Tilapia is one of the world's most farmed fish species, yet welfare conditions in intensive systems vary enormously. Understanding tilapia's stress responses and needs is essential for humane production.
Tilapia are hardy fish but hardiness does not mean insensitivity. Intensive farms frequently operate at stocking densities far above welfare thresholds, leading to chronic stress, compromised immunity and increased disease rates. Water quality failures - low dissolved oxygen, ammonia spikes - cause acute suffering. Male-only monoculture systems, produced through hormonal sex reversal, raise additional ethical questions. Welfare certification schemes for tilapia remain underdeveloped compared to salmon, leaving billions of fish outside meaningful protection.
