TAIPEI (Taiwan News) — A seagrass restoration project in Penghu County is restoring marine habitats, bringing back fish, and increasing blue carbon storage, Business Today reported.
The project is led by Business Today’s “Project Blue” initiative, in cooperation with the Penghu Fishery Research Center, National Taiwan University, corporate partners, local communities, and other groups. It focuses on rebuilding seagrass beds, which provide key habitats for marine life and act as natural carbon sinks.
In 2025, the team transplanted about 2,400 seagrass shoots in waters off Tongliang. The plants grew quickly within just over a month, expanding the restored area and attracting marine life back.
At least 14 fish species have been recorded in areas that previously showed little activity. Researchers said the return of juvenile and small reef fish is a clear sign the ecosystem is recovering.
Local fishers said marine resources have declined for years due to overdevelopment and climate change. They said the loss of seagrass reduced breeding grounds and led to smaller catches.
To improve survival rates, the team developed a “covering method,” a protective technique that shields young seagrass from currents and burrowing organisms. The method stabilizes plants during the first 14 days and helps roots anchor in the seabed.
The project has also expanded through a seagrass nursery built in a converted fishpond. The nursery has grown from about 0.5 square meters to more than 400 square meters and can now produce millions of seedlings each year.
Experts said seagrass ecosystems play an important role in blue carbon, capturing and storing carbon dioxide in coastal environments. Taiwan’s seagrass beds and similar ecosystems are estimated to absorb up to 470,000 tonnes of carbon annually, per Business Today.
Officials said new ways to measure blue carbon have recently been approved. They said this could encourage businesses to invest in restoration projects as part of environmental, social, and governance initiatives.
Researchers are also exploring new uses for seagrass, including compounds that may help fight fish diseases or support immune responses in aquaculture. These studies aim to expand its value beyond ecosystem restoration.
Education is another focus of the project, with programs designed to involve students and raise awareness about marine conservation. Organizers said long-term success will depend on public participation and environmental education.
