1. don't know

2. last time I tried they were all over the place, fishing the backwater area using corn, #10 hook on a feeder setup worked for me (Warning : big carp like small baits too). 

3. Caught a uni perch at Germany fishing the on the main peg, #1 or 1/0 hook, using small minnows also on a feeder setup, cloudy day fishing during peak (around 11am).

Hope this helps.

Thanks for the info carpman it's much appreciated, the one thing I haven't tried is a feeder so I will give it a go and hopefully catch the illusive fish . Cheers

Smashed the unique perch you're a legend mate thanks for the info was very much appreciated.  I'm still trying for young common carp at the moment , just unsure where the backwater is ? .

The little pond area at spawn point ( Believe its at top of map on GPS tablet ) . You can also get them close to reeds by boat launch but not at the rate in pond area.
