Loch Duart

A genuine, differentiated Scottish salmon farmer with practices materially better than industry norm: ~1.5% fish to 98.5% water stocking density, rotational fallowing (one site in three fallow for a full year, plus 5-12 month sea-site fallowing), swim-through pens in strong natural currents, slow growth, no antibiotics or hormones, wrasse used as biological sea-lice control, MSC-certified feed inputs and a published ~0.8kg wild fish per 1kg of salmon ratio. Held back from exemplary by the certification gap below — the practices are real but currently self-attested rather than third-party audited.

Scale

Mid-size independent Scottish farmer; expanding (Skye expansion reported to roughly double production).

Feed & inputs

High marine-content feed with MSC-certified ingredients; ~0.8 kg wild fish per 1 kg salmon produced (better than 1:1).

Animal welfare

Low stocking density (1.5%), swim-throughs, minimal handling, wrasse for lice control, no antibiotics. Currently NO third-party welfare certification — developing its own in-house welfare standard.

Environmental

Rotational fallowing is the strongest environmental practice in the file; biological (not chemical) lice control.

Transparency

Medium. Method is published in detail, but the company left independent certification and its replacement standard is its own — self-certification is weaker evidence.
