Aquaculture refers to farming specific kinds of fish in contained areas. As a result of the high level of concentration, stringent ecological management is required. Feeding excessively to speed up production usually ends up creating too much waste, which turns into sludge and diminishes water quality. In order to prevent the fish from becoming sick from the polluted water, antibiotics and other medicines are often put into the water. This affects the surrounding environment, compromises fish communities and habitat, and endangers food safety.
Merits of using EM products in aquaculture
EM has been used to break the vicious cycle created by current fish farming practices. The technology has proven effective in crab farming operations in China, as well as shrimp cultivation in Thailand, Vietnam and Ecuador. Use of EM can help activate beneficial microorganisms in water, thereby diversifying the ecosystem and enhancing its self-cleansing ability. Thus, it prevents biofouling. As the water quality improves, farm ponds can support more kinds of plankton (improving biodiversity), which can keep the environment healthier for fish.
