Stonebream
Fish · Last reviewed 2026-08-27
Stinkvis: a dark, deep-bodied, weed-grazing kyphosid of the KwaZulu-Natal and Eastern Cape gullies that is easy to catch, hard on tackle, and named for exactly what it smells like.
Catching Stonebream
Everything here on fishing for it. Each entry opens the page behind it.
The stonebream is called stinker and stinkvis and there is no delicate way to explain why.
IT IS A WEED-GRAZER, and that is the whole of it. A kyphosid — a sea chub, related to the drummers and rudderfish of other coasts — feeding on algae cropped off rock in shallow water, with a long gut full of fermenting plant matter. A grazing fish smells like a grazing fish, and the flesh follows the diet.
IT IS DARK, DEEP-BODIED AND POWERFUL. Grey to almost black, oval, with a small mouth and a compact head, reaching about fifty centimetres and 2.6 kg and aged to ten years.
IT FIGHTS FAR ABOVE ITS SIZE on light tackle, which is why it has a following despite the smell. In a shallow gully with a swell running, a stonebream in a kelp bed is a genuinely hard fish to land.
IT IS A RECREATIONAL SPECIES with no minimum size and a daily bag limit, and it has no IUCN assessment.
AND THE BAIT IS THE INTERESTING PART. A dedicated weed-grazer is caught on weed — a small ball of green algae on a light hook — which is a technique South African rock anglers share with Mediterranean salema fishers and with British mullet anglers, and which almost nobody outside those groups has ever tried.
Identification
No photograph of Stonebream 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
- Neoscorpis lithophilus
- Family
- Kyphosidae
- Water
- Saltwater
- Conservation status
- Not assessed
- Regions
- East & Southern Africa
- GREY TO ALMOST BLACK, deep-bodied and oval, with a small mouth and compact head.
- A KYPHOSID RATHER THAN A SPARID — a sea chub, related to the drummers and rudderfish, and shaped like one.
- SMALL MOUTH WITH FINE CROPPING TEETH for grazing algae off rock.
- TO ABOUT 50 CM AND 2.6 KG, aged to 10 years.
- THE SMELL, once the fish is out of the water, is diagnostic and is the reason for both local names.
Size
- Typical
- 25–40 cm. No minimum size is set for this species.
- Large
- Over 45 cm is a large stonebream.
Exceptional: FishBase records a maximum length of 50 cm and 2.6 kg, with fish aged to 10 years.
How South African sea-fishing rules work
SOUTH AFRICA REGULATES SEA FISHING SPECIES BY SPECIES, WHICH IS NOT HOW MOST COUNTRIES DO IT.
A recreational permit is the entry ticket and not the whole of it. On top of it sits a minimum size and a daily bag limit SET PER FISH, a closed season on a small number of species, and a cumulative daily cap across everything caught — so being inside the limit for each species separately does not put you inside the limit overall.
THERE IS A CAP ON HOOKS on a rod-and-line permit. A spearfishing permit is separate, allows no breathing apparatus beyond a snorkel, and PROHIBITS SPEARFISHING IN AN ESTUARY — a flat ban rather than a limit, and the rule visitors most often do not know.
A LANDED FISH MUST KEEP ITS HEAD AND TAIL so its length can be checked. Nothing caught on a recreational permit may be sold by anyone. And a small list of species may not be caught, landed or possessed at all.
FISHINGHQ DOES NOT PRINT THE FIGURES, and the reason is on this page rather than in a policy document: the department's own guidance says adjustments may be forthcoming given the acknowledged crisis of linefish, the numbers differ by species and by area and by whether you were standing on a beach or sitting in a boat, and a stale figure on a fishing site is worse than no figure at all. Get the current position from the Department of Forestry, Fisheries and the Environment, and get the protected-area position from whichever body manages the stretch of coast you are on.

Lifecycle and reproduction
A shallow-water grazing kyphosid aged to about ten years — a faster life history than the long-lived sparids on the same rock, which is consistent with its daily bag limit and the absence of any size limit.
Spawns inshore with pelagic eggs and larvae. Kyphosid juveniles are frequently associated with drifting weed and surface debris before settling onto reef, which is part of why the family is so widely distributed.
Feeding and senses
A dedicated herbivore grazing algae from rock in shallow water, with a long gut for fermenting plant material. That specialisation is why weed is the effective bait and why fish and squid baits are largely ignored — a technique shared with Mediterranean salema fishing and with British mullet angling, and almost unknown outside those traditions.
Close-range vision over shallow reef in aerated water, grazing a known patch of rock rather than searching for prey. A grazer does not need to detect movement at distance, which is why nothing worked or retrieved interests it and why the effective bait is the thing it already eats.
Through the year
Resident in shallow gullies and on rock through the year, with no migration to plan around, so availability is a swell question rather than a seasonal one. What does vary is the weed: a grazing fish follows its algae, and a gully that has been scoured bare by a winter sea holds fewer of them until it grows back.
Distribution
Western Indian Ocean, from Inhaca Island in Mozambique to False Bay in South Africa, demersal on shallow rocky ground. No IUCN assessment has been made.
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
A hard-fighting light-tackle rock species with a devoted following on the KwaZulu-Natal and Eastern Cape coasts, and a fish almost nobody eats. It is a recreational species that may not be sold, at a daily bag limit with no minimum size. Its technical interest is that it is one of the few South African species caught on WEED, which puts it in the same small group as Mediterranean salema and British mullet.
Handling and returning
Easy to handle and usually released.
SMALL HOOKS AND SMALL BAITS for a small mouth.
WET HANDS AND A QUICK RETURN. It goes back into the water, not from the ledge.
NOTHING ABOUT IT IS DANGEROUS beyond stiff dorsal spines.
AND IF YOU ARE KEEPING IT, GUT AND ICE IT IMMEDIATELY. A herbivore's gut contents are what the flesh takes its character from, and the difference between a fish gutted on the rock and one carried home whole is not subtle.
Check the rules before you fish
Fishing laws, bylaws, access rules, seasons, bait restrictions and permitted methods vary by location and can change. Check the current rules from the relevant authority and the water you intend to fish before fishing.
Check with:
- Current national or regional law for where you are fishing
- Current local bylaws
- The relevant fisheries authority
- The landowner, club or fishery whose water it is
- Any restrictions specific to the species or the method you intend to use

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.
