Abstract: A fishing line spool with different sizes of female threads for removably attaching to a threaded neck of a plastic bottle to create a jug line used for jug fishing. The spool is removed from the bottle for storage. The spool is provided with a line spool area around which fishing line is wrapped to store the line and with a double walled protection flange provided with penetrable material to receive the pointed end of hooks when the fishing line is not in use. A locking pin removably extends through pin openings provided on either side of the spool area to prevent fishing line from unwinding from the thread spool area and as a means of fixing the depth of the fishing line. The locking pin can be removed from the pin openings to allow the fishing line to be wrapped onto or unwrapped from the spool area.
