Shrimp farming produces enormous quantities of the most consumed seafood globally, with significant and tractable welfare improvement opportunities.
Shrimp welfare represents one of the highest-impact opportunities in animal welfare because of the enormous numbers involved and the low cost of improvement. If shrimp can experience something like pain — and the evidence is growing that they can — then the current standard of slow death by ice immersion causes suffering at a scale that dwarfs almost any other food production welfare issue. Electrical stunning at slaughter would cost fractions of a cent per animal and could be implemented industry-wide rapidly with appropriate regulatory or market pressure.
