Groupers are large reef fish that are heavily targeted by commercial and recreational fishing. Their welfare and ecological role in reef systems make their protection a welfare and conservation priority.
Grouper welfare in the live reef fish trade involves significant suffering. Fish caught on long-lines or with cyanide are held in nets or tanks for extended periods before transport in cramped conditions. Cyanide fishing stuns target fish and kills surrounding reef organisms. Long transport reduces fish health and increases mortality. Spawning aggregation fishing concentrates capture effort precisely when groupers are most vulnerable behaviorally, disrupting a fundamental reproductive drive. Both conservation and welfare arguments support strong protection of grouper spawning sites.
