Abstract

PURPOSE:To make possible displaying of fish net positions and their shapes simultaneously with fish group video and achieve higher operating characteristic by performing coupling of a plurality of net depth meters and sonar in a round haul net fishing method. CONSTITUTION:The response signal received in a vibrator 1 is received and amplified in a sonar apparatus 6 and is led to a code discrimination circuit 7, by which the corresponding net depth meter is decided. Next, the distance and depth of each depth meter are calculated in a distance-depth calculating circuit 8 and are led to a coordinate conversion circuit 9, by which the respective distances converted onto horizontal plane are obtained. In a mark generating circuit 10, the marks for displaying the positions of the respective depth meters on a CRT are generated and are supplied to a video circuit 11. On the other hand, the video signal of fish groups and the bearing of each depth meter on the horizontal plane are supplied from the sonar apparatus 6 and radar apparatus 13 to the circuit 11. The output of the circuit 11 is displyed as the net shape of the lower part of the fish nets and fish group video by a display device 12.
