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 …

Oyster Culture

 

Oyster culture is one of the most prominent forms of marine aquaculture in the U.S. In 2011 31 million pounds of oysters were harvestede with a dockside value of approximately $135 million (National Marine Fisheries Service). That is probably a low estimate of the overall value of the oyster because it does account for the ecological value of the fish species that use oyster reefs as a food source and nursery habitat, nor the coastal protection and water-quality …
