   Abstract:  Chaenocephalus aceratus and Pseudochaenichthys georgianus have been exploited in Subarea 48.3 since 1977 but have never been fully assessed by the Working Group on Fish Stock Assessment because of a lack of reliable biological and catch data. This paper attempts to reconstruct the

4. Pilot study on electrophoretic variation and stock structure in the mackerel icefish, Champsocephalus gunnari, South Georgia waters

   Abstract:  The use of allozymes as a tool in stock structure analysis was examined in the commercially-exploited mackerel icefish, Champsocephalus gunnari, together with a preliminary assessment of stock separation among samples in South Georgia waters. Four samples (116 individuals) of icefish

7. A re-assessment of the stock of Notothenia gibberifrons in the South Orkney Islands (Statistical Subarea 48.2)

   Abstract:  Based on a tentative adjustment of catches of Notothenia gibberifrons previously reported as ‘Pisces nei’ an attempt is made to reconstruct the fishery on that species between 1977/78 and 1985/86. Stock size until the mid 1980s seemed to be more reduced than previously assumed. The

8. A re-analysis of the Kerguelen Shelf and Skiff Bank stocks of Champsocephalus gunnari

   Abstract:  Catches of Champsocephalus gunnari from the Kerguelen Shelf and Skiff Bank stocks were re-calculated from those used by the Working Group on Fish Stock Assessment in 1989 using length-frequency data for the years 1981 to 1990. Cohort analysis yielded a Stock Biomass of 22 711 tonnes in

9. Feeding and food intake of Electrona carlsbergi (Tåning) (Myctophidae)

   Abstract:  In the summer-autumn period E. carlsbergi fed mainly on copepods. Daily food intake measured using various methods ranged from 3.7 to 5.6 % of fish body weight. The amount of food consumed by E. carlsbergi during the year in the southern regions of the Antarctic Convergence is about 15

10. Biomass of myctophids in the Atlantic sector of the Southern Ocean as estimated by acoustic surveys

    Abstract:  Acoustic surveys carried out in summer and autumn periods of 1987-1989 estimated the biomass of myctophids in the Atlantic sector of the Southern Ocean over the region between 48° and 56°S and from 8° to 48W at about 1.7 mill.t. Over the larger part of the surveyed area the fish were
