How to identify

The numbers match the arrows on the illustration.

  1. Broad wings, almost form right angles.
  2. Row of 20–50 thorns from nape to first dorsal fin.
  3. 1–2 interdorsal thorns.
  4. Numerous dark spots which do not extend to very edge of disc.
  5. Frequently a a ring of dark spots present on the wings giving the appearance of an ‘eye-spot’.

Size & biology

  • Birth: 8–10cm.
  • Matures: female 49–70cm; male 40–66cm.
  • Max. TL: 80cm.
  • Oviparous, females lay 60–70 eggcases per year during summer on sandy or muddy substrates. Embryonic development takes 5–6 months.
  • Juveniles prey on small crustaceans; adults on larger crustaceans and teleosts.

Conservation status

Least Concern Global Least Concern Europe Least Concern Mediterranean

IUCN Red List: Global: Least Concern (2007) Europe: Least Concern (2015) Mediterranean: Least Concern (2016) A smaller bodied, widespread skate common in landings from fisheries and trawl surveys. Its small size and high fecundity may mean it is more resilient to fishing pressures than larger bodied skates.

Management

Subject to regulations under the CFP.

Commercial importance

Regularly taken as bycatch in multispecies trawl and gillnet fisheries across its range. Larger species are landed and sold for human consumption. 1-3
