Assessment of microbial activity in water based on hydrogen peroxide decomposition rates
(Journal article; Peer reviewed, 2019)This study proposes a new and simple assay that allows rapid assessment of microbial activity in water samples. The assay consists of standardized hydrogen peroxide (H2O2) addition to a water sample and subsequent ... -
Changes in microbial water quality in RAS following altered feed loading
(Journal article; Peer reviewed, 2018)Intensive recirculating aquaculture systems (RAS) with its hyper-eutrophic water offer ideal conditions for bacterial growth, abundance and activity, potentially affecting fish and system performance. Feed composition and ... -
Coagulation of phosphorous and organic matter from marine, land-based recirculating aquaculture system effluents
(Peer reviewed; Journal article, 2021)Saline effluents from marine land-based aquaculture production can neither be disposed in common municipal wastewater treatment plants, nor disposed as landfill. Furthermore, stricter environmental regulations require the ... -
Hydrogen sulphide dynamics in recirculating aquaculture systems with moving or fixed bed biofilters: A case study in two commercial salmon smolt producing farms in Norway
(Peer reviewed; Journal article, 2024)Sudden mass mortalities of fish reared in recirculating aquaculture systems (RAS) have occurred in recent years. High total dissolved sulphide (H2S + HS- + S2-) levels in the rearing water have been suggested as an underlaying ... -
Microbial dynamics in RAS water: Effects of adding acetate as a biodegradable carbon-source
(Journal article; Peer reviewed, 2019)This study evaluated the effect of an abrupt increase in easily biodegradable carbon (acetate) on bacterial activity and abundance in the water of recirculating aquaculture systems (RAS). The study included a batch experiment ...
