Description
Summary:This working document presents the results of the significant cephalopods in the Spanish Ground Fish Survey on the Porcupine bank (SPPGFS) from 2001 to 2011. The species more abundant in biomass terms in these surveys are curled octopus (Eledone cirrhosa), European flying squid (Todarodes sagittatus), seven-arm octopus (Haliphron atlanticus), Northern European squid (Loligo forbesi), globose octopus (Bathypolypus sponsalis), lesser flying squid (Todaropsis eblanae), broadtail shortfin squid (Illex coindetti) and stout bobtail squid (Rossia macrosoma). Biomass, distribution and length ranges were analysed. Most of the species occur in the shallower areas, except T. sagittatus, H. atlanticus and B. sponsalis that were mainly found in the deep strata.
