What are the rules on using floating bait hooks?

I've heard of fishing by using a water bottle or something else that floats with fishing line and a baited hook on it and just setting it in the water as a floating rig. What are the rules concerning the use of a floating device with a baited hook connected to it for fishing? How many can I use at a time?
Answer: 
What you describe is commonly known as a "bobber."  You can attach as many bobbers/bottles as you want to your line.  You can have two lines out at once with a Two-pole permit.  Without a Two-pole permit, you can only fish with one line.
