For the extent of the southward copepodid distribution from the Orkney farms it is observed that the lice are channelled southwards from the Pentland Firth to occupy a large portion of the North Sea towards the Moray Firth. [...] The risk of infestation by salmon lice varies according to the density of lice to which the fish are exposed and the duration of that exposure [Johnsen_2020], [ScotGov_2024], [SEPA_2024]. [...] The level of agreement between the models is likely due to particles being restricted to the upper 10 m of the water column and salinity avoidance being less critical in the well-mixed open seas around the Northern Isles compared with stratified fjordic systems such as those found on the West Coast of Scotland. [...] In terms of lice distribution, it is evident that the lice are channelled southwards from the Pentland Firth to occupy a large portion of the North Sea towards the Moray Firth.
