Description
Each coloured circle in the
information pane identifies a
single fish. You can observe how
these move through the beam. The
colours used are the same as the
colours used in the colour scale,
and these indicate the echo strength
from each fish. This information
pane can be useful during trawling.
Keep an eye on the
Fish Position
information pane to make sure
that you can manoeuvre the trawl
through the areas with most fish.
Several specific parameters are
available for studies of single
fish. In order to detect single fish correctly, these parameters should be defined to suit
the specie characteristics.
