Distribution, abundance, and growth of anglerfish (Lophius piscatorius) on the Porcupine Bank (west of Ireland).

This manuscript presents the first results on abundance and distribution of white anglerfish (Lophius piscatorius) from a series of groundfish surveys carried out on the Porcupine Bank. White anglerfish were caught in all trawlable areas, recruits and juveniles mainly from the shallower parts of the...
