Central Java Government Proves Closed System Technology Success in Shrimp Harvest

Through technological engineering, a 1,561 square metre pond has not only succeeded in producing high-quality shrimp but has also become a pilot model for modern pond revitalisation along the Pantura (North Coast) region. Head of the Central Java Marine and Fisheries Service, Endi Fa Efendi, stated that the harvest took place in Plot B3 of the Loka PBI Tugu. From a cultivation period of approximately 82 days, the vaname shrimp production target reached 1.3 tonnes, with a size of about 60 shrimp per kilogram. Endi explained that the pond applies a closed system, as it is located in an industrial area, thus water usage is minimised. “We use very little water from outside, then we treat it with dolomite, chlorine, and aeration before using it for cultivation,” he said in a written statement on Monday. Endi added that this harvest is marketed to meet local needs at a price of around Rp60,000 per kilogram. Furthermore, Loka PBI Tugu continues to show positive performance with the realisation of locally generated revenue (PAD) reaching approximately 72 percent of the annual target by the first semester of 2026. On the occasion, Central Java Governor Ahmad Luthfi requested the Marine and Fisheries Service to boost fish and shrimp hatchery centres. According to him, hatcheries are more beneficial for the community because production costs are cheaper, business turnover is faster, and they can support food security. Therefore, Luthfi added that government-owned fisheries centres must become superior hatchery hubs that can be utilised by farmers in various regions, ensuring the public no longer struggles to obtain quality seeds. He also requested all experts and extension officers within the Marine and Fisheries Service to more actively assist the community, from seed provision and cultivation guidance to product marketing. “So the community won’t have to look elsewhere. That way, our service is truly beneficial for the people,” he said. Luthfi stated that the fisheries sector is a crucial part of supporting the national food self-sufficiency programme. Central Java has a coastline stretching across 17 regencies/cities, but most of its pond areas are still managed traditionally and need revitalisation. He revealed that he has coordinated with the Minister of Marine Affairs and Fisheries regarding the revitalisation plan for ponds on the North Coast of Central Java, which covers approximately 72,000 hectares. “In the near future, the Minister of Marine Affairs and Fisheries will provide full backing for our North Coast region. The principle is that it will be immediately overseen so that non-functioning ponds can be put back into operation as soon as possible,” he said.
