Fishing line information learning system

A fishing line information learning system, comprising:

• a fishing reel having a first communication unit and a spool including a pair of flange portions and a bobbin trunk, the bobbin trunk configured to have fishing line wound therearound between the pair of flange portions;
• and
• an electronic device having a camera configured to be capable of photographing the spool, a second communication unit configured to communicate with the first communication unit, and a first memory configured to store first information acquired by the camera,
• the fishing reel or the electronic device having
• a second memory configured to store a calculation formula to calculate a line winding amount of the fishing line in a range from a first time point when the winding of the fishing line is started to a second time point when the winding of the fishing line is ended, and
• a controller configured to estimate a final line winding diameter at the second time point based on the first information at the second time point, and calculate the line winding amount based on the final line winding diameter and the calculation formula.
