Sign the global pledge: Keep Them Wild

There are plans to launch the world’s first commercial octopus farm in Spain. This has raised global concern. Farming octopuses would cause immense cruelty to these intelligent wild animals and harm marine life. It also reflects the wider problems of carnivorous aquaculture, an unsustainable industry.

By pledging to Keep Them Wild, policymakers can protect animals, safeguard ecosystems, and lead the way to a sustainable, future-fit food system.

I pledge to support:

  1. Legislation to ban octopus farming and the sale of products from octopus farms

  2. Octopus farming would result in serious animal suffering and significant environmental harm. No humane slaughter methods exist for octopuses, and the solitary, intelligent nature of these wild animals makes confinement in tanks both cruel and unworkable. Beyond these serious welfare concerns, the environmental consequences are equally severe. Farming octopuses would rely on fishmeal and fish oil made from wild-caught fish, as well as a large amount of live or frozen natural food such as crustaceans and fish, stripping the oceans of vital forage species that underpin marine food systems, and provide food security for millions of people. Therefore, legislation is needed to prevent the emergence of commercial octopus farming.

  3. No expansion of farming to new carnivorous species

  4. The expansion of aquaculture into new carnivorous species, such as tuna, cod, and octopus, risks repeating and amplifying the mistakes of factory farming on land. These animals are sentient and, in many cases, highly intelligent, with complex behavioural and physiological needs that cannot be met in captivity. At the same time, farming them would increase demand for fishmeal and fish oil, putting additional pressure on already overexploited wild fish populations and undermining marine biodiversity.

  5. A gradual phase-out of the use of wild-caught fish for aquafeeds

  6. The use of purpose-caught wild fish in aquafeeds represents both an animal welfare and environmental crisis. Billions of sentient animals are removed from the oceans each year to be reduced into fishmeal and fish oil, depriving marine ecosystems of essential species and reducing food security for coastal communities who depend on these fish directly for food. Phasing out the use of wild-caught fish in aquafeeds, and replacing them with sustainable alternatives such as by-products, algae, or plant-based proteins not suitable for human consumption, is essential to reduce suffering, protect biodiversity, and build a more just and sustainable aquaculture sector.

Sign the pledge today to keep marine life wild, free, and thriving, and to demand an end to the expansion of unsustainable carnivorous aquaculture.

Sign as a policymaker

Octopus farming is a threat to animals, food security, and marine life. It has also become a powerful symbol of a wider danger: the unsustainable expansion of carnivorous aquaculture.

Expansion into new carnivorous species can heighten the risk of local water pollution and disease outbreaks. Reliance on fishmeal and fish oil made from wild-caught fish could further undermine food security, place additional pressure on marine ecosystems, and accelerate the depletion of our oceans. For the octopus, a highly intelligent and sentient being, there is still no legislation in place to safeguard their welfare.

The Keep Them Wild campaign is a response, which started in the Canary Islands, Spain. Here, plans for the world’s first commercial octopus farm exposed the dangers of industrialising these intelligent, sentient animals. Wild means alive, free, and thriving in their natural ecosystems; not confined in tanks and exploited for profit.

By pledging to Keep Them Wild, policymakers have the opportunity to protect animal welfare, safeguard fragile marine ecosystems, decrease unsustainable fishmeal and fish oil sourcing practices, and strengthen global food security by ensuring small fish feed people rather than factory farms. Signing this pledge is also a chance to demonstrate political leadership in shaping a food system that safeguards natural resources, strengthens resilience, upholds ethical standards, and anticipates future needs.

New report: A Growing Threat - The Dangers of Carnivorous Aquaculture

Key highlights:

  1. By 2040, octopus farming in Spain could more than triple, consuming 17,000–90,700 tonnes of wild forage fish each year, undermining ecosystems, food security, and animal welfare.
  2. Farming of carnivorous species such as salmon, trout, seabass, seabream and octopus is driving reliance on fishmeal and fish oil (FMFO) from wild forage fisheries.
  3. In 2022 farmed aquatic animals reached 94 million tonnes, overtaking wild capture at 91 million tonnes for the first time.
  4. Across Europe, production of carnivorous and omnivorous species could rise by nearly one third by 2040, with FMFO demand climbing by up to 70%. Much of this demand will come from Malta and Spain, driven largely by feed-intensive farming of Atlantic bluefin tuna (Thunnus thynnus).
  5. The UK, Greece, and Spain are expected to produce the highest levels of European carnivorous aquaculture production by 2040, after Norway.
  6. Since 1985, 78 new species have been introduced into European aquaculture, 70% of which require animal protein in feed.
  7. Spain is leading expansion: in 2020 it sourced FMFO from 26 countries, the widest network in the region, many linked to IUU (Illegal, Unreported and Unregulated) fishing, where oversight is weak and sustainability standards are low.
  8. Sustainable alternatives exist: farming low-trophic species (mussels, oysters, carp, seaweed) and advancing innovative feeds (by-products, algae, single-cell proteins) can reduce dependence on wild fisheries.
