Aquaculture Welfare

Farmed Trout Disease Management

Farmed rainbow trout face significant disease challenges including whirling disease, bacterial kidney disease, and viral haemorrhagic septicaemia, with prevention prioritised over treatment for welfare.

Key Facts

Rainbow trout are the most widely farmed freshwater fish species globally
Furunculosis caused by Aeromonas salmonicida causes systemic disease and significant mortality
Vaccination programs prevent bacterial infections with fewer welfare costs than treatment
Water temperature management affects disease susceptibility in trout farms
Biosecurity preventing wild fish contact with farmed populations reduces disease risk

Welfare Considerations

Trout disease management follows the same principle as other aquaculture species - prevention through vaccination and biosecurity causes less welfare harm than treating established disease. Investment in farm biosecurity, vaccination, and water quality management represents welfare-positive disease control.
