Semakau fish farm finally to be removed?

Said to be the largest in Singapore, this fish farm near Pulau Semakau is finally going to be dismantled and removed. More than three years after the farm was abandoned.

Barramundi Group's abandoned fish farm is located very close to natural mangroves, reefs and seagrass meadows at Pulau Semakau North. We have checked it out every time we survey there. On our last survey in Apr 2026, the farm remains totally abandoned and in a state of decay. Since our Apr 2025 survey, the big barge with equipment and supplies, and floating dorm for workers were gone. Cages were falling apart and derelict small boats nearby. 

In Jul 2023, it was reported that Barramundi Group will stop stocking its sites off Pulau Semakau, Pulau Senang and St John’s Island until “an efficacious vaccine is available” against the scale drop disease virus (SDDV). SDDV was first formally described in Singapore farmed fish in 2011 and can kill more than half of the barramundi raised in a cage. The virus has caused “significant mortalities and financial losses” for Barramundi Group's Singapore operations, which recorded a loss of $31.9 million for FY2022.

An MPA notice announced that works will be conducted end of the year, to dismantle the farm.
