1. The diet of the Antarctic fur seal Arctocephalus gazella at Harmony Point, South Shetland Islands: evidence of opportunistic foraging on penguins?

   Abstract:  The diet of non-breeding male Antarctic fur seals Arctocephalus gazella was investigated at Harmony Point, Nelson Island, South Shetland Islands, by the analysis of 523 scats collected from January to March 2001 and 2002. The composition of the diet was diverse and both, pelagic and

2. Are penguins and seals in competition for Antarctic krill at South Georgia?

   Abstract:  The Antarctic fur seal (Arctocephalus gazella) and macaroni penguin (Eudyptes chrysolophus) are sympatric top predators that occur in the Southern Ocean around South Georgia where they are, respectively, the main mammal and bird consumers of Antarctic krill (Euphausia superba). In recent

3. World Fisheries Congress

   Abstract:  The Fourth World Fisheries Congress will be held in Vancouver, Canada 2-6 May 2004, with the theme “Reconciling Fisheries with Conservation” (See www.worldfisheries2004.org). There is an opportunity for CCAMLR scientists to participate in a session focussing on the Antarctic. It is

4. Detecting trends in the krill fishery

   Abstract:  The development of the krill fishery can be monitored and predicted using a number of different sources of information. Information on current catches and scientific information on the krill stocks is of limited value in plotting trends in the fishery at its current level. Predictions by

5. Conserving seabirds competing with fisheries for food – observations from southern Africa and Marion Island

   Abstract:  The paper describes moves towards accounting for the food requirements of some of southern Africa’s seabirds in management of pelagic fish stocks. It also considers moves towards establishing target populations for seabirds in South Africa, especially those of conservation concern. It

6. 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.

7. 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

8. 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

9. 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

10. 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
