Identification

  • Sockeye lack the large spots of other Pacific salmon: at most there is fine black speckling on the back, and no spots on the fins or tail.[1]
    What the source says
    “Some fine black speckling may occur on the back, but the large spots typical of other Pacific salmon are absent. There are no spots on the fins, including the tail.”
  • Spawning colour: returning sockeye turn bright red with green heads, which is why Alaskans call them "red" salmon. Spawning males get a humped back and hooked jaws.[1]
    What the source says
    “As sockeye salmon return to their freshwater spawning grounds, their heads turn green and their bodies turn bright red, hence their other common name in Alaska is “red” salmon. Spawning males develop a humped back and hooked jaws filled with tiny, visible teeth.”
  • Alaska's angler tip: spawning sockeye are deep red with a greenish head, but the tail stays without much colour. Sockeye have a white mouth with a white gum line.[2]
    What the source says
    “Male and female spawning sockeye develop a deep red coloration on their body. Their head turns a greenish color, while their tail remains devoid of significant coloration. The male develops pronounced shoulders and a large kype. Spawning and ocean-phase sockeye have a white mouth with a white gum-line.”

Habitat and range

  • On the west coast of North America, sockeye range from the Klamath River in Oregon to Point Hope in northwest Alaska.[3]
    What the source says
    “On the west coast of North America, sockeye salmon range from the Klamath River in Oregon to Point Hope in northwestern Alaska.”
  • Some sockeye never go to sea; in the Pacific Northwest these freshwater sockeye are called kokanee.[1]
    What the source says
    “Some sockeye salmon are not anadromous and spend their entire lives in freshwater. In the Pacific Northwest, non-anadromous sockeye are known as "kokanee."”

Life history

  • In Alaska most sockeye return to spawn in June and July, in rivers, streams and upwelling areas along lake beaches.[3]
    What the source says
    “In Alaska, most sockeye salmon return to spawn in June and July in freshwater drainages that contain one or more lakes. Spawning itself usually occurs in rivers, streams, and upwelling areas along lake beaches.”
  • At sea, sockeye keep eating zooplankton but also take small fish and sometimes squid.[1]
    What the source says
    “In the ocean, sockeye salmon continue to feed on zooplankton but also eat larval and small adult fishes and occasionally squid.”

Status, protections and rules

Legal status and rules as the agency stated them on the date read. Rules change: check the current regulations for the water.

  • Under the ESA, NOAA Fisheries lists the Snake River sockeye as endangered and the Ozette Lake sockeye as threatened.[4]
    What the source says
    “ESA Endangered Snake River ESU ESA Threatened Ozette Lake ESU”

Fishing for it: what the agencies say

What agencies and extension services say about catching it, with the source for each line.

  • Alaska's best-known sockeye sport fisheries are on the Kenai River and its tributary the Russian River; the Kasilof River, Bristol Bay rivers and Kodiak Island are also popular.[5]
    What the source says
    “Probably the best known sport fisheries with the greatest participation occur during the return of sockeye salmon to the Kenai River and one of its tributaries the Russian River on the Kenai Peninsula. Other popular areas include the Kasilof River on the Kenai Peninsula as well as the various river systems within Bristol Bay and Kodiak Island.”
General advice (ours, not an agency's)
  • Check the agency's run timing, emergency orders and in-season changes before you travel: openings are set by water, section and date.
  • Confirm which fish you may keep and how to tell wild from hatchery fish on that water.
  • A local guide or shop will know where the fish are in the run this week.

Water temperature

Warm water stresses trout, char and salmon. These are the published temperature lines we show on every gauge, chosen state first: the state agency's own where it publishes one, otherwise federal guidance (said so). Each water page applies them to the gauge's live reading; the flow and temperature checker does the same for any gauge.
