1. Soviet krill fishery in the Atlantic sector of Antarctic in 1977–1992: Part II – CPUE changes and fleet displacement

   Abstract:  CPUE values of the Soviet krill fishery in 1977-1992 in subareas 48.1, 48.2 and 48.3 are standardized by vessel types, regional fishery associations, months, years and subareas. The causes which determine CPUE variability are revealed. Author(s):  F.F. Litvinov, P.S. Gasiukov, A.Z.

2. Fishing patterns of Japanese krill trawlers

   Abstract:  Log book data from Japanese Krill Trawlers were used to characterize their fishing strategies, especially focusing on their movement in time and space. The operations were grouped into ‘operation units’ which consists from a group of repeated operations within certain searching ranges

3. MaxEnt reconstructions of krill distribution and estimates of krill density from acoustic surveys at South Georgia 1996–2000

   Abstract:  We present Maximum Entropy (MaxEnt) reconstructions of krill distribution and estimates of mean krill density within two survey boxes of dimensions 80 km x 100 km to the north east and north west of South Georgia. The reconstructions are generated from acoustic line transect survey data

4. The three-frequency method for classifying the species and assessing the size of two euphausiids (Euphausia superba and Euphausia crystallorophias)

   Abstract:  In this paper an acoustic method for identifying two euphausiid species and estimating their length is described. The approach is in fact an outgrowth from both the fluid sphere and Bayes rule methodologies. This paper explores applications of the multi-frequency method using data from

5. Relationships between distribution of two euphausiid species and oceanographic characteristics in the Ross Sea (January–February 2000)

   Abstract:  During austral summer (January 21st to February 5th) 2000 an oceanographic cruise, devoted to study two krill species (Euphausia superba and Euphausia crystallorophias), was carried out in the Ross Sea area. Activities included acoustic, fishery and physical measurements. More than 2370

6. Seasonal variation in acoustic estimates of krill density at South Georgia during 2001/2002

   Abstract:  Four separate acoustic surveys of Antarctic krill (Euphausia superba) were conducted around South Georgia in the 2001/2002 season: one in November 2001 (early); two during January 2002 (middle), and one in May 2002 (late). The surveys were the second in a five-year series of observations

7. Defining fishing grounds in the Scotia Sea

   Abstract:  This paper provides a method for delineating krill fishing grounds in Area 48 based on commercial catch data for the region held in the CCAMLR database. It also summarises available information on krill distribution and abundance and movement for the region, which can be used to help

8. Defining predator foraging ranges, illustrated using Adélie penguin foraging tracks from Mawson coast

   Abstract:  One step toward defining small-scale management units is to determine the areas most likely to be foraged by predators from one year to the next, i.e. what is a predator’s feeding range taking into account interannual variation in foraging locations? This paper considers the issues to be

9. Deaths of Adélie penguins at Mawson November–December 2001 investigated

   Abstract:  Over 120 adult Adélie penguins were found dead in unusual circumstances on Welch Island near Mawson between 23 November and 4 December, 2001. It is concluded the most likely cause of death was severe injury from being crushed by ice at the ice land interface. Circumstance surrounding the

10. Comparison between the CCAMLR-2000 and KY 1988 surveys on environmental variability of krill in the Scotia Sea, Antarctica

    Abstract:  We assessed the environmental variability of Antarctic krill (Euphausia superba) distribution with comparison between the CCAMLR 2000 Survey and similar scale datasets partially by the Japanese R/V Kaiyo Maru Survey in the 1987/88 austral summer season in the Scotia Sea. There were
