To ask the Scottish Executive what monitoring of the number of cases of sea lice infestation in the wild and farmed salmon populations it is carrying out and whether the number of cases has increased. Wild fish populations are regularly monitored by Fisheries Trust biologists, in collaboration with Fisheries Research Services.On marine salmon sites, weekly sea lice counts are carried out routinely by farmers to determine the trigger levels for treatments.There is better control of sea lice where Area Management Agreements are in place, and sea lice burdens on both farmed and wild fish appear to be reduced in the first year of production following a synchronised fallow.
