The Marine Aquaculture Centre (MAC) is located on St John's Island in the open southern waters of Singapore.
As the R&D hub for tropical marine aquaculture, the Marine Aquaculture Centre (MAC) plays a crucial role in transforming Singapore's agri-food industry.
For instance, MAC conducts R&D on large-scale hatchery production technology and fish nutrition (e.g. fish feed) which are more nutritious and, at the same time, environmentally sustainable. Local hatcheries have since adopted MAC’s live-feed production and hatchery protocols for their fry production.
Besides conducting its own R&D, MAC also partners various Research Institutes (e.g. Temasek Life Sciences Laboratory and Tropical Futures Institute) and Institutes of Higher Learning in Singapore to drive innovation and conduct cutting-edge tropical marine aquaculture research.
MAC also serves as a venue for aqua-tech companies to test-bed their technology to enhance tropical marine aquaculture practices.
MAC supports local R&D efforts with its expertise in crucial areas of fish husbandry such as breeding, live feed, hatchery production, and fish diet formulations.
Local researchers have access to facilities purpose-built for aquaculture research at the MAC. They include replicated tank systems and incubator spaces, which are ideal for the commercial test-bedding of R&D outcomes.

Local researchers also have access to key aquaculture research and feed production resources, including eggs, larvae, rotifers, and microalgae.

MAC collaborated with Temasek Life Sciences Laboratory to develop the Asian seabass selective breeding programme, where brood stock (fish selected specifically for breeding) was meticulously selected using aquaculture genomic tools.
The genomic tools identified fish with desirable traits for breeding (e.g. faster growth rate, higher disease resistance and omega-3 fatty acid content).
As the brood stock produced subsequent generations of offsprings, the programme gradually led to a lineage of fish that inherited and accentuated these desirable traits, without the use of genetic modification. These fast-growing, disease-resistant fingerlings have higher survival rates, increasing farm yields and giving local fish farmers a productivity boost.
To shift local hatcheries from large outdoor ponds to high-capacity indoor facilities that use only a fraction of the size, MAC developed an intensive indoor hatchery that features a Recirculating Aquaculture System (RAS) – a technology that local fish farmers can adopt for indoor, large-scale, closed-loop fish production.
MAC conducts hatchery R&D that leads to technology and sustainable farming practices that local fish farms can adopt to increase their production yield and quality.
There are multiple benefits to this system e.g. the recycling of clean water saves resources and minimises waste discharge, and the contained indoor environment ensures that fishes are not exposed to harmful elements and can grow in a controlled environment. With this technology, fish farmers can potentially improve fish fry survival with better biosecurity measures and intensify production using less space.
Aside from R&D, MAC also provides technical advice to help local farms adopt sustainable farming practices and technology.
This includes advising farms on setting up live feed cultures and hatcheries, developing protocols for hormone injections, and using fish breeding techniques to boost yield.
Farmers can seek these advisory services through the SFA Feedback Form.
While MAC is not available for public tours or walk-in visitors, it offers Learning Journeys for students studying aquaculture to enhance their learning experience. These visits are available once a month, lasting 1.5hrs each for a group of maximum 20 pax. To book, apply here.
