    Abstract

    Data on maturity, gonadosomatic index (GSI) and length weight of Antarctic toothfish Dissostichus mawsoni were collected from Sub-area 88.1 in the 2002-2003 season by the New Zealand bottom longline vessels Janas, Avro Chieftain and San Aotea II operating in the Exploratory Fishery. The first spawning fish were found in April, a month earlier than in the previous season.
