Figure 6 - Catch data page for trawling

In order to get the school presentation and the school data, the

automatic target tracking must be used. The vertical distribution

of the school is determined by manual or automatic tilting of the

sonar beam. Note that the school on the catchdata page can be out

of centre because it depends on the position of the target’s centre

of gravity. The trawl symbol should always be sighted on the

horizontal centre of this page.

When the trawl symbol is selected, and the extension of the

trawl’s course is inside a distance of 200 meters from the target,

the trawl symbol should be visible on the catch data page.
