ANALYSIS OF THE STOMACH CONTENTS OF ANTARCTIC KRILL, EUPHAUSIA SUPERBA DANA
摘要
Diet components of Euphausia superba of 12 sexual maturity stages from the adjacent waters off the South Shetland Islands, Antarctica were analysed. The major points observed are summaried as follows: 135 taxa of nano-and microorganisms were found in stomach contents of Euphausia superba, of which, the diatoms make up 60% of the total species number. Planktonic nano-diatoms and nano-flagellates smaller than 20μm in diameter accounted for 85% of diet total number. The dominant species in the stomach contents were Nitzschia angulata f. minima, N. curta f, minima, N. curta,Chrysostomum sp., the mean cell number of these species was about 56.99 cells/ind., The stomach fullness increases gradually with the sexual mature of the krill.
