Title: Sockeye salmon
Content:  been important in the diet and culture of the Coast Salish people of British Columbia. The largest spawning grounds in Asia are located on the Kamchatka Peninsula of the Russian Far East, especially on the Ozernaya River of the Kurile Lake, which accounts for nearly 90% of all Asian sockeye salmon production, and is recognized as the largest spawning ground outside of Alaska. Illegal fishing in Kamchatka is subject to environmental concern. Sockeye is almost never farmed. A facility in Langley, BC harvested its first salmon in March 2013, and continues to harvest farmed salmon from its inland facility.
Title: Smoked salmon
Content:  In the Atlantic basin all smoked salmon comes from the Atlantic salmon, much of it farmed in Norway, Scotland, Ireland and the east coast of Canada (particularly in the Bay of Fundy). In the Pacific, a variety of salmon species may be used. Because fish farming is prohibited by state law, all of Alaska's salmon species are wild Pacific species. Pacific species of salmon include chinook ("King"), sockeye ("red"), coho ("silver"), chum (keta), and pink ("humpback").
Title: Aquaculture of salmonids
Content:  Wild salmonids are captured from wild habitats using commercial fishing techniques. Most wild salmonids are caught in North American, Japanese, and Russian fisheries. The following table shows the changes in production of wild salmonids and farmed salmonids over a period of 25 years, as reported by the FAO. Russia, Japan and Alaska all operate major hatchery based stock enhancement programs that are really ocean ranching. The resulting fish hatchery fish are defined as "wild" for FAO and marketing purposes.
Title: Sockeye salmon
Content:  Sockeye salmon range as far south as the Columbia River in the eastern Pacific (although individuals have been spotted as far south as the 10 Mile River on the Mendocino Coast of California) and in northern Hokkaidō Island in Japan in the western Pacific. They range as far north as the Bathurst Inlet in the Canadian Arctic in the east and the Anadyr River in Siberia in the west. The farthest inland sockeye salmon travel is to Redfish Lake, Idaho, over 900 mi by river from the ocean and 6500 ft in elevation. In the United States, populations of sockeye salmon have been extirpated from Idaho and Oregon.
Title: Sockeye salmon
Content:  The total registered fisheries harvest of the sockeye in 2010 was some 170,000 tonnes, of which 115,000 tonnes were from the United States and the rest was equally divided between Canada and Russia. This corresponds to some 65 million fish in all, and to some 19% of the harvest of all Pacific salmon species by weight. Commercial fishermen in Alaska net this species using seines and gillnets for fresh or frozen fillet sales and canning. The annual catch can reach 30 million fish in Bristol Bay, Alaska, which is the site of the world's largest sockeye harvest. Sockeye salmon have

Content:  spawning grounds to the famous "June Hogs" (legendary Chinook salmon that weighed over 100 lb). Between 1985 and 2007, only an average of 18 sockeye salmon returned to Idaho each year. Serious conservation efforts by wildlife biologists and fish hatcheries have captured the few remaining wild sockeye salmon, collected their sperm and eggs, and in a laboratory, have them spawn. Instead of spawning naturally, these sockeye begin their lives in an incubator in a fishery biologist's laboratory. These baby salmon then are transported by ship, bypassing the dams. (The dams can hurt juvenile baby sockeye salmon with their powerful tides and 
Title: Environmental issues with salmon
Content:  Salmon fishery stocks are still abundant, and catches have been on the rise in recent decades, after the state of Alaska initiated limitations in 1972. Some of the most important Alaskan salmon sustainable wild fisheries are located near the Kenai River, Copper River, and in Bristol Bay. Fish farming of Pacific salmon is outlawed in the United States Exclusive Economic Zone, however, there is a substantial network of publicly funded hatcheries, and the State of Alaska's fisheries management system is viewed as  a leader in the management of wild fish stocks. In Canada, returning Skeena River wild salmon support commercial, subsistence and recreational fisheries, as well 
Title: Salmon
Content:   Salmon population levels are of concern in the Atlantic and in some parts of the Pacific. The population of wild salmon declined markedly in recent decades, especially North Atlantic populations, which spawn in the waters of western Europe and eastern Canada, and wild salmon in the Snake and Columbia River systems in northwestern United States. Alaska fishery stocks are still abundant, and catches have been on the rise in recent decades, after the state initiated limitations in 1972. Some of the most important Alaskan salmon sustainable wild fisheries are located near the Kenai River, Copper River, and in Bristol Bay. Fish farming of Pacific salmon is outlawed in the United States 
Title: Oncorhynchus
Content:  Poaching is a threat to Oncorhynchus salmon and steelhead populations in Russia. It is estimated that illegal catching of salmon is 1.5 times more than the reported catch. The Wild Salmon Center is working with Russian authorities to try to help improve traceability systems so that markets can distinguish between legal sustainable salmon and the illegal salmon. The Wild Salmon Center has secured some of its protected locations for the salmon populations. In efforts with the WWF, the Wild Salmon Center was also able to have a Sockeye Salmon fishery certified as completely sustainable in 2012. The Iturup Island Pink and Chum Salmon Fishery was first certified in 2009 and was the first Russian salmon fishery to receive certification in sustainability by MSC. Other fisheries that were certified by MSC include the Northeast Sakhalin Island Pink Salmon, certified in June 2012, and the Ozernaya River Sockeye Salmon, certified in September 2012. The Aniva Bay Pink Salmon and the Sakhalin Island Pink salmon are both under review by the MSC.
Title: Bristol Bay
Content:   Bristol Bay is home to the world's most abundant sockeye salmon fishery as well as strong runs of chum salmon, silver salmon, and king salmon, each occurring seasonally. Kings are usually the first to run up the river followed by reds and chums. Silvers and Pinks are the last to run up the river. On an international scale, sockeye salmon are a relatively rare creature. Like other wild salmon species, sockeye harvests fluctuate but comprise 4 to 7 percent of global salmon production and 13 to 20 percent of native salmon harvests. Between 2011 and 2014, sockeye accounted for 5 percent of the world's salmon harvest by volume and 15 percent of the world's wild salmon harvest.

Question: where does wild caught sockeye salmon come from?
Answer: the Northern Pacific Ocean.
