Fish Select dialog box
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. For various
reasons, the fish sizes presented in the
Size Distribution information pane may be inaccurate.
The
Fish Select
dialog box allows you to select the fish species you expect to catch. You can
then manually adjust the size distribution.
How to open
You open this dialog box from the
Setup
menu.
Description
If the information in the Size Distribution
information pane appears to be inaccurate, or the
information does not correspond with the actual
catch, the values can be modified.
Select the specie you are catching or looking for.
Tip
Once you are able to assess your catch, you can
use the
Fish Size Adjustment
page to change the average size of the various species. The
page is opened in the
Information Pane Options
dialog box. The
Information Pane Options
dialog box is only available when an Inspection view is active.

Environmental parameters such as salinity, and sound speed play an important part to present
accurate echo data. Use the
Environment
parameters to define these values. Depending on
the current sea and weather conditions, you may need to change these values frequently.
