Super-Intensive Shrimp Farm


Bhakty Baramuli, the owner of a small shrimp farm in western Sulawesi, who stocks Penaeus vannamei at densities from 500 to 1,000 (PL-10/m2) gets harvests as high as 28 metric tons per crop, which includes three partial harvest.   His 3,000 m2 concrete ponds are almost 3 meters deep, although they are only filled to the 2.2 meter mark.  The ponds use the equivalent of 48 horsepower (HP) of aeration be hectare, or 18 HP per pond from six, 1-HP paddlewheels, six 2-HP paddlewheels and air blowers.


The ponds, as normally practiced in Indonesia, have a central discharge system to drain away sludge at least five times a day.  In addition, frequent siphoning is carried out to remove other accumulated matter.


Dissolved oxygen is maintained at above 4.5 parts per million (ppm), pH at 7.6 to 7.9 and alkalinity at 130 ppm.   Probiotics and magnesium sulfate are routinely added to maintain water quality.


For one crop, Bhakty stocked 1,650,000 PLs and at day-57, the feed demand was 525 kg/day.  He used Gold Coin Forte Feeds, with 36% crude protein.  At day-53, shrimp were sampled and averaged 6 grams.  Each pond uses three auto feeders for feeding.  The feed conversion ration was 1.49, harvest size was 18.2 grams and survival was 97%.


Baramuli is also the largest producer of postlarvae in west Sulawesi, currently producing 130 million postlarvae a month.
