6. Histopathology of Antarctic krill (Euphausia superba) bearing black spots

   onboard a krill fishing vessel in the winter of 2003 and 2006 in the South Georgia region, the Antarctic ... Ocean, approximately 2-5% of sub-samples of 100 krill bore small black spots. The black spots were most ... often found on the cephalothorax of the body. Three bacteria were isolated from these black spots, and ... classified into either Psychrobacter or Pseudoalteromonas by the sequences of 16S rRNA genes. Histological ...
