Grouper Cultivation

Grouper Cultivation

In April to September 2004, we were engaged with Grouper cultivation together with PPKJBS (South Johor Farmers Organization) at their facility at Gelang Patah, Johor.

They imported some 10,000 fries of Grouper with the size of 0.5 inches from Bali and grow them up to 3.5~4 inches in raceway, thereafter transfer them to cages to grow them further.

Location: Gelang Patah, Johor
