Algal And Bacterial Nitrogen Processing In A Zero-Discharge Suspended-Culture Shrimp Production System, Christian-Dominik Henrich
All Theses
The objective of this research was to further modify and develop the Clemson Partitioned Aquaculture System (PAS) design resulting in a system design capable of yielding economic feasible production rates of marine shrimp, Litopenaeus vannamei, in excess of 45,000[kg/ha] (40,000[lb/ac]) within a 5 month culture period while minimizing impact on the surrounding environment. The operation of the pilot-scale high-rate prototype shrimp culture system showed that it is possible to combine chemoautotrophic and photoautotrophic processing of feed and waste products within the system. A total of 23,400[kg/ha] (20,800[lb/ac]) were harvested at the end of the season (149 days from PL-8/9 shrimp …

Twenty midlactation Holstein cows (4 ruminally fistulated) averaging 101 ± 34 d in milk and weighing 674 ± 77 kg were used to compare rations with brown midrib corn silage (bm3) to rations with dual-purpose control silage (DP) on N utilization and milk production. The effect of monensin in these rations was also examined. Animals were assigned to one of five 4 × 4 Latin squares with treatments arranged in a 2 × 2 factorial. Cows were fed 1 of 4 treatments during each of the four 28- d periods. Treatments were 1) 0 mg/d monensin and bm3 …
