Protect your catch from killer whales
The fisherman’s problem
Longliners worldwide face catch predation by marine mammals. During the hauling of the longlines, opportunistic orcas visit fishing vessels to snatch fish from the lines as they are retrieved. These intelligent predators are a serious threat to the longlining industry worldwide. Orcas can substantially reduce the amount of fish like Patagonian toothfish, halibut or black cod landed per fishing trip, causing a great financial loss to the fishing operation. With no available products to deter the orcas in the past, captains could do little to avoid this predation then to steam for several days, away from the orcas or accept the loss of most of the catch.
The orcas’ problem
The longlining industry unintentially provides the orcas with an abundant and year round available food source. Becoming dependent on this food source is never beneficial to any predator. Their natural behavior will be reduced and delicate relations in the food web could be pushed out of balance.
The solution: Orca Saver
In cooperation with Mustad Autoline, SaveWave has addressed this problem and developed the Orca Saver.
The Orca Saver emits specially developed and extensively tested acoustic signals made to repel orcas from fishing vessels. Several fishermen and researchers are very enthusiastic about the Orca Saver and recommend the Orca Saver after seeing the economic benefits using this whale friendly solution.
Workings of the Orca Saver
Orcas, like other dolphins, use sonar for hunting and orientation. This highly developed and extremely sensitive system uses ultrasonic frequencies to help the orca locate prey. The Orca Saver exploits this sixth sense by emitting high energy sound waves and signals designed to deter the orcas from the hauling area around the fishing vessel. Years of testing resulted in the ultimate mix of frequency and signal patterns designed to maximize deterrence effect.
Prior to line-hauling, the Orca Saver has to be deployed using a crane. Optimal effect is achieved by lowering the Orca Saver to ten meters under water. The device is designed to be activated during hauling when orcas appear near the vessel.
The use of cutting edge and innovative techniques has made the Orca Saver an easy to use, affordable, sustainable and environmentally friendly product.
