the photographer
the diver in the photo is rudi robisch, the bavarian manager of the other orca dive club in hamata. together, they found some nice objects like this small school of batfish.
gerald and rudi even found some big fish like this malabar cod which is great news to us and the new dive shop.
finally gerald found these two - at 6 o'clock in the morning. that's why we look a bit tired. thanks, gerald, for the pictures. we really enjoyed your company.

diving the red sea
working on dive boats in egypt is an easy job compared to the work divemasters have to do in australia. all the hard work - filling tanks, transporting cylinders and gear to and from the boats - is done by the egyptian crew members. all we have to do is to make sure everything runs smoothly and to look after the divers. sometimes we feel like guests on the clean and tidy boats ourselves.
the dive sites are mainly colorful coral gardens. probably the most beautiful hard and soft corals in the world. but there is not much big fish left in these waters. obviously, it has all been fished out by the egyptians who even used dynamite for many years. i learned scuba diving in the red sea 15 years ago but it was a completely different story back then. there were big fish and sharks everywhere. but now? in four weeks we haven't seen one shark. so, we started taking pictures of ourselves instead.
sometimes we get to see a 'big cod', as they say here, but the fish they mean would be considered a rather small cod at ningaloo. we appreciate the marine life at ningaloo even more since we dive here. it reminds us of how it once looked here in the red sea before they threw dynamite overboard. i hope the ningaloo reef will not face the same fate with all those recreational fishing boats going there in increasing numbers these days. it becomes a rather sad experience to find one single big fish in the sea after weeks of diving, like the big napoleon wrasse we encountered two days ago on a dive site called 'shaab claudio'. when it approached us, we saw that its lips were badly deformed and infected, from being fed by hand or from a fishing hook - we don't know. to us, this magnificent fish looked rather lost and lonely.

salam aleikum from egypt
fränzi and i decided to go somewhere else for a while. we accepted a job offer from a company in egypt. fränzi always wanted to dive the red sea. so, why going there as a paying tourist for a week or two if we can go there for a year or so - and get paid?! the job is to open a new 'orca dive club' in the south of egypt, near the sudanese border where it's less crowded than up north. they just build a new four-star hotel near a tiny village called hamata - our new home for a while. when we got here a few weeks ago the hotel had just opened but the work on the building for the dive shop was put on hold because of the 'ramadan' in september. it's the building on the right hand side. in the background the red sea including our 'house reef'.
we thought living in a hotel is gonna be tough but it's not. we enjoy the service, the egyptian staff are very nice people and we love our large room with a dome-shaped roof and a large balcony.
i reckon we'll become really lazy here as we never have to clean, cook, do the dishes or anything like that. they even do the laundry for us, including ironing. life really is not too bad here...

whale shark attack!!
but not just that. i filmed something probably no one else in the world has ever encountered before: a whale shark attacking another whale shark! we snorkelled on top of a four meter shark cruising along in about 5-6m of water when all of a sudden a huge (8-10m) whale shark came out of the blue from underneath the smaller shark and clearly attacked and chased it. unbelievable! the water was quite murky but you can still see the attack in my footage:

gentle giants in decline
the iconic whale sharks that congregate at ningaloo reef off western australia are declining in number, according to a recent study published in the journal of animal ecology. researchers from the australian institute of marine science and charles darwin university have used 12 years of whale shark photographs from ningaloo reef to monitor and predict trends in population size. the scientists’ models show a steady decline in numbers of the giant fish. the study follows increased efforts over the last decade to learn more about the ningaloo whale shark aggregation due to fears that over-harvesting outside of australian jurisdiction could pose a threat to the gentle giants. ‘australia’s whale shark population is shared with many other countries in southeast asia and around the indian ocean,’ says fish biologist dr mark meekan. ‘although many countries including india and taiwan have recently halted or reduced their commercial take of whale sharks, continued harvesting throughout southeast asia is probably still occurring.’

whale shark products are sold in many southeast asian countries. it is reputed to be the world's most expensive shark meat. there are various products used from whale sharks including:
- cartilage, blood, gall bladder, corneas and liver are used in a variety of medical treatments
- the meat is eaten and sold as flake or shark meat in fish shops
- the fins are considered a delicacy in asian cooking (shark fin soup)
- the skin can be turned into leather
- the liver oil is used in cosmetics

more sharks for us aquarium
two more whale sharks appear to be on their way to the georgia aquarium. fisheries officials in taiwan are ready to approve the export of the male whale sharks to the atlanta aquarium, said a whale shark expert on the east asia island who has reviewed the aquarium's applications. one of taiwan's largest newspapers reported this week that officials have signed off on the transfer."they will probably be exported to the united states in june," said z. shouzheng, an associate professor at national taiwan ocean university. the whale sharks' arrival would raise to five the number of the creatures, known as the world's largest fish, circling in the aquarium's ocean voyager exhibit. the decision to ship the sharks represents an apparent change in opinions about the aquarium's care of them. a male whale shark died at the aquarium in january, prompting questions about a chemical used in their tank to treat parasites, which could have curbed their appetite and led to force-feeding of the fish. the 22-foot whale shark, named ralph, died from peritonitis, an inflammation of the stomach lining. he also had perforations in his stomach, possibly caused by the pvc pipe used to force-feed the leviathan. the aquarium has declined to release the necropsy report detailing the cause of ralph's death. ralph came to georgia in june 2005, along with norton, another male. both were in ocean voyager when the aquarium treated the sprawling tank with a chemical to prevent leeches. the two fish soon stopped eating, prompting the force-feedings. norton is still undergoing the feedings, the aquarium said.

stuffed whale shark
the largest flordia keys fish story took place in 1912 just off of knight's key. captain charles chompson of miami harpooned a 38-foot-long whale shark that reportedly took about 39 hours, five harpoons and more than 100 bullets to subdue. the 26,594-pound whale shark was towed to miami, preserved, stuffed and exhibited on a railroad flat car. the sign on the flat car read "weight 30,000 lbs. length 45 ft." all went well until it was accidentally destroyed by fire in 1922.

whale shark under boat II
to find out the sex of the whale shark i had to duck dive right next to it. usually whale sharks bank or turn their back towards you for defence if you come to close. this shark didn't bother at all, it even turned its belly towards me.

whale sharks of ningaloo
whale sharks will grow to over 12 metres in length, which is about the size of a large bus. whale sharks are not aggressive, they cruise the oceans feeding on concentrations of zooplankton, small fish and squid. whale sharks occur world-wide in tropical and temperate seas and are thought to be highly migratory. however, there is little information currently available on this aspect of their behaviour. also, the population is unknown and the species is considered vulnerable. for better understanding (and better protection) of the whale shark it is important to collect as much data as possible. a few years ago a non-profit organisation called ecocean introduced a worldwide photo identification library. in the next few weeks, i'll report all my whale shark encounters to ecocean and you'll also find some of them here in my blog.

welcome to ningaloo
it’s my fourth year living in exmouth and still i just cannot complain - i love it here! most of my friends back home in germany don't really have a clue what i do here - so i decided to start my own weblog. me and my camera want to give you an impression about my life in a very special place on this planet.
the australian north west cape is a very remote peninsula with just one little town of 3000 people, 1200km away from a proper city, 800km away from any traffic lights. paradise is just around the corner: pristine beaches, an almost untouched coral reef, a clean warm ocean plus the fascinating australian outback. all this is very crowded - with animals, not people: welcome to ningaloo reef and cape range! i spend a lot of time diving with all sorts of pretty fish – from the smallest to the biggest ones, which are in fact the whale sharks. these gentle giants visit ningaloo reef every year from march to july. you will learn more about them very shortly – i hope you will come back regularly to check out what i'm up to. so long – take care!
