Farmed shrimp is one of the most traded seafood commodities globally. Growing scientific understanding of crustacean sentience raises important welfare questions about this massive industry.
Farmed shrimp welfare sits at the scientific frontier of crustacean sentience research. Evidence from behavioral studies and neuroscience increasingly supports that shrimp have nociceptive systems capable of generating pain-like experiences. If this is confirmed, the welfare implications of farming billions of shrimp in high-density systems with often poor water quality and stressful harvest conditions are profound. Precautionary welfare approaches suggest minimizing practices likely to cause suffering, including improving water quality, reducing density, and developing humane harvest and slaughter methods. Consumer awareness of this emerging issue can drive both research investment and industry attention.
