Two fish anglers routinely mix up. Here is what actually separates them — and when and where you are likely to meet each.

Typical: 20–32 in, 5–15 lb
Key field mark: The single fleshy chin barbel and three separate dorsal fins are unique among Alaska bottomfish and immediately separate cod from the barbel-less, single-dorsal lingcod.

Typical: 2–3 ft
Quickest tell: Two well-separated dorsal fins and no chin barbel — despite the market name 'black cod', a Pacific cod has three dorsal fins and a prominent barbel under the chin.

Both run in Alaska — Aleutians & Alaska Peninsula — that is where telling them apart actually matters.
