Shrimp aquaculture produces hundreds of billions of animals annually under conditions raising serious welfare concerns. The scale of potential suffering and the lack of welfare standards make this one of the most critical issues in animal agriculture.
The scale of farmed shrimp production means that even modest welfare improvements could reduce suffering across hundreds of billions of animals. Eyestalk ablation is a painful mutilation performed without analgesia as a standard industry practice. High-density farming, disease management through pond treatments, and harvest methods all raise welfare concerns that have received far less scientific attention than equivalent practices for larger animals. The precautionary principle suggests that given evidence of shrimp sentience, better practices should be adopted now rather than waiting for certainty that will be difficult to achieve for animals so different from ourselves.
