Harvesting Prawns

Prawn harvesting times are largely determined by the Prawn’s condition, market demand and the price. Cast nets are used to collect them from different areas of the growing pond based on their average weight, shape, and size. The soft shell should not exceed 5 percent in the pond at harvesting. You can achieve this by scheduling harvesting the Prawns in between two moultings. Exuviae found in the growing pond can indicate that there is molting.

Harvesting should take place after one week if your Prawns are weighing in at 30 gm. You can observe the next molting in two weeks.
