1. Discussion on recent results from an integrated assessment of Antarctic krill (Euphausia superba) in Subarea 48.1

   from three of the models provide a robust picture of changes in the krill population.  An annual model ... surveys estimated similar absolute biomasses and changes in biomass.  A seasonal model estimated similar ... changes in biomass but lower absolute biomasses than the two annual models.  A monthly model estimated ... different changes in biomass but predicted absolute biomasses that were similar to those from the seasonal ...

2. Precision of growth band determination from eyestalk sections of Antarctic krill (Euphausia superba) preserved in formalin

   feedback management of krill fisheries. Samples stored in 70% ethanol provide an opportunity to detect the ... growth bands of eyestalk sections. Moreover, information derived from samples preserved in formalin will ... common in previous decades. Out of 162 Antarctic krill individuals preserved in 5% formalin, the growth ... the growth bands in the eyestalk was analyzed. Three main parameters, including exact percent ...

5. USING ECOSYSTEM STRUCTURE TO IDENTIFY FINER-SCALE SSMUS FOR OCEANIC AREAS IN SUBAREAS 48.1 TO 48.3

   Abstract:  One of the main issues in the management of the krill fishery is finding a spatial ... initial framework of small scale management units (SSMUs) in subareas 48.1 to 48.4 based on the spatial ... consumption of krill by predators and 10% of the cumulative total fishery catch in the three subareas (48.1 to ... 48.3) where the fishery operates. There is ample evidence of structure in oceanic areas from both ...

9. Analysis of krill trawling positions in the area north of the South Shetland Islands (Antarctic Peninsula area) from 1980/81 to 1998/99

   Abstract:  Positions of commercial krill operation for 1980/81 season to 1998/99 season in the ... latitudes where operations were undertaken. Operations tended take place in the north in early 1980s, but ... from mid-1980 onwards, they tended to happen in the south, with exceptions of 1994/95 and 1995/96 ... seasons. Predicted latitudes of operation significantly correlated with Salp densities in the Elephant ...
