Update of ongoing work on age and growth of Antarctic toothfish (Dissostichus mawsoni) from Division 58.4.1 by Spain
We present preliminary results on age and growth of Dissostichus mawsoni for the third season (2015/16) of the Spanish research fishing in the 58.4.1 Division obtained for growth rings on otolith readings. It is included the growth parameters estimates by sex. Growth parameters obtained using length...
