Pure risks are those that arise due to unexpected circumstances such as theft, outbreak of diseases, unexpected extreme climatic factors, malicious damage, legal actions against the farm etc. Examples of extreme climatic risks are flooding, drought and deposition of silt. Flooding, for instance, can result in physical destruction of ponds, loss of fish, and the introduction of pathogens or predators through floodwater. Deposit of silt causes turbidity, which harms aquatic life by degrading spawning beds and affecting gill function, as well as reducing light penetration and level of photosynthesis.

Business risks are those directly affecting the fish production process, and the commercial business of fish farming. They include production risks such as faulty equipment, late delivery of feed, lack of technical information and expertise, unfavourable government policies, changes in operational costs, in addition to market related risks such as poor quality of fish, and consumer-related risks like change in the taste of consumers, competition from alternative commodities, and health factors.

The pond site should be located in a flat, well-vegetated drainage basin land, ideally above the flood plain to prevent flooding and washing away of the farm during heavy rains.

6. Careful monitoring and observation of fish behaviour for any irregularity (e.g. fish off feed, erratic swimming) will provide sufficient warning that a problem is looming.
