Global shrimp farming produces over 4 million metric tons annually — with welfare considerations that are only beginning to receive the attention this scale demands.
Farmed shrimp welfare represents one of the largest welfare challenges in aquaculture given the enormous numbers involved and the relatively early stage of welfare science for this taxon. Shrimp are not the simple reflex machines they were once assumed to be — their nociceptive systems and behavioral responses to aversive stimuli suggest capacity for some form of pain experience. The eyestalk ablation practice used to induce spawning in broodstock is particularly concerning — it is painful, permanently disabling, and could be replaced with alternative induction methods that are available but not yet widely adopted. Scaling welfare improvements for shrimp requires sustained research, consumer pressure, and regulatory engagement with an industry accustomed to treating these animals as entirely welfare-irrelevant.
