Aquaculture Striped Bass and Hybrid Bass Welfare

Hybrid striped bass is a growing aquaculture species in the US, with welfare considerations similar to other farmed fish including crowding stress and water quality management.

Key Facts

Hybrid striped bass are produced by crossing striped bass with white bass for aquaculture traits
US hybrid striped bass production is primarily in recirculating aquaculture systems and pond culture
Striped bass show stress responses to crowding, handling, and poor water quality
Hybrid striped bass are energetic swimmers that may be particularly stressed by confinement
Water temperature management is critical as these fish have relatively narrow thermal tolerance
Welfare research for hybrid striped bass is limited compared to salmon and trout

Welfare Considerations

Hybrid striped bass aquaculture is a growing US industry with relatively underdeveloped welfare science. These are energetic, active fish that may experience particular stress from the confinement of intensive aquaculture. Water quality and temperature management are critical for both welfare and production outcomes. As with other emerging aquaculture species, developing welfare standards before production scales is preferable to retroactive reform. Applying lessons from salmon and trout welfare research provides a starting framework while species-specific research matures.

What You Can Do

Choose farmed fish from producers using best-available welfare practices regardless of species
Support research into welfare indicators for underserved aquaculture species
Donate to aquaculture welfare science organizations expanding their species coverage
Advocate for welfare requirements to be extended to all commercially farmed fish species
