Chalkstream® is supplied by the only farms on the Test and Itchen rivers in Hampshire growing trout for the table. The farms are built on the sites of old water mills and benefit from exceptional volumes of pure chalk stream water flowing through a series of custom designed raceways, tanks and outlet streams.

The farms are gravity fed and the high flow design ensures the fish grow in a constant current mirroring the conditions of their natural habitat. Oxygen is added to the water periodically to mitigate the diurnal fluctuations in dissolved oxygen created by the vast quantities of river weed that grows in the rivers during the Spring and Summer months.

All the farms are fully segregated from the chalk stream rivers preventing wild fish from entering, minimising the risk of escapees and protecting the important river habitats. The water exiting the farms enters settlement channels or swirl concentrators which capture suspended solids and ensure the water is returned to the rivers in a favourable condition. The fresh water flow through design avoids many of the environmental concerns connected with open net farming.
