Indonesia's Central Java pilots closed-system vannamei farming ahead of 72,000-hectare northern coast pond revitalisation

The provincial government is coordinating with the Ministry of Marine Affairs and Fisheries to optimise inactive traditional ponds along Central Java's northern coastline.

Central Java province has harvested vannamei shrimp from a modern closed-system aquaculture facility in Semarang, using the pilot project to demonstrate production techniques ahead of a broader programme to revitalise approximately 72,000 hectares of traditional ponds along the province's northern coast.

The harvest took place at the Fish Hatchery and Aquaculture Centre within the Wijayakusuma Industrial Estate, managed by the Central Java Marine and Fisheries Agency. The 1,561-square-metre pond completed an approximately 82-day cultivation cycle producing around 1.3 tonnes of vannamei shrimp, averaging 60 shrimp per kilogram for domestic sale.

Endi Faiz Effendi, Head of the Central Java Marine and Fisheries Agency, said the facility applies a closed cultivation system suited to its industrial estate location, minimising external water intake while maintaining water quality through treatment with dolomite, chlorine and aeration.

The hatchery reported achieving approximately 72% of its annual regional revenue target in the first half of 2026. Central Java Governor Ahmad Luthfi called for the expansion of fish and shrimp hatchery centres across the province and urged greater support for farmers through quality seed production, cultivation guidance and marketing assistance.

The pond revitalisation programme, coordinated with the national Ministry of Marine Affairs and Fisheries, aims to bring inactive traditional ponds back into productive use and improve long-term aquaculture output across Central Java's northern coastline.
