  • Page 6: Introduction And Presentation

    There are two types of catch sensors: • Catch sensor: gives you the catch status of the trawl (empty or full), along with depth, water temperature and pitch and roll information. Catch sensors can emit on a single frequency of 40 kHz (Marport, Scanmar) or 70 kHz (Simrad, Wesmar), or on a dual frequency (40 kHz/70 kHz).

  • Page 7: Applications

    Catch Sensors | V1 | Introduction and Presentation Applications Here are some examples of data received from Catch Explorer and Catch sensors displayed in Scala. Catch Control System Installation You can install several sensors on the codend to better follow the filling processes. It is very useful to determine the amount of fish inside the trawl net: you can prevent damage to fish and increase the security of crew and vessel.
  • Page 8 Catch Sensors | V1 | Introduction and Presentation Catch Explorer display When the codend is full, you cannot see the sea bottom anymore because fish may block the signal.
