Pre-stocking Management The ponds need to be prepared such that the pond environment provides optimum condition for growth of the fish. The pond environment should be free from predators, aquatic weeds, weed fish; it should have optimum water quality parameters and sufficient natural food should be available in semi- intensive culture systems. Pre-stocking part of the management involves the following sequential measures. Eradication and control of aquatic weeds and algae Floating weeds such as water hyacinth, Pistia , etc., very often cover the entire water surface cutting off light drastically, thus resulting in critical reduction in primary productivity of the pond.
