Biological information on a rare pelagic fish, black ruff <scp> Centrolophus niger </scp>, caught in Icelandic waters: Distribution, feeding, and otoliths
Abstract Black ruff ( Centrolophus niger ) is a rare and poorly studied species found in both the Atlantic and Pacific Oceans and also in the Mediterranean Sea. It is sporadically caught south of Iceland during the annual International Ecosystem Summer Survey of the Nordic Seas. In total, 43 specime...

It is sporadically caught south of Iceland during the annual International Ecosystem Summer Survey of the Nordic Seas. In total, 43 specimens were caught from 2009 to 2021, of which 41 specimens were caught during 2017–2021.
