• The Philippines is set to host Southeast Asia’s first coral larvae cryobank at the University of the Philippines Marine Science Institute.
• Aim: freeze and preserve coral larvae to restore damaged reefs, safeguard genetic diversity, and support long-term reef resilience.

HIGHLIGHTS

Importance of the Coral Triangle

• Covers 5.7 million sq. km across Indonesia, Malaysia, Papua New Guinea, Philippines, Solomon Islands, Timor-Leste.
• Richest marine ecosystem: >75% of world’s coral species, 1/3 of reef fish, six of seven marine turtle species, vast mangroves.
• Supports food security and livelihoods of 120+ million people.
• Threats: climate change, coral bleaching, habitat loss, destructive fishing, pollution.
• Between 2009–2018, 14% of corals lost; 70–90% could vanish by 2050 if global warming exceeds 1.5°C.

Cryobank Initiative

• Freezes coral larvae (“seeds” of corals) at very low temperatures for later use.
• Part of a regional network linking Philippines, Taiwan, Indonesia, Malaysia, Thailand.
• Supported by Coral Research & Development Accelerator Platform and Marine Environment and Resources Foundation.

Cryopreservation Technique

• Uses vitrification: larvae exposed to protective solutions, then plunged into liquid nitrogen at –196°C.
• Rapid freezing prevents ice crystal formation, preserving fragile cells.
• Revival uses laser thawing, followed by gradual rehydration and monitoring for life signs.

Species and Research Strategy

• Initial focus on model species like Pocillopora, Acropora, Galaxia.
• Preservation not limited to endangered species; all coral species considered at risk.
• Coral symbionts (Symbiodiniaceae) also preserved, crucial for reef survival.

Significance & Long-Term Goals

• Acts as a genetic insurance policy against reef collapse.
• Strengthens ecosystem resilience, research, and restoration efforts.
• Encourages regional collaboration among scientists, governments, universities, and local communities.
• Integrates community awareness, as local livelihoods depend on healthy reefs
