Simrad FX80 Catch monitoring system

System description

A real-time video feed from the trawl has long been desired by fishermen and researchers alike.

Cabling 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.

The Simrad 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.

A typical Simrad FX80 will provide:

  1. Title bar with navigational information and key functionality
  2. Live video feed
  3. Menu system for system control
  4. Status bar with operational information
