Research Focus

• As Coordinator for Aquaculture Programs I am responsible for oversight of all aquaculture programs (research, extension, and education) at KSU. This includes coordination of schedules, allocation of physical resources, and maintenance and operations of the Aquaculture Research Center (ARC). Strategic planning and determination of overall program directions in consultation and cooperation with other research and extension scientists are other important responsibilities. Also, KSU now offers a Master of Science in Aquaculture/Aquatic Sciences. Information on the Masters program can be reached at http://www.dcr.net/~jtidwell.
• As one of the researchers at ARC my overall objective is to facilitate the development of aquaculture as a viable industry within the Commonwealth. My research is directed toward identifying culture species best suited for production and marketing within the region. Specific objectives include: 1) Evaluation and development of locally applicable culture methods for promising species that are readily utilized by average producers. 2) Development of practical diets for these species using locally available, and hopefully locally produced, ingredients (such as distillery by-products).  Species being evaluated include:

Primary efforts are being narrowed to freshwater shrimp and largemouth bass.

Current Projects

• Integration of Freshwater Prawn Nursery and Growout Systems Into Diversified Farm Systems
• Development and Refinement of Culture Procedures for Alternative Aquaculture Species in Kentucky
