Methods used on the Spanish farm would be 'cruel' to such intelligent animals say experts, as details emerge.
2022. Prof Birch and his co-authors believe that high-welfare octopus farming is "impossible" and that killing in ice slurry "would not be an acceptable method of killing in a lab".
In a statement to the BBC, Nueva Pescanova said: "The levels of welfare requirements for the production of octopus or any other animal in our farming farms guarantee the correct handling of the animals. The slaughter, likewise, involves proper handling that avoids any pain or suffering to the animal ..."
The tanks would be filled with seawater piped in from an adjacent bay. The tanks would be different sizes for the different phases of the octopuses' life, with the salinity and temperature closely controlled. The plans state that the company has achieved a level of "domestication" in the species and that they do not "show important signs of cannibalism or competition for food".

Leveraging explainable AI for gut microbiome-based colorectal cancer classification - Genome BiologyStudies have shown a link between colorectal cancer (CRC) and gut microbiome compositions. In these studies, machine learning is used to infer CRC biomarkers using global explanation methods. While these methods allow the identification of bacteria generally correlated with CRC, they fail to recognize species that are only influential for some individuals. In this study, we investigate the potential of Shapley Additive Explanations (SHAP) for a more personalized CRC biomarker identification. Analyses of five independent datasets show that this method can even separate CRC subjects into subgroups with distinct CRC probabilities and bacterial biomarkers.
