RESPONSIBLE SOURCING is not only about fish, it’s about sustaining ecosystems and livelihoods as well. Through close working partnerships with our suppliers, we can promote environmentally friendly practices and also ensure that fishing communities and local businesses maintain and grow their market for the sustainable fish they supply.



Wild Fish

One Source Proteins sources wild fish caught using the most sustainable methods and the best techniques possible to catch the targeted fish, versus those not targeted. This includes traditional pole and line or hand line fishing which also ensure that unwanted by catch is largely avoided. This approach to sustainable sourcing includes sourcing from fisheries that operate within respected management programs and, wherever possible, we work with fisheries certified to the MARINE STEWARDSHIP COUNCILS environmental standard for well managed and sustainable fisheries.

Our commitment to sustainable sourcing is also reflected in our ongoing research which aims to develop sales and consumer demand in a wider range of lesser known, but highly sustainable over abundant species.

Farmed Fish

We source our farmed fish from small scale farms whose products are well handled and fully traceable. Our farmed fish supplier partners adhere to standards that assure both quality of product for our customers and support the welfare of the fish stock and the surrounding environment.
