Fish recognition
The echo strengths shown on the A-scope can
be useful in recognising the type of fish. Different
species of fish have different sizes and shapes
of swim bladders. The air in the swim bladder
reflects the ultrasonic pulse, so the strength of
the echo varies between fish species according to
the size and shape of the swim bladder.
When fishing among a school of fish and
catching them, note the fish species and the
strength of the echo that it returns on the
A-scope. Then, when that particular echo is seen
at future times on the fishfinder, it is likely to be
the same fish species.
5-6 A-Scope perspective view
The strength of echoes on this view are
determined by the ’height’ of the echo shown on
the screen.
