Reduced environmental impact of antibacterial agents applied in fish farms using the LiftUp feed system or a hydroacoustic feed detector
(Journal article; Peer reviewed, 1994-07-28)High-performance liquid chromatography was used to quantify residues of oxolinic acid and flumequine in muscle of wild fish caught in the vicinity of fish farms using the LiftUp feed collector system or a hydroacoustic ... -
Residues of oxolinic acid in wild fauna following medication in fish farms
(Journal article; Peer reviewed, 1992-02-17)Dispersion of oxolinic acid and occurrence of Aeromonas salmonicida in wild fauna were studied in animals captured in the vicinity of 2 aquaculture facilities during and after medication with this drug. Consumption of ... -
Screening and characterisation of potentially pathogenic bacteria associated with Atlantic cod Gadus morhua larvae: bath challenge trials using a multidish system
(Peer reviewed; Journal article, 2008-09-24)In intensive aquaculture systems, high concentrations of nutrients and high densities of fish larvae provide favorable conditions for opportunistic pathogenic bacteria to flourish. We screened potentially pathogenic ... -
