New technology has been released designed to improve fish attraction and passage at dam facilities by efficiently supplying stable, dissolved oxygen throughout fish passageways.
MSD Animal Health, a division of Merck & Co., Inc., Kenilworth, N.J., USA (NYSE:MRK), has launched Hyper InfusiO2n solutions, designed to deliver oxygen directly into water – making it immediately available for fish respiration by simultaneously removing other dissolved gasses at an approximate one-to-one rate. Consequently, oxygen supplied by the Hyper InfusiO2n solutions stays dissolved for longer, particularly in turbulent environments such as fish ladders.
“Our Hyper InfusiO2n solutions were developed to ensure sustainable hydropower operations while also supporting fish populations,” said Kasha Cox, global aqua commercial leader, MSD Animal Health. “This is a critical component of our environmental sustainability mission, and we are thrilled to bring novel solutions to conservation and hydropower communities.”
In addition to optimizing passage environments, the company’s Hyper InfusiO2n solutions have been designed to improve attraction to fish ladder entrances by creating a downstream plume of infused oxygen.
“Our Hyper InfusiO2n solutions can achieve unprecedented levels of oxygen concentration – up to 442% – without significantly altering total gas pressure, providing an additional tool to improve fish attraction and passage,” said Chris Beasley, aqua innovation lead for MSD Animal Health. “In one pilot application, fish passage increased more than 1200% over a four-year period following installation. The high oxygen transfer efficiency and durability of our Hyper InfusiO2n solutions also decreases operating costs and promotes long-term hydropower sustainability. Also, taking a One Health approach, MSD Animal Health is working with hydropower and energy companies to have a positive impact on fish health and well-being – as well as on the sustainability of our environment.”
The company’s Hyper InfusiO2n solutions are now available in a range of modular, scalable applications that can be customized to a variety of fish passage designs.
