I got £400 for a week once c 1985 for 3 rods & c 30 salmon. That‘s c £20 per rod day. I got £300 once for 2 Rods for one week when one rod got no fish and the other got 26 because he listened. Plus £20 when I got an 18- pounder out of weed by smacking the surface with an oar.
Might depend if its 1:1 or split, on 1:1 on a good beat not less than £30 per day, possibly similar to a days shooting on a driving day already suggested, also it might depend on if you will be going again to the same water and if your ghilly gave you a good day, doesn’t have to be productive. It would also depend on whether he’s payEd by the estate as well Or he’s totally self employed. If your one of 6 rods with a shared ghilly and he’s payed by the estate £10-£20 for the day.
