Fish farm Apollo Aquarium on Friday opened a $1 million plant to rear groupers at its land-based Lim Chu Kang farm in Singapore.

The 12-tank experimental system, which will rear 300kg to 400kg of fish in each tank, is a method to farm fish on land using high-tech water treatment.

Apollo Aquarium is possibly the second farm to rear fish this way. The first, a 1,400 sq m farm in Pasir Ris, rears more than a million sea-bass fingerlings each year for sale to other farms.

Farms such as these are helping to boost the productivity of Singapore’s food-fish farms.
