caption_attribution_description: English: Antarctic krill Euphausia superba. This is the startimage of the virtual microscope http://www.ecoscope.com/cybermic/index.htm of krill where you can click into details of the animal to get higher magnifications, like the gills, the feeding basket or the swimming legs, up to raster electron and transmission electron images, also some videos - there are many links to jumpoff sites for educators, like from the SCIENCE MAGAZINE. http://www.ecoscope.com/science/index.htm In natural hovering position - the red organs produce the bioluminescence - the hepatopancreas is filled with green phytoplankton, the food of krill, the strait gut in the back is filled with the empty shells of phytoplankton - in the front you see the compound eye - the green dots in the water are the phytoplankton which krill filter with their thoracopods out of the water
context_page_description: A fishery is an area with an associated fish or aquatic population which is harvested for its commercial value. Fisheries can be marine or freshwater. They can also be wild or farmed.
  Wild fisheries are sometimes called capture fisheries. The aquatic life they support is not controlled in any meaningful way and needs to be "captured" or fished. Wild fisheries exist primarily in the oceans, and particularly around coasts and continental shelves. They also exist in lakes and rivers. Issues with wild fisheries are overfishing and pollution. Significant wild fisheries have collapsed or are in danger of collapsing, due to overfishing and pollution. Overall, production from the world's wild fisheries has levelled out, and may be starting to decline.
  As a contrast to wild fisheries, farmed fisheries can operate in sheltered coastal waters, in rivers, lakes and ponds, or in enclosed bodies of water such as tanks. Farmed fisheries are technological in nature, and revolve around developments in aquaculture. Farmed fisheries are expanding, and Chinese aquaculture in particular is making many advances.
