Project description
CLEAN ENERGY SOLUTION
The proposed solution is a new aeration method that does not require electricity, has few maintenance requirements with no moving parts, and is inexpensive to fabricate and deploy in LICs. The system uses heat that is captured through a solar thermal absorber plate and transferred to the bottom of the pond to heat the bottom water. The heated water will rise and mix the pond, spreading oxygen-rich water from the top through the entire depth of the pond. This increases the DO reservoir and can result in improved water quality and higher pond yields.
IMPACT
The system will allow for increased density of fish stock, higher yields of fish, as well as larger fish that have a higher market value and demand. Fish feed is also used more efficiently, which reduces feed and operation costs. The solution is an alternative to power-hungry aeration systems that consume a significant amount of energy and capital. For farmers not using aeration, the technology will provide all of the benefits described above. For farmers using aeration, replacing or supplementing existing devices can greatly decrease energy consumption for aquaculture.
ORGANIZATION
The University of Toronto will oversee a small team conducting research focused on design, and analysis of the new aquaculture aeration technology. The University of Toronto has partnered with Curiositate to provide industry feedback and consultation throughout the development of the technology. A partnership has also been formed with BRAC for field trials and planning for technology scale-up.
University of Toronto (Canada) participated successfully in the PAEGC Initiative (https://poweringag.org/) and was with its project 'Field Evaluation of a Passive Aeration System for Aquaculture' in Bangladesh among the winners of 2015
