Areas of Specialization/Research
My main areas of interest in aquaculture center on water conservation and water quality. Examples are: quantification of water use based on farmer surveys and prediction of water use from the water discharge models I developed during my thesis research; development of a water model able to predict regional crawfish pond water use based on climate data (e.g., the multivariate El Niño Southern Oscillation index); utilization of filtration systems (natural or mechanical) to reduce solids and nutrients; implementation of BMPs that can reduce water use and discharge (i.e. modifying pond storage capacity, final drawdown practices, and receiving ditches). My ultimate goal is to find the optimum in BMPs that will allow for a reduction in water use and water discharge while still allowing for the highest possible crawfish yields. |
Professional Experience
1. Quantify the solids and nutrients within crawfish effluent from commercial crawfish farms in the Cole Gully sub-watershed (which is located within the Bayou Plaquemine-Brule watershed) and to determine the effect of effluent on stream water quality.
2. Evaluate BMPs for crawfish ponds.
3. Develop water budgets for crawfish farms in south-central and southwest Louisiana.
4. Quantify water discharge for crawfish farms in south-central and southwest Louisiana.
5. Quantify the area and the amount of crawfish farms in south-central and southwest Louisiana.
6. Educate and inform producers and regulators on the characteristics and management of effluents from crawfish ponds.
7. Summarize findings in forms needed for development of a watershed-scale BMP implementation plan.
