1. An exploratory analysis of skate speciation using DNA identification techniques

   Abstract:  Two regions of the mitochondrial DNA, part of the cytochrome b gene and the control region, were sequenced in specimens of Antarctic skates from the Ross Sea (Pacific Ocean sector), the Australian Antarctic Territory (Indian Ocean sector), and around Elephant Island and the South

2. Geographical differences in the condition, reproductive development, sex ratio and length distribution in Antarctic toothfish (Dissostichus mawsoni) from the Ross Sea, Antarctica (CCAMLR Statistical Subarea 88.1)

   Abstract:  A number of morphological and reproductive measurements made on Antarctic toothfish Dissostichus mawsoni over the four summer seasons from 2000-01 to 2003-04 aboard the autoliner San Aotea II have been analysed. Summer seasons are defined here as the period from mid December to the

3. Age and growth of the Antarctic skate (Amblyraja georgiana) in the Ross Sea

   Abstract:  X-rays of vertebral half-centra, and X-rays and transmitted white light examination of caudal thorns, were used to estimate the ages of Amblyraja georgiana from the Ross Sea. Caudal thorns viewed with transmitted white light provided the clearest growth bands, but reading precision was

4. Report on the identification of fish eggs and larvae taken in the Ross Sea, Subarea 88.1, autumn/winter 2003

   Abstract:  Icthyoplankton sampling was carried out by the New Zealand bottom longliner Avro Chieftain in the Ross Sea Sub Area 88.1 in the 2002-03 fishing year. Four direct haul samples were taken with a UNESCO WP2 net to a maximum depth of 1620 m in areas where mature D. mawsoni had been observed.

5. Stomach contents of the Antarctic toothfish (Dissostichus mawsoni) from the western Ross Sea, Antarctica

   Abstract:  The stomach contents of 496 Antarctic toothfish (Dissostichus mawsoni) captured by bottom longline in the western Ross Sea during the 2003 summer fishing (from Dec 2002 to Jun 2003) season were analysed. Fish sampled were caught in 770-1890 m depths and ranged between 72–212 cm in total

6. Genetic analysis of Antarctic toothfish samples from the Southern Ocean to explore potential stock boundaries

   Abstract:  Two molecular methods, mitochondrial DNA and introns, were used to determine genetic relationships among Antarctic toothfish, Dissostichus mawsoni, samples from three CCAMLR areas 48.1, 88.1, and 58.4.2. D. mawsoni appeared to be characterized by low diversity; no genetic variation was

7. Information on the spawning of Dissostichus mawsoni from Subareas 88.1 and 88.2 in the 2003/04 season

   Abstract:  Data on maturity, gonadosomatic index (GSI) and length weight of Antarctic Toothfish Dissostichus mawsoni were collected from Sub areas 88.1 and 88.2 in the 2002-2003 season by the New Zealand bottom longline vessels Janas, Avro Chieftain and San Aotea II operating in the Exploratory
