A Coral Transplantation with Postgraduate Udayana University

Article by Arthur Masse and pictures by Agung Bayu

On Friday the 29th of June, Nusa Dua Reef Foundation welcomes a group of around 40 people from the Postgraduate Program of Udayana University, Bali on Nusa Dua beach. This group included students in Environmental Sciences and Biology, lecturers and postgraduate office staffs, vice director and director. Were also present the coordinator of Master’s Degree in Biology study program and the coordinator of Master’s Degree in Ergonomy program.

After an opening speech from the Director of the Postgraduate, Dr. I Putu Gede Adiatmika, the Vice Director of the Student and Academic Affairs Mrs. Dr. Ida Ayu Astarini, and Pariama Hutasoit, Director of the Nusa Dua Reef Foundation, the coral transplantation took place.

Pariama Hutasoit teached the students, lectures and staffs how the coral transplantation works and how to make it the best way possible. Through different proceeds and techniques, everyone could learn the theory before going into the practice.

The goal of this activity was twice: For Nusa Dua Reef Foundation, to show the work they are doing and make people aware of what’s happening with the coral those days. For the students of the Udayana University, 3 interests. The first one was to get involved in coral reef rehabilitation in Bali and particularly in Nusa Dua. Then, the postgraduate’s students in University learned about coral ecosystem, so the goal was to increase their awareness and understanding on how vital the rehabilitation of coral and maintaining and healthy coastal ecosystem is and on how vital it is for the costal environment. Finally, this activity can give ideas for the master thesis the student have to work on in PhD.

The group transplanted coral pieces on about 10 structures. After this, the team from Nusa Dua Reef Foundation, with the help of Ida Ayu Astarini and Job Nico Subagio, a marine biologist, brought and installed the fresh new structures in the coral garden of Nusa Dua.

Having more and more people feeling involved in coral conservation and who want to know and see about the work the different NGO’s are doing is the key to increase awareness and change behavior about corals extinction, but it’s also a big motivation for those organizations to keep fighting for what they’re doing. This activity with Udayana University was very good and we look forward to see them again at Nusa Dua Reef Foundation.

Planting coral on artificial reef structures in some areas needs to find the best source of coral fragments. Two solutions are set up here in our coral garden at Nusa Dua waters, Bali. The first one is collecting from cultivation in some coral farms, and the second one is from natural habitat surrounding of coral garden. For the first option, we collect coral from the Bali Aquarium and local fishermen group’s coral farm at Serangan island, Denpasar, Bali, as well as from our coral nursery in Nusa Dua waters. Here, many differents species of hard corals are cultivated, and those corals are for export to some countries, especially Europe, USA, and Asia.

Once we collect those coral fragments, we must transplant them on the structures by using cable ties. This is the same for the coral which live in the natural habitat. We just have to cut some pieces from the ones colony who are already on the structures or from the ones living in natural habitat and then transplant it on the structures. No matter the origin of the coral, there is one common point: Once the coral is transplant on any structures or rocks, it has the ability to glue, develop itself, and grow. That means if you cut one piece, the coral doesn’t die immediately: If you re planting it, it will grow and start back living.

In these ways it seems easy to do it, but what take the most time is the maintenance: removing plastics, wastes, overfull algae’s that are staring on it and inhibit or slow their growth, etc. And hard coral doesn’t take one, two or five years to live and grow. Hard coral can live hundred years. A brain coral as sample just growth 1 cm per year, so if you find a big brain coral, you can count how old it can be. Other coral such as Acropora branching can grow faster, around 5-15 cm per year. The growth of coral is different, depending on the species, but mostly slow and take much longer, and that’s why we must make those coral gardens bigger and bigger.

Plastic Hurt Oceans But Not Only

Article by Arthur Masse

Recent studies show that the world’s plastic production is not going to stop growing. From 1.5 million of tons in 1950, it reaches the critical number of 322 million of tons in 2015. Even if the increase is stabilized since 2012 (around 3.4% per year), the average year increase since 1950 is 8.6%. Obviously if the developed countries are the ones consuming the most, the Asian area is today the world’s first producer of plastic with around 30%.

And on this amount of plastic consumption, according to a report from the Ellen Mc Arthur Foundation, eight million of tons of plastic are thrown to the ocean. An alarming number, as if every minute in the world a truck full of plastic is dumping it into the ocean. We already know for example that a huge waste plate exists in the north Pacific Ocean (called the plastic’s seventh continent), with a size of one third of the USA. This one shows in part how the amount of the plastic in the nature is critical. But what shows another study conducted by the Global Monitoring Center for Conservation and published in Marine Policy, is that the plastic will not only be present at the surface or in the low to mid depths of the oceans. Indeed, more than a half of waste under 6000 meters are plastics, with a disposable majority. And some plastics bags are even being found at places of more than 10000 meter deep.

Those plastics wastes are hurting and killing marine life, with two majors axes: The first one is that animals are eating these plastics or are stuck in it. Many examples exists and we can quote some very recent ones, as the whale found dead in Thailand because of having eat around 80 plastics bags. We can quote too the number of videos of animals stucked in nets as whales, whales sharks, dolphins, etc. But this is true for corals too. Here is the reverse: the plastic is locked in the coral, which stop his growth, be suffocated, and finally die. The second axe and not the more important is that lots of species stucked in plastics are transported through the oceans for years with the currents and are no more living in their usual area. This is a big danger for the marine ecosystem which loose some links of its food chain in some areas. If we don’t change our habits, according to the same report of the Ellen Mc Arthur, they will be more plastics than fishes in the ocean by 2050.

Finally, the plastic in the ocean can hurt us,humans, or is already doing it. Buy eating seafood, we are barely eating plastic. And this plastic is the one that has been thrown in the ocean. A study conducted by the Tokyo University of Agriculture and Technology has shown that 80% of Tokyo’s bay anchovies were containing micro plastics (plastic pieces usually separates for example by the wind, sun and currents in micro balls, all between 0.1 and 5 millimeters). And those anchovies are far to be the only fish species containing micro plastics. 114 species from every oceans all around the world are contaminated, and half of them finish in ours plates. But is there a real risk for us, humans?

It is very difficult to determinate today, because those micro plastics are also present in tap water, clothes, cosmetics or even air. There is nearly no places in the world without micro plastics. For sure they are dangerous for the fishes’ health, at a point that some governments think so for the human one. They are present in every link of the food chain, but those really small pieces can penetrate into the cells and go into the different muscles and organs. Different research are on the way, but scientist are more scared about their impact in the human body than their safety for the human health.

That’s why today, changing our behaviors and minds about plastics is not only for the differents ecosystems, but for our health too.


Coral Transplantation in Celebrating 35th Anniversary of Marsh in Indonesia

Nusa Dua – PT Marsh Indonesia, in celebrating 35th anniversary the company, conducted a coral transplantation on spider’s artificial reef structure of Mars Accelerated Coral Reefs Rehabilitation System (MARRS). This activity has been done in conjunction to Corporate Training & Team Building 2018 at Taman Bhagawan, Nusa Dua Bali on March 4, 2018.

Alistair Stewart Fraser-Hawkins, the President Director of PT Marsh Indonesia in his speech said that the world’s coral reefs are threaten by human activities, such as over-fishing and destructive fishing, coastal development, marine-based pollution and damage, and agricultural runoff and also climate change. “This coral transplantation as part of our effort to save coral reefs in the world,” he said.

Coral reefs, the “rain forests of the sea” are among the most biologically rich and productive ecosystems on earth. They are supply a wide range of important benefits to communities in the world, provide valuable ecosystem benefits to millions of coastal people, important sources of food and income, serve as nurseries for commercial fish species, attract divers and snorkelers from around the world, generate the sand on tourist beaches, and protect shorelines from the ravages of storms.

With the tag campaign #SAVECORALREEFS, a board of directors together with 135 staffs of PT Marsh Indonesia transplanted about 135 coral fragments on 13 spider’s structures.  The Nusa Dua Reef Foundation teamwork then took it with a boat to the location of Coral Garden at Nusa Dua waters for its underwater installation.

Spider’s is design as (MARRS) in which the corals are attached, to fill the gap between the remaining natural corals. It stabilizes coral reefs, limits coral ruins and provides the substrate for recovery habitat, as well as natural enhancement of coral biodiversity. Fish can return quickly to rehabilitated areas, restore ecosystem balance, control algae and create the basis for sustainable fisheries in the future.

Our greatest thank to PT Marsh Indonesia for taking part in the coral reefs conservation of Nusa Dua. Thank you to Ego Global Network and Apollo Dive & Watersport for their support in this project.

Coral Transplantation, CSR Program of PT Angkasa Pura I (Persero)


Nusa Dua – Recently, together with stakeholders, we conducted coral transplantation on 60 spider’s artificial reefs structures donated by PT Angkasa Pura I, I Gusti Ngurah Rai Airport Bali, on Thursday (18/01/2018) in Coral Garden, Nusa Dua waters.

This activity was attended by a number of parties such as representatives of PT Angkasa Pura I (Persero) I Gusti Ngurah Rai Airport, Denpasar Regional Office of Coastal and Marine Management of Ministry Fisheries and Marine Affair (BPSPL Denpasar), ITDC, Diver Peduli Laut Nusa Dua, Pokmaswas Yasa Segara Bengiat, and others. Completing transplantation more than 700 corals fragments on 60 spider’s structures becomes a tough task for less than 10 volunteers to ensure transplantation follows a structural model. All the structures with corals on it have installed in underwater of Coral Garden, Nusa Dua.

To ensure corals survive and grow and structures were good installed and stable on seabed, Nusa Dua Reef Foundation teamwork conducted monitoring and maintenance every week. At the first week, the progress was great, 98%, corals have been live. Meanwhile, the rest of the coral have loosed and died. After two months, the development of living corals is increasing and many fishes around it. Only need a little cleaning algae which attached to corals and structures, the rest almost all living corals.

Our special thanks to PT Angkasa Pura I (Persero) I Gusti Ngurah Rai Airport for their donation. Thank you to ITDC, BPSPL Denpasar, Diver Peduli Laut Nusa Dua and all our volunteers for the great support.

Coral Transplantation with ITDC in Coral Garden, The Nusa Dua

Nusa Dua – Indonesia Tourism Development Corporation (ITDC) conducted a coral transplantation as an effort to support the conservation of coastal and marine ecosystems in Bali. Coral transplantation was carried out at The Nusa Dua beach on Friday (15/12), involving staffs and volunteers. A number of foreign tourists who participated in watching this activity on the beach gave appreciation.

The goal of coral transplantation are to transplant corals in the shallow waters of The Nusa Dua, restore damaged reef ecosystems, raise awareness among people about the importance of coral reefs, and as a part of the 44th ITDC Anniversary celebrations.
Various hard corals from genus acropora, montipora, porites, stylopora and favites have been transplanted on the spider’s web structure, using cables tie to fix on it. The corals transplant then placed at the Coral Garden, in the depth of 3 meters (highest tide) and 1.20 meters (low tide). Coral Garden location is about 150 meters from The St. Regis Bali Resort beach. It’s developed by Nusa Dua Reef Foundation in mid-2016 as an effort to recover dead corals post global coral bleaching event and to rehabilitate coral reefs ecosystems which destroyed by coral mining practices for building material in the past decades by local communities, long before The Nusa Dua resorts area was built. Coral mining was stop due to establishment of ITDC in 1973 and the construction of hotels began, but it has left massive damaged of coral reef ecosystems in lagoon areas until now.

The Nusa Dua coastal area is important habitat for coral reefs and seagrass beds. Both these ecosystems play important role, ecologically and economically. Coral reefs are habitat of marine life biota, source of food, coastal protection and big wave barrier, source of medicine, industrial raw material and jewelry, as well as tourism object. This coral transplant effort is expected to restore some damaged coral reef ecosystem and is expected to become a new tourism object within the Nusa Dua area.

Coral transplantation is collaboration Nusa Dua Reef Foundation with ITDC and Mars Sustainable Solution (part of Mars Syimbioscience).


The good progress of coral transplantation on 43 spider’s web structures at a pilot project of Coral Garden, Nusa Dua, Bali after a year. Some corals died, but the growth of live corals with its beautiful color prove that corals can grow well at the Garden. As a rehabilitation effort, Coral Garden needs to be expanded by scale-up the structure of spider webs and transplant more corals. Need support funding from multi parties, especially hotels management around Nusa Dua.

Nov. 17, 2017

Beautiful on the surface, but dirty inside. That’s the ironic condition of the Nusa Dua coast … the beach of this luxury hotel area always looks clean on the surface, but look to the sea, a lot of plastic waste, especially during the East wind season. The beach cleaning officer just cleans up trash around the beach, not at sea. Is it because it is considered a common property area so no one wants to take responsibility for cleaning it? Plastic waste not only threatens corals, but other marine life animals. Save our ocean!

Coral Transplantation to Saving Coral Reefs


Nusa Dua Reef Foundation initiated a coral rehabilitation project to restore degraded reefs around intertidal area of The Nusa Dua, located in Southeast coast of Bali Island. A massive coral mining in past decades has occurred, causing coral reefs disappear, while many corals recruitment has died as impact of mass coral bleaching event in 2016. Coral bleaching and associated mortality not only have negative impacts on coral communities, but they also impact fish communities and the human communities that depend on coral reefs and associated fisheries for livelihoods and well-being.

A small pilot project has started on 20th July 2016 with 50 corals fragment taken from coral farming, generally Acropora sp, Montipora sp and Galaxea. Coral fragments have been transplanted on three spider’s structure artificial reefs and dead corals. Two months later, on September 2016, more 200 corals fragment have been transplanted on 40 spider’s structure. Spider’s structure are metal structures that have been designed, built, and secured to the reef. The technology is based on a simple structure that does not shade the corals very much or impede water flow around them, enabling them to thrive.

After a year, many corals showed growth well. Some corals died due to stress condition before being transplanted and couldn’t survive with new environments. The growing corals transplantation progress shows that water conditions support new corals. It certainly gives hope for this project for scale-up in the future.

NDRF now is calling for support this project.  A crowd funding platform has launching recently through www.ekosea.com to support this project and to give individuals, communities and companies the opportunity to engage directly in saving coral reefs by becoming adopters.

Illegal Trade in Ornamental Corals


  Since 2016, Nusa Dua Reef Foundation (NDRF) has collaboration with Regional Center of Fish Quarantine, Quality Control (BKIPM) Denpasar for conserve corals confiscated from illegal trade in ornamental corals. NDRF as a conservation organization has been trusted to release in the wild and manage its coral reefs species for conservation, education and tourism purposes.

  Recently we received about 800 corals were taken from natural habitat, without official documents and its mean illegal trade. These corals have been harvested from the wild in the coral reefs area around Sumbawa Island, NTB and in on the way transported to Banyuwangi, East Java, where the coral exporter company runs its business there. Its transport was stop at Gilimanuk port, Bali by BKIPM on 4th July 2017 and confiscated, then taken to Mengiat Beach at night, followed by the official delivery to NDRF on 5th July 2017.

  Many corals have dead because of stress and passing long journey during transport from the wild to the shelter. The remaining corals were still alive but yet in the very stress condition.  Those corals have been harvested, separated from the main colony and need to save as soon as possible.  Immediate rescue action was carried out by NDRF in collaboration with Coral Reef Aquaculture Group of Pesona Bahari and CV Agung, by transferring coral into the sea. The corals were placed carefully on the nursery place, monitor it regularly, until it is healthy enough to be returned to the wild.

  Corals harvesting from natural habitat has been strictly regulated by Indonesian government by issuing quotas. According to CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora), corals are on the list of Appendix II. It means that their international trade have to be closely controlled to avoid over exploitation, and to guarantee that trade will not be detrimental to the survival of the species in the wild. To minimize coral trade which is harvested from the natural habitat, coral transplantation is an alternative way, but some regulations should be applied to guarantee sustainability of coral reef ecosystem. But yet, high demand for live coral for ornamental has been triggered corals harvesting from natural habitat, especially for certain species such as Cynarina lacrymalis, Catalaphyllia jardiney, Alveopora, and others, encourage overexploitation. Overexploitation of these species could result in severe localized extirpations.

  In Indonesia, the exploitation of live corals for export has been started almost 40 years. Indonesia government regulates the number of colonies that can be exported each year in accordance to the coral species and the origin of coral from the province that is allowed location for harvesting. Officially there are 2 institutions responsible for this regulation, that are Management Authority (MA) given to Directorate General of Forest Protection and Nature Conservation, Department of Environment and Forestry and Scientific Authority (SA) is given to Indonesian Institute of Sciences (LIPI).

  Until now Indonesia is listed as the largest exporter ornamental corals in the world. Generally, these ornamental corals are exported to Europe and the United States. Of the 569 existing corals species in Indonesia, currently traded as many as 81 species (14%). Live corals traded are coral reefs species that have beautiful colours, exotic colonies and exotic tentacles, such as Acropora formosa, Alveopora spongiosa, Blastomussa wellsi, Catalaphyllia jardinei, Cynarina lacrymalis Echinopora lamellose, Euphyllia divisa, Favites chinensis, Galaxea fascicularis, Scolymia Vitiensis, and others.

  The size of the traded corals ranges from 10 – 25 Cm and is generally 15 cm in size. Other countries that still trade live corals from nature include Australia, Fiji, Malaysia, Vietnam, Ghana, Solomon, Vanuatu, Israel. The value of Indonesian ornamental coral trade ranges between US $ 6.2 million.

  Yes, trade in ornamental coral reef wildlife supports a multi-million-dollar industry but in some places threatens vulnerable coral reef species and ecosystems due to unsustainable practices and lack of effective regulation. Further conservation and management strategies of ornamental coral reefs wildlife is a must.
