2022-3-1·Author summary In this paper we demonstrate that marine-fed farmed salmon is an inefficient way to produce nutritious seafood, and that directing wild-caught ‘feed’ fish towards human consumption could maximise nutrient production while also relieving pressure on fisheries stocks. Substantial growth in aquaculture is required to …

Microbial communities in recirculating aquaculture systems (RAS) play a role in system success, nutrient cycling, and water quality. Considering the increasing socio-economic role of fish farming, e.g., regarding food security, an in-depth understanding of aquaculture microbial communities is also relevant from a management perspective, especially …

2023-2-13·The effect of the rigor stage (pre or post) and previous high-pressure processing (HPP; 450 and 550 MPa for 3 min) was checked during the storage on ice of farmed palm ruff (Seriolella violacea). Fish processed in pre-rigor conditions led to higher and lower levels (p < 0.05) of moisture and lipid contents in chilled fish, respectively, …
