5.10 Effects of the vessel’s speed
The presentation of fish on the CAXX depends directly on the ves-
sel’s speed, as well as on the depth of the fish. When the vessel is
at rest, the echo traces will appear stretched and flattened. As the
vessel’s speed becomes greater, the echo traces will become shorter
and more arched. The reason for this change in appearance is that as
the vessel speed increases, fewer number of sound ‘pings’ strike each
fish. A low vessel speed will provide the most accurate information
of where fish are loacted.
