SINGAPORE –Singapore’s first urban fish farm in a container was launched on Nov 19 as part of an initiative to support local urban farmers and help the country reach its “30 by 30” food goal of producing 30 per cent of its food needs domestically by 2030.

The container fish farm is located in Tampines Street 11, next to the Tampines Round Market and Food Centre, and residents can look forward to enjoying the popular jade perch, a fish delicacy, after the first harvest in four to six months. 

Inside the shipping container, set up close to Tampines Town Council, are tanks housing jade perch that will be market-ready when they grow to about 500g to 600g.

The Tampines Round Market and Food Centre Merchants’ Association will be collaborating with local fishmongers to sell the jade perch, which can fetch up to $38 per kilogram.

Fish will be sold to fishmongers at cost price for this community project.

Speaking at the launch, Minister for Social and Family Development and Second Minister for Health Masagos Zulkifli, who is anchor minister for Tampines GRC, said: “The Tampines community is already showing strong support for the container fish farm project, not only from residents but businesses as well. We have received numerous applications from the public offering to assist with the container farm.”

Mr Masagos officiated the launch along with three other Tampines GRC MPs – Senior Minister of State for Sustainability and the Environment Koh Poh Koon, Mayor of North East District Desmond Choo and Senior Parliamentary Secretary for Sustainability and the Environment Baey Yam Keng.

He said Tampines is actively supporting local farms’ projects by identifying underutilised spaces where climate-resilient and resource-efficient urban farming methods can be tested and implemented.

Successful partnerships have resulted in projects like a tilapia fish farm in Tampines Park and a rooftop vegetable farm at a multi-storey carpark.

The two partners behind the container fish farm, aquaculture company Aqualita Ecotechnology and Tampines Town Council, are looking to gauge consumers’ interest in fish grown in the container fish farm.

A spin-off company from Temasek Life Sciences Laboratory (TLL), Aqualita engineered the containerised fish farm system with some components and technologies owned by TLL.

Aqualita is also looking to further understand the health of jade perch, particularly its nutritional needs, said the start-up’s director of technology Goh Chin Heng.

In particular, the project aims to develop feed to hasten the growth of jade perch from six months to five months – or even one month.

Said Mr Goh: “Jade perch is actually an omnivore – not a carnivore or herbivore. But many farms are using carnivore feed for the fish, and they end up with… a lot of oil deposits in the abdominal region.

“Similar to humans... the fish can also become ‘obese’, and may develop fatty liver that affects their health.

“Abdominal fat also adds to the weight of the fish, but it’s something that will typically be thrown away during processing and ends up in the waste bin.”

Apart from jade perch, five other species of fish have been shortlisted for farming in this recirculating aquaculture system – barramundi, red snapper, hybrid grouper, tilapia and murray cod.

The maximum stocking density, or the highest number of fish that can be in the containerised fish farm at any one time, varies according to the species due to differences in behaviour.

For instance, if the same number of barramundi and groupers are housed in the tank, injuries such as skin abrasions will be more common in the groupers.

This is because barramundi are more active swimmers than groupers, raising the incidence of fighting in enclosed spaces, said Mr Goh, who holds a degree in zoology.

A recirculating aquaculture system, such as the one used in the Tampines container farm, reuses water to grow fish under controlled environmental conditions within 15 sq m.

About the size of a bedroom in a Housing Board flat, the container fish farm is 25 per cent more productive than traditional farming methods.

Beyond the efficient production of fresh fish, the containerised farm will offer other benefits for the community, such as creating employment opportunities or space for educational activities, Tampines Town Council and Aqualita said.

A part-time worker from Tampines has been recruited to work at the fish farm for two hours each day, but the container will be locked outside operational activities to ensure the security of the fish.

Apart from working with schools to explore the use of the container fish farm for educational activities, Aqualita and the Tampines Town Council are also working with the People’s Association to donate fish bento sets to welfare organisations in the area on a regular basis.
