny fish and squid, how long they live or where they reproduce remains a mystery.
It was crucial to establish a set of guidelines to counter the impact that the growth of tourism would have on whale sharks in future years.
At present, it is estimated that whale shark excursions generate US$10 million annually.
According to researchers Maldives have spotted 115 whale sharks, although the real number was probably higher.
"Some of these areas are important feeding grounds," "And out of all of them, there are only two females, so the animals are only spending part of their lives here."
The designated areas would also protect other animal species such as manta rays in Hanifaru and Gray reef sharks and White tips reef sharks in Baa Atoll An'gafaru.

The New PT Barnum - Sharks
Where there's a market and demand - people will find sharks:CHICO — For Holland native Philip Peters, a decision to spend several times a day hugging a shark was the safer career choice.
A self-described daredevil, Peters used to travel with the Ringling Bros. and Barnum & Bailey Circus, performing death-defying stunts. He spent years being thrown out of canons, on the flying trapeze and "wheel of death," and wrestling with lions and tigers.
"I saw too many hospital rooms in that time and I was looking for something safer, so I started sharks and it is safer, believe me," Peters said with a laugh.
Interested in moving the sharks he planned on interacting with, Peters began researching traveling tanks. After much research, Peters developed a complex filtration system enabling him to transport a 7,000-gallon saltwater tank.
That tank is currently at the Silver Dollar Fairgrounds this week for Peters' 20-minute show, the only current traveling shark show in the country. For two-to-four shows each day, Peters amazes a delighted crowd by diving into the tank and swimming with four sharks.

Tammy Jo Anderson - Op Ed Guam
Tammy Jo Anderson is the education coordinator for UnderWater World Guam and an advocate for sharks. This week she offered a well thought out Op Ed on the reasons for keeping wild shark populations. Here is an excerpt:Sharks are a different story.
These fish have been swimming our oceans for millions of years before even dinosaurs were walking around on the planet. Sharks have survived massive changes in climate and numerous other hazards to make it to today.
Now, the main thing that is threatening their existence is us.
