Trigla lyra Linnaeus, 1758

Thirty Piper gurnard, Triglidae (Tab. III), were collected from 21 to 28 Oct. 2018 during the EVHOE survey, using a bottom trawl. They were collected in the southern and central Bay of Biscay ( Fig. 3J ). The fresh specimens measured 115- 347 mm TL. A specimen measuring 295 mm TL, 284 mm FL, 238 mm SL, 74 mm HL and weighed 200 g ( Fig. 4E ) collected at Station W0561 was preserved with the collection No. MNHN-IC 2020-0093 and a tissue sample was preserved under No. BPS-4245. Recorded by P. Lorance and S.P. Iglésias. Records of this species were common in the past in the Bay of Biscay. Postel and Du Buit (1965) listed Trigla lyra as observed “daily” in the fishmarket of Concarneau in July-August 1964, with a maximum recorded size of 48 cm. This species became increasingly rare in subsequent decades, which was postulated to be due to its sensitivity to bottom trawling ( Nouvel, 1950; Quéro et al., 1984, 1989). Numbers caught during the EVHOE surveys have increased in recent years, which may suggest a possible recovery of the species ( Fig. 10 ).
