Aker BioMarine developed and patented a continuous mid-water/pelagic trawl system, called "Eco-Harvesting" 2003.  

This technology, uses a specially designed trawl system and direct hose connection between the trawl and the vessel,  and holds a special mechanism that singles out unwanted by-catch (non-krill species) and releases it unharmed.  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..


"It’s a unique fishery that is a long way away. We also appreciate that, as such, it’s a fishery that brings some misgivings, which is why we want to be as transparent as we can. We are confident about our operations and want to put people at ease about them," Sigve Nordrum, Aker BioMarine sustainability director.
