Aquaculture in a changing climate
In the OCCAM project, 22 partners from different parts of Europe will, over four years, investigate how different types of aquaculture can adapt to a changing climate while reducing the carbon footprint of aquaculture.
The OCCAM project (Operationalizing Climate Change Adaptation and Mitigation for Aquaculture) aims to develop and test new solutions to adapt aquaculture to climate change and reduce aquaculture's greenhouse gas emissions. The project will also develop recommendations and practical solutions for different types of aquaculture.
Through experiments, OCCAM will test new technologies in aquaculture across Europe, with species such as carp, trout, salmon, mussels, oysters and seaweed. In addition, the project will develop low-emission nets and cages. The idea is that the solutions developed can also be used by other types of aquaculture with similar challenges.
In addition to the experiments, OCCAM will develop tools for self-assessment of greenhouse gas emissions, a roadmap for meeting sustainability reporting requirements and a policy report for climate-resilient aquaculture.
IVL's main components are field trials with oysters and seaweed, and assessing the environmental impact of the solutions developed around different species, as well as conducting life cycle assessments for a selection of them.
