Protein-rich bacterial biomass as a fishmeal substitute: a sustainable alternative in fish feed
In modern aquaculture, protein-rich bacterial biomass is becoming increasingly important as a fishmeal substitute. Although fishmeal continues to be a high-quality and proven protein source, there is growing interest in alternative raw materials that can fulfil certain requirements even more specifically – whether from an ecological, technical or economic perspective.
Why fishmeal should be supplemented or replaced
Fishmeal provides an ideal amino acid spectrum, is highly digestible and has been used successfully in fish nutrition for decades. It remains a first-class component of many feed formulations. Nevertheless, ecological, price and ethical requirements are increasing – not every farm can or wants to rely on fishmeal in the long term. It is therefore worth knowing about alternatives that may be equivalent or even more favourable under certain circumstances.
Protein-rich bacterial biomass as a fishmeal substitute in aquaculture
Bacterial biomass as a fishmeal substitute offers exactly this possibility: a flexible, sustainable supplement or even a complete replacement. This protein source is produced from bacterial fermentation by Corynebacterium glutamicum, which is
100% non-animal origin and provides highly digestible and flavourful proteins. The result is a highly concentrated protein product with a consistent nutritional profile and good digestibility.
This biomass is an interesting option for growers who want to work independently of marine resources or are looking for alternatives due to regulatory requirements.
Advantages of protein-rich bacterial biomass as a fishmeal substitute
The use of these kind of protein offers various advantages:
It protects marine fish stocks, enables the utilisation of organic side streams and improves the predictability of feed production. This approach is particularly attractive for farms with clearly defined sustainability goals.
Studies show that many fish species can utilise this protein source very well. Bacterial biomass is also easy to integrate in terms of flavour and technology. Its production is independent of catch quotas or seasonal fluctuations – an advantage for globally active producers.
Open questions and individual requirements
Despite convincing arguments, it remains to be said: There is no one right solution for everyone. Depending on the type of fish, production system, regional conditions and customer expectations, both fishmeal and an alternative such as bacterial biomass can make sense. Our conviction is therefore not ‘either or’, but ‘both’ – always adapted to the specific requirements of our customers.
Conclusion
Protein-rich bacterial biomass as a fishmeal substitute is an exciting addition to proven raw materials. It opens up new avenues for sustainable growth in aquaculture without jeopardising the value of fishmeal.
