Castell Salmon From Our Farm to Your Table
Atlantic Salmon (Salmo salar), which will be farmed sustainably and responsibly in Germany without antibiotics or GMOs.

Why Salmon?
Castell Salmon is built on the site of a long-established trout farm in Griestal. The decision to transition from trout to Atlantic salmon was based on four clear factors.
SALMON IS A NATURAL SUPERFOOD
Salmon provides high-quality, easily digestible protein. It delivers omega-3 fatty acids (EPA and DHA), which support heart, brain, and eye function. It also supplies essential vitamins such as B12 and D, along with minerals like iodine and selenium.
- ProteinsEasily digestible, high-quality nutrition with taurine.
- Omega-3Deliver EPA and DHA in high amounts.
- VitaminsStrong sources of B12 and D.
- MineralsProvide iodine and selenium.

MORE CLIMATE-FRIENDLY THAN OTHER ANIMAL PROTEINS
Compared to chicken, pigs, and cows, salmon farming achieves a more efficient use of resources and leaves a smaller footprint.
- Feed EfficiencyProduces more edible meat from the same feed.
- Carbon EmissionsLower than those of chickens, pigs, and cows.
- Water UseRequires far less water.
- Land UseNeeds much less land.

A LOCAL, SUSTAINABLE CHOICE
Salmon is one of the most popular fish in Germany. By producing salmon locally in a land-based system, we will reduce imports and avoid the environmental impacts of traditional sea-cage farming.
- Environmental ProtectionNo sea-lice, no seabed pollution, no antibiotics, no pesticides.
- Local ProductionWill reduce imports and strengthen regional supply.
- Transport RoutesWill avoid long-distance shipping and lower emissions.
- TraceabilityFull control and transparency from source to customer.
