CCAMLR conservation measures: review of the numbering system
Abstract: Conservation measures are presently numbered using a combination of consecutive Arabic ... since 1984. However, the use of consecutive numbers does not provide information on topics covered by ... the measures, nor does it provide an implicit reference to the history of the measures. An improved ... numbering system is proposed which allows measures to be traced over the course of their history, contains ...

Biological features of the icefish Champsocephalus gunnari from commercial catches in Subarea 48.3 during the period from 8 December 1999 until 31 January 2000
western shelf of the South Georgia Island. Icefish 26-40 cm in length, with the average size of 30.3 cm ... made up the bulk of the catches. Length-frequency distribution was characterized by bimodality, with ... frequency peaks under 27-29 and 33 cm for fish aged 3 and 4 years. The by-catch of small size ... Champsocephalus gunnari (with the length of 24 cm and less) amounted to, on the average, 0.6% per a haul. The male ...

A revised estimate of short-term yield for the mackerel icefish (Champsocephalus gunnari) off Heard Island based on a trawl survey in 1998
Abstract: A random stratified trawl survey of Mackerel icefish in 2 populations (Plateau and ... Shell Bank) in the vicinity of Heard Island enabled a revised estimate of yield for the coming 2 seasons ... in 1999 and 2000. While the abundances of icefish are lower in 1998 than in 1997, the Age 3 and Age 4 ... cohorts are still sufficiently strong to provide for a yield greater than estimates of the long term ...

Hatching season and growth of Pleuragramma antarcticum larvae near the Antarctic peninsula in austral summer 1993/94
Abstract: Hatching season and larval growth of Pleuragramma antacticum in the water off Antarctic ... Peninsula were determined by the examination of growth increments in otoliths. The samples were collected by ... (54 inds. out of 77 fish larvae) in ichthyoplankton samples, and occurred mainly in cold water of the ... Weddell Sea. Body length of P. antacticum ranged from 12.0 to 67.3 mm. Otolith radii (R) ranged from 150 ...
