“…The development was focused on simplicity and effectiveness of production units and economic sustainability in the view of current and future requirements for environmental sustainability [3,26]. The RHS was developed as a simple facility without special structures or technologies, potentially enabling its use for large producers as well as smaller operations.…”

Research into the use of recirculating aquaculture systems (RAS) addresses the question of how to achieve profitable production while consistently recycling water and nutrients with minimal fresh water demand and waste production. The RAS facilities require an adequate supply of fingerlings, and a facility for fingerling production in conjunction with each RAS can prevent disease transfer and ensure quality and continuous production. The time, space, and financial investment can be eliminated by hatching (purchased disease free ova) and rearing of fingerlings every 2-3 months. The present study evaluated (water quality assessment, feed utilization, production cycle duration) a simple low cost recirculating hatchery for salmonids as a safe and continuous source of fingerlings for further rearing in RAS. The tested recirculating hatchery enabled low cost efficient production on a small scale (at least 5 production cycles per year, > 63 000 fingerlings per each cycle), low fresh water demand (0.05 l.sec -1 ) with maintaining good rearing conditions, and environmental and zoohygiene safety. Such simple facilities can support the sustainability of inland aquaculture and strengthen the effort to deliver quality products with minimal operational and environmental costs.

“…The importance of adequate nutrition is a factor predicting future preferred diet composition, and the role of fish is likely to increase in human diets [2][3][4]. The ongoing over-exploitation of natural fish resources has led to expanded development of marine and freshwater aquaculture in recent decades [1,4,5].…”

“…RASs improve conditions for cultured fish by having greater control over environmental and water quality parameters and enhancement of feeding efficiency. Subsequently, RASs can allow for higher stocking densities than most aquacultural systems [91,100,[104][105][106][107][108][109][110] by sterilizing the water prior to (re)entry to the fish tanks, pathogens and contaminants are removed, reducing the risk of disease outbreaks and contaminant uptake by the fish [18,104,111]. Due to the on-land and recirculatory nature of RASs, the potential for fish escapes is greatly reduced [2,104].…”

“…This can be achieved through commercial-scale research to try and identify the best combination of devices on a site-specific basis; (2) the development of a specialized RAS platform for the sharing of knowledge amongst the relevant personnel [88]. If recirculated water is not properly sterilized, the reuse of water in RASs can lead to contaminants from feed and system components and diseases/pathogens accumulating in the system [18,104,111]. However, two studies by Tal et al (2009) and Martins et al (2011) found that contaminants in RASs were either below harmful levels or undetectable [90,100].…”

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.
