Background information:

DECLEVA`S ALPENFISCH MARIAZELL has existed for over 10 years as a fish farm.


Crystal clear, cold mountain water - that is the source of life for our Mariazeller char and trout! In the middle of the Alpine Hochschwab massif, water flows into our organic-certified ponds. Fresh and natural, exactly this water supplies the Viennese households with its unique quality. An 6.5 ° C cold elixir of life, where our fish find the ideal conditions for their slow and healthy growth.

Because "Good things take a while" - and an excellent quality fish also needs his time!

Our char and trout have 2.5 to 3 years to grow with certified organic food and nutrients from natural stream water, until they finally reach their catch size and are distinguished with an incomparable, wholesome taste.

DECLEVA`S organic fish is a great, culinary catch for all health-conscious fish gourmets!
