Full dogfish guide
How to spot it, where it lives, how it is caught and how to cook it — the complete guide, in one easy read.
The dogfish is a genuine shark shrunk to hand size, prowling the seabed all along the Cornish coast. Mottled brown, rough as a rasp, it is unmistakable in the hand, and the chip shops have been quietly serving it for decades under a smarter name. Once you know what you are holding, it turns out to be one of the easier fish to land and to cook.
How to spot it
Hold one and there is no doubt. The back is a warm dark brown, finely peppered with small black spots, fading to a creamy underside, and the skin is rough enough to scuff your hands, like coarse sandpaper. The body is a true shark's in miniature, sleek and tapering, with the slung-low mouth and cat-like slit eyes that give the family its proper name of catshark. Most you will meet are hand-sized, though they can reach about 100cm. Spots, sleek shape and that file-rough skin together rule out anything else you are likely to land.
Where it lives
Dogfish are about as adaptable as a fish gets, settling over sand, rock and weed alike, in the shallows or deep, which is why they turn up so widely around Cornwall. You will find them from Tintagel, Trebarwith Strand and Port Isaac along the north coast through to Porthcurno, Lamorna, Newlyn and Mousehole in the far west, and on around Porthleven, Mullion, the Roseland and Mevagissey. The fishing runs from November through to July, a winter-and-spring fish that keeps you company through the cold, quiet months once most other species have moved off.
Catching it
Few fish are easier to tempt from the shore. A single weighted hook fished hard on the bottom is the whole method; leave the clever rigs at home. Dogfish hunt by scent, so an oily, reeking bait such as mackerel is hard for them to ignore, though sand eel, mussels, crab and prawn all account for fish too. Cast onto sand, rock or weed and give it time to find the bait. There is no minimum landing size in law, but it is poor form to kill a fish you will not use, so handle them with care, mind that abrasive skin, and slip any you are not eating straight back. They are at their most reliable on a cold, dark winter session when little else will oblige.
In the kitchen
This is the bold one, so cook it like you mean it. Dogfish flesh is dense, meaty and boneless, and it holds its shape where a flakier fish would collapse, which makes it the ideal fish for a proper curry: brown the chunks, then let them simmer in a coconut and tomato sauce heavy with ginger, chilli and curry leaves without falling to mush. Or do it the way the chippy does and batter thick fillets for rock salmon, crisp outside, juicy within. To prep it, take the skin off first: nick the tail, grip with a cloth and peel it back like a sock, then run a knife either side of the single central cartilage to lift two long fillets. There is no bony skeleton to fight, just that soft spine. It is a lean, high-protein fish, low in fat and rich in B12, which does it no harm at all.

FAQs
Quick fish questions
Short answers for the questions families and coastal readers often ask first.
What is dogfish sold as?
Dogfish is most often sold as rock salmon or huss, especially in fish and chip shops. So if you have enjoyed either at the seaside, there is a fair chance you have already eaten this small Cornish shark without ever knowing its real name.
Is dogfish sustainable?
The lesser spotted dogfish is one of our most abundant inshore sharks, and its numbers are healthy and increasing. Even so, as a slow-growing shark the MCS Good Fish Guide rates it only a middling (amber) choice rather than a low-concern one, so line-caught and locally landed beats trawled. The names rock salmon and huss have historically covered other, less robust species, so it is worth asking what you are actually buying.
Can you eat dogfish?
Absolutely. Dogfish gives dense, meaty, boneless white flesh, the same fish sold as rock salmon and huss. It takes batter brilliantly and is even better in a robust curry or stew, where its firmness means it holds together rather than breaking up.
What does dogfish taste like?
Dogfish has a mild flavour and a dense, meaty texture that stays in one piece during cooking. It is mild rather than strong, and with no bones to pick out, just a soft central cartilage, it is an easy and satisfying fish to eat.
How do you skin and fillet a dogfish?
Skin it first: nick through the skin at the tail, grip the end with a dry cloth and peel it forward off the body like removing a sock. Then run a knife down each side of the single central cartilage to take off two clean fillets. There is no true bony skeleton, which makes it one of the simpler fish to prepare.
What's the best bait for dogfish?
Dogfish hunt by scent, so oily, smelly baits such as mackerel are hard for them to resist. Sand eel, mussels, crab and prawn all work too. Fish them on a single weighted hook hard on the bottom over sand, rock or weed, and give the bait time to be found.
