Underwater Observatory in Mozambique by Calum Murie

Underwater Africa Ocean Observatory

Underwater Observatory in Mozambique by Calum Murie

Calum Murie, when he’s not out catching and tagging huge sharks for science, can be found deploying underwater observatory style camera rigs, all over Mozambique.

Calum and his band of volunteers at Underwater Africa designed this simple but effective underwater observatory camera rig – with bait and all!

The Morey Eels love being on camera, and literally dominate the entire show, whenever Calum and crew deploy their rigs. Up in Bazaruto and Benguerra Island two huge Moreys spent literally hours trying to figure out how to get at the free bait.

Without revealing too much, you can look forward to literally hundreds of fish and other marine animals in this particularly well edited clip. Soundtrack too!

The underwater observatory work that Calum is doing up here, is the first of it’s type here in Mozambique.

You can look forward to more of Calum and crew’s phenomenal work as they perfect the art of deploying an underwater observatory in Inhambane waters. His work is constantly being refined and the cameras can now stay down longer and film more. Having developed a crew that understands the value of the results and how important it is to deploy perfectly every time, is what is producing these results.

You can learn more about Underwater Africa and their research work going on in Praia do Tofo, where they are based. Their shark tagging program has been a great success. The Sardine crew have been assisting and getting right involved. Sonar tagging Zambezi sharks, and Copper Sharks, the data is being used to formulate a plan to reduce shark and human encounters up and down this coast. The spate of shark attacks that occurred up the Inhambane Estuary towards Morrumbuene is what kicked off the project. Listening stations are deployed along the entire East Coast of Southern Africa, and record when a tagged sharks swims past.

Ultimately, proving that Zambezi (and the other usual suspects) sharks are not wanderers, that they stay on their pieces of reef and ocean, is what can lead to measures, to curb the attacks.

Zambezi Sharks don't scare him!Calum Murie wires a hefty shark for tagging with a sonar tag that can be picked up by listening stations up and down the East Coast of Southern Africa.When Calum and crew are not deploying their underwater observatory equipment, this is their other fun activity - tagging sharks!Although Zambezi Sharks are on the top of our hit list, these blacktips are also featured.The Bazaruto Archipelago is where we can find many sharks to tag. On the outside however produces the best results. This is also the place where Calum plans to keep his underwater observatory operation project getting fresh materials

If you are interested in this kind of activity and you have some time on your hands, please get in touch. We need help tagging these sharks up here, it’s not easy work, and it can be dangerous too.

Accommodation is rustic luxury and we have many boats to choose from for when we go out tagging sharks.

The Sardine is also facilitating tag and release programs for gamefish. Billfish included. But mainly targeting high value data fish that are in jeopardy and nobody has any data on them. You can see more of The Sardine’s adventure options by clicking here.

Sonar tagging Zambezi Sharks with Calum Murie

Although Zambezi Sharks are on the top of our hit list, these blacktips are also featured.

Sonar tagging Zambezi Sharks: Calum Murie could have been anything. But he chose to spend his life chasing huge sharks around with sonar tag in hand, ready to abuse the first full grown Zambezi Shark he sees. In the name of science, research and conservation, Calum’s motivation for this career path runs deep and his commitment is exemplary.

And so it was that Calum enlisted the crew and facilities at the BCSS (Bazaruto for Scientific Studies) this September, to get some more tags installed in some Zambezi Sharks and other suspects. The tags are monitored by sonar listening stations set out up and down the coast between Pemba and Cape Town. So if one of Calum’s tagged sharks goes on leave and heads off for a holiday, Calum is gonna know about it.

This behavioural study of horizontal movement is aimed at supplying decision makers with the correct information regards shark activity along our coastline. Sadly, there have been over ten shark attacks in the Inhambane Estuary just down the coast from the BCSS. It’s the poor crab ladies who are getting taken the most. They are sitting ducks working in a metre of cloudy water at best.

And so Calum is fiercely chasing Zambezi’s, the prime suspect as usual. Although bronze whalers are also on our shark tagging list for being a suspicious character. Calum is also after Tiger Sharks, but we have not been successful at this as of yet. Hopefully we can find a small one somewhere!

You can actually get involved in our shark tagging exploits if you like. The success of the project that Calum is running, has opened up more funding for his studies. More listening stations are being deployed in association with the BCSS and Dr. Mario Lebrato. And we now have another batch of tags to deploy. At over $1000 per tag, we have got responsibilities!

The BCSS was built in order to facilitate research and conservation. So if you are aligned with these objectives, get in touch to join the team for a week or two. Rates are very reasonable. And you get to stay with us out here on the edge of the whole world!

“Recently, a  2  year old 14 lb. school bluefin originally tagged and released by Anderson on October 9, 1997  was recaptured 711 nautical miles from the Northeastern edge of Nova Scotia.   At 5,855 days (or 16 years), this bluefin has the third longest time at liberty ever recorded.  When it was recaptured it weighed approximately 1,200 lb!  ”
