Thicklip Grey Mullet
Chelon labrosus
Britain's 'mullet cult' fish — famously wary, infuriatingly hard to hook, and worth a devoted following around harbours and marinas for exactly that reason. It will eat bread in plain sight off a harbour wall while seeing everything you do.
Seasons · Peak
Identifying features
- Thick, blunt upper lip covered with wart-like bumps (papillae) — the feature that names it
- Small downturned mouth at the bottom of a broad, flattened head
- Silvery-grey body with 4-6 darker lengthwise stripes and a white belly
- Golden patch on the gill cover, less bright than on the golden grey mullet
- Short pectoral fin that does not reach the eye when folded forward
Habits
- Grazes algae and biofilm off harbour walls, rocks and mud — the surface film is part of its diet
- Famously wary: it mouths a bait and rejects it before many anglers see the float move
- Feeds hardest on hot, settled days and on the first of the flood tide
- Travels in small, nervous shoals that spook at shadows and heavy footsteps
- Spawns offshore in winter; inshore fish are present much of the year
Distribution
Where to find them
- Harbour walls and marinas of Cornwall and South Wales
- Estuary mouths and tidal pools on the French Channel coast
- Mediterranean lagoons and harbour basins in summer
Where they live
How to catch them
Sight float fishing along harbour walls Shore
Rig: Light match rod, small crystal waggler locked 3-4 in above bottom, size 14 hook with bread flake, fine groundbait little and often
Bait/lure: Bread flake fished on sight
Key tip: Wear polarised glasses and watch the fish, not the float — a thicklip sucks bread in and blows it out before the float moves.
Light ledgering over rock and kelp Rock fishing
Rig: Light ledger setup from rock ledges with a 2-4 lb hooklength and size 12 hook, bait placed just in front of kelp edges
Bait/lure: Cheese paste or bread ball
Key tip: Move almost silently and cast nothing heavy — spook the shoal once and it is gone for the tide.

- Rod: 11-13 ft light match or coarse rod with a soft action
