Number of fish calculation method, number of fish calculation device, number of fish measurement method, number of fish measurement system, number of fish calculation program
PROBLEM TO BE SOLVED: To provide a method for calculating the number of fish, which makes it possible to obtain the number of fish, which is the number of fish, from the information obtained in a state where the fish is made to swim in a cage. SOLUTION: A fish number calculation device 100 includes at least a recording unit and a fish number calculation unit. The recording unit records a value related to the amount of change in capacitance. The fish number calculation unit calculates the number of fish at the time of the fish number survey. The tail number measuring system 10 includes a set of measuring electrodes installed in the cage, a capacitance measuring device for measuring the capacitance between the measuring electrodes, a recording unit, a change amount calculation unit, and a tail number calculation unit. The number calculation device 100 is provided. The change amount calculation unit calculates a value related to the change amount of the capacitance and records it in the recording unit.
