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: This study confirms the contribution of IEL (mainly T-like cells) and basophils in the enteritis process and shows a clear involvement of up- and down-regulated cytokine genes in both the onset and recovery of the SBM-induced enteritis in the hindgut of carp.

TL;DR: Analyzing nutrient conversions, which are taking place in integrated intensive aquaculture systems, finds that fish culture alone retains 20–50% feed nitrogen and 15–65% feed phosphorous and the combination of fish culture with phototrophic conversion increases nutrient retention of feed N and feed P by up to 53%.

TL;DR: In this article, the main mechanisms and parameters affecting the design and performance of trickling filters in aquaculture are discussed, including the relationship between nitrification rates and easily accessible process parameters, like bulk phase concentration of TAN, O2, organic matter (COD), nitrite, temperature, HCO3−, pH and hydraulic loading of the trickling filter.

TL;DR: It is found that eels swim 4–6 times more efficiently than non-eel-like fish, removing a central objection to Schmidt's theory by showing that their energy reserves are, in principle, sufficient for the migration.
