"Pond Preparation and Transfer Techniques in Prawn Culture"

The success of prawn farming is determined by how well the pond is prepared and how well the different stages of life (larvae) are transferred to their new environment. The preparation of a pond includes a number of stages including drying, tilling, liming, fertilization and conditioning the water in order to build an environment where prawn can thrive. The processes of pond preparation improve the quality of the soil, help control harmful organisms and enhance the development of natural food sources. A second equally important aspect of pond preparation is the manner in which the prawn post-larvae are transferred to their new environment; acclimatizing the larvae to the water conditions, temperature and salinity of the pond, and the use of careful handling techniques to minimise stress and reduce mortality of the transferred larvae all help to maximise the survivability and growth of the newly transferred post-larvae. Proper timing and biosecurity methods also contribute to improving the survival rate and growth rate of transferred post-larvae. Proper management of pond preparation and transfer techniques enhances production efficiency, improves the health of prawns, and will create an environment where sustainable aquaculture can flourish.
