Simrad SN90 Reference Manual
Horizontal Axis
The echo presentations in the Inspection views resemble the echograms you
see on an echo sounder. The echoes travel from right towards left across the
echogram presentation. Use the
scale of the echogram. This controls the "speed" of the echoes.
Information Pane Options
The SN90 system offers several information panes to provide additional and
detailed data from the presentations. The information panes are opened and closed
from the top bar. Several of the information panes are fitted with a
Select to open the
Active
dialog box to change the operating parameters for the data provided
Pane Options
in the information panes. This dialog box contains a number of pages selected
from the menu on the left side.
The following pages are provided:
Size Distribution
The Size Distribution information pane presents a histogram with the echoes
from single fish. The calculations are based on the fact that different fish
species have different echo strength. The echo strength also depends on the
operating frequency you use. Use the
properties for the histogram shown in the Size Distribution information pane.
Fish Position
The Fish Position information pane shows the position of the detected single
fish echoes. The information pane is only available when an Inspection view
is "active". Use the
for the Fish Position information pane.
Fish Size Adjustment
The Size Distribution information pane presents a histogram with the echoes
from single fish. For various reasons, the fish sizes presented in the Size
Distribution information pane may be inaccurate. Once you are able to
assess your catch, you can use the
average size of the various species.
School Mass Adjustment
When you have defined a priority target, the information in the Horizontal
view includes an estimate of its area and volume. Once you are able to
assess your catch, you can use the
the weight/volume proportions. This will increase the accuracy of the
information in the view.
