Brief Project Summary:

The primary goal of this project was to determine the effectiveness of meal from two cultivars of Schillinger Genetics soybeans, the 3010 and Trifecta, as a substitute for fish meal in diets California yellowtail (YT; Seriola lalandi). YT is a highly valued commercial and sport fish in southern California and is considered an excellent food fish. HSWRI is currently culturing YT on an experimental scale but great potential exists to expand commercial culture in both northern Baja California, Mexico and Southern California. YT are in the family Carangidae or jacks – a group that typically requires high levels of high quality fish-based protein in the diet. The use of alternate ingredients...

Final Project Results

Updated February 21, 2021:
The results of the feeding trial showed that FM can be partially replaced with meals from both the SG 3010 and Trifecta cultivars. Growth performance decreased in fish fed diets with increasing inclusion of 3010 meal above 50% of the total protein although the fish fed the diet with 60% of the total protein coming from 3010 meal still performed better than the FM diet. Fish fed all three diets containing Trifecta meal performed at least as well as those fed the FM diet, with fish fed the diets with 50 and 60% of the total protein coming from Trifecta performing significantly better overall. Based on the data collected from these trials, the 3010 and Trifecta defatted meals are prime candidates for incorporation into production diets for California yellowtail.

Digestibility of meals from the two cultivars was not determined because we were unable to collect feces using the traditional method of abdominal massage. We determined that the unique gut morphology of YT prevented collection of feces in this manner. More research will be necessary to determine a practical methodology for collecting feces from YT.
The commercial growout trial was successfully launched. The results of that trial and the disease challenge research are outside of the scope of the research contract reported on here.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
