Records of deep water chondrichthyan fish caught on long-line in the Rockall Trough
A number of chondrichthyan fish species were caught on long-line in the Rockall Trough (north-east Atlantic) in 1997, which are first records for this area; Raja hyperborea, Raja kukujevi and Raja fullonica . The occurrence of R. hyperborea , usually found in colder boreal waters appears to be tempe...
