Shark Guardian comes to Koh Tao

Shark Guardian presentation at Choppers



Shark Guardian is an organization dedicated to the conservation of sharks through education, promoting research, and protection and sustainability of the marine habitat to safeguard the future of these amazing fish. One of their primary ventures is the Shark Guardian presentation, a multi media production for all ages aimed at bringing awareness to the important role sharks play in our marine ecosystems as well as our planets future and the need to protect them. It combines education on the different species, interesting facts, conservation and what we can do to make a difference in maintaining their survival.

Shark have survived almost 450 million years, maintaining the delicate balance of our marine ecosystem. They are at the top of the ocean food chain and are vital to maintaining a healthy ocean balance and are an important indicator of our ocean's health.  They even indirectly maintain coral and seagrass which produce most of the worlds oxygen. Depletion and elimination of the shark population would cause an imbalance in the equilibrium of our oceans and have devastating effects on the earths environment.

The course takes 3.5 days to complete and includes 4 lectures and 4 dives including one at our coral nursery. The lectures covering everything from the ocean environment to current impacts to our reefs. You will learn how to ID fish and coral species, and gain practical experience in surveying and coral transplanting.

Marine Conservation course schedule July


The BSAC Marine Conservation Speciality Diving Course

  1. Ocean environment - in order to truly understand our aquatic environment, we must first know about the oceans composition and processes as a whole. All our oceans are connected, and one minor change in one ocean can affect the entire ecosystem.
  2. Coral Reefs - including marine identification dives and night dive. This is the most rewarding section of the course. You will learn alot more about underwater organism identification, including coral anatomy and biology. After this section, you will get so much more out of your dives.
  3. State of the reefs - Our oceans are in a rapid state of decline, and as divers we are in the perfect position to do something about it. But first we need to fully understand what is happening.
  4. Conservation - including two ecological monitoring, reef restoration and practical conservation dives. Here you will learn what you can do to contribute to conservation and preservation of our aquatic world.

This 4 day, 4 dive course is only 8,500 baht and includes course manual, all dives, equipment and teaching.

Nat in the eco labMy Eco Internship Experience - June 2014

The first time I came to Koh Tao, was in May 2013 as part of my travel around the world. I dived with Big Blue Diving and enjoyed it so much that I had to come back. A year went by and now I've just finished a month as a eco intern with Big Blue Conservation.

With the internship I've not only learned about marine biology and conservation, but also getting specialised in nitrox and deep diving, CPR training, how to be a better diver and how to treat our most important element in a way so the next generations can enjoy its beauty as well.

Nat on a boatApart from diving with whalesharks, turtles, black tip sharks and loads of other fish around Koh Tao, I've really enjoyed our nursery dives just out of Sairee Beach. The coral nursery is where I can not only feel but also see that we're doing something good for our reef, and with the teaching in BSAC marine conservation I've also learned that even the smallest things make a change.

With Big Blue it's very easy to get lifelong travel friends, my global dive family has extended and this month wouldn't have been the same without any of the people I've met at Big Blue, DMT as well as instructors and fellow eco warriors.

This summer has changed my point of view towards our oceans, and I can definitely recommend getting into marine conservation to everyone who wants to do something different while traveling or just for the summer. With Big Blue Conservation you get to see how the other two-thirds of the world live.

Lenora making bins for plastic bottlesLenora's Eco Internship Experience

"Participating in the BB Eco Internship went beyond my expectations.

It opened my eyes and expanded my mind to the true beauty of our oceans and their immense importance to our environment. The program was educational, with the instruction being followed up with practical activities to immediately apply what we learned.

Lots of diving earning several certifications in the process was an added bonus. From working in the nursery, to coral charting and ID with plenty of time for fun dives in between, it was a great balance to enjoy all aspects of the program and Koh Tao. A fantastic experience overall. "

Swim for Sharks 2014

Shark guardian.orgAn event we organise every year where we aim to make people aware of the decreasing shark populations worldwide, whether from by-catch or finning, the removal of such an apex predator can have disastrous effects on the overall ecosystem within the ocean.


This year we had great help from the organisers of Shark Guardian, Liz and Brendan, who did talks for everyone, educating lectures on how detrimental this could be if we allow it to carry on, plus the damage that has already been done, so a great thank you to them.



Swim for sharks 2014 We would also like to thank our sponsors from all over the Island, which meant along with the swim we were also able to organise a raffle with some amazing prizes, from this raffle and other small events we raised a grand total of 100,000 Baht for shark awareness.

Beach Clean

beach clean Every month we try to do our part in protecting and preserving the reef, enabling it to blossom with life, by removing any artificial contaminants that can have a detrimental effect on the reef.

This month was no exception with up to 30 volunteers helping this month we filled 6 full rubbish bags when walking along the beach and another 8 full bags when diving off North Sairee, all with unwanted waste that was littering the ocean.

With the growing popularity of Koh Tao within the Diving and general tourist community, we need to minimize our impact by working together to keep our beautiful paradise clean, or someday the consequences could be irreversible.  That day was a good example of community care.

Taiji Bay (The Cove)

Here it comes again the event all animal lovers hate, every year in Japan thousands of Dolphins are killed for their meat and a select few captured for human entertainment. The meat is full of high levels of mercury, which can be toxic to small children.dolphins trapped

The Dolphins that naturally migrate towards the coast for food, are herded in to a bay where they are then stopped from escaping my nets across the bay, and their fate is then in the hands of the killers, carrying knives and spears.  A few will survive only to then be forced to live in a small tank for the rest of their lives, trained to entertain humans with their tricks, all of which cruel in its own right.

So all I ask is that you open your eyes, to this disaster of human behaviour, I commend the work of Sea Sheperd and Ric O’Barry, in their efforts to stop this, and only wish by spreading the word via facebook and our web page, I can help in a small way.

Please visit there pages to see the progress they are making, along with the difficulties they face every day.Dolphin Murder

Visiting the nurseryinterns cleaning the structures

Here at Big Blue diving we strive to do our part in helping this beautiful island stay amazing, whether from cleaning the beaches and reefs, to even encouraging new life in areas of desolation.  Just off from Sairee beach we have been developing to coral nurseries, one at 6 meters and another newer nursery at 12 meters, both have artificail structures which will encourage the growth of many coral species.  Yesterday the team at Big Blue Conservation, went out to our shallow nursery to remove the excess alae growing on the structures, and take care of general maitenence of the structures.  We were also able to find some small healthy coral specimens that we were able to add to the structures, hoping it will in the future blossom. 

The location for the nursery was chosen, because it seemed to be a deserted area, however now thanks to the nursery there are hermit crabs, and nudibranches all eaching the shelter the structures offer from predators, and to help in our efforts we even saw some parrot fish do their part in cleaning.  It was a privilige to also see a reasonable sized anemone fish family near by. All in all it was a lovely afternoon of cleaning.saddle back anemone fish near nursery

Septembers amazing volunteer

"A year ago, I went to Koh Tao to complete some specialities and saw an ad about the eco internship. I simply thought "Oh, it seems cool." About marine biology, I was like Jon Snow, I knew nothing. But still, I wanted to do it, to somehow broaden my diving horizon.elinor next to her new nursery

So I came back on August 2014 as an Eco Intern. I first met Lizzie and it was the beginning of one of the most crazy rewarding stress free awesome heart breaking experiences in my life. No seriously, if you've ever been on Koh Tao and dove with Big Blue, you know what I mean. Basically, most of my day were: diving in the morning (for fun or for eco missions) and enjoying my afternoon on Koh Tao.Taking the new structure out

Don't believe it was some kind of lazy thing. I had to work! On holidays! I even had an exam! And we did a lot: surveys, nurseries. Coral watch. Oh my Buddha: coral watch. Going diving with a slate with 24 squares of colours, 4 colours, and 6 shade’s for each, from white (bleached) to dark. And you have to pick up random coral, match its lightest and darkest parts with the shades on the slate and it will give you a rough idea of its health. Sounds easy, right? IT IS NOT. Well, at 5m, it's okay. But at 10m, red disappears and all those coloured squares look exactly the same! Even with a torch! "Hmm is it a brownish-brown or a reddish brown... oh no, maybe a greenish brown..." Totally felt like a colour-blind... The Eco dives I loved the most were by far the ones on the nurseries.

I keep talking about the coral growing there, how awesome and rewarding it is to discover to tiny colony of polyps that has simply started growing there on its own, with us tiding, sewing it on the structures. Baby corals. "They are corals, Elena, they can't be cute...” yeah sure, they don't do funny things, like fetching the stick you've just thrown or anything "responding"... But being down there, cleaning the structures to help more corals and baby polyps to grow, fighting algae and sponge with nothing but a toothbrush (YOU SHALL NOT KILL THE CORALS !), putting new structures down in order to create a nurseries, a new place for coral to grow, for fish to live... It feels like you are doing something. Something that will last over an extended period of time. It's nothing compare to the eco stuffs you can be proud of like putting plastic bottles in the recycle bin or turn the light off. No it's more like a relief. Because you stop damaging this world, you help it to heal. And in ten years, twenty, maybe a new reef will have grown, with a lot of fishes around. If I go back down there again, I would think "It's my reeeeeeef !!!!"

I would rather think "it's my world" and I did what I had to do to protect it, because I am a part of it. Even more as I diver, it is my oceans, my playground and if you want to enjoy it and to be amazed by it for the next 50years (at least) I must understand it and protect it. We should not have to do it though. We should not have to clean up beaches or to do underwater clean-up. Because it should come naturally to anyone's mind that they are responsible for this world, of their world. So no, I should not have to do that but I will, as long as it is needed, because I am an Ecowarrior now.

Thank you Lizzie. Thank you Rachel. Thanks Big Blue. Thanks Koh Tao."

Cleaning Sairee Beach and Hin Wong Baycleaning sairee beach

Well every month we try to relieve the Island of its clutter, by doing a beach and reef clean-up, with the help of our amazing volunteers. And last month was no exceptions, with over 20 volunteers, we were able remove all the damaging substances from Koh Tao's busy Sairee beach, before they slipped into the ocean, causing more damage. For the reef clean we went to Hin Wong Bay, a bay on first appearances seems to be free of any trash, as the bay was almost deserted, however once we descended beneath the surface, we found an abundance of damaging trash, that could have been washed in or simply tossed overboard by inconsiderate captains, and their crew.  However by the end of the day our trash bags were full and we all felt the day was highly rewarding.bags of trash


Good job guys!

Development of Sairee's new reef.

Coming into the end of high season here on Koh Tao, means you generally slow down, however here at Big Blue Conservation, we did nothing of the sort. The beginning of the month was spent expanding our knowledge in ecology and diving, along with data collecting and research training. Although towards the end of the month that’s when the hard work did start, we had some relocating of some of our original reef structures, plus the development of the newer ones. Aim was to build, position and cover then cover the structures in new colonies, by the end of the month, and as you can see from the pictures we did just that.

Questions are asked as to why put metal and concrete structures, into the ocean, essentially adding to the clutter left by humans every day. Well the answer is to provide a home and shelter in a barren land, sometimes nature just needs a pick me up a helping hand. By building structures that then become covered in vast species of coral, we ultimately create shelter for a variety of marine life, great and small.
