Feed
No feed is used with this production method. There is no fishing pressure on wild stocks.
Ecological effects
Due to intensive farming, the cage units themselves and net biofouling will cause a slowdown in water flow, which increases water pollution. The risk of farmed abalone escaping to the wild is low to moderate. Major regional disease outbreaks are a significant problem that may lead to potential environmental impacts. Habitat alterations under this production method are low to moderate.
Management
China focuses on land and water use, habitat protection and chemical use. There is a lack of comprehensive environmental impact assessment. Overall management is partly effective.
