Sustainability overview

Seabass in France can be farmed in land based tanks known as recirculating aquaculture systems (RAS). These enclosed systems have the advantage of not having any interaction with the surrounding environment and prevent escapes, pollution and disease transfer. Fish farmed in this way are a good environmental choice.

Feed Resources

Criterion Score: 0

Sea Bass are a fed species, requiring a commercial diet containing fish and vegetable proteins and oils. Sea bass produced in France use traceable, responsible feed. Seabass require fishmeal and fish oil in their diet making them a net consumer of fish protein rather than producers.


Environmental Impacts

Criterion Score: 7

Sea bass produced in a fully enclosed recirculating system address all of the issues of environmental concern such as escapes, discharges, habitat impacts and disease transfer.


Fish Health and Welfare

Criterion Score: 0

It is unknown if any fish welfare and humane slaughter standards are in place for this production method, however the fully enclosed system does prevent widespread transfer of disease outside of the production system



Criterion Score: 3

Overall the management is effective as the land based fully enclosed nature of the production system does not require the same regulation or planning requirements as an open system. This system is not certified to any independent production standards.

Bass or seabass belongs to a family of spiny-finned fish called Moronidae, which are closely related to groupers. Bass breed from March to mid-June, mostly in April, in British coastal and offshore waters. From January to March in the Bay of Biscay and from February to May in the English Channel and eastern Celtic Sea. It is a long-lived and slow growing species - up to 30 years of age, and can achieve a length of up to 1m with a weight of 12kg. Male bass mature at 31-35cm (aged 3-6 years) and females mature at 40-45cm (aged 5-8 years). Once mature, bass may migrate within UK coastal waters and occasionally further offshore. Increases in sea water temperature in recent decades has likely led to a more northerly distribution of seabass as it is now found further north into the North Sea. Climate warming may also have lengthened the time adult seabass spend in the summer feeding areas. After spawning, seabass tend to return to the same coastal sites each year.
