Weight–length relationships for eight species of the family Triglidae discarded on the south coast of Portugal

Weight–length relationships for eight species of the family Triglidae discarded on the south... Summary Gurnards or triglids are medium‐size marine bottom fishes that live in tropical and temperate seas. Four genera (Aspitrigla, Chelidonichthys, Lepidotrigla, Trigla) and eight species are found in the eastern Atlantic. In this study, we report the weight–length relationships for eight species, with 75 specimens of A. cuculus, 45 of C. obscurus, 84 C. gurnardus, 21 C. lucernus, 45 C. lastoviza, 550 L. cavillone, 255 L. dieuzeidei and 40 T. lyra. These triglids were caught by three different methods: crustacean trawl, fish trawl and purse seine off the Algarve coast; all specimens sampled were part of the discards. Samples were obtained from depths ranging between 20 and 540 m, during 27 trips and 86 hauls. To the best knowledge of the authors, this study presents the first reference on weight–length relationships for four fish species from the Algarve coast (southern Portugal). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Applied Ichthyology Wiley

Abstract

Summary Gurnards or triglids are medium‐size marine bottom fishes that live in tropical and temperate seas. Four genera (Aspitrigla, Chelidonichthys, Lepidotrigla, Trigla) and eight species are found in the eastern Atlantic. In this study, we report the weight–length relationships for eight species, with 75 specimens of A. cuculus, 45 of C. obscurus, 84 C. gurnardus, 21 C. lucernus, 45 C. lastoviza, 550 L. cavillone, 255 L. dieuzeidei and 40 T. lyra. These triglids were caught by three different methods: crustacean trawl, fish trawl and purse seine off the Algarve coast; all specimens sampled were part of the discards. Samples were obtained from depths ranging between 20 and 540 m, during 27 trips and 86 hauls. To the best knowledge of the authors, this study presents the first reference on weight–length relationships for four fish species from the Algarve coast (southern Portugal).
