Stembiont® Vital
Stembiont® Vital contains beneficial bacteria that occur naturally in the marine environment. These bacteria support essential biological functions and enhance fish health.



Strengthen fish health
In nature, fish live in close contact with a wide range of microbes. In today’s more sterile and industrialized hatchery production, fish are exposed to fewer bacteria.
Previwo’s research shows that early exposure to beneficial bacteria can help strengthen fish health throughout the entire life cycle.
Based on 10 years of research
Stembiont® Vital is the result of many years of research conducted by Professor Henning Sørum and his research group at NMBU
Application of Stembiont® Vital
Stembiont® Vital is supplied directly by Previwo. Please contact us for ordering and more information
Stembiont® Vital contains live bacteria and is primarily produced to order. To ensure reliable delivery, we operate with a four-week lead time from order placement, although we can usually deliver on shorter notice.
Stembiont® Vital contains live bacteria, and each batch has a shelf life of up to 12 weeks. Please refer to the expiry date on the label.
Stembiont® Vital should be stored at low temperatures, between 2°C and -15°C until use. Fine table salt is supplied together with Stembiont® Vital.
- Invert the bottle of Stembiont® Vital until all sediment is fully dissolved.
- Fill the anaesthesia tank to at least half capacity.
- Dissolve the salt in one or two buckets of water and add this to the anaesthesia tank. Salt is added because the bacteria in Stembiont® Vital require salinity; a minimum concentration of 1% must be achieved. It is therefore essential that the salt is added before Stembiont® Vital.
- Add Stembiont® Vital and then fill the rest of the anaesthesia tank with water.
- Ensure that the fish remain in the anaesthesia bath for at least 45 seconds to allow proper uptake. The recommended treatment time is 45–90 seconds.
- Use an opened bottle of Stembiont® Vital within 24 hours.
- At the end of the day, thoroughly rinse the anaesthesia tank with fresh water.
