Selecting fish species and changing their size to improve the
size distribution information
The Size Distribution information pane shows a histogram of the echoes detected
from single fishes. The calculations are based on the fact that different fish species
have different echo strength. For various reasons, the fish size 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, and manually adjust the size distribution.
Context
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 fish type you are catching or looking for, then adjust the size.
