I don't believe that HQ bait exists. If I remember right getting CUL to 15, you could not HQ crayfish balls. I'm not in game atm to be able to confirm but anyone with CUL can tell you.
I believe Perception increases your chance of HQ gathers.

I have never hit an HQ crawfish ball (Cajun style people!) on my CUL...though I didn't really cook for very long.
And yes, PERCEPTION is the HQ factor in gathering. I use Jack O' Lanterns when I fish and it does help...along with gear upgrades. This also directly impacts mooch rates... and the dreaded double mooch rates.
