Biosecurity in shrimp farming is a series of activities designed to deter the entry of disease into the farming system and prevent the spread of disease from an infected farm. Failure of the implementation of biosecurity programs are at risk of disease spread within the culture as well as in environmental waters due to crop failure and subsequent decline in production.

Pond Preparation
Each type of farm has different stages with each other. To reduce the risks and constraints to disease at the time of culture period, preparation must be done as carefully as possible.  For ponds with full HDPE, pond preparation includes cleaning the pond bottom and walls of the rest of the dirt (mud, tritip, shellfish and others), cleaning and repair of plastic and Paddle Wheel Aerator (PWA), and sterilization using chlorine at the bottom of the pond and in the pipe.
