industry in Alaska and the history of growth. The influence of the Katmai Volcano Explosion in 1912 and the influenza epidemic in 1919 decimated the Naknek people and area. According to oral history, there were only about three original families left at that time. World War Two On July 7, Alaskans witnessed conflict as Japanese fishing vessels entered the waters of Bristol Bay with 10,000-ton fishing trawlers to harvest salmon. At that time, the Fisheries Bureau prohibited the use of motorized vessels, fish traps, and purse seines in Alaska. This was to ensure a 50% escapement of the spawning salmon, to guarantee their sustainability. The Japanese fleet was composed of diesel-powered steel vessels. The Japanese had a technological advantage over the American fisherman and dominated the bay that summer. In 1938, the United States agreed with Japan that the Japanese would refrain from fishing in Alaskan waters. This agreement was honored until Japan and the United States entered World War 2. In the 1950s, Japan was strengthening its fishing presence in the Pacific; the US, Canada, and Japan passed the North Pacific Fisheries Treaty. This treaty managed the resources of the region jointly to preserve the future generations of fish. This agreement is the model for international fisheries regulations today. Industry 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. Commercial fishing Bristol Bay is home to the world's largest salmon run. All five Eastern Pacific species spawn in the bay's freshwater tributaries. Commercial fisheries include the world's largest sockeye salmon fishery. The Kvijack drains from Lake Iliamna, which is downstream of the deposit. Along with herring and other fisheries, salmon account for nearly 75% of local jobs. During the first 50 years of commercial salmon fishing in Bristol Bay, the fishing
