Farming Sentient Invertebrates

The octopus is a large-brained mollusc (a relative of snails and slugs) with impressive abilities to perform learned responses. Many scientists are now convinced that these animals are sentient (capable of self-awareness). In the UK, some octopus species now receive animal welfare protections, along with all vertebrate animals. There is, however, concern that a Spanish company Nueva Pescanova is pumping 65 million euros into 'industrial scale' breeding of octopuses for human consumption (https://www.reuters.com/business/environment/worlds-first-octopus-farm-stirs-ethical-debate-2022-02-23/). Some experts are predicting that Neuva Pescanova's planned octopus 'farms' will be an 'ethical and environmental disaster'. They point out that captive octopus have a high mortality. Octopus have also been recorded to show 'aggression' towards conspecifics (members of the same species), cannibalism and self-mutilation. Perhaps self-aware octopus don't like the idea of being served up on a dinner plate or appearing in paella?
