Big Blue Conservation - Projects

The Big Blue Conservation Reusable bags have finally arrived!!eco bag




In our attempt to keep our seas and beaches clean and to rid the island of plastics bags which cause significant harm to numerous marine life, Big Blue Conservation now sell Reusable (and oh so fashionable) recycled-canvas bags.

Check them out! And at only 150 baht each, with 50 baht going straight back into conservation, how can you refuse? Do something good for the environment, and look good doing it!

It's the opening of this years season in the Similans, so the crew of Big Blue Conservation made their way across to sunny Khao Lak and boarded Big Blue's very own liveaboard boat, the MV Pawara. The 4 day trip included some ornate ghost pipefish, leopard sharks, seahorses, cuttlefish, octopus and many a colourful nudibranch!
The Similan Islands are part of a Marine National Park, where fishing activities are banned. With granite rocks and exposure to different currents, the west coast of Thailand has very different marine life compared to Koh Tao in the Gulf of Thailand. Lots of soft corals and granite rock formations dominate the aquatic landscape, and is frequently visited by large pelargics such as Manta Rays and the gentle Whaleshark.
So have a look at the pictures we took last week - you'll not want to miss out on this, so book your trip on the liveaboard now!


Koh Tao has gained exponential popularity over the last five years, however still suffers the primitive waste water system that cannot sustain the current demand. For the last 4 years, companies have been building over the evidence, the grey water stream that runs through Sairee Beach. Big Blue has not covered it up, in an attempt that some day we may be able to improve the water quality that current expels directly into Sairee Bay.
Enter Big Blue Conservation!
Constructed wetlands uses reeds and other wetland plants to filter and recycle waste water through their roots. A constructed wetland consists of a gravel bed on which suitable wetland plants are grown. As water passes through the substrate, it is purified through the activity of bacteria attached to the gravel, plant roots, soil and other particles. The many natural processes operating within constructed wetland ecosystems are dynamic, robust, and offer superior wastewater treatment that is difficult to reproduce mechanically or chemically. The systems can withstand shock loadings and volume changes while maintaining a consistent discharge quality clean enough to be released straight into the oceaan, as the Poonama canal does. There is a growing body of research characterizing the ability of wetland plants to neutralize complex organic compounds including pharmaceuticals and pesticides, thus making it safer for bathers and recycling. They are long lasting, low maintenance and naturally regenerative. As natural habitats for many butterflies and plants, the wetland would provide an attractive entrance to Big Blue, therefore providing aesthetic, commercial and habitat value.
Its cheap and easy to build, and part of becoming an SSI Eco Dive centre requires us to manage our waste water as best we can. By investing in a constructed wetland system, you can truly claim to be a responsible steward of the environment, bringing human activity more closely into balance with nature. You can reduce your impact on municipal infrastructure, help conserve waste water with the potential for reuse, and help to provide wildlife habitat, all while treating wastewater to high standards for release into the ocean.
So watch this space - there going to be a beautiful wetlaand awaiting you next time you come to Big Blue!

Staff, DMTs and eco warriors alike joined forces yesterday for a full day of meccano making fun! we constructed 6 separate coral nursery structures and put them down off Sairee. Coral nurseries are an excellent way to help the rehabilitation and restoration of reefs, by taking fragments of coral which would otherwise perish in the sand and giving them a nice hard surface to grow! Thanks to everyone that helped - you finally got to play with coral! Great effort and big thanks to Prince of Songkla University for helping us with the project.

2010 has been an extraordinary year around the world. Very warm sea temperatures due to the ENSO effect, coupled with flat, calm seas and intense sunlight on Koh Tao has lead to severe stresses on our corals. Most of the coral bleached, a good proportion of them are currently in a state of recovery and unfortunately a few have died.

In light of these events the people of the Save Koh Tao Group, together with the Department of Marine and Coastal Resources and scientists from the Prince of Songkhla University have embarked on an ambitious project to regenerate the coral population of our small island. Take a look at our progress! Many dive schools over the island, including Crystal, Bans, New Heaven, Blacktip and of course Big Blue have been working very hard for the last week to put these structures in the water. So come take a look at ours - it's just west of Navakid's buoyline!
