Coral Farming

Why Coral Farming Matters

Coral reefs are essential to marine biodiversity, coastal protection, and local livelihoods, but they’re under increasing threat from climate change, pollution, and unsustainable tourism. Our coral farming efforts help:

  • Rebuild reef structure and biodiversity
  • Support fish populations and marine life
  • Strengthen coastal resilience
  • Engage and educate local communities
  • Promote sustainable tourism in the Gili Islands and North Lombok

Our Impact and Goals

Since launching the farm in 2019, we’ve successfully grown and replanted around 600 mature corals onto degraded reef areas. Over the next few years, we aim to double our impact, expanding the farm and increasing our output to 1,200 adult corals annually. This growth will allow us to restore larger reef sections and strengthen ecosystem resilience across the region.

Our Method

Sustainable coral farming is the practice of farming using principles of ecology; the study of relationships between organisms and their environment. It’s all about farming the right species in the right environment.

Our coral nursery uses specially designed tables where one side holds a mother colony and the other side hosts coral babies; we micro-fragment the mother colony to create new babies, grow them until they’re ready, then transplant them onto the natural reef, repeating the cycle to sustainably and efficiently produce healthy coral.

Micro-fragmentation

Mother colonies are cut into fragments to grow coral babies.

Coral babies are plugged into the table next to the mother colonies.

We track coral health, growth, and survival rates.

Replanting

Once mature, corals are transplanted to selected reef restoration sites.

Community Involvement

Our coral farming program is deeply rooted in education and collaboration.

We involve:

  • University interns from the University of Mataram in hands-on coral restoration
  • Visitors and volunteers through our Discover Coral snorkeling course, where participants plant their own coral fragment and learn about reef ecology

Support Coral Restoration

Every coral we plant is a step toward a healthier ocean.

Together, we can help the reef recover, one coral at a time.

What is BRUV – Baited Remote Underwater Video method?

A camera is placed on the seafloor with bait positioned in front. It records fish that come to investigate over a set time. Footage is reviewed later to identify species and behavior. It’s a passive method like setting a camera trap for marine life.

In short: BRUV = film fish attracted to bait, then analyze the video later.

What is UVC – Underwater Visual Census method?

Divers swim along a transect line and visually record all fish seen within a defined area. They note species, size, and numbers during the dive. It’s a live fish count. Like taking attendance in a moving classroom.

In short: UVC = spot and count fish by eye while swimming the transect.

×
What is Belt Transect method?

A measuring tape is laid out along the reef. In our case divers count all visible invertebrates (e.g. sea cucumbers, starfish) within a set belt width usually 1 or 2 meters. They record species and numbers while swimming slowly along the line. It’s a wide-area visual count like sweeping a corridor for invertebrates.

In short: Belt = count all invertebrates within a set zone along the tape.

×
What is 3D Coral Monitoring method?

Divers take multiple photos of coral structures from different angles. Photos are processed using software to build a 3D model of the coral. This model shows shape, size, and changes over time. It’s like creating a digital twin of the coral to track its growth.

In short: 3D = capture coral from all sides, then build a model to monitor changes.

What is UPT – Underwater Photo Transect method?

A measuring tape is also laid out along the reef. Instead of recording points manually, divers take overlapping photos along the line. These images are later analyzed on a computer to assess coverage and species. It’s a visual capture method like scanning the reef with a camera for later analysis.

In short: UPT = record the whole transect with photos, then analyze later.

What is PIT – Point Intercept Transect method?

A measuring tape is laid out along the reef. Divers record what’s directly under specific points at fixed intervals (e.g. every 10 cm). It’s a manual, visual sampling method. Like checking what’s beneath each tick mark on a ruler. Data is written down underwater, point by point.

In short: PIT = record what’s under each point by eye, underwater.
