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.

Leaders in environmental consulting @PLANCTON_ANDINO (Chile) have been using a @Chelsea_CTG  Act2 #frrf3 to monitor red tides as part of the Bivalve Molluscs Health Program.

Leading environmental consultants Plancton Andino SpA (Chile) are using a CTG FastAct Laboratory FRRf System to monitor red tides as part of the Bivalve Molluscs Health Program.

Chile is the world’s fourth largest producer of mussels and the health of the mussels is of paramount importance to the economy. These “red tides” or Harmful algal blooms (HABs) are natural events occurring around the world. Since first being reported in Chile in 1972 in the Strait of Magellan these HAB have increased in both frequency and geographic coverage.

CTG Algae-Wader Pro systems for Flanders

The Flanders Environment Agency (VMM) has taken delivery of a number of CTG ALGAE-Wader Pro systems to assist 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.

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.
