Is habituation measurable in lumpfish cyclopterus lumpus when used as cleaner fish in Atlantic salmon Salmo salar aquaculture?
To investigate how lumpfish interact in Atlantic salmon aquaculture, physiological stress responses and changes in behaviour were analysed in experienced and naive lumpfish. Experienced lumpfish (30.2 ± 7.93 g, mean ± SD) coexisted with a commercial scale production unit of Atlantic salmon (1258.5 ±...
