SPATIAL PATTERNS IN MACKEREL ICEFISH DIET PROVIDES INSIGHTS INTO KRILL ABUNDANCE AND DISTRIBUTION
krill-dependent species was dominated by the hyperiid amphipod Themisto gaudichaudii (92 % IRI ... ) and was low in Antarctic krill (7 % IRI) compared with similar data for the same month in 2004-2006 ... . The results are consistent with other indicators of krill availability on the South Georgia shelf, which ... indicate that the 2008/09 season was a particularly poor one for krill. Comparison of frequency ...

Differentiated catchability of trawls as a method for a more precise estimate of density of krill swarms and its biomass
Abstract: Krill escapement in different parts of krill trawls and their differentiated ... catchability have been studied. It is shown that krill possesses behavioural peculiarities representing ... of fished krill swarms should be performed on the based of differentiated catchability of krill trawls ... . A mathematical model of krill trawling has been developed for estimating the above values. Author(s): V. Akishin ...

Krill fishery information
Abstract: This paper reviews information from krill fisheries operating in the CCAMLR Convention ... Area during the period July 1999 to June 2001. During that period, 14 vessels targeted krill in Area 48 ... during the 1999/2000 season (July 1999 to June 2000). A total of 104259 t of krill was caught, of which ... t from within Area 48 (subarea not specified). Between July and November 2000, 11 vessels targeted krill ...

Size and stage composition of age class 0 Antarctic krill (Euphausia superba) in the ice-water interface layer during winter/early spring
Abstract: The condition and survival of Antarctic krill (Euphausia superba) strongly depends ... on sea ice during winter. How krill utilize sea ice depends on several factors such as region ... and developmental stage. A comprehensive understanding of sea ice habitat use by krill, however, remains largely ... unknown. The aim of this study was to improve the understanding of the krill's interaction ...

Development of the krill stock in the elephant island region during the 1996/97 season
Abstract: During December 1996 the Elephant Island standard grid was surveyed for krill and salps ... . Krill and salps were present at almost all of the stations, other epipelagic zooplankton species were ... relatively scarce. Maximum krill density exceeded 7350 juvenile krill per 1000 m3. In general krill density ... was much higher than in previous years. The krill stock was dominated by length classes around 35 mm ...
