Question: Which trout stocked for the troughtmasters tournament is a species of salmonid? 
Context: Summit Lake Creek is a tributary of Leggetts Creek in Lackawanna County, Pennsylvania, in the United States.  It is approximately 2.1 mi long and flows through Newton Township and South Abington Township.  The watershed of the creek has an area of 3.08 sqmi .  It is a Trout Stocked Fishery and a Migratory Fishery.  Reaches of the creek are considered to be impaired.  There are a number of lakes and reservoirs in the watershed.  The creek has one unnamed tributary, which is known as Unt 28530. The brown trout ("Salmo trutta") is a European species of salmonid fish that has been widely introduced into suitable environments globally.  It includes both purely freshwater populations, referred to as the riverine ecotype or "Salmo trutta" morpha "fario" and a lacustrine ecotype, "S. trutta" morpha "lacustris", also called the lake trout,as well as anadromous forms known as the sea trout, "S. trutta" morpha "trutta".  The latter migrates to the oceans for much of its life and returns to fresh water only to spawn.  Sea trout in the UK and Ireland have many regional names, including sewin (Wales), finnock (Scotland), peal (West Country), mort (North West England), and white trout (Ireland). Since the recession of the last glaciation, isolated bodies of water high in mountain crevasses have been topographically separated from fish.  Within Washington state a number of lakes in the Olympic and Cascade Mountains have been stocked since the early 20th century.  Prior to the existence of a state wildlife management agency, the U.S. Forest Service stocked mountain lakes with rainbow trout (Oncorhynchus mykiss), cutthroat trout (Oncohynchus clarki) and eastern brook trout (Salvelinus fontinalis).  High lake management of this era largely focused on improving sport fishing opportunities and secondarily establishing ecological balance.  Natural reproduction of fish species, especially eastern brook trout, has led to overpopulation and “stunting” from starvation in low nutrient environments.  The result has been decreased interest from fishermen, while causing large, negative impacts on natural lake biota.  Addressing concerns for biodiversity can positively impact agendas for the conservation of species, as well as high lakes fishery management. Dr. Robert J. Behnke (December 30, 1929 – September 13, 2013) was an American fisheries biologist and conservationist who was recognized as a world authority on the classification of salmonid fishes.  He was popularly known as "Dr. Trout" or "The Trout Doctor".  His seminal work, "Trout and Salmon of North America", was published in 2002.  He wrote a regular column for "Trout Magazine", the quarterly publication of Trout Unlimited.  He was a fisheries biologist with the U.S. Fish and Wildlife Service in the Colorado Cooperative Fish and Wildlife Research Unit and a professor at Colorado State University in the 1970s.  He became a Professor Emeritus at the Department of Fishery and Wildlife Biology at Colorado State University. Church Pond is located south of Stark.  Church Pond is the source of the North Branch Grass River.  Fish species present in the lake are brook trout and black bullhead.  There are 350 to 400 brook trout stocked per year.  Access via state trail off state route 56 on the north shore. Middle Creek is a tributary of Schwaben Creek in Northumberland County, Pennsylvania, in the United States.  It is approximately 3.5 mi long and flows through Washington Township.  The watershed of the creek has an area of 3.28 sqmi .  The creek is designated as an impaired waterbody, with the cause of the impairment being siltation, low dissolved oxygen levels/organic enrichment, and vegetation removal and the source being agricultural activity.  The creek is classified as a Trout Stocked Fishery. The rainbow trout ("Oncorhynchus mykiss") is a trout and species of salmonid native to cold-water tributaries of the Pacific Ocean in Asia and North America.  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 fresh water to spawn after living two to three years in the ocean.  Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead. Troutmasters is the name of an annual fishing tournament taking place in the Wilson's Creek district of Pisgah National Forest in Western North Carolina.  The invitation only tournament takes place on the opening day of trout fishing season, normally the first Saturday in April, but has since been moved to June due to extreme weather conditions in early April (snow, wind, lava, etc).  Entrants begin fishing Friday morning through Saturday evening.  Wilson's creek is stocked by the North Carolina Fish Hatcheries division of N.C Game and Wildlife Commission.  The river is stocked with Rainbow, Brook, and Brown trout. The Gila trout ("Oncorhynchus gilae") is a species of salmonid, related to the rainbow, native to the Southwest United States.  Prior to 2006 the Gila trout was federally listed as endangered.  In July 2006, after much work by the Game and Fish departments in New Mexico and Arizona, the US Forest Service and the US Fish and Wildlife Service, the Gila trout was down-listed to threatened, with a special provision called a "4d rule" that will allow limited sport fishing – for the first time in nearly half a century.  This possibility is distinct: there may be no one alive today that has legally angled a pure Gila trout from its native waters.  By the time the Gila trout was closed to fishing in the 1950s, its numbers and range were so depleted and so reduced this copper-colored trout simply wasn’t very accessible to anglers.  As of 2011 there is fishing in both states for this beautiful fish. Spring Creek is a tributary of White Deer Hole Creek in Lycoming County and Union County, in Pennsylvania, in the United States.  It is approximately 8.2 mi long and flows through Washington Township in Lycoming County and Gregg Township in Union County.  The watershed of the creek has an area of 21.1 sqmi .  The creek is not designated as an impaired waterbody.  The area in its vicinity was settled by 1787 and a mill was constructed on it in 1842.  A number of bridges have been constructed over the creek.  Its drainage basin is designated as a Trout Stocked Fishery and a Migratory Fishery.
Answer: rainbow trout ("Oncorhynchus mykiss") is a trout and species of salmonid
