Research Project:
OPTIMIZING CATFISH/WATER QUALITY INTERACTIONS TO INCREASE CATFISH PRODUCTION
Location: Catfish Genetics Research
Project Number: 6402-13320-003-00
Project Type:
Appropriated
Start Date: Dec 14, 2004
End Date: Dec 13, 2009
Objective:
The objectives are to: 1)Discover, develop, and apply methods to predict off-flavor episodes and manage off-flavor compounds; 2)Identify optimal water column conditions for balanced growth of bacteria, phytoplankton, and zooplankton resulting in reduced secondary metabolite formation, and enhanced fish survival and production; 3)Determine influence of chemical and biological factors on channel catfish respiration, growth and produciton, and develop and test management methods to minimize limits on production; and 4)Develop new equipment and technologies to improve profitability of channel catfish farming.
Approach:
Techniques will be developed to use hand-held as well as airborne imaging systems to identify/quantify cyanobacteria in ponds; algal culture will be used to determine possible control measures for harmful algae; laboratory respirometry and small pond production studies will be used to determine impacts of various water quality parameters on growth and production of catfish; the Aquascanner Sonar will be further developed to provide an accurate inventory of mixed-size catfish populations in large commercial ponds; high potential management applications and equipment will be tested in ponds and tanks on the Thad Cochran National Warmwater Aquaculture Center, and in commercial catfish ponds of cooperators.
