European perch aquaculture is expanding as a premium freshwater species, with welfare research identifying water quality, density, and slaughter as key improvement areas.
Farmed perch welfare is shaped by their territorial nature, which makes high stocking densities particularly stressful and injury-prone. Water quality management including oxygenation and temperature control is critical for health and welfare. Pre-slaughter stunning using electrical methods provides rapid insensibilization and represents the most achievable near-term welfare improvement for this species. European certification schemes are beginning to incorporate perch-specific welfare standards.
