The Company MOHNEN aquaculture

Your competent partner for fish farming, delivery, processing and preparation

As the largest fish farming business in the German federal state of North Rhine-Westphalia, our family company is known for its reliability and high quality. The crystal-clear water from the Eifel uplands that is used in our ponds as well as our fishing expertise also contribute towards our company’s excellent reputation.

Our customers can purchase trout, salmon trout and many other live fish. We also offer fresh and smoked fish for wholesalers, retailers, restaurants and caterers. Our fish shops in Eschweiler-Weisweiler and Stolberg-Gressenich additionally stock specialities such as smoked fish platters and a small range of fish salads, seasonings and wines to choose from. On top of all this, we also have two idyllic fishing parks in the northern part of the Eifel region, where you can fish in a peaceful setting all year round..

Our fish farm was awarded the „NRW isst gut“ (“North Rhine-Westphalia eats well”) award for high-quality local food products in 2018. The award not only examines product-specific criteria but also checks and certifies the company’s special connection with the local region. As one of the largest aquaculture businesses in Germany, we are committed to the region, uphold transparency in the value chain, take responsibility for the local living and economic environment and are a fair and cooperative employer.

MOHNEN History
MOHNEN Sustainability


We always strive to ensure that the management of our pond systems is as sustainable as possible. In addition to our gentle farming activities and the integration of our fish farming into the local ecosystem, processing and preparation also play an important role in this approach…
