Pathogens and Contaminates in Pond Water

Fish farming can be a great way to increase revenue for many farmers, but the water used in aquaculture may become contaminated. Pathogen contaminated fish and aqua plants can pose a serious health risk.

Clonorchiasis (liver fluke) and pistorchiasis are pathogens that are transmitted directly from fish. Other pathogens can contaminate plants that are then used as a food source for other animals that are raised for human consumption.

Another host for pathogens found in aquaculture farms is snails, which pose an occupational hazard for farm workers who often wade into the ponds. If an open wound or a cut in the skin is exposed in an area where infected snails are located, the pathogens may be transferred.

In addition to pathogen contaminates, fish may also carry bacteria and viruses in their scales or gills. The bacteria and viruses are a bigger concern in Asia where the fish is often eaten raw. Pregnant women may also experience additional pregnancy symptoms if the contaminated fish is undercooked.

Reducing pathogens and contaminates in fish ponds is a critical step in running a profitable fish farm.
