Global shrimp farming produces over 5 million tonnes annually under intensive conditions that raise significant welfare concerns, particularly given growing scientific evidence that decapod crustaceans are sentient beings capable of experiencing pain and distress.
The welfare status of farmed shrimp has been largely ignored in food system debates, yet the scale of production — hundreds of billions of individuals annually — makes this one of the most numerically significant animal welfare issues in agriculture. Evidence indicates that shrimp have nociceptors, respond to noxious stimuli, and show learned avoidance behaviour consistent with pain experience. Practices such as eyestalk ablation, which causes prolonged injury to force reproduction, would be prohibited if applied to vertebrates. The sentience evidence and production scale justify urgent attention to shrimp welfare standards.
