A real-time video feed from the
trawl has long been desired by fishermen and researchers alike.
and slip-rings have been the issue. One of the primary design criteria
of the Simrad FX80 system was to make it work on existing 3rd wire
cables. We have achieved this goal using copper core coax cables.
The use of existing copper core coax cables eases the cost and reduces
the installation time.
Real-time video is and will be of significant
use when addressing by-catch and by-catch avoidance issues. Trawl
behaviour can be viewed in real time with the FX80 system. Fish behaviour
can also be observed in real time. The real-time aspects and advantages
of the FX80 takes the speculation and guess work out of the equation.
This has the potential to increase the efficiency of any trawling
operation and will stimulate the creativity of fishermen, trawl and
gear manufacturers and of course, Simrad.
The Simrad DFS75 Trawl
sonar is integrated into the Simrad FX80 system to establish an efficient
and accurate monitoring system for your gear and your catch. The combination
of the high resolution images from the trawl sonar and the live video
feed provides you with an unparalleled opportunity to identify and
analyse both trawl movements and fish behaviour.
FX80 system is based on a well proven high resolution underwater camera
from Kongsberg Maritime. Accompanied by a high-density LED light,
the camera is usually placed under the headrope or in the cod end,
pointing with the desired angle. The camera sends its information
to the FX80 Communication Hub installed inside the FX80 Deployment
Unit, which is usually located near the headrope. The communication
between the hub and FX80 Bridge Control Unit is made by a standard
3rd wire cable.
The entire Simrad FX80 system – with live
video and high resolution sonar – is controlled from a standard
Processor Unit provided by Simrad. It is small, but yet powerful,
and contains no moving parts. The system design will allows you to
use two displays. Many users prefer this configuration, as it allows
them to use one display system for the trawl sonar presentations,
and another for the live video feed.
