In 2022, Nueva Pescanova, Spain’s largest fisheries company, announced plans to invest €65 million ($76 million) in what would have been the world’s first industrial-scale octopus farm and processing facility near Las Palmas, a major port on the Canary Islands. The company projected annual production of 3,000 tonnes of octopus by 2025 at the Gran Canaria site, aiming to meet growing market demand for the species.

Octopus farming has long been recognized as a complex challenge due to the biology and behavior of the common octopus (Octopus vulgaris), the species targeted by Nueva Pescanova. Experts note that octopus larvae spend a prolonged period—approximately 20 days—freely drifting in the water column before settling to the seabed, making controlled cultivation difficult. Feeding the animals is another major obstacle, as octopuses are selective eaters and tend to reject monotonous diets. Some specialists argue that the cost of feed could surpass the market value of farmed octopus, undermining economic viability.

Despite the initial enthusiasm, opposition emerged from animal welfare groups, scientists, and segments of the public, highlighting the ethical concerns associated with farming an animal widely regarded for its intelligence and complex behaviors. Researchers and campaigners underscored the octopus’s sophisticated nervous system and problem-solving abilities, which raise moral questions about confining them in artificial environments. The debate was further intensified in popular culture by Craig Foster’s documentary "My Octopus Teacher," which portrayed the octopus as a sentient being capable of reciprocal interaction with humans.

In late July 2026, Nueva Pescanova informed the Canary Islands port authority that it was abandoning the octopus farm project, attributing the decision to “business and regulatory” challenges. Following the announcement, Spain’s animal rights party, Pacma, framed the outcome as a success borne of “social, scientific and political pressure” opposing what it called an “ethical and environmental atrocity.” However, local journalists noted that public protests had been relatively small, suggesting that questions of commercial feasibility may have been more decisive.

While Nueva Pescanova’s plan to farm common octopus remains unrealized, a smaller-scale operation in Mexico has succeeded in cultivating a different octopus species. The global pursuit of octopus aquaculture continues, driven by the species’ rapid growth, short life cycle, nutritional benefits, and market demand. Some proponents argue that octopus farming—if managed sustainably—could offer an environmentally preferable alternative to traditional livestock.

Nonetheless, critics caution that the ethical dilemmas surrounding the intelligence and solitary nature of octopuses will persist as significant barriers. Charlotte Reid, a campaigner at Compassion in World Farming, asserted that octopuses are wild animals that belong in their natural habitats, not confined settings described as “underwater prisons.” As the industry grapples with these scientific, technical, and moral considerations, the future of octopus aquaculture remains uncertain.
