Question: What did the O'Chiese First Nation trade in "Fur trade"?

Context paragraphs:
Siberian fur trade: The Siberian fur trade is an exchange concerned with the gathering, buying, and selling of valuable animal furs that originate from Siberia.  The Siberian fur trade expanded from localized trade and Siberian fur is now traded around the world.  The Siberian fur trade had a significant impact on the development of Siberia through exploration and colonization.  The fur trade also precipitated a decline in the number of fur-bearing animals and resulted in Siberia being conquered by Russia.

Iron Confederacy: The Iron Confederacy (or "Confederation", also called in Cree: "Nehiyaw-Pwat" or in English Cree-Assiniboine) was a political and military alliance of Plains Indians of what is now Western Canada and the northern United States.  This confederacy included various individual bands that allied together against common enemies.  The ethnic groups that made up the Confederacy were the branches of the Cree people that moved onto the Great Plains around 1740 (the southern half of this movement eventually became the "Plains Cree" and the northern half the "Woods Cree"), the Saulteaux (Plains Ojibwa), the Assiniboine, and the Assiniboine's Canadian descendants of today, the Nakoda, plus Iroquois and Métis involved in the fur trade.  The Confederacy rose to predominance on the northern Plains during the height of the North American fur trade when they operated as middlemen controlling the flow of European goods to other native nations, and the flow of furs to the Hudson's Bay Company (HBC) and North West Company (NWC) trading posts.  Its peoples later also played a major part in the bison (buffalo) hunt, and the pemmican trade.  The decline of the fur trade and the collapse of the bison herds sapped the power of the Confederacy after the 1860s, and it could no longer act as a barrier to U.S. and Canadian expansion.

Sunchild First Nation: The Sunchild First Nation is a Cree First Nation in Alberta, Canada part of Treaty 6, signed on May 25, 1944 under the leadership of Chief Louis Sunchild.  The First Nation has one reserve, Sunchild 202.  The reserve, 52.18 km2 in size, is located approximately 60 km northwest of Rocky Mountain House.  It shares the western border of the O'Chiese First Nation.

Yellowhead Tribal College: Yellowhead Tribal College is an educational institution located in Edmonton, Alberta, Canada which is run by four member nations of Treaty 6 with the four members being Alexander First Nation, O'Chiese First Nation, Sunchild First Nation and Alexis Nakota Sioux Nation.

O'Chiese 203: O'Chiese 203 is an Indian reserve in Alberta, Canada and is one of two reserves under the administration of the O'Chiese First Nation, a Saulteaux government.  It is located 119 km northwest of Red Deer.  It is at an elevation of 1007 m .  The reserve is bordered by Clearwater County to the west and east, Brazeau County to the north, and the Sunchild 202 Indian Reserve to the south.

Maritime fur trade: The maritime fur trade was a ship-based fur trade system that focused on acquiring furs of sea otters and other animals from the indigenous peoples of the Pacific Northwest Coast and natives of Alaska.  The furs were mostly sold in China in exchange for tea, silks, porcelain, and other Chinese goods, which were then sold in Europe and the United States.  The maritime fur trade was pioneered by Russians, working east from Kamchatka along the Aleutian Islands to the southern coast of Alaska.  British and Americans entered during the 1780s, focusing on what is now the coast of British Columbia.  The trade boomed around the beginning of the 19th century.  A long period of decline began in the 1810s.  As the sea otter population was depleted, the maritime fur trade diversified and transformed, tapping new markets and commodities, while continuing to focus on the Northwest Coast and China.  It lasted until the middle to late 19th century.  Russians controlled most of the coast of what is now Alaska during the entire era.  The coast south of Alaska endured fierce competition between, and among, British and American trading vessels.  The British were the first to operate in the southern sector, but were unable to compete against the Americans, who dominated from the 1790s to the 1830s.  The British Hudson's Bay Company entered the coast trade in the 1820s with the intention of driving the Americans away.  This was accomplished by about 1840.  In its late period, the maritime fur trade was largely conducted by the British Hudson's Bay Company and the Russian-American Company.

North American fur trade: The North American fur trade was the industry and activities related to the acquisition, trade, exchange, and sale of animal furs in North America.  Aboriginal peoples in Canada and Native Americans in the United States of different regions traded among themselves in the Pre-Columbian Era, but Europeans participated in the trade beginning from the time of their arrival in the New World and extended its reach to Europe.  The French started trading in the 16th century, the English established trading posts on Hudson Bay in present-day Canada in the 17th century, and the Dutch had trade by the same time in New Netherland.  The 19th-century North American fur trade, when the industry was at its peak of economic importance, involved the development of elaborate trade networks and companies.

American Fur Company: The American Fur Company (AFC) was founded in 1808, by John Jacob Astor, a German immigrant to the United States.  During the 18th century, furs had become a major commodity in Europe, and North America became a major supplier.  Several British companies, most notably the North West Company and the Hudson's Bay Company, were eventual competitors against Astor and capitalized on the lucrative trade in furs.  Astor capitalized on anti-British sentiments and his commercial strategies to become one of the first trusts in American business and a major competitor to the British commercial dominance in North American fur trade.  Expanding into many former British fur-trapping regions and trade routes, the company grew to monopolize the fur trade in the United States by 1830, and became one of the largest and wealthiest businesses in the country.

Fur trade: The fur trade is a worldwide industry dealing in the acquisition and sale of animal fur.  Since the establishment of a world fur market in the early modern period, furs of boreal, polar and cold temperate mammalian animals have been the most valued.  Historically the trade stimulated the exploration and colonization of Siberia, northern North America, and the South Shetland and South Sandwich Islands.

O'Chiese First Nation: The O'Chiese First Nation is an Anishinabe First Nation in Alberta, Canada.  The First Nation's homeland is the 14131.9 ha O'Chiese 203A Indian reserve, located approximately 52 km northwest of Rocky Mountain House.  Also reserved is the O'Chiese Cemetery 203A.  As of November 2013, the First Nation had the population of 1,250 registered people, of which the on-reserve population was 831 people.  The primary language spoken on the reserve is Anishinaabe language.  Though the ancestors of O'Chiese First Nation made the area about Baptiste River their winter camp site where they hunted moose and deer, and trapped small game for the Fur trade, they also migrated as far south as the Milk River in Montana in the summer.
