Yeah, there are fish to be caught in the bubble. I've been out twice and put two in the boat, lost one. I don't think there are any secrets on what to use, I've seen fish caught on all of the normal stuff. One thing I make sure of is to keep the jellyfish stuff cleaned off of your gear. That means bringing it up every 5-10 minutes to clean it with a rag. I know it is a pain but you won't get bit dragging around jelly goo on your gear.
