The difficulty of corrupting information in the block chain strengthens the traceability of fish products along the value chain, which will enable more fisheries, aquaculture farms and fish processing facilities to meet import requirements such as the country of origin and phytosanitary standards of many countries. Improved traceability will also make it possible to fulfil growing buyer demand for legally and responsibly sourced fish. In some fisheries and aquaculture farms, it will assist in meeting certification requirements.
