The fishery of Antarctic krill is on the order of 100,000&nbsp;tonnes per year. The major catching nations are [[South Korea]], [[Norway]], [[Japan]] and [[Poland]].<ref>[http://www.ccamlr.org/pu/e/e_pubs/sb/sb-vol20.pdf CCAMLR Statistical Bulletin vol. 20 (1998-2007)] {{webarchive |url=https://web.archive.org/web/20090225124314/http://www.ccamlr.org/pu/e/e_pubs/sb/sb-vol20.pdf |date=February 25, 2009 }}, CCAMLR, Hobart, Australia, 2008.

First, a krill net needs to have very fine meshes, producing a very high [[Drag (physics)|drag]], which generates a [[bow wave]] that deflects the krill to the sides. Second, fine meshes tend to clog very fast.

Yet another problem is bringing the krill catch on board. When the full net is hauled out of the water, the organisms compress each other, resulting in great loss of the krill's liquids. Experiments have been carried out to pump krill, while still in water, through a large tube on board. Special krill nets also are currently under development. The processing of the krill must be very rapid since the catch deteriorates within several hours. Its high protein and vitamin content makes krill quite suitable for both direct human consumption and the animal-feed industry.<ref name="E+00">{{Cite book |author1=Inigo Everson |author2=David J.
