Over 100 endangered White’s Seahorses born at SEA LIFE Sydney Aquarium

Over 100 endangered White’s Seahorses have recently been born at SEA LIFE Sydney Aquarium - marking a successful start to the second year of the White’s Seahorse Conservation Breeding Program initiated by SEA LIFE Sydney Aquarium, Fisheries NSW and the University of Technology Sydney (UTS).

The herd of Seahorse babies each smaller than a grain of rice emerged from their father’s pouches in the final months of 2020.

Aquarium staff say the babies are growing nice and strong while their parents are keeping busy and expected to deliver more babies over the next few months. 

SEA LIFE Sydney Aquarium Aquarist and Seahorse Expert, Mitchell Brennan advised “we have over 100 White’s Seahorse babies and are expecting more. We took learnings from our first year of breeding and made changes to the facility, food source and their husbandry routine to develop a more streamlined and efficient program. We believe this may have contributed to such a positive start to the season.”

The White’s Seahorse Conservation Breeding Program launched in the second half of 2019 with a goal to determine a successful method to restore the population of the White’s Seahorse aka Sydney Seahorse which was declared endangered due to habitat loss. Divided into several stages, the program focuses on repopulating the species in the wild by, establishing new habitats in Sydney Harbour and returning them into the wild.

In its first year, 90 juvenile seahorses born into the program were released into Clifton Gardens to live in artificial habitats called Seahorse Hotels. The babies successfully survived their first stint in the harbour, with their growth and development closely monitored by aquarium, UTS Masters Research students and Fisheries divers. Success in this phase was realised when several of the release seahorse paired and mated with their wild counterparts.

As the conservation program progresses further into its second year, scientists and aquarium staff will build on last year and construct new upgraded Seahorse Hotels that will better facilitate the babies once they are introduced to the wild. SEA LIFE Sydney Aquarium, the Fisheries NSW, and University of Technology Sydney will also work together to source two new locations for these hotels in Sydney Harbour.

Dr. David Harasti, Senior Marine Scientist with DPI Fisheries, who has over a decade of experience working with the White’s Seahorse notes “we are very pleased with the progress of this conservation program for Australia’s only endangered seahorse. Seeing captive released animals still alive in the wild eight months after release and breeding with the local population is a fantastic initial result.”

UTS Professor of Marine Ecology, David Booth is supervising Masters Research students on this project and adds “the project so far has been an amazing opportunity for our students to get hands on training in understating issue of ecology and conservation of these unique creatures.”
