“Sustainable” is not one data field.
Start by naming what is actually being claimed: farm system, feed, certification, environmental performance, community impact, product origin, or a combination. Each claim needs its own source, scope, and date.
A comparison is only useful when the records use comparable boundaries. An ocean-farm description, a RAS facility description, and a certification claim may all be relevant, but they do not mean the same thing.
- System: ocean, floating, land-based, RAS, hatchery, or processing context.
- Scope: organisation, facility, brand, product line, or specific site.
- Standard: certification name, owner, status, and coverage.
- Freshness: observation date and whether the source is still current.
Follow the evidence, not the slogan.
The catalogue currently links Barramundi Group’s published ocean and land-based RAS farming descriptions to a BAP accreditation record. It also records Australis’s published Fair Trade programme claim. These are useful source leads with different scopes; neither is a universal sustainability score for all barramundi.
Where feed composition, emissions, water use, escapes, biodiversity, or community outcomes are not published in the current record, they remain unknown rather than inferred.
Ask for the boundary before comparing suppliers.
A procurement brief can turn sustainability into checkable questions: which site, which product, which period, which standard, and which document? That produces a more useful conversation than a generic green label.
