Pond preparation and food requirements
1. Carry out thorough pond preparation such as crack drying, liming and tilling once a year.
2. Prepare the ponds grown with lab-lab before fish stocking.
3. Apply organic and inorganic fertilizer to stimulate growth of natural food organisms.
4. Extend pond preparation and food growing in grow-out ponds to 45 days to allow more time for the abundant growth of lab-lab.
