TL;DR: This review aims to summarize the most recent developments within RAS that have contributed to the environmental sustainability of the European aquaculture sector and identifies the key research priorities that will contribute to the future reduction of the ecological impact of RAS.

TL;DR: It is suggested that steering of gut microbial communities could be possible through water microbial management derived by the design and functionality of the rearing system.

TL;DR: It isclude that periphyton can increase theproductivity and efficiency of aquaculturesystems, but more research is needed foroptimization.

TL;DR: Control of C/N ratio by the addition of a carbohydrate source to the pond water column benefited the extensive shrimp culture practices in three ways: increased heterotrophic bacterial growth supplying bacterial protein to augment the shrimp production, reduced demand for supplemental feed protein and subsequent reduction in feed cost and reduced toxic inorganic nitrogen levels in the pond as well as effluents.

TL;DR: This 75% higher production concurred with a lower inorganic nitrogen content in the water column, a higher THB abundance supplying additional single cell protein to augment the prawn production, and an improved periphyton productivity and quality.
