“…The accumulation of solids in a system also favors the growth of heterotrophic bacteria, which will compete for space on biofilters with the autotrophic species that are required to metabolize fish wastes (see “Biological Filtration”). The three types of waste solids found in a recirculating aquaculture system are settleable, suspended, and fine or dissolved solids (Losordo et al 1999). Settleable solids are those that will drop out of the water column.…”

“…Another more advanced type of solids removal is the employment of expandable granular media filters (Losordo et al 1999). In this design, solids are removed by passing water through a bed of granular media, usually sand or plastic beads.…”

“…The most important of these dissolved gases for aquaculture are oxygen, which should be kept as close to saturation at possible (no lower than 4 mg/L), and carbon dioxide, which should be kept at levels less than 20 mg/L (Losordo et al 1999). The exchange of these and other gases in a system is achieved by moving the surface of the water into contact with the atmosphere through various means, most typically air diffusers or air stones, surface agitators, and pressurized or nonpressurized packed columns (Losordo et al 1998). When this occurs, oxygen is added to the water, and carbon dioxide is removed (off-gassed).…”

“…Ideally, the aerating equipment should be sited at the point in the system where dissolved oxygen levels are at their lowest and carbon dioxide levels are at their highest (Losordo et al 1998). In most zebrafish housing systems, this location is typically just prior to where recycled water enters the housing tanks (usually after ultraviolet sanitization).…”

The strategies for housing zebrafish used in biomedical research have evolved considerably over the past three decades. To keep pace with the rapid expansion and development of the zebrafish model system, the field has generally moved from keeping fish at the level of aquarium hobbyist to that of industrialized, recirculating aquaculture. Numerous commercial system vendors now offer increasingly sophisticated housing systems based on design principles that maximize the number of animals that can be housed in a given space footprint, and they are thus able to support large and diverse research programs. This review is designed to provide managers, lab animal veterinarians, investigators, and other parties responsible for care and use of these animals with a comprehensive overview of the basic operating and design principles of zebrafish housing systems. This information can be used to help plan the construction of new facilities and/or the upgrade and maintenance of existing operations.

The ability of a commercial‐scale Cyclobio fluidized sand filter was evaluated for ammonia and nitrite removal by dosing with ammonia chloride, NH4Cl, as part of the water treatment unit for the U.S. Department of Agriculture Agricultural Research Service Warmwater Aquaculture Research Unit's (WARU) catfish hatchery in Stoneville, Mississippi, USA. Treatment system water was recirculated through the Cyclobio filter for several months without any feed inputs; thus, our objective was to investigate how quickly a full‐scale Cyclobio fluidized sand filter could be reactivated with NH4Cl substrate dosing in preparation for the upcoming spawning season. A second objective of the study was to examine the decline of the filter's nitrification ability when the supplementary NH4Cl substrate dosings were removed or limited. The effects of daily and weekly substrate additions were evaluated over a 14‐week winter period, with the system water temperature ranging between 20° and 23°C. Total ammonia nitrogen (TAN) concentration decreased within hours of initial dosing. After approximately a 2‐h lag period, the nitrite–nitrogen concentration peaked and then decreased. The rate of TAN nitrification followed a simple first‐order reaction kinetics and increased over time during the 4 weeks of daily NH4Cl substrate dosing. The return to a weekly substrate dosage resulted in a decrease in the kinetic reaction rate, but adequate to maintain the filter during periods of system inactivity. The once‐daily substrate dosage was consumed within hours of the initial dosing and was sufficient for current system loading.
