The burgeoning fields of aquaculture and aquaponics hold vast potential for growing food. Yet, the efficacy of these microbial-mediated processes is governed by the availability of dissolved oxygen in water. Generally, oxygen has poor solubility in water, which has a negative effect on fish growth and plant yields. <\/p>\n

Almost $200,000 in new funding from the USDA<\/abbr>-National Institute of Food and Agriculture\u2019s (NIFA<\/abbr>) Water Quantity and Quality Program may expand researchers’ understanding of how nanobubbles could improve aeration and oxygen supplies. Under the grant, Samir Khanal<\/strong> of the University of Hawaiʻi<\/span> at M\u0101noa\u2019s College of Tropical Agriculture and Human Resources (CTAHR<\/abbr> ) Department of Molecular Biosciences and Bioengineering<\/a>, will apply the technology to these aqueous systems. His goal is to uncover new opportunities for improving fish and plant yields\u2014with concomitant improvements in water quality. <\/p>\n

“There is a pressing need to develop an alternative to the current highly energy-intensive conventional aeration,” said Khanal. “Nanobubble technology has a potential to revolutionize aquaculture and aquaponic systems, with higher productivity and resource recovery.”<\/p>\n

Khanal was initially awarded CTAHR<\/abbr>\u2019s Team Science grant, which was critically important to obtaining preliminary data for his grant proposal to NIFA<\/abbr>. <\/p>\n

“Thanks to the CTAHR<\/abbr> and NIFA<\/abbr> grants, we hope our findings will benefit existing Hawaiʻi<\/span> businesses, as well as a new generation of growers, across the state and beyond,” Khanal added. <\/p>\n
