“[…] If the fish was produced on a farm, the owner could upload information about the farm itself, e.g. a code of conduct, or information about people and fish welfare. The blockchain could also be used to record the composition of the feed and water conditions. Fish caught at sea could be tagged with the location of the trawler and the fishing method, storage conditions (temperate, humidity) could also be logged.
Similar information could then be collated in the processing plant and transportation to the supermarket shelf. At the point of purchase, the consumer would be able to scan a smart label and get instant access to this information.”
