Flathead grey mullet: identification, habitat and fishing guide

Mugil cephalus

Flathead grey mullet have a characteristic head and inhabit varied environments. This sheet suggests observing a lagoon margin before deciding where to place a bait, without automatically applying methods used for other mullets.

Catalogue names : Flathead grey mullet. 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

Very widely distributed along tropical, subtropical and temperate coasts of the Atlantic, Indian and Pacific oceans, occurring in the Mediterranean and Black Sea. DORIS retains uncertainty over some Bahamas and Caribbean records.

Identification

Mugil cephalus, also called flathead grey mullet, has a broad, flattened head and well-developed adipose eyelids. Its lips remain thin. A robust body alone is insufficient: compare the eyes and profile with mullets of the genus Chelon before recording the species.

Habitat

It inhabits coastal waters, lagoons and less salty waters. The setting chosen here is an accessible lagoon margin with clear bottom and somewhere to land the fish. Movements between sea and lagoon vary; the passage seasons described for this fish do not apply to all mullets.

Diet

Microalgae, organic detritus and small bottom-dwelling invertebrates; young fish take zooplankton among other foods.

Behaviour

It uses organic resources on the bottom and small organisms, among other food. For this suggestion, observing feeding matters before choosing bait: fish rooting around, a group passing through or activity near the surface. A bottom rig is useless if it remains far from the route actually used.

Indicative biological size

Adults commonly measure 40–60 cm according to DORIS; this biological range is not a legal size limit.

Fishing context and precautions

  1. Locate clean bottom near an area where fish stop. Prepare a light sliding rig with a weight stopped by a swivel and a hooklength ending in a single hook.
  2. Present a small, securely attached piece of bread only if observation suggests interest in this food, or compare a marine worm. Keep the hook point free.
  3. Maintain enough tension to read movement without constantly pulling the bait. Check that it remains attached after uncertain contact and compare another depth under a float if fish are feeding above the bottom.
  4. At an established pull, make contact progressively and use the drag to absorb the run. Bring the fish into the landing net without hoisting it onto the bank.

A distinctive feature

Part of its stomach acts like a gizzard and helps process material ingested with sediment.
