Abstract: A fishing float assembly for use with a fishing line, and having a chemiluminescent light stick assembled thereto, is provided. The fishing float is a standard fishing float, having an upstanding substantially rigid circular neck at its top, to which is assembled an attachment portion. The attachment portion comprises a body having a sleeve in its lower end, where the sleeve has one or a plurality of slits formed along its length, and has a collar fitted over the sleeve. Either or both of the sleeve and collar may have sloping faces such that downward movement of the collar along the sleeve causes the sleeve to constrict and thereby grip the neck portion of the float. At the upper end of the body of the attachment portion, a socket is formed and dimensioned so as to grippingly retain a chemiluminescent light stick when placed therein. The light sticks are, themselves, available in the market, and have standard and constant dimensions.
