Fish Tagging

When you use the Fish Tagging mode, information about the

current geographical position received from the ship’s satellite

navigation system (GPS) are coded and transmitted on the sonar

signal. The fishery research communities are placing tiny

electronic tags with a built-in GPS receiver on fish. When you

start this mode, fish with implanted tags within a radius of 5 km

from the ship will receive and store the information about the

geographical position, as well as depth and temperature. When

the fish is caught, the migratory route of the fish through a

whole year can be reconstructed.

Note that when the Fish Tagging mode is activated, the sonar is

used only for this purpose. Thus, no echoes will be shown on

the display.
