Between 2010 and 2019, the value of the global octopus trade ballooned to $2.72bn (some £2bn) from $1.30bn (around £1bn), according to data from the UN Food and Agriculture Organisation, while landings only rose around 9 per cent to 380,000 tonnes. However, previous efforts to farm octopuses have struggled with high mortality, while attempts to breed wild-caught octopuses ran into problems with aggression, cannibalism and self-mutilation.
