Summary:Cage Aquacultures Environmental Effects

Cage farming in the sea will introduce a large amount of waste into the surrounding environment. Sewage from the cage contains by-products such as high-level nutrients, waste feed, fertilizer and seafood. Sewer will adversely affect the local environment. The degree of influence will depend on the movement of water around the cage, the ability of the environment around the cage to assimilate, and the rate at which sewage is generated. However, the environmental impact of sewage is thought to be irrelevant to industrial and agricultural inputs.

NOAA is committed to supporting economic, environmental and socially sustainable fish farming. NOAA experts and partners promise to understand the environmental impact of aquaculture in various environments and to provide the best management method to reduce the risk of adverse effects. Aquaculture is the breeding, breeding and harvesting of fish, shellfish and aquatic plants. Basically it is cultivated in water. Aquaculture in the United States is a source of environmentally conscious food and goods that helps to create healthy habitats and rebuild populations of threatened species.

Sustainable aquaculture means producing long-term fish and other aquatic life without causing environmental risks or damage. Aquaculture includes freshwater, brackish water and marine aquaculture under controlled climatic conditions. However, aquaculture does not mean sustainability. In Vietnam, more than half of the country's mangroves were destroyed and access to the fish pond was allowed. Mangroves play an important role in ecosystems to provide food, shelters and wild materials for other aquatic animals and living things. In addition, shrimp has been suffering from various diseases for the past 15 years and is effectively consuming inventory.

Transferring aquaculture to the onshore recycling system is one of the best ways to mitigate or eliminate the environmental impact of cultured fish. Recirculation aquaculture system (RAS) is a technology to create conditions suitable for aquaculture using indoor tanks, pumps, aerators and filters, achieving a maximum of 100% water recovery in the system through new development You can design to do. The possibility of land RAS is infinite. They can be used not only as a strategy to mitigate the impact on traditional aquaculture environments but also for aquaculture in urban areas and deserts. In fact, desert aquaculture provides exciting opportunities for areas such as the Middle East and North Africa.
