IUCN status
Not evaluated
Source of fry
Hatchery based woith juveniles production using wild-caught broodstock.
Feed
Feed comes from a vast array of sources and is largely pellet feed. The feed formula mainly consists of soybean meal, and most of them being genetically modified.
Ecological effects
Chemicals are used to prevent diseases with this production method, which affects pond water quality. Meanwhile, water discharges increase eutrophication in the surrounding area. Since farmed grass carp are hatchery based, escaped fish may create moderate to high impacts on the wild populations.
Management
There is a lack of comprehensive environmental impact assessments. Mainland Chinese regulations focus on land and water use, habitat protection and chemical usage. The overall management is partly effective.
