01 — Our story
We stayed in the estuaries when the rest of the industry moved offshore.
NaturaFish was founded on the belief that aquaculture should look more like nature and less like industry. While most of the world moved seabass and seabream into high-density offshore cages, we continued perfecting traditional estuary farming, in the same habitat where these species live and thrive.
Today, under the leadership of CEO Miguel Theriaga, we run two farms in the Ria de Alvor and Rio Arade, supplying premium fish to chefs and distributors across three regions.
Extensive aquacultureNaturally sustainableAlgarve, Portugal
Our 40 hectares of ponds sit on two adjacent estuaries in the western Algarve. Both of these protected estuarine ecosystems are known for clean water and rich biodiversity.
02 — What we believe
A fish that lives well tastes better.
Lower densities, natural tidal feeding, and slower growth produce a healthier animal and a finer product. We see our role as stewards of the estuaries we farm in — protecting water quality, biodiversity, and the long-term health of the ecosystem.
01
Natural habitat
Estuaries and inlets are where European seabass and gilthead seabream actually live in the wild.
02
Low density
We give our fish room to swim, socialize, and grow at their own pace.
03
Tidal feeding
Twice-daily tidal exchange brings natural feed into our ponds, supplemented only with cereals and fish oils.
04
Ongoing R&D
We reinvest a substantial portion of our profits in research and development to keep refining extensive aquaculture for the next generation.

05 — Sustainability
Our sustainability commitments.
We're working toward ASC (Aquaculture Stewardship Council) certification by 2027. But more importantly, our farming methods already reflect ASC standards. Sustainability isn't an add-on for us; it's the entire model.
