Pioneering Reef Restoration, Food Security, and Carbon Capture with Giant Clams

through in-shore mariculture and innovative marine science practices


The International Marine Science and Carbon Sequestration Foundation (IMARCS)

We are piloting in-shore mariculture projects in Japan to benefit life under the sea and on land. 


Our Mission

To pioneer innovative mariculture solutions that remove CO2 from the air, restore marine ecosystems, and strengthen local communities with measurable, quantifiable results.

Our Vision

A thriving and sustainable future where mariculture and marine science are a standard and well-known mechanism to mitigate climate change by permanently storing CO2 in calcifying organisms, while also providing sustainable food sources and creating more resilient communities in the process.

What we're about

Removal of carbon from the atmosphere
Replenishing reefs with needed species
Restoring marine ecosystems
Reviving coastal communities
Rethinking what is possible for our future

Our Project

Developing a novel in-shore giant clam grow out methodology.

Clam Mariculture

As our main avenue for direct carbon removal, food security, and threatened species preservation, we grow multiple species of giant clams.

We currently grow five species of giant clams:
  • Tridacna crocea
  • Tridacna derasa
  • Tridacna maxima
  • Tridacna squamosa
  • Tridacna noae


We are constantly working to correct misinformation in the marine science field, especially as it pertains to coral reefs. We also partner with local schools to provide tours for students, universities to offer internships, and other foundations to expand our impact. 

See our blog for the latest on our work helping to educate, elucidate, and inspire.

Clams provide food security, carbon sequestration, and natural water filtration...but they're now gone from largest areas of their natural range

By utilizing marine science and mariculture focused on these giant beauties, we can:

  • Preserve biodiversity: all giant clams species are threatened
  • Remove carbon: giant clams provide a quantifiable source of permanent carbon sequestration
  • Feed local communities: giant clams are a staple in many parts of Asia
  • Deter poachers: mariculture organisms can help meet demand for food and as decorative shells
  • Restore ecosystems: our long-term goal is to re-seed lost habitat ranges

Our Founder

My name is Gui Gui, and I'm from one of the Karen tribes. My family and I had to leave Myanmar as the military there is actively hunting and killing the Karen people, even though we are very peaceful. We escaped to Thailand, where I grew up. Now, I am in Japan, and I'm very happy to have started IMARCS and working with my amazing team!
