HIGH DENSITY JUVENILE SHRIMP (Penaeus monodon) PRODUCTION WITH DIFFERENT DURATIONS OF REARING IN ACID SULFATE SOIL-AFFECTED POND
Abstract: An experiment was
conducted to evaluate the effectiveness of producing juvenile shrimp in a
reservoir pond constructed in acid sulphate soils (ASS). Many ponds constructed
in ASS pose a significant economic risk due to high mortality and poor growth.
In Indonesia, abandonment of ponds in ASS is widespread and alternative farming
practices, such as production of juvenile shrimp, offer farms opportunities to
lower their production risks. The experiment involved rearing juvenile shrimp
at a high stocking density (3,000 individuals/m2) using hapas in a formerly
unproductive pond located in Luwu Regency, South Sulawesi, Indonesia. The
treatments tested included rearing periods of three and six weeks with four
replications. A survival of 83.62% was achieved after rearing for three weeks
compared to 45.44% after six weeks. Although there was a sixfold increase in
the mean weight of shrimp from three to six weeks of culture, size variation
after six weeks was large due to the high density of shrimp. The experiment
showed that old acid sulphate soil-affected ponds, in which the bottom soil has
not been excavated any further, can be used for production of juvenile shrimp
in hapas. Rearing over three weeks is recommended to obtain high survival and
reduce size variation.
