How emerging technologies are creating new possibilities for monitoring and improving welfare in aquaculture settings for fish and invertebrates.
Aquaculture welfare technology is advancing rapidly, driven by both genuine welfare concern and the commercial reality that stressed, unhealthy fish produce lower-quality products. The scale of aquaculture — billions of individual fish and invertebrates — means that technology offering continuous, non-invasive welfare monitoring could transform the field. Underwater camera systems that detect aberrant swimming, acoustic monitors that identify abnormal school behaviour, and environmental sensors that alert operators to welfare-compromising parameter changes are all moving from research to commercial deployment. These technologies cannot replace genuine commitment to welfare, but they can extend the reach of welfare monitoring far beyond what human observation alone can achieve.
