Sensor technology, computer vision, and artificial intelligence are beginning to enable continuous welfare monitoring in aquaculture - potentially transforming the ability to detect and respond to fish welfare problems.
Welfare monitoring technology represents a genuine opportunity to improve fish welfare in aquaculture at scale, but its potential depends on how it is deployed. Technology that generates welfare data without clear linkage to management decisions - because protocols for responding to welfare alerts do not exist or are not followed - provides little welfare benefit. The most promising welfare technology integrations are those that establish welfare thresholds, trigger automatic or rapid human responses when thresholds are breached, and allow welfare performance to be tracked and improved over time. The welfare benefit of early detection of disease outbreaks, crowding stress, or oxygen depletion events could be substantial - preventing mass welfare deterioration rather than responding to it after damage is done. The technology is advancing faster than welfare standards development.
