New Zealand mussels depend on the collection of wild seed using non-destructive fishing methods
This species mainly filters phytoplankton from the water, so no feed is required in this production method. There will be no fishing pressure to wild stock.
Since this species is a filter feeder, there is no waste discharge. This type of production method can contribute to both negative and positive ecological effects on the surrounding environment and habitats. The escape risk is high, but green mussels are native to New Zealand, so the escape impact is low. The New Zealand mussel can be affected any time by diseases both bacterial and viral, however, no chemical is used.
New Zealand’s aquaculture regulations are broad enough to address the majority of issues related to this activity including mussel farming. The regulatory framework is largely effective.
