  • Description: 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 super( -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.
