1. Comparisons in prey distribution between inshore and offshore foraging areas of chinstrap penguins and Antarctic fur seals at Seal Island

   Abstract:  At Seal Island breeding predators which incorporated an overnight period into their foraging trip such as Antarctic fur seals (Arctocephalus gazella) and overnight foraging chinstrap penguins (Pygoscelis antarctica) went beyond the inshore region and foraged in the slope/offshore region,

2. CPUE and recruitment indices calculated from log book data of Japanese krill fisheries

   Abstract:  CPUE and Recruitment indices during 1980 to 1995 were calculated based on the log book data from commercial krill trawlers. Long-term variation of monthly CPUE was shown but this trend might be the result of the alternation of operational strategy in relation to the product quality.

3. CPUE, net towing depth and body length of krill during the winter operation of Japanese krill fishery around South Georgia

   Abstract:  Monthly CPUEs during winter operation of Japanese krill trawlers around South Georgia were calculated. The range of CPUE values in 1991 season (poor year of krill) was comparable to the range of summer operation around Elephant Island and Livingston Island. Vertical distribution presumed

4. Preliminary results on by-catch of fishes caught by the fishery vessel Chiyo Maru No. 3 to the north of the South Shetland Islands (February to March, 1996)

   Abstract:  Investigations on by-catch of fishes captured during krill fishing by F/V Chiyo Maru No. 3 were made from 3 February to 6 March, 1996 to the north of the South Shetland Islands. Among 147 hauls examined, a total of 99 specimens belonging to 5 families and 14 species were captured as by

6. Proposal for an experimental crab fishery in Subarea 48.3

   Abstract:  An experimental management strategy is proposed for the Paralomis spinosissima fishery around South Georgia. The strategy is designed to answer specific, a priori questions about the population dynamics of P. spinosissima, and consists of three phases to be conducted over a period of two

7. Using production models to assess the stock of Paralomis spinosissima around South Georgia Island

   Abstract:  Four production models were fit to a time series of daily catch per unit effort (CPUE) data from the 1991/92 fishery for Paralomis spinosissima around South Georgia Island. The four models considered recruitment in different ways. Model 1 contained a linear recruitment function; Model 2

8. Variations in the diet composition and feeding intensity of mackerel icefish (Champsocephalus gunnari) at South Georgia (Antarctic)

   Abstract:  The diet composition and feeding intensity of mackerel icefish (Champsocephalus gunnari) around Shag Rocks and the mainland of South Georgia was analyzed from c. 8,700 stomachs collected in January/February 1985, January/February 1991 and January 1992. Main prey items were krill

9. On the taxonomy of the Lepidonotothen squamifrons group (Pisces, Perciformes, Notothenioidei)

   Abstract:  The Lepidonotothen squamifrons group has been described to be comprised of 3 species: L squamifrons (Günther, 1880). L kempi (Norman, 1937) and L macrophthalma (Norman, 1937). All 3 species closely resemble each other and morphological and meristic characters utilized to distinguish

10. Timescale of ovarian maturation in Notothenia coriiceps (Richardson); evidence for a prolonged adolescent phase

    Abstract:  Ovarian maturation in Notothenia coriiceps is known to include a period during which yolk deposition begins to take place. This 'adolescent' phase was thought originally to last for about one year. The results from a two year study at Signy Island indicate that this adolescent
