Euphausia crystallorophias is a species of krill, sometimes called ice krill, [1] crystal krill, [2] or Antarctic coastal krill. [2] It lives in the coastal waters around Antarctica , further south than any other species of krill. [ 2 ]
Thysanoessa raschii, sometimes known as Arctic krill, is one of the most common euphausiid species of the subarctic and Arctic seas. They may reach 20–25 millimetres (0.8–1.0 in) long, and are sexually mature above 14 mm (0.6 in). [1] T. raschii is a major prey item of several taxa, planktivorous fishes and marine mammals.
Steelhead in 1924 illustration using the original taxonomic name, Salmo gairdneri The freshwater form of the steelhead is the rainbow trout (Oncorhynchus mykiss).The difference between these forms of the species is that steelhead migrate to the ocean and return to freshwater tributaries to spawn, whereas non-anadromous rainbow trout do not leave freshwater.
Krill also release faecal pellets (3) whilst they feed, which can sink to the deep sea but can be consumed (coprophagy) and degraded as they descend (4) by krill, bacteria and zooplankton. In the marginal ice zone, faecal pellet flux can reach greater depths (5). Krill also release moults, which sink and contribute to the carbon flux (6).
Krill is a rich source of protein and omega-3 fatty acids which are under development in the early 21st century as human food, dietary supplements as oil capsules, livestock food, and pet food. [10] [11] [12] Most krill is processed to produce fish food for use in aquariums and aquacultures. The krill is sold freeze-dried, either whole or ...
Antarctic krill (Euphausia superba) is a species of krill found in the Antarctic waters of the Southern Ocean. It is a small, swimming crustacean that lives in large schools, called swarms , sometimes reaching densities of 10,000–30,000 animals per cubic metre. [ 3 ]
The rainbow trout (Oncorhynchus mykiss) is a species of trout native to cold-water tributaries of the Pacific Ocean in North America and Asia. The steelhead (sometimes called steelhead trout) is an anadromous (sea-run) form of the coastal rainbow trout (O. m. irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to freshwater to spawn after living two to three years ...
Southern California Steelhead depend on rain fed streams for their survival, as well as lagoon/estuary type systems that is typical for some Southern Steelhead. [16] Spawning cycles are not fully understood, and many fish will not return to streams for over five years, while some will return after only one year in an attempt to successfully spawn.
