dc.description.abstract | The trophic niches of Arctic charr and brown trout differ when the species occur in
sympatry
. Their
trophically transmitted parasit
es are expected to reflect these
differences.
Here
, we investigate how the infections
of
Diphyllobothrium dendriticum
and
Diphyllobothrium ditremum
differ between
charr and trout. These tapeworms use
copepods as their first intermediate hos
ts and fish can become infected
as second
intermediate hosts
by consuming
either infected copepods or infected
fish
. We
examined 767 charr and 368
trout for
Diphyllobothrium
plerocercoids
in a subarctic
lake.
The
prevalence of
D. ditremum
was higher in charr (61.5
%) than
in trout
, (39.5
%), but the prevalence of
D. dendriticum
was higher in trout (31.2 %) than in charr
(19.3 %).
Diphyllobothrium
spp. intensities were elevated in trout compared to charr,
particularly for
D. dendriticum
. Large fish with massive parasite bur
dens
were
responsible for the high
Diphyllobothrium
spp.
loads
in trout.
We hypothesize
that
fish
prey may be the most important
source for the
Diphyllobothrium
spp.
infection
s
in trout, whereas charr predominantly acquire
Diphyllobothrium
spp.
by feeding
on
copepods
. Our findings support previous suggestions, that
the
ability to establish in a
second piscine host is greater for
D. dendriticum
than
for
D. ditremum
