Modelling sea lice dispersion under varying environmental forcing in a Scottish sea loch
Abstract The spread of infectious larval sea lice, Lepeophtheirus salmonis (Krøyer, 1838), between wild salmonids and farmed Atlantic salmon, Salmo salar , remains a contentious area of uncertainty. However, as laboratory and field experiments increase our knowledge of sea lice behaviour under envir...
