“…Catfish and paddlefish survival was greater than 80%, and tilapia survival was not calculated as males and females continued to spawn throughout the production season (Brown et al ). Survival rates of 54–86% have been observed for catfish in in‐pond floating raceways (Hawcroft ; Bernardez ; Martin ; Wilcox ), although Masser and Lazur () observed catfish survival as high as 98% for in‐pond raceways under research conditions.…”

“…Survival was estimated by dividing the number of fish harvested by the number of fish stocked and multiplying that value by 100. Brown et al () previously described detailed fish production methodology using an in‐pond raceway system.…”

“…Most farmers have adopted the more simplified split‐pond design, although some use in‐pond raceway systems (Brown and Tucker ). In‐pond raceways consist of multiple fixed or floating fish culture units normally in a parallel configuration, in which water is circulated between the pond and raceways using slow‐rotating paddlewheels, large airlift pumps, or a combination of the two (Brown et al ; Brune et al ; Masser ). So far, results have been impressive, with production rates exceeding traditional pond catfish culture by up to four times the average amount harvested (Brune et al ).…”

Intensive production of ictalurid catfish in the USA has increased over the past several years, and a better understanding of the amount of organic carbon (OC) and dissolved oxygen (DO) in these culture environments is needed. Budgets for OC and DO were estimated over a production season (March to November) for an in‐pond raceway system for channel catfish, Ictalurus punctatus, and hybrid catfish (channel catfish × blue catfish, Ictalurus furcatus), with co‐culture of paddlefish, Polyodon spathula, and Nile tilapia, Oreochromis niloticus. Feed input ranged from 45 to 263 kg/ha/d with an overall average of 80 kg/ha/d. Production of each kilogram of live catfish required 1.5 kg of feed and released into the water 0.70 kg of OC, and led to the synthesis of an additional 3.36 kg of OC by photosynthesis. Consequently, production of 1 kg of live catfish resulted in 4.06 kg OC, and harvest of catfish accounted for only 29.5% of OC applied from the feed. Removal of OC increased to 34.3% with the additional harvest of paddlefish and tilapia. OC was consumed in respiration, and some OC accumulated in sediment. Total respiration within the system exceeded the DO produced by photosynthesis, while diffusion and mechanical aeration aided in maintaining suitable DO levels for fish production.

“…New production technologies that are functionally hybrids among pond, raceway, cage, and water reuse systems include the in-pond raceway system (Brown et al 2011) and the partitioned aquaculture system (Brune et al 2003). Fish are held at high density in floating raceways through which water is flushed by paddlewheel aerators or air-lift pumps.…”
