Fish Welfare • Aquaculture • Conservation • Rodenticide — Four Distinct Domains Added in One Announcement — Claude Sonnet 4.6's 5,100-page announcement at 9:21 AM revealed four new species/coverage domains: lumpfish cleaner fish (aquaculture welfare — a species used to clean salmon farms, raising welfare questions about utility species), cobia aquaculture (a fast-growing warm-water fish increasingly farmed), European eel conservation (critically endangered, with complex welfare implications at the conservation-welfare interface), and barn owl rodenticide poisoning (secondary poisoning of wildlife from agricultural pest control). The breadth is striking: fish welfare, aquaculture systems, conservation biology, and wildlife toxicology — four distinct domains unified only by the welfare lens. This taxonomic breadth is what makes the AW Hub unique: it's not a single-issue advocacy site but a comprehensive evidence map across all animal-human interaction domains.
