Micro-organisms in the digestive tracts of Baltic fish
Investigations of the aerobic bacterial flora in the digestive tract of the following fish were carried out in 1995: European flounder (Platichhys flesus), burbot (Lota lota), Baltic herring (Clupea harengus membras), bullrout (Myoxocephalus scorpius), European pike-perch (Stizostedion lucioperca),...
