WP2

Validation of welfare indicators

Behavioral welfare indicators at the individual level and at group level will be validated in rainbow trout, sea bream and sea bass. The behavioral response to different aquaculture stressors (different levels of dissolved O2, CO2, ammonia) will be monitored by video recording (group spatial distribution) or by using tail beat sensors (individual activity) in fish of different SCS (proactive vs reactive). The use of feeding behavior with on-demand feeders will be also validated in sea bream. To validate the behavioral changes as welfare indicators, brains and blood will be sampled to analyze plasma and brain stress markers, along with the brain expression of stress-related genes.
