Production methodFarmed Ponds
Source of fry
A low proportion of fish meal is used for feed ingredients. However, it has a high proportion of imported GM soybean meal and rapeseed meal.
This type of production method results in the discharge of excessive fish feed, faeces and chemicals into surrounding environment, potentially causing negative environmental impact. The escape impact of the fish is moderate to high.
There is no comprehensive environmental impact assessment for this production method. China is focusing on land and water use, habitat protection, and chemical usage. The overall management is partly effective.
