Worldwide institutions gathered on World Octopus Day, October 8, to urge the European Union to halt the planned octopus farming industry within the bloc. Critics argue that large-scale macro farms, like the one reported in Spain, would bring about environmental harm and animal welfare concerns that could clash with the EU’s sustainable food production goals.
Organizations led by the Ocean Born Foundation, along with 37 other NGOs, have warned the European Commission that octopuses are highly unsuitable for farming. They point to serious welfare and sustainability issues that arise when intelligent, sensitive creatures are raised in industrial settings. The signatories contend that allowing octopus farming would undermine Europe’s own commitments to sustainable agriculture and argue for banning the import of farmed octopus products.
This mobilization follows Nueva Pescanova’s announcement about opening what would be the world’s first commercial octopus farm in Las Palmas de Gran Canaria. The plan has drawn criticism from multiple quarters, including scientists who question the feasibility and ethics of such an operation.
A Compassion in World Farming report highlights octopuses as untamed, highly intelligent, and emotionally complex animals that can suffer in artificial environments such as industrial farms. The study emphasizes the emotional and physical pain these animals may experience when confined in farming systems, prompting calls for greater scrutiny and ethical considerations in any commercial octopus production.

The photograph, credited to matte porteous, serves as a reminder of the species in its authentic environment, free from the constraints of production facilities.
Octopuses are solitary by nature, often living and hunting alone. Experts note that confinement in underwater tanks elevates stress levels among individuals, which can trigger aggression and even cannibalism. Such responses raise concerns about animal welfare in controlled farming settings and challenge the practical viability of octopus aquaculture as a humane practice.
Elena Lara, director of Mercy World Agriculture Research and author of the corresponding report, commented on World Octopus Day that people should celebrate these remarkable wild animals instead of confining them to underwater factory farms. Her stance is clear: the time has come to end factory farming and to resist expanding it. Octopuses are highly intelligent creatures capable of feeling pain and distress, a perspective echoed by the signatories who emphasize the broader environmental implications of such farming methods.
According to the coalition of critics, the environmental footprint of octopus farming could exacerbate existing pressures on wild fish stocks. The production model reportedly requires substantial feed, with estimates suggesting that three kilograms of feed are needed to produce one kilogram of octopus meat. Critics point out that much of this feed is intended for other carnivorous species that are themselves not ideal from a sustainability standpoint, as much of the input comprises fish and other marine resources not easily recovered. Proponents of farming counter that a well-regulated system could minimize waste and improve efficiency, but the prevailing sentiment among many conservation groups is cautious, calling for independent verification and robust welfare standards before any large-scale adoption.
In response to these debates, Nueva Pescanova has stated that its planned farm would adhere to strict animal welfare principles and sustainable practices within a circular economy framework. Company representatives argue that European law and the Pescanova policy set the baseline for responsible operation, asserting that genuine scientific evidence will guide the development of their activities. Roberto Moreno, the Fisheries Manager for the company, conveyed to media outlets that evidence of octopus intelligence remains limited, a claim often cited in discussions about the ethics and practicality of farming these creatures. The company also emphasizes that the project intends to begin with farming operations and scale to a capacity of thousands of tons within a few years, highlighting a long-term commitment to comprehensive research and compliance with evolving regulatory standards.
The overall conversation touches on whether science can fully validate the humane and ecological viability of octopus aquaculture. Critics argue that current scientific understanding is insufficient to justify large-scale farming, while supporters maintain that ongoing research could reveal methods to manage welfare concerns responsibly. The dialogue continues as policymakers, scientists, industry players, and conservation groups weigh the potential benefits against the risks to ecosystems and animal welfare.
Environmental stakeholders stress the broader implications, including the potential strain on marine ecosystems if farming expands without stringent controls. They advocate for precautionary measures and insist that any progress in octopus aquaculture be matched by transparent reporting, independent audits, and clear welfare benchmarks. This careful approach aims to ensure that innovations in seafood production do not come at the expense of animal welfare or ecological integrity.
In summary, the World Octopus Day discourse centers on balancing appetite for new protein sources with ethical considerations and environmental stewardship. While some players in the industry point to opportunities for controlled farming and scientific validation, the consensus among many advocacy groups remains cautious. The call to action stresses the importance of maintaining high welfare standards, protecting wild fish stocks, and avoiding the normalization of factory-like practices for intelligent marine creatures.
Endnote: The ongoing debate reflects a broader global conversation about sustainable aquaculture, animal welfare, and responsible seafood consumption. As science progresses and regulatory frameworks evolve, stakeholders will continue to monitor developments in octopus farming and its potential role in future food systems. Documentation and independent assessments will be critical in shaping whether octopus farming becomes a regulated, welfare-conscious component of the industry or is halted in its tracks to protect marine life and ecosystems.
