Brief Project Summary:

Use of soy-based products in practical diets for white seabass (Atractoscion nobilis) and California yellowtail (Seriola lalandi).

The overall objective of this project is to build demand for U.S. soy in aquaculture markets by developing soy based feeds for WSB and CYT. Both species are highly valued commercial and sport fish in southern California and are considered an excellent food fish. WSB commonly occur from northern Baja California, Mexico to Point Conception, California, USA. WSB and CYT have recently been provided to commercial growers, primarily in Mexico, as part of demonstration trials. The results from these trials have been very promising and both species are now appearing...

Information And Results
Project Deliverables

We identified another important finding for formulating soy-based diets for yellowtail relative to interactions between protein sources and taurine. Specifically, the protein source does not significantly affect the bioavailability of taurine. This will be used to help optimize diet formulations in the future.

We determined that seabass held in cages protected by predator nets keep stress at lower levels at baseline and they recover better from stress. There was a trend that the fish with predator nets had a more profound cortisol response when stressed. More research is needed to determine the broader consequences of these findings relative to justifying the use of predator nets in all situations.

We will disseminate the results of this research at the next WAS conference in early 2017.
