Galeus melastomus, Raja montagui, Etmopterus spinaxand Leucoraja 
naevus.  Biomass,  distribution  and  length  ranges  were  analysed.  A 
marked  increase  in  biomass  of  almost  all  species  with  regard  to 
previous  years  was  found,  especially  in  S.  canicula and  R.  clavata  in 
IXa Division. L. naevus and G. melastomus were the only species which 
decreased in VIIIc Divisio

Results on main elasmobranch species captured in the bottom trawl surveys on the Northern Spanish Shelf

This working document presents the results on the significant elasmobranch 
fish species captured in the Spanish Groundfish Survey on Northern Spanish 
shelf  in  2011.  The  main  species  in  biomass  terms  in this  survey,  in 
decreasing  abundance  order,  were  Scyliorhinus  canicula,  Galeus 
melastomus and Raja clavata (altogether made up a 91% out of the total of 
elasmobranches fish species). With less abundance also Leucoraja naevus, 
Raja montagui and Etmopterus spinax were recorded (7% out of the total of 
elasmobranches fish species), followed by other less important in biomass 
terms  (2%  out  of  the  total  of  elasmobranches  fish  species).  Biomass, 
geographic  distribution  and  length  ranges  were  analysed.  Galeus 
melastomus  and  Etmopterus  spinax  dwell  deeper  areas than  Scyliorhinus 
canicula, Raja clavata, Leucoraja naevus and Raja montagui do

This  working  document  presents  the  results  on  some  significant 
elasmobranch  fish  species  in  the  Spanish  Groundfish Survey  on  Northern 
Spanish shelf in 2010. The main species in biomass terms in this survey are 
Scyliorhinus canicula, Galeus spp., Etmopterus spinax, Raja clavata, Raja 
montagui and Leucoraja naevus in decreasing abundance order. Biomass, 
distribution  and  length  ranges  were  analysed.  Galeus  spp.  and  E.  spinax 
occupied deeper areas than S. canicula and R. montagui was not distributed 
as deep as the other two rays
