Pacific Cod

Pacific Cod

Ranging from the Bering Sea and Aleutian Islands west to Japan and south along the North American coast, Pacific cod are the workhorse of cold-water bottom fishing across the northern Pacific.

Smaller on average than their Atlantic cousins, they school densely near the bottom and bite with enough consistency that the limiting factor is often freezer space, not patience.

The payoff is sweet, flaky white fillets — one of the better-eating fish in the sea.

Scientific Name: Gadus macrocephalus

Also known as Gray Cod, Grey Cod, True Cod, Alaska Cod

Physical Characteristics:
  • The single chin barbel — a fleshy whisker under the lower jaw — is the fastest field mark; combined with three separate dorsal fins and two anal fins, no other common bottom fish in the northern Pacific shares that silhouette.
  • Brown to grey on the back with irregular brown spots or pale blotches on the sides; belly fades to white or pale grey. Fins are dusky with white edges, most visible on the tail and anal fins.
  • The lateral line arches noticeably under the first two dorsal fins before running straight to the tail — a useful secondary ID feature when the fish is in hand.
  • Most fish run 20–25 inches and 5–10 lbs; the species can reach nearly 4 feet and 50 lbs, though fish that size are uncommon in recreational catches. Looks similar to Atlantic cod but runs smaller.

What to know

Habitat Distribution

  • Native to the northern Pacific — from the Bering Sea and Aleutian Islands east along the North American coast (rare south of northern California) and west through the Sea of Japan to the Yellow Sea.
  • Bottom-dwelling along the continental shelf and upper slope, with the bulk of the population living between 300 and 1,300 feet, though fish can be found anywhere from 40 to 1,800 feet depending on season and location.
  • Tied to cold boreal water: core habitat sits in the 43–48°F (6–9°C) range. At the southern edge of the range, populations are more vulnerable to warming ocean temperatures and may shift northward over time.

Specific Spots

  • Banks and shelf edges that funnel current concentrate forage — cod school up in these zones, and once you find the right depth band, numbers can be high.
  • Hard bottom — rock, gravel, shell hash — holds more invertebrates and small fish than soft mud, which is why the same rocky patches produce trip after trip while featureless bottom nearby goes quiet.
  • In spring, the seasonal shallowing movement brings fish into more accessible depths; by fall they've pushed back down. Marking fish on the sounder and dropping to their actual depth beats committing to a fixed zone all season.

Pacific Cod FAQ

Answers from onWater's species guide.

What are the best lures and bait for Pacific Cod?

Heavy jigs, diamond jigs, bucktails, and metal spoons in chrome or bright finishes, are the primary tool. Get the jig to the bottom and work it with short lifts; the weight needed to reach depth matters more than a subtle presentation at 300 feet.

What do Pacific Cod eat?

Larger fish key on other fish (herring, capelin, juvenile groundfish), octopus, and big crustaceans like crabs and shrimp, which is why heavy jigs that mimic a fleeing baitfish and squid strip baits both draw strikes reliably.

Where do Pacific Cod live?

Native to the northern Pacific, from the Bering Sea and Aleutian Islands east along the North American coast (rare south of northern California) and west through the Sea of Japan to the Yellow Sea.
