Mahmoud,
Where I fish (Oman) we spend a lot of time and effort trying to avoid them!!
During the day any jig with a bit of flash, particulalrly if it's holographic and flutters on the drop, is in danger. The problem is at night I'm not sure whether you'd get the same effect, depends on the amount of light about but don't really know because they've never been a target fish (for me at least). Maybe try one of those cyalume sticks attached to the jig itself...and well away from your line!
In general, I find that my ability to attract big barracuda is directly proportional to the cost of the jig.
Regards,
Trevor
