Bull Huss

Bull huss are the largest catshark in UK waters — a proper shark in miniature, built for rough ground and night tides.
Most common off the south and southwest coasts, they draw sea anglers who want something bigger and more deliberate than the ubiquitous lesser-spotted dogfish. Shore and boat fishing both produce fish, with the best catches coming over rocky reefs after dark.
Scientific Name: Scyliorhinus stellaris
Also known as Nursehound, Greater Spotted Dogfish, Large-Spotted Dogfish, Rock Salmon, Rock Eel, Flake
- Sandy to dark brown body covered in large, well-spaced dark spots — far fewer and bigger than the small-spotted dogfish's dense freckling.
- Broad, flattened head with large cat-like eyes; nasal flaps cover the nostrils but stop short of the mouth — the key ID feature separating huss from lesser-spotted dogfish.
- Two dorsal fins set far back toward the tail; rough, sandpaper-like skin covered in coarse denticles — handle with care.
- Average rod-caught fish run around 8 lb (3.6 kg); big specimens exceed 16 lb (7.3 kg), with the UK boat record standing at 22 lb 4 oz.
What to know
Habitat Distribution
- Native to the northeast Atlantic; found all around UK coasts but most abundant off the south and southwest of England and Wales, with patchy distribution in Scottish shelf waters.
- Rarely encountered in the North Sea; the Bristol Channel, Cornwall, and the wider Celtic Sea produce the most consistent catches for UK anglers.
- A bottom-dwelling species that favours rocky reefs, broken ground, and kelp beds — typically at depths of 20–60 m, though fish move into shallower water in summer.
- Relatively sedentary and site-faithful; individual fish tend to stay close to specific reef structures rather than making long migrations.
Key Locations
- Cornwall and the southwest peninsula — the most consistent shore and boat fishing in the UK, with fish present over reef ground from spring through autumn.
- Bristol Channel — a well-known huss fishery; the Welsh rod-caught record of 20 lb 8 oz came from off Aberystwyth, and charter boats out of South Wales regularly target the species.
- Minehead, Somerset — the UK boat record of 22 lb 4 oz was set here, underlining the Bristol Channel's reputation for big fish.
- Scottish shelf waters — patchy but present; huss turn up in the Celtic Sea approaches and around the southwest of Scotland, though far less commonly than in southern waters.
Specific Spots
- Rocky reefs and broken ground are the core habitat — huss use the gaps and gullies between boulders to flush out prey and shelter during daylight hours.
- Kelp forest edges and mixed rough-ground patches hold fish; the transition from clean sand to reef is a reliable feeding zone after dark.
- From the shore, fish directly into rough ground or alongside rock ledges where the seabed drops away — huss hug the bottom and follow the contour.
- In deeper water over 60 ft, anchor uptide of known reef marks and let baits settle hard on the bottom; huss locate food by scent rather than sight.
Bull Huss FAQ
Answers from onWater's species guide.
What are the best lures and bait for Bull Huss?
Fresh peeler crab or whole hardback crab is a top bait, the scent carries well on a tide and targets huss specifically over rough ground where dogfish are also present.
When is the best time to fish for Bull Huss?
Spring through autumn (roughly April to October) covers the main inshore season, when huss move into shallower reef ground and shore catches peak. Summer months see juveniles schooling in shallow water; larger adults are more accessible to boat anglers over deeper reef through summer and into autumn.
How do you catch Bull Huss?
Most UK anglers target bull huss from charter boats anchored uptide of known reef marks, fishing large scent-heavy baits hard on the bottom after dark. Shore fishing from rock ledges and rough-ground marks after sunset also produces fish, particularly in the southwest.
What do Bull Huss eat?
Crustaceans and molluscs form a large part of the diet, crabs, prawns, and shellfish, which is why fresh peeler or hardback crab is one of the most reliable baits on UK marks.
Where do Bull Huss live?
Native to the northeast Atlantic; found all around UK coasts but most abundant off the south and southwest of England and Wales, with patchy distribution in Scottish shelf waters.
