We present preliminary results on age and growth of Dissostichus mawsoni for thesecond season (2013/14) of the Spanish research fishing in the 58.4.1 Divisionobtained for growth rings on otolith readings. It is included the age-length key andgrowth parameters estimates by sex. Growth parameters obtained using length-agepair values are: L∞: 175.7, k: 0.1078 and t0: 1.528 for females; L∞: 150.3, k: 0.1491and t0: 1.809 for males; and L∞: 169.8, k: 0.1087 and t0: 1.168 all combined. Theseresults are very similar to those reported previously for the first season (2012/13)although they differ slightly with the values used in the Ross sea assessment formales.
