“…Due to the on-land and recirculatory nature of RAS, the potential for fish escapes is extremely low and 90%-99% of water is recycled. They can be located on land unsuitable for other food production methods, in urban areas or close to markets Contaminants, parasites, and diseases can be removed or treated effectively through sterilization of the reused water and all wastes can be concentrated and treated or used as an input to other production systems (e.g., agricultural fertilizer or methane generation) [2,88,89,[100][101][102][103][104]. RASs can also be located away from water bodies, further reducing the potential for fish escapes to the environment, and allowing for the culture of faster-growing fish that have been selectively bred or genetically modified without the worry of potential biological invasion [2].…”

“…They improve opportunities for waste management, nutrient recycling, and biological pollution control. The majority of excess nutrients and waste material (uneaten feed, feces, dead bacteria) are removed before water is released to the environment, subsequently, RASs reduce potential negative impacts on marine and saline environments and ecosystems [2,88,89]. RASs improve conditions for cultured fish by having greater control over environmental and water quality parameters and enhancement of feeding efficiency.…”

“…One effective solution is the rearing of fish in recirculating aquaculture systems (RASs); defined in a paper by Zhang et al (2011) as "land-based aquatic systems where the water is (partially) re-used after mechanical and biological treatment in an attempt to reduce the consumption of water and energy and the release of nutrients into the environment" [89,90]. In general, with RASs, large solid particles of uneaten feed, feces, and bacteria are concentrated and removed by settling or mechanical filtration and fine particles (<100 microns) are removed by ozone treatment and/or foam fractionation [2,91].…”

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.

“…This suggests the necessity of developing production systems requiring fewer resources in order to reduce the ecological costs of human food production by (a) improved use of resources and (b) minimizing waste production and water pollution. To the latter end, alternative recirculating aquaculture systems have already been developed by the aquaculture industry in continental waters, for example those involving the construction of artificial freshwater wetlands using macrophytes (Culley et al, 1981;Corpron and Armstrong, 1983;Schwartz and Boyd 1995;Lin et al, 2003;Schulz et al, 2003;Li et al, 2007;Zachritz et al, 2008;Martins et al, 2010;Zhang et al, 2011). Wetlands as recirculation filters have also been developed for large-scale shrimp aquaculture in brackish water (Tilley et al, 2002), and for sea-water fish production (Hussenot et al, 1998;Brown et al, 1999).…”

A prototype of an integrated closed system for fish-plankton aquaculture was developed in Iquitos (Peruvian Amazonia) in order to cultivate the Tiger Catfish, Pseudoplatystoma punctifer (Castelnau, 1855). This freshwater recirculating system consisted of two linked sewage tanks with an intensive rearing unit (a cage) for P. punctifer placed in the first, and with a fish-plankton trophic chain replacing the filters commonly used in clear water closed systems. Detritivorous and zooplanktivorous fishes (Loricariidae and Cichlidae), maintained without external feeding in the sewage volume, mineralized organic matter and permitted the stabilization of the phytoplankton biomass. Water exchange and organic waste discharge were not necessary. In this paper we describe the processes undertaken to equilibrate this ecosystem: first the elimination of an un-adapted spiny alga, Golenkinia sp., whose proliferation was favored by the presence of a small rotifer, Trichocerca sp., and second the control of this rotifer proliferation via the introduction of two cichlid species, Acaronia nassa Heckel, 1840 and Satanoperca jurupari Heckel, 1840, in the sewage part. This favored some development of the green algae Nannochloris sp. and Chlorella sp. At that time we took the opportunity to begin a 3-month rearing test of P. punctifer. The mean specific growth rate and feed conversion ratio (FCR) of P. punctifer were 1.43 and 1.27, respectively, and the global FCR, including fish in the sewage part, was 1.08. This system has proven to be suitable for growing P. punctifer juveniles out to adult, and provides several practical advantages compared with traditional recirculating clear water systems, which use a combination of mechanical and biological filters and require periodic waste removal, leading to water and organic matter losses.

As the world's fastest ongrowing sector in food production, aquaculture has remarkable priority and needs technological improvements and new candidate fish species to overcome some limitation factors. Considering these issues, this study based on determining the flesh quality in terms of nutrient and mineral element composition of two potential fish species, common dentex (Dentex dentex) and greater amberjack (Seriola dumerili), in recirculation aquaculture system (RAS). On the nutrient basis, the dry matter content of 28.82% and fillet yield with a value of 53.28% of Dentex dentex were found significantly higher than (P<0.05) Seriola dumerili. Crude protein and lipid values demonstrated slight but insignificant differences between the species. Among the macro elements of K and Mg and micro elements of Cr, Mn and Ni were noticeably higher in common dentex than greater amberjack, but Zn level was present almost double amount in amberjack (P<0.05).
