Aker BioMarine developed its patent pending Eco-Harvesting® technology based on its krill harvesting activity since 2003. This technology, using a specially designed trawl system and direct hose connection between the trawl and the vessel, holds a special mechanism that singles out unwanted by-catch (non-krill species) and releases it unharmed.
Harvesting krill in a commercially viable and environmentally sound way is challenging. Traditional trawling methods where the catch is hauled up on deck and emptied into holding tanks before processing is unsuitable, as the krill contains highly digestive enzymes and basically self-destructs before it can be processed.
Aker Eco-Harvesting® fishing system allows the fishing net to stay under water during the entire operation. Independent observers have verified that the proprietary technology and novel harvesting method ensures no by-catch of other species than Euphausia superba.
The equipment stays under water while a continuous stream of water flows through the hose, bringing the krill live and fresh directly into the factory vessel, which allows for processing of fresh raw material with superior product quality.
Eco-Harvesting® results in minimal environmental impact. The innovative, sustainable krill harvesting will allow future generations to reap bounteous harvests of krill for yet-to-be-developed uses of this tiny but nutrition-packed crustacean.
