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.
