Local authorities are drafting a resolution to support the transition to HDPE and FRP cages as part of efforts to modernise marine aquaculture and improve resilience to storms and climate change.
The scheme will apply to individuals, cooperatives and other legally established organisations farming fish in designated marine aquaculture zones.
To qualify, farms must operate within approved aquaculture areas, use cages made from the new materials and must not have previously received government support for cage purchases.
Under the proposal, farmers operating within three nautical miles of the coast would receive a one-off subsidy covering 50 per cent of the cost of new cages, capped at VND 282 million (around USD 10,700) per individual or organisation member during the 2026-2027 period.
For farms located three to six nautical miles offshore, the subsidy would rise to 70 per cent, with a maximum of VND 395 million (around USD 15,000).
During the 2028-2029 phase, the support level would fall to 30 per cent, capped at VND 170 million (around USD 6,500), for eligible farms operating within six nautical miles of the coast.
The programme aims to improve disaster resilience, protect livelihoods and promote sustainable offshore aquaculture.
