Pink Salmon

U.S. wild-caught pink salmon is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations.

NOAA Fisheries works in cooperation with federal, state, tribal, and Canadian officials to manage these commercial, recreational, and tribal harvest of salmon and steelhead in ocean and inland waters of the West Coast and Alaska. To learn more about management of these fisheries, visit our West Coast and Alaska fisheries management pages.

• Pink salmon are the smallest of the Pacific salmon found in North America, weighing between 3.5 and 5 pounds, with an average length of 20 to 25 inches.
• Pink salmon can be distinguished from other Pacific salmon by the large dark oval spots on their back and entire tail fin as well as their general coloring and form.
• In the sea, pink salmon are steel blue to blue-green on the back, silver on the sides, and white on the belly.
• Breeding males become dark on the back and red with brownish green blotches on the sides.
• Males also develop a hump on their back, which is why they are often called “humpback” salmon.
• Breeding females are similar but lack a dorsal hump and are less distinctly colored.

• Pink salmon are anadromous – they hatch in freshwater streams and rivers then migrate out to the saltwater environment of the ocean to feed and grow.
• Unlike coho, Chinook, or sockeye salmon, pink salmon do not reside in fresh water for an extended period.
• Young pink salmon (fry) typically migrate directly to estuarine and marine waters soon after they are born.
• Once they reach the ocean, they feed voraciously and grow rapidly. In fact, they’re among the fastest growing of the Pacific salmon species.
• After about 1½ years of feeding and growing in the ocean, maturing pink salmon return to fresh water to spawn, usually from August to October.
• Females construct nests (redds) in the riverbed by turning on their sides and vigorously flexing their bodies and tails, digging a shallow hole.
• Females deposit between 1,200 and 1,900 eggs in the redds, which the males then fertilize.
• The female stays and defends her redd from other females until she dies, usually within two weeks.
• All pink salmon die after they spawn.
• They typically spawn at the age of 2.
• Because the pink salmon life cycle is so regular, independent populations spawn in even and odd years. For example, in the southern part of their range, they usually spawn in odd years in most river systems. However, pink salmon do spawn in even years in some Puget Sound rivers.
• Throughout most of Alaska, there is no dominant year, except in the northwestern part of Alaska where even-year runs predominate.
• Pink salmon feed on small crustaceans, zooplankton (tiny floating animals), squid, and small fish.
• In fresh water, aquatic invertebrates, other fishes, birds, and small mammals prey on pink salmon eggs, alevins, and fry.
• In the ocean, other fishes (including other Pacific salmon) and coastal seabirds prey on pink salmon fry and juveniles.
• Marine mammals, sharks, other fishes (such as Pacific halibut), and humpback whales feed on adult pink salmon.
• In freshwater spawning habitats, bears are predators of adult pink salmon. Wolves, river otters, and bald eagles will also occasionally eat pre-spawning adult pinks.
• After salmon spawn and die, salmon carcasses are a valuable source of energy and nutrients to the river ecosystem. Carcasses have been shown to improve newly hatched salmon growth and survival by contributing nitrogen and phosphorous compounds to streams.

• Pink salmon are found on both sides of the North Pacific, from Alaska to Puget Sound in Washington State and from Russia to North Korea.
• In North America, they’re found from the Arctic coast in Alaska and territories in Canada to central California, although they do not reproduce in significant numbers south of Puget Sound.

• NOAA Fisheries and the Pacific Fishery Management Council manage pink salmon on the West Coast.
• Managed under the Pacific Coast Salmon Plan:
  • Every year, the council reviews reports of the previous fishing season and current estimates of salmon abundance. Using this information, they make recommendations for management of the upcoming fishing season.
  • Their general goal is to allow fishermen to harvest the maximum amount of salmon that will support the fishery while preventing overharvest of the resource and ensuring that salmon populations with low abundance can rebuild.
  • Specific management measures vary year to year depending on current salmon abundance, and include size limits, season length, quotas, and gear restrictions.
  • The council usually increases harvest limits for pink salmon in odd years when more adults are returning to spawn.
  • Management of pink salmon must also comply with laws such as the Endangered Species Act.
  • Final recommendations are implemented by NOAA Fisheries. Check here for the current season’s management. State and tribal managers use council management recommendations to shape their policies for inland fisheries, to ensure that conservation objectives are met.
• NOAA Fisheries and the North Pacific Fishery Management Council manage pink salmon in Alaska.
• Managed under the Fishery Management Plan for Salmon Fisheries in the EEZ off the Coast of Alaska:
  • All management of the salmon fisheries in federal waters is delegated to the State of Alaska, which is also responsible for managing the commercial, recreational, and subsistence fisheries for salmon in state waters. This ensures that management is consistent throughout salmon’s range.
    • Managers regulate the fishery based on escapement goals to ensure harvests are sustainable. They want enough salmon to be able to escape the fishery and return to fresh water to spawn and replenish the population.
    • Salmon fishery management largely relies on in-season assessment of how many salmon return to fresh water to spawn.
    • Managers set harvest levels based on these returns. When abundance is high and the number of fish returning is much higher than that needed to meet escapement goals, harvest levels are set higher.
    • In years of low abundance, harvest levels are lowered.
  • During the fishing season, scientists monitor catch and escapement, comparing current returns with those from previous years, to keep an eye on abundance and actively manage the fishery.
• Off the West Coast and in Alaska, the Pacific Salmon Treaty and the Pacific Salmon Commission help coordinate management, research, and enhancement of shared U.S. and international salmon stocks, including pink salmon.

• Commercial fishery:
  • In 2019, commercial harvest of pink salmon totaled approximately 396 million pounds and were valued at more than $106 million, according to the NOAA Fisheries commercial fishing landings database.
  • Almost all the pink salmon harvested in the United States comes from Alaska fisheries.
  • Small numbers of pink salmon are also harvested off the West Coast, mainly Washington, especially in odd-numbered years (see the Science section for more about pink salmon’s unique two-year life cycle).
• Gear types, habitat impacts, and bycatch:
  • Purse seines, gillnets, and reef nets are used to catch pink salmon.
  • Purse seiners catch salmon by encircling them with a long net and drawing the bottom closed to capture the fish.
  • Gillnetters catch salmon by setting curtain-like nets perpendicular to the pink salmon trajectory as they migrate along the coast toward fresh water.
  • Fishing gear used to catch pink salmon rarely contacts the ocean floor and has little impact on habitat.
  • Bycatch is low and usually consists of other salmon species.
• Recreational fishery:
  • Salmon are a favorite catch of recreational fishermen.
  • Recreational fishermen use a variety of fishing gear to harvest pink salmon.
  • While their relatively small size makes them less popular with sport anglers than other salmon species, pink salmon are excellent fish to catch because they’re aggressive and make a nice, mild-tasting meal.
  • To ensure recreational fisheries are sustainable, West Coast anglers are only allowed to keep a certain number of salmon per fishing trip.
  • In Alaska, regulations vary by area and individual fisheries.
  • Recreational fisheries in high-use areas (Cook Inlet, Southeast Alaska, Copper River) are regulated through management plans that allocate fish between competing commercial and recreational fishermen.
• Subsistence fishery:
  • Salmon is an important source of spiritual and physical sustenance for Western Indian tribes and Alaska natives, and salmon are culturally important to many other residents of these areas.
  • Subsistence fishermen use a variety of fishing gear to harvest pink salmon.
