Technology offer : Dispositive to fight against depredation of catches by sharks and toothed whales for longline fishing

Technology's description


DEPRED is a dispositive designed to protect longline fishing catches against depredation caused by sharks and toothed whales ( dolphin, orca...), thanks to a visual and auditive lure.

Different types of lures can be  used, such as a protection ring, an acoustic reflection target, among others.


  • Decrease of fish losses
  • Reduction of fishing gears damages
  • Other acoustic dispositives to prevent depredation are inefficient for long term use
  • Positive effects for eco-system: decrease of fishing pressure, better fishing statistics, preservation of toothed whales
