Source-derived summary

The Pacific cod (Gadus macrocephalus) is a species of ray-finned fish in the family Gadidae. It is a bottom-dwelling fish found in the northern Pacific Ocean, mainly on the continental shelf and upper slopes, to depths of about 900 m (3,000 ft). It can grow to a length of a meter or so and is found in large schools. They feed on clams, worms, crabs, shrimp, and juvenile fish. It is an important commercial food species and is also known as gray cod or grey cod, and grayfish or greyfish. Fishing for this species is regulated with quotas being allotted for hook and line fishing, pots, and bottom trawls. Fossils have been found in Canada near a Steller Sea lion fossil dating to the Pleistocene.

Description

It has three separate dorsal fins, and the catfish-like whiskers on its lower jaw. In appearance, it is similar to the Atlantic cod. A bottom dweller, it is found mainly along the continental shelf and upper slopes with a range around the rim of the North Pacific Ocean, from the Yellow Sea to the Bering Strait, along the Aleutian Islands, and south to about Los Angeles, down to depths of 900 m (3,000 ft; 500 fathoms).

Editorial summary

“Pacific cod” enters the record as species of fish. Crown Archives preserves that source wording while asking what Pacific, species and fish can confirm, complicate or overturn.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 202-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Pacific, species and fish.
Editorial analysis

Why this record matters

“Pacific cod” is worth following because a concise public description often conceals a longer documentary argument. Here, Pacific, species and fish provides the most credible route into that argument.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q783575. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
