Applications

Here are some examples of data received from Catch Explorer and Catch sensors displayed in Scala2.

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.

For example, you can install three sensors on the codend. They will trigger one by one, according to the amount of fish inside the codend. After a few tows, you can estimate the amount of tonnage of fish that you have depending on whether one, two or three sensors display a full status.

 5. Bottom disappears because fish block the signal

6. Codend is full

7. Alert that Catch is full

  1. High strength echogram level gets thicker with fish in the codend
  2. Catch pull cords trigger
  3. Pitch and roll begin to stabilize
