predation, catch rates of krill in plankton nets and the proportion of primary production 

 that is converted into krill. However, there are no direct or accurate data on the magnitude 

 of either the standing stock or annual production of Euphausia superba. (Although E. superba 

 is often considered to be synonymous with krill, and indeed is the dominant species, 

 a number of other euphausiids should also be included under the term, and these are 

 particularly important at the ice edge.)

The estimated high productivity of krill has led some nations to engage m serious efforts to 

 test its possibilities as a food source for animal and human populations. The USSR is reported 

 to have taken some 20 000 tons in 1974, while Japan collected about 650 tons. Results of 

 biochemical analyses and nutritional studies have encouraged commercial utilization and other 

 nations-the Federal Republic of Germany, Poland, Norway, the United Kingdom-are also
