Biomass and length distribution for Roughhead grenadier, Thorny skate and White hake from the surveys conducted by Spain in NAFO 3NO
Data for Roughhead grenadier (Macrourus berglax), Thorny skate (Amblyraja radiata) and White hake (Urophycis tenuis) from Spanish Spring survey are presented. The abundance and biomass were estimated for the period 1997-2009 for Roughhead grenadier and Thorny skate, and 2001-2009 for White hake. The...
