Description of Research and Extension Interests

I conduct research in channel catfish nutrition to address the need for more efficient feeds which also improve the health of fish, pond water quality and use in irrigation, and biological control of parasitic diseases.

Projects involve channel catfish, hybrid catfish, planktivorous fish, freshwater prawns, and white legged shrimp. Natural resource conservation projects include Suwannee bass reproduction for stock enhancement, pond water quality related to cyanobacteria toxins, and invasive aquatic species issues. I have Extension programing responsibilities for aquaculture management, aquaculture development, disease diagnostics, sport fish pond management, and aquatic weed control.

Courses Taught
