HONG KONG’S OCEAN IS UNDER PRESSURE

Coastal development, overfishing, intense marine traffic, and marine pollution are putting our ocean ecosystem at risk.

HONG KONG’S OCEAN IS UNDER PRESSURE HONG KONG’S OCEAN IS UNDER PRESSURE HONG KONG’S OCEAN IS UNDER PRESSURE

At popular sites like Sharp Island, overwhelming recreational use is now causing direct damage to fragile coral reefs. Visitors stepping on coral, anchoring boats in sensitive areas, and removing marine life can destroy ecosystems that take years to recover — or may never fully return.

If we don’t act now, we risk losing these ecosystems.

TAKING ACTIONS WHERE IT MATTERS MOST

WWF-Hong Kong is working at the frontline of marine conservation — addressing not just environmental damage, but the root causes behind it. At priority sites like Sharp Island and across Hong Kong waters, WWF brings together science, policy, and community action to create lasting solutions.

Science & Monitoring

Advocating for marine protected areas and better ocean governance across Hong Kong.

REAL IMPACT ON THE GROUND

At Sharp Island, education and on-site guidance have already helped reduce harmful behaviours and promote sustainable enjoyment of the ocean.

BUT MORE MUST BE DONE

Despite progress, threats to Hong Kong’s marine ecosystems continue to grow. We must now scale up efforts to ensure long-term protection and recovery. WWF-Hong Kong are calling the society to focus collective conservation efforts especially at 5 priority sites, namely Shui Hau, Tolo Harbour and Channel, Sharp Island and Inner Port Shelter, the Ninepin Group, and Pak Nai.

Ocean Conservation Priority Sites

Ocean Conservation Priority Sites
Shui Hau
Shui Hau
hosts a mosaic of interconnected ecosystems that together supports over 600 species, including 84 of conservation importance. Its sandflat is a unique landscape in Hong Kong and is a vital spawning and nursery ground for the endangered Chinese Horseshoe Crab.
Pak Nai
Pak Nai
has a wide range of habitats, from intertidal mudflats, mangroves to seagrass meadows. Historically, it is an important site for traditional benthic oyster farming. Pak Nai is also one of the last habitats for Horseshoe crabs in Hong Kong.
Tolo Harbour and Channel
Tolo Harbour and Channel
is home to a quarter of Hong Kong’s marine species, including the endangered Hong Kong grouper. It is also an important nursing ground for fishes.
Sharp Island
Sharp Island
is one of the most popular dive sites for scuba divers and snorkellers. Sharp Island North has the third highest coral coverage amongst the 36 Hong Kong Reef Check survey sites in 2025. Inner port shelter, where the Sharp Island is located, has a diverse marine life – Over 300 marine fish species and 46 hard coral species can be found here!
The Ninepin Group
The Ninepin Group
has one of the largest communities of soft corals and Gorgonian species thriving at the depth reaching 30m, while in the shallow waters, there is a high coverage of Staghorn corals, providing habitat for over 260 species of fish.

YOUR DONATION CAN HELP:

Expand Marine Protected Areas (MPAs)
Well-designed and well-managed MPAs safeguard high-value habitats, rebuild fish populations and enhance climate resilience.
Apply Other Effective area-based Conservation Measures (OECMs)
Support conservation beyond statutory protected areas that deliver long-term ecological benefits.
Restore Habitats
Revitalise damaged ecosystems such as corals, seagrass meadows and other key functional habitats as nature-based solution to enhance biodiversity, support fisheries recovery and strengthen coastal resilience.
Harness Smart Technologies
Anchoring technology as an enabler of ocean governance, to support place-based management that strengthens the observe-analyse-respond-adapt cycle, while enabling conservation action to be scaled, replicated and delivered at speed.
