What do we do?

Perry Institute for Marine Science leads ocean research, conservation and education in The Bahamas and Caribbean.

Coral Restoration

The Bahamas, Aruba, and St. Lucia

Coral restoration focuses on propagating coral stocks within nurseries – imagine underwater coral farms, where coral fragments are then outplanted onto degraded reefs which helps increase the growth of the reef.

Coral nurseries

Coral nurseries are habitats dedicated to foster coral growth. Many nurseries have “coral trees” where the fragments are suspended like Christmas tree ornaments. Studies have shown that the suspending of coral fragments in the water column accelerates their growth drastically, while also protecting them from excess sedimentation on the ocean floor.

Coral nurseries are

Natural spawning

Coral spawning is an annual phenomenon during which corals of the same species synchronize the release of sperm and eggs (gametes) into the water column over several days following the full moon 🌚. The little white balls that look like snow are coral gametes! Natural spawning is a great sign of healthy corals, as they don't spawn when they are sick or stressed.

Coral Science

Coral reef science can drastically help future coral generations survive, by choosing more heat-resistant genotypes, or conducting experiments to maximize coral reef survival. PIMS focuses their research on managing, conserving and restoring marine ecosystems with scientists, resource managers, NGO’s, local businesses, governments, and community members.

Coral Education

Our community conservation program seeks to provide the tools, trainings, and experiences to foster a greater conservation ethic across The Bahamas and the Caribbean. By growing local capacity in marine conservation, we hope to create more pathways to conservation careers and empower the next generation of ocean stewards.

There are three main areas in which coral conservation organizations usually focus their resources on: coral restoration, coral science & research and last but not least, coral education. This is a breakdown for how this organization distributes their funds.
