Aquaculture means farming of fish which many organism are live inside the water. It also depending the system design either indoor or outdoor ponds or tanks system.
Usually feeding excessively to accelerate production ends up creating too much waste which turns into sludge and decreases the quality of water. To prevent the fish from getting sick from the polluted water, antibiotics and other medicinal products are often put in the water. This affects the surrounding environment, endangers fish communities and habitat, and puts food safety at risk. Then, the concentration of wastes increases (BOD) microbial activity and drops dissolved oxygen (DO) in the ponds or tanks, starving the fish from oxygen. This stresses the animals and can kill them. EM is effective at controlling these issues.
Benefits of using EM products in aquaculture:
Improvement of Water Quality
Solution For Sewage
Improvement of Water Quality in Farm Ponds and Prevention of Accumulation of Sludge.
The use of EM products can accelerate fermentation of fodder wastes, thereby preventing accumulation of sludge. Also, EM and the metabolites produced by EM can activate microorganisms in water, reviving aquatic ecosystems and enhancing their self-cleansing ability. As a result, water quality in farm ponds improves and sludge does not build up in the environment.
Sickness Prevention (EMS, White Spot Syndrome Virus), Reducing Reliance on Medicine such as Antibiotics and Anti-bacterial Agent.
When an ecosystem diversifies and enhances its self-cleansing ability because of EM products, the reproduction of certain viruses can be prevented and thus the dosage of antibiotics and antibacterials can be reduced. There are successful cases in which EMS and White spot diseases have been eliminated by the use of EM in shrimp farming.
Concurrent use of EM products and added organic matter speeds up decomposition. It improves both the physical and chemical properties of soil, while sharpening its buffering capacity. These measures guard against salt damage in maritime environments.
Reducing Stress in Fish and Shellfish.
Stress levels in fish and shellfish depend significantly on water quality. EM products helps to maintain water quality and, therefore, stress levels can be reduced. As a result, fish can be kept healthy and free from sickness.
In farming operations in which water quality has been improved by EM, product quality also improves. For example, odors given off are lessened and the taste becomes milder. It is also possible to reduce the amount of residual antibiotics and bacteria in the end product. This enhances food safety, benefitting manufacturers and consumers alike.
Solutions for Sewage: Waste Water from Farm Ponds Won’t Damage the Environment.
When using EM products, waste water quality can be improved so discharge won’t negatively affect the surrounding environment. Also, it is possible to minimize the use of antibiotics and anti-bacterial agents, thereby helping to reduce the environmental burden. (In the case of Chinese Shanghai Crab Farming, water quality at deeper depths can be stabilized.)
In conclusion, EM is compatible with various methods of farming, regardless their scale. It is effective because it diversifies the population of beneficial microorganisms in water.
