Tilapia is one of the most farmed fish globally, yet welfare standards for its production are largely absent. Understanding tilapia welfare helps consumers make more informed choices.
Tilapia's hardiness has made it a staple of global aquaculture, but this same resilience has been used to justify conditions that would be welfare failures by any reasonable standard. The ability to survive in poor water does not mean that a tilapia is not suffering in those conditions - stress responses, suppressed immune function, and behavioral changes indicate significant welfare compromise even in 'tolerant' species. The use of methyltestosterone to create monosex male populations raises additional concerns about medicating millions of fish at the larval stage with little welfare scrutiny. As tilapia production continues to grow, establishing minimum welfare standards for one of the world's most consumed fish represents a significant opportunity for impact.
