VIDEO: Over 1,200 Endangered Seahorses Released into Port Stephens Habitat

29 July 2025

newy.com.au – More than 1,200 endangered White’s seahorses have been released into the waters of Port Stephens, marking the largest release of the species ever undertaken globally. The juvenile seahorses, bred in captivity, were introduced into specially designed underwater structures known as “seahorse hotels” as well as nearby natural habitats including seagrass beds and endangered soft coral areas.

The release forms part of a broader recovery effort funded by the Australian Government’s Saving Native Species program and led by the NSW Department of Primary Industries and Regional Development. The initiative follows severe population declines of White’s seahorses over the past three years, largely due to extensive flooding along the east coast.

The seahorse hotels are made from metal that gradually breaks down in seawater and are decorated with biodegradable materials. As the metal degrades, sponges, corals and algae grow on the structures, transforming them into natural shelters for marine life. Over 400 local students assisted in constructing the habitats, gaining hands-on experience in conservation.

Federal Environment Minister Murray Watt said, “Unfortunately, the natural habitat of the White’s seahorse has been severely impacted over the years. That’s why both levels of Government are supporting the experts who are doing what’s needed to get this species back on track.”

NSW Minister for Agriculture and Regional NSW, Tara Moriarty, praised the collaborative efforts, stating, “The release of 1,200 White’s seahorses gives real hope for the future of this iconic species. The aquaculture breeding program, which commenced in February 2024, is a flagship example of how our Government is committed to leading recovery efforts for endangered species.”

Local representatives also welcomed the project. Federal Member for Paterson, Meryl Swanson, described the release as a “significant step forward in the recovery of Port Stephen’s White’s Seahorse population,” while State Member for Port Stephens, Kate Washington, noted the pride of the local community and student involvement in what she called a “world-leading program”.

Further releases are planned for later this year in Botany Bay in partnership with the Gamay Rangers, traditional custodians of the area.
