Ferox trout, help please

[Nippur]

Hello. I've been trying to catch all big fishes to complete the silver award in Scotland. I'm just missing a few, Ruffe, Atlantic Salmon, Burbot and Ferox Trout.
I tried everything around the whole map, every hour.
Fly fishing, dry and wet flies. Float. Bottom. Spinning. Trolling. Thinner lines, Hooks 1, 2 and even 3. Got several trophies from other species, but can't get even a large Ferox trout, all greens. I still have to see a large.
Any help for this fish?

Ruffe- the dock to the Right from the spawn point, blood worms, 50% cast , it will take some time- I have 7 trophy's from that spot. Burbot- The dock to the left from the spawn point- use Roe or cray fish tails- 50% cast as well.- I am still missing the Ferox trophy myself.

Man, this fish is driving me nuts. 165 caught, none large yet. 3 real life days chasing this fish, I don't even want a trophy, I just want my silver award.

Local records aren't even trophies except the first. It's weird.

My biggest catch is 4.168kg, I need 4.840kg.

I finally could catch 6 large ferox trouts today. I will keep fishing trying to reach the weight for silver.

Here's a screenshot of the current records.

I caught the trout , finally, after more than 5 days farming. Now I will go for the others, Northern Pike, Atlantic Salmon and Ruffe.
