Life cycle assessment of mussels and oysters
Aquaculture New Zealand and the Ministry for Primary Industries engaged thinkstep-anz to carry out a life cycle assessment (LCA) of farmed New Zealand Greenshell mussels and farmed Pacific oysters. The report was published in October 2021.
outlines the potential for open ocean aquaculture (OOA) to help grow New Zealand's aquaculture sector, and
provides information to support informed investment decisions.
The business case's findings show that growing finfish in OOA systems would be profitable. Many of the assumptions in the business case are highly conservative. Different investment approaches could improve the proposition.
The OOA industry is emerging very quickly. This means the cost of technology will reduce over time. This will make aquaculture possible in more exposed parts of the ocean. Fisheries New Zealand is working on future law changes and investment settings to enable sustainable OOA growth.
Since 2022, environmental DNA (eDNA) monitoring has been incorporated into benthic monitoring in Marlborough Sounds salmon farms and the following documents relate to the development and validation of this tool.
