Reducing Aquaculture Die-offs, in Real-Time

Last year, Atlantic Sapphire lost 250 tonnes of salmon in a mass die-off due to hydrogen sulphide poisoning from accumulated organic matter, an all-too-common problem in aquaculture with significant economic losses. Growing salmon in land-based tanks in which water is continuously circulated can cause sporadic toxic microorganism outbreaks that cause costly mass fish stock die-offs. Trials have began, using the CTG BACTI-Wader Pro, with the aim of providing a real-time alert system, that gives enough warning time for operators to respond and avoid a potential toxic bacteria outbreak.

Great News! I am delighted to announce that Bethany Fox successfully defended her PhD thesis titled “Bacterial processing of fluorescent dissolved organic matter in freshwater”. Bethany's PhD was a CASE Award based at the University of the West of England under Professor Darren Reynolds, funded by NERC and Chelsea Technologies Group (CTG).

Great News! We are delighted to announce that Bethany Fox successfully defended her PhD thesis titled “Bacterial processing of fluorescent dissolved organic matter in freshwater”.  Bethany's PhD was a CASE Award based at the University of the West of England under Professor Darren Reynolds, funded by NERC and Chelsea Technologies Group (CTG). 

Throughout the PhD Bethany has undertaken secondments at CTG and will continue to work with us as part of her post-doctoral research. This 3-year project, also based at the University of the West of England and led by Professor Reynolds, is funded by NERC and the Newton-Bhabha Fund in a joint initiative focused on water quality in India. Well done Beth and Congratulations.

CTG Algae-Wader Pro systems for Flanders

The Flanders Environment Agency (VMM) have taken delivery of a number of CTG ALGAE-Wader Pro systems to assist them in their work in assessing Algae levels within the water environments within Belgium.  CTG’s representatives within the Benelux countries, Notra BV, assisted in arranging the demonstrations and the subsequent supply.

The systems supplied to VMM are configured for measurements of Chl-a, Phycocyanin and Phycoerythrin and come with a handheld unit which provides both graphical and digital real-time data to the operator, with Red, Amber, Green thresholding, and logs the data for post mission extraction.
