Large yellow croaker is China's most important marine aquaculture species, with millions of tonnes produced annually. Rapid expansion of cage farming has raised urgent welfare questions around crowding, disease, and slaughter.
Large yellow croaker welfare is poorly studied relative to salmonids and tilapia. High cage densities create chronic stress, evidenced by fin damage, elevated cortisol, and increased disease susceptibility. The species' sensitivity to acoustic disturbance means boat traffic and net handling cause acute stress responses. Mortality rates during typhoon events — when cages are exposed to extreme wave action — can be catastrophic. Market practices in China often involve live transport and sale, meaning fish experience prolonged confinement during distribution. The lack of welfare-focused regulation in this sector, combined with the enormous scale of production, means that even incremental improvements in stocking density or slaughter practice could benefit millions of animals. International aquaculture welfare standards are beginning to extend attention to Asian species, but large yellow croaker remains a low-priority species for welfare research.
