The main bottleneck to further development of sustainable and intensive aquaculture in Midwest is improvement of larval fish rearing technologies and larval fish nutrition. The main objective of this project is to develop detailed protocols for larval largemouth bass rearing in indoor facilities that will help to support high survival and growth performance of this species in its young age.

New Approach in Replacing Live Food – Meeting Largemouth Bass Larvae Growth Requirements using Asian Carp Muscle as an Initial Protein Source
The objectives of this project are:
- To develop optimal in vitro methodology for Asian carp muscle hydrolysis using largemouth bass (LMB) endogenous digestive enzymes obtained from adult LMB.
- To evaluate the effect of Asian carp muscle protein hydrolysates obtained using methodology in Objective 1 as a first feed for larval LMB.
On the feasibility of establishing a saline aquaculture industry in Illinois
- Determine the existing and near-term (5-10 years) market for striped bass species in the Midwest region of the US for food consumption
- Analyze the competitive advantages of rearing a euthyhaline species (Striped Bass) in Illinois/Midwest using regional saline water resources
- Locate appropriate saline water resources in Illinois and examine water quality for compatibility with striped bass production
