Fisheries Patrol is still done by Direct Flight: I believe Exeter based.
Highland Airways also do it from Inverness on C406 or 404 I think.
FR Aviation are based at Humberside / Teeside and fly the Falcon (they may well have other types too eg Kingair.
Scottish Air Ambulance also fly Kingair on "mercy" missions. They are a subsidiary of GAMA Aviation.
I do not fly with any of these operators but have friends who do (bar Direct Flight).
Try the Mil Aircrew Forum re FR Aviation.
Cheers
