Used for fish production, recirculating aquaculture systems (RAS) rear fish at high densities in indoor tanks and offer a \u2018controlled environment\u2019. The systems continually filter, treat, and reuse water to increase the operational efficiency whilst simultaneously reducing risks from pollution and pathogens.<\/p>\n
The microbial health of the rearing water and biofilter of RAS is crucial for maintaining optimal water quality for land-based fish farms.<\/p>\n
Microbial communities that are operating at nominal capacity remove both organic and inorganic elements from the system.<\/p>\n
Ammonia, a toxic component for fish, is metabolised by specialised organisms called ammonia oxidising bacteria (AOB) and ammonia oxidising archaea (AOA), while organic substrates are degraded by heterotrophic bacteria. The production of toxic hydrogen sulphide, as well as off-flavour compounds such as geosmin, have been traced back to a microbial origin.<\/p>\n
As a result, the close interaction of the rearing water with the fish requires RAS operators to now get a firm grip on the microbial health of their systems.<\/p>\n
Thus far, the vast diversity and complexity of microbial life, combined with a lack of available measurement and software technologies, has precluded the development of toolboxes to manage these systems towards optimal operational performance.<\/p>\n
Located in Bergen, at the heart of the aquaculture industry in Norway, RASLab offers state-of-the-art research facilities for research into sustainable land-based fish farming. The organisation focuses on recirculating aquaculture system technology to transform the future of fish farming.<\/a><\/p>\n Now, RASLab has partnered with microbiome technology start-up KYTOS to offer commercial services to manage and optimise the microbial health and performance of RAS systems.<\/p>\n KYTOS offers a unique quantitative overview of the microbiome in the water and biofilter through its RASCheck, RASScreen, and RASManage service programmes that complement RASLab\u2019s RASseq services where next-generation sequencing identifies all of the bacteria in the biofilter.<\/p>\n By undertaking these combined analyses, it becomes possible to understand how microbiome management decisions affect the biofilter in terms of performance and resilience, as well as the total microbial environment of the recirculating aquaculture systems.<\/p>\n Using this information, bespoke services can be offered for optimising system and fish performance. Starting this August, RASLab customers can benefit from these combined.<\/p>\n Ruben Props, Co-founder and CEO of KYTOS, said: \u201cWith RASLab, we have identified a great commercial and R&D synergy for our RAS services. This collaboration aids us in fulfilling our core mission of making microbiome management tools smarter and more accessible to the industry.\u201d<\/p>\n Mark Powell, CEO of RASLab, said: \u201cOur RASseq services are complemented by the KYTOS toolbox. This collaboration fits in nicely with our provisions of microbial and lab support services to the industry and our research customers and is yet another part of how we drive for \u2018innovating the future of aquaculture.\u2019\u201d<\/p>\n Alongside the disease-bearing microorganisms, it is also essential to monitor the microbiome health from the beginning of the crop to take timely intervention to prevent microbial dysbiosis.<\/p>\n Both RASLab and KYTOS specialise in state-of-the-art microbiome technologies and recirculating aquaculture systems.<\/p>\n KYTOS uses Big Data and Artificial Intelligence (AI) to reduce aquaculture\u2019s unpredictability by creating practical tools that help make informed management decisions. Its services leverage flow cytometry, which is the most performant single-cell technology available today.<\/p>\n This high-throughput technology can analyse thousands of cells per second and measures detailed characteristics of each cell. KYTOS\u2019 powerful proprietary algorithms deliver a comprehensive report of the microbiome characteristics. Its KytoApp cloud-based platform collects these insights and makes them readily accessible to its customers.<\/p>\n <\/p>\n Today, KYTOS technology can already characterise most of the microbial life (fungi, bacteria, and algae) in the water, sediment, and fish of a farm. Functional indicators, devised using Machine Learning, connect these data to farm actions such as water maturation, disinfection efficacy, and nitrifier activity.<\/p>\n Complementary to KYTOS\u2019 functional approach, RASLab\u2019s RASseq service targets the genetic information of the microbiome to obtain detailed information about the bacterial community. Previous work has already shown significant differences in nitrifier communities between RAS systems operating under different salinities.<\/p>\n RASLab\u2019s unique and modular infrastructure enables the development and testing of new microbial health indicators. With 12 independent small-scale RAS systems and a stock of three (fully sequenced) biofilter options (freshwater, brackish water, and full seawater), RASLab can offer studies of the microbial environment from 5-30\u00b0C for any Norwegian aquaculture species.<\/p>\n Combined with KYTOS and RASlab\u2019s RAS and lab services, this powerful combination of microbiological tools for monitoring both fish health and RAS system performance will enable both companies to test new microbial health indicators for recirculating aquaculture systems.<\/p>\n KYTOS will work closely with RASLab to service farm customers via routine full-service programmes, which means that bespoke sampling programmes will be implemented, and all sampling materials and sample logistics are arranged.<\/p>\n <\/p>\n The KytoVial<\/a> sampling system enables biosecure microbiome sampling of the farm. The KYTOS AI engine will process the microbiome data to provide clients with rapid results of up to ten microbiome health indicators.<\/p>\nComprehensive microbial health assessments for RAS management<\/h3>\n
