Ballast weight for a fishing line

A ballast weight for a fishing line, comprising a main body (1) destined to be connected, during use, to the fishing line, which main body (1) comprises a front portion (2) and a rear portion (3) on which, at a tail end of the main body (1), an eyelet (7) is provided to enable connection of the main body (1) to the fishing line, characterised in that the main body comprises a through-channel (10) provided with an inlet opening (11) and one and only one outlet opening (12) located on the external surface of the main body (1), said through-channel (10) being overall orientated in a parallel direction to a longitudinal axis (x) of the main body (1) and being provided with a progression and a breadth that are variable, said through-channel (10) being structured such that, during a flight stage of the ballast weight, (a) the fishing line is attached to the eyelet (7) and the fishing line does not pass through the through-channel (10) and (b) there is created through an entire length of the through-channel (10) an effective flow of air that facilitates the flight of the ballast weight, the morphological characteristics of the profile of the through-channel (10) being such that, during the flight stage of the ballast weight there is created, through the entire length of the through-channel (10), an effective flow of air, the main body being free from the presence of a fish hook.
