AquaFish Director, Hillary Egna, has partnered with faculty from the Oregon State University Biological and Ecological Engineering Department over the last three years to provide students real-world experience solving a challenge facing small-scale fish farmers - maintaining optimal oxygen levels in their fish ponds. Electricity needed for pond aeration can be unreliable and oxygen naturally depletes in ponds overnight. To address these issues, students were tasked with designing low-cost, durable, and practical aerators powered by the sun to provide consistent oxygen to ponds. Each year, students improve aerator functionality and build upon the innovations of previous students. Select students traveled to Ghana to field test their prototypes in existing ponds of AquaFish partners at Kwame Nkrumah University of Science and Technology.
