A recent research study found success in testing various soy-based diets for use in tuna farming and ranching.
Alejandro Buentello of Ichthus Unlimited, LLC presented the results in last month's Offshore Mariculture Conference in Mexico through the video "Feeding Bluefin."
The Illinois Soybean Association checkoff program funded the feed research.
"The successful research results should help provide permanence to tuna aquaculture, and can become the platform upon which commercially manufactured tuna feeds can now be developed," said Buentello.
A diet was successfully tested on ranched Pacific bluefin tuna in ocean net pens off the northwest coast of Mexico. The measured feed conversion ratio (FCR) of normal bluefin is 28:1. The new soy-based diet is 4:1.
