Saltwater · Spring and autumn; summer in deeper water
Thornback Ray
Raja clavata
Britain's number one shore ray — the 'roker' of English beaches — and a regular boat catch all around Ireland and the Channel. Its back and tail are armoured with thorns, but they are only sharp, not venomous. Numbers have recovered well under catch-and-release, and most anglers return them.
Seasons · Peak
Identifying features
- Diamond-shaped disc with a pointed snout and a long, thick tail
- Rows of sharp curved thorns along the tail and down the back
- Rough, sandpapery skin with extra thorn-like buttons, especially on mature females
- Mottled brown, grey or olive marbling on top, plain white underneath
- No sting or venom barb — the thorns can scratch but are harmless beyond that
Habits
- Lies half-buried on sand and gravel by day, hunting more actively at night
- Feeds on crabs, shrimps, sandeels and small flatfish and whiting
- Moves into shallower beach water in spring and autumn, deeper in high summer
- Females lay horned egg cases — the 'mermaid's purses' found on beaches
- Best released carefully at the water's edge; support the body, never lift by the tail
Distribution
Where to find them
- Shingle and sand beaches of southern England and Ireland in spring
- Thames Estuary and Solent boat marks over mixed ground
- Dutch and German North Sea beaches in autumn
Where they live
How to catch them
Beach casting with a pulley or up-and-over rig Shore
Rig: Beachcaster with a pulley or up-and-over rig, size 2/0-4/0 hook and a 5-6 oz grip lead cast onto sand or mixed ground
Bait/lure: Fish strips, sandeel or crab
Key tip: Fish the last two hours of the flood into darkness in spring — rays patrol very shallow water at night.
Downtide ledgering over banks Boat
Rig: Uptider or 12-20 lb boat rod, running ledger with a 4/0 hook and enough lead to hold in the tide
Bait/lure: Bluey or mackerel strip, whole sandeel
Key tip: Let the ray move off with the bait before lifting in — thornbacks sit on a bait before taking it properly.
