BioFishency, a provider of electro-chemical and biological water treatment solutions for RAS, announced the first-ever MIB and geosmin removal from water and fish tissues, eliminating off-flavors in trout.
The company, in collaboration with the Technion – Israel Institute of Technology, performed multiple tests to determine BioFishency ELX™ system's removal of MIB and geosmin. Testing at BioFishency's R&D RAS facility confirmed the world's first-ever removal of MIB and geosmin in fish while feeding and maintaining fish growth.
An advanced electro-chemical water treatment system, BioFishency ELX outpowers biological RAS, all in a fully controlled environment, while eliminating off-flavors. Ideal for cold and warm water species, the multi-stage, single cycle solution transforms ammonia to nitrogen gas, supports a small carbon footprint, requires less space and energy, and operates immediately on power-up.
BioFishency co-founder & CTO, Igal Magen, said that “off-flavors significantly impact fish quality and value, where BioFishency ELX has proven successful in their removal. Traditional biological RAS, purging under starvation, consumes vast amounts of water, while growers lose ~5% in fish weight, lowering market value. BioFishency ELX presents RAS farmers with a sustainable, cost-saving solution that enables fish welfare, and normal growth during purging.”
Proessor. Ori Lahav and Raz Ben-Asher, Technion Faculty of Civil and Environmental Engineering, confirmed that MIB and geosmin can be eliminated with BioFishency ELX in less than ten days. During the testing, fish were exposed to water spiked with high levels of MIB and geosmin, with BioFishency ELX introduced during purging while feeding.
"In seven days, MIB was not detected in the fish flesh, and within ten days, geosmin was fully removed from the skin and muscles – extraordinary, never seen before results. We look forward to additional BioFishency ELX testing on salmon by globally-acclaimed Yonathan Zohar, Professor & Chair, Department of Marine Biotechnology, UMBC,” said Lahav.
