Thereafter, the server 150 waits to perform the step (S115) of receiving new fishing net information to be transmitted in the next cycle.

When the fifth speed Vc5 exceeds the second reference speed Vref2 (YES in S155), the server 150 calculates the moving distance of the first fishing net 110-1 (S160).
