TLDR
A water recirculation system for the culture of the African catfish has been developed in relation to waste production and waste removal kinetics and it was found that ammonium removal by nitrification could be described by either 1 2 - order kinetics or 0-order kinetics, depending on the ratio of the concentrations of dissolved oxygen and ammonium.About:

Water quality requirements for reuse systems
TL;DR: Water quality criteria for aquaculture systems have typically considered parameters such as temperature, dissolved oxygen, total gas pressure, ammonia, and nitrite as mentioned in this paper, but these criteria may not be appropriate for a single species and life stage, especially in commercial applications.

Analysis of nutrient flows in integrated intensive aquaculture systems
TL;DR: Analyzing nutrient conversions, which are taking place in integrated intensive aquaculture systems, finds that fish culture alone retains 20–50% feed nitrogen and 15–65% feed phosphorous and the combination of fish culture with phototrophic conversion increases nutrient retention of feed N and feed P by up to 53%.

Biological filters in aquaculture: Trends and research directions for freshwater and marine applications
TL;DR: The implications of the changing use of recirculating aquaculture systems (RAS) on biofiltration research for freshwater and marine operations are reviewed and problems in marine biofilter acclimation appear to justify the development of new acclimations procedures.

Design and operation of nitrifying trickling filters in recirculating aquaculture: A review
TL;DR: In this article, the main mechanisms and parameters affecting the design and performance of trickling filters in aquaculture are discussed, including the relationship between nitrification rates and easily accessible process parameters, like bulk phase concentration of TAN, O2, organic matter (COD), nitrite, temperature, HCO3−, pH and hydraulic loading of the trickling filter.
Journal ArticleDOI
Electrochemical removal of nitrite and ammonia for aquaculture
TL;DR: In this paper, the authors investigated operating variables of the electrochemical method including the current input, pH, conductivity, buffer solution and initial nitrite and ammonia concentrations were considered to determine their respective effect on the efficiency of the removal of Nitrite and Ammonia.

Wastewater Engineering Treatment Disposal Reuse
TL;DR: Wastewater Engineering: An Overview of Wastewater Engineering, Methods and Implementation Considerations as mentioned in this paper is a good starting point for a discussion of the issues of wastewater engineering. But, it is not a complete survey of the entire literature.
Journal Article
A model of substrate utilization by bacterial films.
TL;DR: Mixing in natural environments, such as lakes, ponds, soils, seawater, and sediments, is rarely adequate to maintain complete bacterial growth, however; as a result, bacterial growth generally occurs on available sur faces.

Intensified fish culture combining water reconditioning with pollution abatement
Paul B. Liao,Ronald D. Mayo +1 more
TL;DR: It was found that a properly designed water reconditioning-reuse system, under conditions set forth, can provide necessary pollution abatement and increase a hatchery's fish carrying capacity tenfold as compared to a single-pass system.
Journal ArticleDOI
Growth and production of the African catfish, Clarias lazera (C. & V.). III. Bioenergetic relations of the body weight and feeding level
TL;DR: It was found that changes in proximate body composition that occurred at different feeding levels were largely attributable to concurrent changes in weight, which largely explains C. lazera's efficient utilization of the feed for growth.

TL;DR: Rhythms in egg production, artificial spawning, the role of pheromones, induction of triploidy, nutrition, feeding and growth of larvae and fingerlings, as well as health control are treated.
