Northern reefs record giant clam recovery

Vorovoro Island in Macuata has recorded a 100 per cent survival rate of giant clam seeds, marking a significant conservation success for the Ministry of Fisheries.

A ministry research team reported the findings following a monitoring mission focused on restoring giant clam populations.

Tridacna maxima seeds released in the area have shown rapid growth, now reaching three to four times their original size.

The team also observed strong biodiversity, including wild Tridacna crocea and healthy adult clams in protective cages.

Research officer Onisimo Tubuna said the site’s ideal biological conditions and a thriving coral ecosystem were key to the success.

“These results position Vorovoro as a leading example of effective marine conservation and long-term sustainability,” he said.

The team also monitored Galoa in Lekutu, Bua Province, where clams seeded more than a year ago showed a 63 per cent survival rate, with the remaining clams exhibiting strong growth and adapting well to their environment.

Researchers noted the presence of a healthy natural population of Tridacna crocea, reinforcing the site’s ecological suitability for reef restoration efforts.

Mr Tubuna said the results highlight the potential of these reefs to support both introduced and naturally occurring clams, indicating a resilient marine ecosystem.
