USDA 8 Milestones

Overcome obstacles associated with large-scale culture tanks

• Develop practices to control water velocity and solids flushing in large and deep culture tanks.
• Develop a fish herding technique to improve fish transfer and harvest
• Determine the effect of noise on fish cultured in controlled intensive aquaculture systems
 

Develop unit processes to improve production system water quality

• Evaluate advanced oxidation with ozonation and ultraviolet irradiation to disinfect recirculating water flows in aquaculture
• Study rainbow trout health in high feed/low flow controlled intensive aquaculture systems
• Compare carbon dioxide stripping in freshwater and marine controlled intensive aquaculture systems
• Evaluate a novel oxygen absorber and carbon dioxide scrubber to control gas concentrations and save energy in controlled intensive aquaculture facilities
 

Treat solids and nutrients in aquaculture effluents

• Optimize solids capture and dewatering in geotextile tubes
• Evaluate a membrane biological reactor for removing nutrients from aquaculture system backwash
• Develop a geotextile filter in a biological treatment systems to capture and treat biosolids and nutrients in an aquaculture effluent
 

Mitigate impact of feed on effluent quality
• Conduct trials on waste production and fish performance when fed grain-based diets
