Project Number: 6402-13320-002-00
Project Type: Appropriated

Start Date: May 06, 2001
End Date: Apr 30, 2005

Objective:
The objectives are to: 1)Determine effects of sub-lethal oxygen concentrations & various other factors on catfish metabolism & respiratory efficiency; 2)Develop/test equipment & management practices to minimize oxygen stress and intensify production on warm-water fish farms; 3)Identify problematic algal species responsible for secondary metabolite production, including toxic & off-flavor compounds that impact catfish production; and 4)Identify techniques for controlling harmful algal blooms in aquaculture.

Approach:
Channel catfish and algal physiology and metabolic pathways will be determined and quantified using laboratory techniques such as respirometry and algal culture. Promising algal and water quality management techniques will be evaluated in Unit aquaria, tanks and ponds. High potential applications will be tested in production ponds on the Thad Cochran National Warmwater Aquaculture Center and in commercial catfish ponds of cooperators.
