Applying a Test Developed to Combat Obesity and Diabetes to Improve Growth in Fish, Mollusks, and Crustaceans.

Zebrafish have become an increasingly common model organism used in biomedical research to address human health issues.  Research performed in zebrafish may advance methods that can be applied to improve aquaculture.  In fact, a string of recent research aimed at better understanding obesity and diabetes is now being applied to improve selection for growth and feed conversion in commercial aquaculture species, including tilapia, oysters, and shrimp.   

While working at Vanderbilt University Medical Center, Dr. Benjamin Renquist was focused on identifying …

Aquaponics: Paradigm Shift with Airlift
With thoughtful design, appropriate maintenance, and effective management, airlift pumps may allow the transfer of water through an aquaponics system in a more efficient way than using water pumps. Understanding the disadvantages and learning how easy it is to construct an airlift pump can help many to reduce their energy cost while avoiding the high risk
