Morphology of adult Phyllodistomurn umblae (Fabricius) (Platyhelminthes, Gorgoderidae): the effect of preparation, killing and fixation procedures
Twenty two different handling techniques for determining the morphology of Phyllodislormum umblae recovered from the Arctic char, Salvelinus alpinus , in Norway are examined. In some procedurcs both hot and cold fixation were used. Examples of different methods are illustrated by photographs. In add...
