Introduction
Marport's Catch Navigator tells you when your trawl starts to fill. Placed on the top of
the trawl codend, it monitors the amount of catch that you have and warns you when
the trawl is full. You can even use it to determine a precise amount of fish inside the
trawl net. This way, you can monitor the contents of the codend while you are fishing,
avoid problems of overfilling and increase fish survival rate inside the trawl net. It is
recommended to install several sensors along the trawl to better monitor the filling
processes.
The Catch Navigator provides a high-definition echogram image of the volume of catch
inside the codend. In order to efficiently follow the trawl descent, echogram ranges are
configurable from 5 to 160 meters. Moreover, the sensor includes an automatic range
mode: when descending, the sensor can automatically switch to a lower range of 20
meters to get sharper pictures. Optionally, it can also track pitch, roll, depth, height and
temperature data.
