Theft and sabotage - a hidden cause of ghost fishing

Ghost traps are a growing problem in the ocean, and while weather, currents and boat traffic are often blamed, theft is an underestimated factor. When unauthorized persons steal the catch or cut the ropes that keep the traps anchored, they can end up as ghost traps that continue to catch fish and shellfish unchecked.

Research shows that theft or sabotage accounts for 10-15% of all ghost pots. In many cases, thieves choose not to pull up the entire pot, but instead empty it of its catch and leave it behind. Without its original attachment, the pot can drift away or sink to the bottom – invisible and irretrievable. Without a dowel or other visible marking, it becomes difficult, if not impossible, to find again.

This creates a vicious cycle where lost fish continue to fish for a long time, damaging both the stock and the environment. In addition, fishermen lose valuable equipment, leading to financial losses and frustration.

To combat this problem, it is important to secure gear, use technology such as GPS tracking, and raise awareness about illegal theft of catches. Innovative solutions such as TrapSaver™ can help reduce losses by ensuring that containers can always be found – even if they are subjected to sabotage.

Combating ghost fishing is not just about natural forces – it also requires measures against man-made causes such as theft and vandalism.
