Comparison with the Hvannasund and
the Vestmanna schools
Tissue samples of the three schools were
distributed to B. Amos, University of Cam-
bridge and to Andersen, so that genetical
comparison of the three schools could be
performed by means of DNA analysis and
electrophoretic markers respectively. Re-
sults of these analysis have not yet been
communicated.
There were differences in stomach con-
tents between the Tórshavn and the
Vestmanna schools. One of the stomachs
from Vestmanna was empty and the four
others contained, like the stomachs from
Tórshavn, only hard remains of prey.
However, three stomachs contained only
hard remains of fish, mostly from Micro-
mesistius poutassou, while only one con-
tained cephalopod beaks from a different
species, Gonatus sp..
The stomachs of the five mature males
from Vestmanna were also infested by the
