The present invention relates to a fishing net management system which displays the location of a fishing net, an identifier, and the remaining fishing net battery time on an electronic navigation chart on a screen by receiving fishing net location information, identifier information, and remaining fishing net battery time information from a fishing net information transmission device installed on a fishing net via wireless communication. The present invention comprises a fishing net information transmission device (100) installed on a fishing net (110) so as to wirelessly transmit the fishing net (110) location information, the identifier information, and the remaining electricity information of a battery installed on the fishing net (110) via an antenna (103) and to allow a remote ship (180) to receive the transmission wirelessly. The ship (180) comprises: a fishing net information reception device (120) which receives the fishing net (110) location information, the identifier information, and the remaining electricity information of the battery installed on the fishing net (110) which are transmitted by the fishing net information transmission device (100) by using an antenna (122) an electronic navigation chart storage unit (135) which stores electronic navigation chart information and a fishing net management device (130) which displays the fishing net (110) location, the identifier, the ship (180) location, and the remaining electricity of the battery installed on the fishing net (110) on the electronic navigation chart based on the information received by the fishing net information reception device (120) and the electronic navigation chart information stored in the electronic navigation chart storage unit (135). According to the present invention, since the fishing net (110) location, the identifier, and the remaining fishing net battery time are received from the fishing net information transmission device (100) installed on the fishing net (110), and the f
