KE-fish - supplementary feed for fish

KE-fish is a feed supplement that contains the natural plant biology of herbs. KE-fish contains the ingredients of the herbs as well as their biology.


The main task of KE-fish is the positive effect on the metabolism and digestion of the fish. Scientific studies as well as applications in practice have shown that KE-fish as an addition to the daily feed has positive effects.


Mode of action of KE-fish:

The biology contained in KE-fish regulates the intestinal flora of the fish and acts as a natural antagonist of pathogens in the digestive tract of fish. The effect is based on a germ competition against unwanted bacteria by promoting wanted germs of the intestinal flora and inhibiting unwanted ones.


As supplementary feed for fish:

  • Reduction of feed consumption or better feed conversion
  • Higher resistance to parasites, harmful germs and fungi
  • Healthier vital fish stock through strengthened immune system
  • Firm meat consistency and meat quality
  • Longer shelf life of fish products

In fish ponds and fish tanks:

  • Faster decomposition of faeces
  • Reduction of algae, rot and harmful germs
  • Reduction of cleaning costs

Application and dosage in feeding:
100 ml KE-fish on 25 Kg pellet feed. Simply spray over the feed and mix.

Application and dosage in fish ponds and fish tanks:

Natural ponds and fish ponds: 100 ml per 10 m³ 1-2 times a year


KE-fish as alternative to disinfection:

KE fish can also be used as an alternative to disinfection. The biology contained in KE-fish acts as a natural antagonist of pathogens and displaces pathogenic germs (natural displacement competition!)


Cleaning of equipment, containers, nets, floors:

100 ml per 10 litres of water (approx. 20-25°C)


Quarantine tanks and in case of injuries:

1000 ml/10 m³ Then every 14 days or after a major water change 250 ml/ 10 m³


Fish live transport: 1000 ml/1 m³


Additive for fish eggs and brood

For bath without fresh water inlet: 200 ml/100lt brood water at least 1 hour

For continuous flow systems: 400 ml / 100lt fresh water

Unlike formalin, KE-fish is a natural product and causes no harm to either the brood or the fish.


Chronic diseases (viruses/bacteria/fungi), skin parasites

Cold water fish (trout, char, huchen, grayling, pure tench):

Short-term bath: 1000 ml/1 m³ (at least 1 hour)

Long-term bath: 100 ml/1 m³ (at least 1 day)


Warm water fish (carp, perch, sturgeon, catfish, tench, pike, eel):

Short-term bath: 500 ml/1 m³ (at least 1 hour)

Long-term bath: 50 ml/1 m³ (at least 1 day)

Research results:

Trial for the disinfection of fish eggs at the Federal Office for Water Management.


In this trial incubators were placed in a 150 litre basin. Each incubator was loaded with 150 g eggs (about 200 pieces) and the water was changed once a week. The eggs of five trout (Salmo trutta) were used, which were fertilized in 0.75% saline solution. From each egg sample 3 subsamples were used. Sub-sample 1 was incubated in water with 600 ppm KE-fish added. The water was changed once a week and at each water change the KE-fish was renewed. Subsample 2 was incubated in water to which no KE-fish was added. So the eggs were not disinfected. Subsample 3 was disinfected with 1000 ppm formalin once a week for 20 min. After disinfection the water was changed completely, so that no residues remained.

Studies on the optimised use of plant proteins in the diet of rainbow trout by the preparation KE-fish. In the present study the effect of the feed KE-fish was tested on rainbow trout fed with increased amounts of plant proteins with known negative health effects.


The targeted oral administration of 0.1 % KE-fish in the feed ration can compensate the negative growth effect of a plant-based diet for rainbow trout and achieve 16 % higher fish end weights.
KE-fish in a plant-based diet resulted in comparable growth performance and stress parameters to those obtained with a diet rich in fishmeal.

Field reports / customer feedback

In my 23 fish ponds, problems with fungal diseases (Saprolegnia) occurred again and again. Between 20 and 40 fish died daily from the fungal disease. On September 4th I started to mix KE-fish into the pellet feed. Already after one week less fungus-infested fish were visible in the ponds. On September 19th the health of the fish had already improved considerably and only 5 fish were found dead.  It became apparent that the current failures only affected fish already infected by the fungus. In mid-October I found only between 1 and 8 fish dead each week. I could not see any more fish with fungal diseases. Viktor Gusel, Austria

I have been using KE-fish in fish farming for 8 years now and I am totally enthusiastic about the effect. Fish diseases belong to the past. The fish grow more uniformly and are much more active, which is especially noticeable on hot summer days. In the beginning I was also asked by my customers (cooks) what I do differently now that the meat quality has increased. What I particularly like is that when cleaning the fish ponds there is now almost no more rottenness. Friedrich Ganser; Gaflenz - Austria
