In high-yield years, salmon accounts for more than 70% of the total output value of American salmon, of which more than 95% is produced in Alaska waters. Salmon fishing outside Alaska is only found in the inland waters of Washington State, where local fishermen intercept salmon swimming to the Fraser River in British Columbia, Canada.

Salmon can be caught almost all summer. The fishing season for Alaskan salmon begins in mid-May, near copper river, near prince william sound. Although the output here is relatively small, about 2000 to 3000 tons, the price is higher than other salmon, because the salmon produced here is bigger and has higher oil content.

The biggest salmon fishing took place in Bristol Bay in western Alaska in early July. In high-yield years, more than 80,000 tons of salmon can be caught in this water area, and sometimes1.50,000 tons can be caught in the peak period. Such a large-scale fishing in a short time can easily saturate the products of the processing plants, forcing them to transport Bristol salmon to other processing plants in Alaska. Although the total output of Bristol salmon is considerable, the number of salmon is small, with an average of about 2.5 kg.

The salmon fishing season in southeastern Alaska and Washington State ends in August. Salmon caught in these waters are larger and have higher oil content. Similar to other salmon, the oil content and price mainly depend on the distance between salmon migration and spawning sites. The farther the migration, the higher the oil content. The oil content of a salmon caught in Cooper River can be as high as 12%, and the price can be higher than that of a salmon caught in Bristol Bay with only oil content.
