KYTOS teamed up with Aqua Pharma Group this week at Aqua Nor to showcase Seatru, a commercial platform to bring precision microbiome management to aquaculture! Nico Boon and Ruben Props attended and also gave a presentation in the scientific session. More information available here: https://aqua-pharma.com/seatru/
Kytos has been selected for the EIT food accelerator network as part of batch #4!
Ruben will be moderating a discussion between some of the leaders in aquaculture microbiome management June 14th, organized by Hatchery Feed & Management.
A great collaboration with INVE aquaculture, Benchmark’s Advanced Nutrition group, and Jasmine Heyse (PhD candidate at CMET) resulted in novel insights into the way microbial communities assemble, and are influenced by artemia-, algae-, and dry feed-associated microbiomes, in shrimp hatchery systems.
In this study, we found that the microbial community assembly in the hatchery rearing water over time was dominated by stochastic effects. This demonstrates that random fluctuations in growth and death of bacterial species cause microbiomes in identical shrimp tanks to become more dissimilar over time. Two major shifts in microbial community structure that were tightly coupled to the abundance of Chaetoceros algae were observed. Using a newly developed source tracking algorithm we could quantify that 37% of all bacteria in the hatchery rearing water were introduced either by the live or dry feeds, or during water exchanges. The contribution of the microbiome from the algae was the largest, followed by that of the Artemia, the exchange water and the dry feeds.
These findings have significantly improved our fundamental knowledge on the assembly processes and dynamics of rearing water microbiomes and illustrate the crucial role of the peripheral microbiomes in maintaining health-promoting rearing water microbiomes.
Nico, professor at CMET – Center for Microbial Ecology and Technology and our KYTOS thought leader, provided some context on our journey from academia to spin-off in an interview with the fishsite.
His main take-away: “In the very near future we will be able to translate these complex microbial fingerprints into specific management advice that empowers farmers with actionable microbial management“
Ruben and Jasmine Heyse, PhD candidate at Ghent University discuss the limitations and knowledge gaps in microbial ecology in shrimp aquaculture in the 2019 issue of HatcheryFeed (volume 7, issue 4). They argue that the establishment of effective and sustainable microbial management strategies would be greatly accelerated by increasing our knowledge regarding the microbial ecology of these systems. A concerted effort among both industrial stakeholders, who have access to diverse aquaculture platforms, and academic partners, who have access to the know-how of next-generation technologies, is paramount to revolutionize the fundamental basis on which aquaculture microbiome management must be based.
