Comber
Fish · Last reviewed 2026-08-23
A small, boldly barred sea bass of rock and rubble from the English Channel to South Africa, hermaphroditic in both directions at once, and the fish that takes the bait meant for something better.
Safety: injury while handling fish — minor injury.
Catching Comber

The cabrilla is a miniature sea bass, and it behaves like one. It is a slim, big-mouthed fish marked with seven or so dark vertical bars over a brown or reddish ground, with orange and blue lines along the head, and it sits in holes, under ledges and among rubble waiting for something to pass.
For an angler it is the fish that finds the bait first. Drop a strip of squid or a worm onto Canarian or Mediterranean rock and a cabrilla will usually take it before anything larger does, which makes it simultaneously the most reliable fish on the mark and the reason bigger baits get used.
Its biology is unusual even among the sea basses. It is a simultaneous hermaphrodite: an individual carries functional male and female tissue at the same time, rather than changing from one to the other as the sparids around it do. It is also far more wide-ranging and far deeper-living than its size suggests, recorded from the English Channel round the Cape of Good Hope to Natal and down to 500 m.

What experienced anglers do — 1 connection
How FishingHQ classifies this: practitioner consensus. Widely and independently recommended by experienced anglers and specialist sources. This is real angling knowledge, not proof: controlled evidence for it is limited, and FishingHQ records it as convention rather than as a demonstrated effect.
Light rock fishing
Cabrilla is the commonest small predator over Canarian and Mediterranean rock and dominates light-tackle catches there. A session dominated by it usually means the bait is too small or too far off the bottom for what was being fished for.

Where Comber is documented
Places where public sources describe this species as fished, with how it is fished and how strongly the evidence supports it. This is not a range map and it is not a recommendation — it is what has been written down about a fishery rather than a record of any individual catch, and being listed is never permission to fish.

What these strengths mean
- Recorded here
- At least one credible public account of this species being caught here. That is all it means.
Identification
No photograph of Comber has passed identity review yet, so none is shown. FishingHQ publishes a species photograph only once somebody has confirmed the animal in it against the species record’s own diagnostic features.
- Scientific name
- Serranus cabrilla
- Family
- Serranidae
- Water
- Saltwater
- Conservation status
- Least Concern
- Regions
- Mediterranean, Western Europe, Britain & Ireland, West Africa, East & Southern Africa
- Seven or so dark vertical bars over a brown, reddish or fawn ground, crossed by paler horizontal banding.
- Orange and blue-white lines running diagonally along the head and cheek.
- A large mouth and a pointed head for the size of fish — the outline of a bass rather than a bream.
- Single long dorsal with ten spines, and a squared-off tail.
Size
- Typical
- 80–250 g (3–9 oz)
- Large
- 300–500 g (11 oz–1.1 lb)
Exceptional: FishBase records a maximum of 40 cm
Lifecycle and reproduction
Demersal over an unusually wide depth range of about 5 to 500 m, holding to rock, rubble, seagrass and reef throughout. Medium resilience.
A simultaneous hermaphrodite: an individual carries functional male and female tissue at the same time. This is different from the sequential sex change of the sparids on the same ground and is worth knowing precisely because the two are easily conflated.
Feeding and senses
An ambush predator at small scale, taking crustaceans, small fish and worms from a lie among rock and rubble. It is quick to the bait, which is why it dominates catches on light tackle over rock.
Visual and very quick to movement, hunting from a lie in cover rather than in open water. It reacts to a bait landing faster than the larger fish on the same ground, which is the whole reason it dominates light-tackle catches over rock.
Through the year
Resident year-round over rock without a significant seasonal migration, which is part of why it is the most consistently encountered fish on Canarian and Mediterranean rock in any month of the year.
Distribution
Eastern Atlantic: English Channel southward round the Cape of Good Hope to Natal, South Africa, including Azores, Madeira and the Canary Islands. Also in the Mediterranean and western Black Sea and possibly in the Red Sea
This is a biological range — where the species occurs, not a prediction that you will catch one. To browse the fishing geography FishingHQ holds, start at fishing places.
Why anglers care
The commonest small predator on Canarian and Mediterranean rock and the fish most likely to take a bait intended for a bream or a porgy. Its significance to an angler is diagnostic as much as sporting: a session dominated by cabrilla usually means the bait is too small or too far off the bottom for what was actually being fished for.
Handling and returning
Spiny dorsal and sharp gill-cover edges on a fish small enough to be handled carelessly. Grip across the body and unhook with a disgorger; deep-hooked fish on small baits are common.
Safety
Injury while handling fish — Minor injury
Stiff dorsal spines and a sharp bony edge to the gill cover, both easy to catch a hand on when unhooking a small fish quickly.
What reduces it: Hold across the body from behind with the dorsal folded, keep fingers clear of the gill cover, and use a disgorger.

Serranus cabrilla is recorded as demersal over a very wide depth range, from about 5 m to 500 m, holding to rock, rubble and reef throughout — an unusually broad vertical range for a fish this size.
