We found metacercariae eye vitreous humor rudd, Scardinius erythrophthalmus; bleak, Alburnus alburnus; and roach, Rutilus rutilus, Karelia (Russia) identified them as numericum based on combination morphological ecological data. Previously, D. was thought ...
We compared the repeatability, reproducibility (intra- and inter-measurer similarity), separative power and subjectivity (measurer effect on results) of four morphometric methods frequently used in ichthyological research, the "traditional" caliper-based (TRA) and truss-network (TRU) distance methods and two geometric methods that compare landmark coordinates on the body (GMB) and scales (GMS)....

We collected and artificially digested 85 roach halves originating from the south-eastern coast of Finland, and found trematode metacercariae in 98.8% of the samples.
