Rigs tips and bait for UK Sturgeon

[Wilza]

Hi! I'm after some tips on sturgeon fishing, I caught my first ever sturgeon the other day! a small one (about pound and a half) on a float fished prawn on limpenhoe lakes Norfolk. When i go again i'm thinking of ledgering a chunk of Mackeral hair rigged over large Halibut pellets!? Anyone got any tips? I'm trying to avoid lots of carp & tench in the lake! there is one strurgeon pushing 10lb so I've heard,i would like to catch it, Would night fishing for them be best!?
