Blackbellied angler: identification, habitat and fishing guide

Lophius budegassa

Black-bellied anglerfish is a benthic predator resembling white anglerfish. Identification relies on several features rather than the common name “monkfish” alone.

Catalogue names : Blackbellied angler. Forms and names may vary between habitats.

Editorial review : · This species guide is not permission to fish. Read the precautions below and check the current rules for your location before targeting a species. Some species or populations are protected.

Geographical distribution

FAO-AdriaMed places the species in the eastern Atlantic from England and the North Sea to Senegal, and throughout the Mediterranean, with detailed records for the Adriatic.

  • Documented presence : Eastern Atlantic
  • Documented presence : North Sea
  • Documented presence : Mediterranean Sea
  • Documented presence : Adriatic Sea

Documented areas, not an exhaustive list. Presence in a region does not imply presence in every water body or permission to fish.

Distribution sources

Identification

A very broad flattened forebody, fishing filament with a simple appendage and dark peritoneum. The peritoneum is internal: do not cut a fish open to check this detail alone.

Havstovan confirms that the terminal lure is simple, unlike the forked lure of Lophius piscatorius; these anglerfish resemble one another and require careful examination.

Habitat

Seabeds, particularly soft bottoms, in the eastern Atlantic and Mediterranean, on the continental shelf and slope.

Diet

Mainly fish; Adriatic studies also report cephalopods and occasional crustaceans.

In the Celtic Sea, Issac and colleagues found a diet varying with size and area, with an important role for benthic prey and crustaceans. This regional finding does not demonstrate a preference for an angling bait.

Behaviour

A benthic predator using a dorsal ray modified into a lure to attract prey.

Indicative biological size

20–40 cm, the common size in the FAO guide; a descriptive indication.

Fishing context and precautions

Sea Angling Ireland treats Lophius budegassa and Lophius piscatorius together: mainly incidental bottom encounters on sand or mud between rocks, mackerel bait and a wire trace. Its drifting presentation with a long snood remains a collective method, offered here as an indicative adaptation without demonstrated effectiveness specific to black-bellied anglerfish.

FIPSAS also names Lophius budegassa in its boat-angling documents. This recognition does not transfer any Italian rule to France. Prepare for landing a fish with a large toothed head, avoid seeking deep catches whose outcome cannot be managed, and do not improvise invasive procedures.

A distinctive feature

Its natural lure has a simple appendage, unlike the forked appendage of white anglerfish.
