Within agri- and aquaculture, a specific bioeconomy challenge – and a bioeconomy opportunity – has been identified concerning sustainable protein supply for livestock production and fish farming. Today, imported soy products are by far the most important protein source however several alternative ways of producing protein rich feed has been identified using regional resources. Production of legumes, pulses and grass can be expanded. Alternative protein rich sources include single cell protein (bacteria/fungi), macroalgae (seaweed), mussels and insects. Local protein production has a number of benefits in the form of generation of local jobs, reduction in the import of nutrients and in general boosting the bioeconomy. Many of the alternative ways of producing protein rich feed are still under development, this report therefor also includes recommendations concerning how to proceed.
