About Thornback ray fishing
The thornback ray is a demersal cartilaginous fish belonging to the family Rajidae, easily recognised by its distinctive rhomboid, kite-shaped body with pointed wing-tips and a long, thorny tail. Reaching a maximum length of 105 cm and a maximum weight of 18 kg, this species features a brownish upper surface patterned with dark spots and yellow patches, alongside sharp defensive spines and characteristic bucklers in mature individuals. It inhabits coastal and shelf waters across sandy, muddy, and gravelly seabeds, undertaking seasonal bathymetric migrations from deeper wintering grounds to shallow inshore areas during spring. As a nocturnal benthic predator, it feeds primarily on crustaceans and small fishes, making it a popular target for sea anglers fishing from the shore or small boats.

When to fish for Thornback ray
How to catch Thornback ray
Tips for catching Thornback ray
To target thornback rays successfully, focus your efforts over clean sandy, muddy, or fine gravel grounds in coastal waters, particularly during their spring inshore migration. As these rays are primarily nocturnal and feed close to the seabed, bottom fishing from a drifting boat or heavy surfcasting from open beaches during dusk and night hours yields the best results. Presenting large, oily baits such as fresh mackerel strips, squid chunks, or whole lugworms on a sliding ledger rig helps attract them through scent detection. Keep your tackle robust with a strong running lead setup to handle their powerful resistance on the retrieve without alerting them to unnatural tension.
