The lesser-spotted dogfish is the most reliably encountered shark species from Irish shore marks and is a familiar catch for anglers fishing Cork beaches, rocky outcrops, and mixed ground at night. While not large — most shore fish run between 1 and 3 lb — they are a consistent and obliging species that will accept a wide variety of baits and can make for busy sessions when conditions are right.
Dogfish are bottom-hugging predators that hunt primarily by scent, making them well suited to night fishing when they move more freely over the ground. Sandy and mixed beaches, particularly those with a decent depth within casting range, are the most productive shore marks. The species is active throughout the year but shows a clear preference for the warmer months, with April through October producing the most consistent fishing. Cold-water conditions in winter do not prevent catches but tend to slow the action.
Mackerel strip is the standout bait for dogfish, releasing a strong scent trail that draws fish from distance. Fresh or recently frozen mackerel cut into strips and mounted on a single hook size 1/0 to 3/0 is straightforward and effective. Lugworm and ragworm also account for dogfish, and these baits have the advantage of being readily available from tackle suppliers. A simple running leger or paternoster rig is all that is required.
Dogfish are entirely harmless to handle but their skin has a rough, abrasive texture similar to sandpaper that can cause skin irritation after a busy session. Handling them with wet hands and supporting the full length of the body before carefully unhooking is good practice. The species has a spiralling, rolling motion when hooked — wrapping around the trace — which can make unhooking messy. A damp cloth held around the fish helps control this. All dogfish should be returned alive.
