Wild shrimp play important ecological roles in marine food webs, and their welfare in both wild capture and their position as prey species raises questions about invertebrate welfare at ecosystem scale.
Wild shrimp welfare in trawl fisheries raises the precautionary welfare concerns that apply to all potentially sentient invertebrates at massive scale: billions of individual shrimp subjected to the acute stress of trawl capture, compaction in nets over hours, sorting, and either death as target catch or discard death as bycatch. If shrimp have any capacity for negative experience — a question the scientific literature has not resolved — then trawl fisheries create welfare harms of extraordinary magnitude. The ecological destruction of trawling — destroying benthic habitat, generating massive bycatch mortality — compounds the direct shrimp welfare concern with second-order welfare impacts on the entire marine community disrupted by trawl passage.
