Monitoring Bacteria in Recirculating Aquaculture

“Last year, we entered trials with NUI Galway, supplying our BACTI-Station Pro system for monitoring bacteria in Perch aquaculture,” said Sam Kirby. The project is in collaboration with the Technical University of Denmark (DTU), Bord Iascaigh Mhara and Keywater Fisheries.

FluoRAS, Horizon 2020 COLUMBUS and EMFF ECO-AQUA are putting in place aquaculture trials of a fluorometer sensor system to categorise and quantify different types of organic matter which accumulates in closed systems. The initial trials, using BACTI-Station Pro, will aim towards a real-time alert system that gives enough warning time for operators to respond and avoid a potential toxic bacteria outbreak.

Initial tests have been conducted in ponds, indoor recirculating aquaculture systems tanks and an influent source, revealing consistent levels of coloured dissolved organic matter (CDOM), but highly variable Tryptophan-like-fluorescence, probably due to differences in stocking densities, stock sizes and treatments. Follow-up trials are due to be conducted, drawing comparisons between in situ sensor readings and sample analysis in the laboratory. The project aims to monitor bacterial populations in recirculating aquaculture systems in an attempt to reduce mass mortality events and help to improve energy savings by informing site operators on required UV dosages.

This work has been carried out as part of the ECOAQUA project which received funding under the European Maritime Fisheries Fund, administered by Bord Iascaigh Mhara, through the Knowledge Gateway Scheme, on behalf of the Department of Agriculture, Food and the Marine.
