A low-cost solar fish pond aerator designed by the University of Toronto could boost yields in most of the world’s aquaculture operations. Most artificial ponds worldwide are on family farms and other small-scale operations in developing countries.
A team at the University of Toronto has created a device that mixes pond water using heat from the sun. It requires no electricity, has no moving parts and can be manufactured and maintained locally from readily available parts. This device could put aeration in reach for impoverished farmers.
Dr. Amy Bilton of the University of Toronto made her presentation, Design of Appropriate Water and Energy Technologies for the Developing World at the Engineering for Global Development: Use-Inspired Solutions to Water-Energy Nexus Challenges event at Arizona State University.
University of Toronto discusses their plans to conduct a field evaluation of a solar-thermal passive aeration system for aquaculture in Bangladesh. This project has been selected for a 2015 Powering Agriculture Award.
