How to Apply Fermented Rice Bran in Shrimp Farms
Fermented rice bran has a distinct aroma which is similar to fermented cassava. If you detect a foul smell, discard the fermented rice bran as it may have been contaminated by harmful microbes that can poison the shrimp. Repeat the fermentation process and ensure the container is completely sealed to prevent contamination.
Apply the fermented rice bran in the pond three times a week in the afternoon or evening. Wait 5-7 days to observe changes in pond water color due to plankton growth. Stop applying rice bran once the water has reached a brownish green color.
Conclusion
Fermented rice bran is one type of treatment in the farm for farmers who want to improve water quality by promoting plankton growth. Rice bran can be fermented with the Lactobacillus bacteria and yeast in a sealed container for 24 hours and applied to ponds thrice a week until the pond water turns brownish green.
