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

Typical: 12–20 in, 1–5 lb
Key field mark: These are the larger continental-shelf rockfish; key the very long protruding jaw to bocaccio, the pink lateral stripe to chilipepper, and rough red-with-black mottling plus a scaly jaw to vermilion (vermilion's vertical anal-fin edge and gray-less lateral line separate it from canary).

Typical: 20–28 in, 5–12 lb
Key field mark: The glowing yellow iris plus rough raspy bony ridges above the eyes confirm the protected Yelloweye (release required) over the similarly red canary (gray lateral stripe, smooth head) and vermilion (red iris, black-mottled body).

Both run in Northern California — that is where telling them apart actually matters.
