Identification

Look for

  1. No large adipose flap on the head — the key field mark separating it from golden tilefish, which has one
  2. A narrow gold stripe underlined in blue running from the snout to the eye — the source of the common name
  3. Dull olive-gray back, white underside, long continuous dorsal and anal fins

Local waters

Continental shelf break and upper slope, 98–774 feet deep, concentrated between the Hudson and Veatch canyons in the Mid-Atlantic

Primarily a boat fishery here — typically fished by offshore boat.

When to fish

Typically present: spring, summer, fall, winter

Deep-dropped year-round when conditions and the federal season allow — a serious boat/gear commitment, not a casual trip, and a real component of the same fishery as the already-published golden tilefish.

Water temperature

The water, not the calendar, sets the season here — a warm October or a cold snap moves these bands.

How to catch it

Primarily a boat fishery here — typically fished by offshore boat. Technique notes for this species have not been written yet; the baits and rigs below are the documented starting points.

Bait & lures

  • Deep-dropped squid or cut bait on electric or heavy conventional tackle

On the table

Eat with caution — check current Virginia fish consumption advisories for the specific waterbody before eating.

  • Confirmed live: the same federal recreational tilefish permit golden tilefish requires (Private Recreational Tilefish Permit, or Charter/Party Tilefish Permit for for-hire trips) also covers blueline tilefish, plus mandatory trip reporting. 2026 recreational season is May 15–November 14; possession limit is 3/person/trip on private boats, 5/person/trip on charter boats, 7/person/trip on party boats, with no minimum size. Tilefish as a group is named on the FDA/EPA's 'Choices to Avoid' mercury list alongside shark, swordfish, king mackerel, and marlin — this project could not get a clean direct fetch of the current live FDA chart, but this is corroborated consistently across multiple independent secondary sources.

Cleaning, chilling, and cooking a legal catch covers the steps between the cooler and the pan.

Spots marked “habitat match” share this species' water type, habitat, and methods — not a report that it has been caught there.
