My research program focuses on aquaculture and aquatic animal nutrition. We explore aquacultural opportunities for Indiana and other parts of the world and have worked with American lobsters, spiny lobsters, hybrid striped bass, yellow perch, bluegill, largemouth bass, walleye and tilapia. Our nutrition work focuses on new diets for established aquaculture industries and development of diets for emerging industries. We have been working on modified diets for rainbow trout and Atlantic salmon, as well as tilapia. New diets for yellow perch, hybrid striped bass and largemouth bass have been developed. Much of our work has been focused on replacing fish meal in diets. The global supply of fish meal has been at maximum sustainable yield for approximately 8 years, but demand continues increasing. We have been successful replacing fish meal with soybean meal in diets for yellow perch, and hybrid striped bass and are currently exploring use in largemouth bass. There is a need within aquaculture specifically and animal nutrition in general to develop diets rapidly. We are currently exploring use of two new scientific disciplines to understand nutrient needs and use of ingredients from diets. Combining metabolomics and proteomics provides us with a more complete view of metabolism. We are also using the combination of metabolomics and proteomics to understand flows of nutrients through food webs and applying this approach to both aquaculture and natural settings.
