Résumé

Data on length and gonad-weight distribution, maturity and gonadosomatic index (GSI) of Antarctic toothfish Dissostichus mawsoni were collected from Subarea 88.1 on board of the longliner “Yantar” under Russian flag in the 2005/06 season.
Our supposition is that the predominant part of Antarctic toothfish population observed in SSRU –H, K, L in December 2005 – February 2006 will not be ready for participation in spawning of the current year. Ovaries of the most females weighed less than 2.0 kg; average GSI value of all the females examined did not exceed 2.0%.
