“…O 3 has multiple functions such as decomposing dissolved organic matter (DOM) and controlling algae, color, odor and taste, 5 and thus is mainly used to improve the physicochemical aspects of water quality rather than disinfection. 6,7 Because O 3 cannot provide a persistent residue in water distribution systems, a secondary disinfectant (e.g., Cl 2 , NH 2 Cl, or ClO 2 ) is required to maintain continuous disinfection ability.…”

Disinfection is commonly employed in recirculating mariculture systems (RMS) to control animal diseases and improve seawater quality; however, little is known about the occurrence of disinfection byproducts (DBPs) formed in such RMS. Beijing Aquarium is a typical RMS with artificially prepared seawater and mainly adopts a decentralized treatment strategy for different animal tanks, including sand filtration, foam fractionation, and disinfection (O 3 , UV, and O 3 /ClO 2 ). This study reveals that the adopted disinfection processes were highly effective in controlling marine heterotrophic bacteria; however, some concerns were raised on the formation of various kinds of DBPs, including secondary oxidants, inorganic oxyanions, and hazardous organic species. Free chlorine and free bromine were generated from ozonation at health-relevant concentrations. High concentrations of Environmental impactRecirculating mariculture systems (RMS) have been widely employed in marine aquaria around the world. Hazardous disinfection byproducts (DBPs) formed during the seawater treatment of RMS has been neglected for a long time. This study investigated the formation of various kinds of DBPs (i.e., secondary oxidants, inorganic oxyanions, and hazardous organic species) in animal tanks of a typical RMS, which raised serious concerns on the health threats of the detected DBPs to aquarium animals. To solve these problems, potential control measures for DBPs are proposed. This study provides useful and timely information to the mariculture industry regarding the occurrence and control of DBPs.

“…Ozone can then be supplied to the water by the same techniques used for oxygenation ( Figure 13 and see Vilbergsson et al [2]). It needs to be taken into considerations that the equipment is made of ozone-resistant material and that it is leak free, due to the high oxidizing properties and toxicity of ozone [60]. In brackish and seawater systems, ozone reacts with bromide ions and is transformed into total residual oxidants (TRO).…”

This is the third part of the taxonomy of technical solutions and treatment functions in aquaculture. This article builds on the premiss that the aquaculture production system can be viewed as a transformation process with three sets of functions, input, treatment and output. This work creates an overview of all of the technical solutions of treatment functions for the purpose of both design and further research. This is done with a comprehensive literature review where all technical solutions are identified and then categorized into a taxonomy. The result is a visual taxonomy of the treatment functions controlling N compounds, organic matter, P compounds, metals, temperature and preventing disease. A total taxonomy is finally presented where the results from Part 2 and Part 3 (this part) have been combined.

“…Therefore, many operators will run air through the CO 2 rich wastewater to degas the CO 2 and increase the oxygen concentration [91]. Ozone gas and ultraviolet lamps are also often used to kill fungal, viral, bacterial, and protozoan pathogens in the water prior to its re-entry to the culture tanks or being discharged [98,99].…”

Abstract:The demand for seafood products on the global market is rising, particularly in Asia, as affluence and appreciation of the health benefits of seafood increase. This is coupled with a capture fishery that, at best, is set for stagnation and, at worst, significant collapse. Global aquaculture is the fastest growing sector of the food industry and currently accounts for approximately 45.6% of the world's fish consumption. However, the rapid development of extensive and semi-extensive systems, particularly intensive marine-fed aquaculture, has resulted in worldwide concern about the potential environmental, economic, and social impacts of such systems. In recent years, there has been a significant amount of research conducted on the development of sustainable saltwater-based food production systems through mechanical (e.g., recirculatory aquaculture (RAS) systems) methods and ecosystem-based approaches (e.g., integrated multi-trophic aquaculture (IMTA)). This review article will examine the potential negative impacts of monocultural saltwater aquaculture operations and review established (RAS) and novel (IMTA; constructed wetlands; saltwater aquaponics) saltwater-based food production systems and discuss their (potential) contribution to the development of sustainable and environmentally-friendly systems.
