(Schrenck, 1867), which is also
known as the blood clam, is one of the widely distrib
uted bivalves in the Pacific basin . Active coastal
fishing for this species in the Russian Far East has been
conducted since 1996 . The processed blood clam
in the form of preserved seafood is exported to Japan.
A blood clam shell contains more than 35% easily
absorbable calcium, as well as magnesium, potassium,
phosphorus, sodium, iron, iodine, molybdenum,
cobalt, selenium, etc. .
The study of the filamentous fungi that colonize
the internal organs of the blood clam forms the basis
for further investigations into the pattern of interac
tions in the “molluscs–microorganism” biological
system. Moreover, many species of filamentous fungi,
as opportunistic organisms, cause mycoses and myc
otoxicoses of aquatic animals. Many strains of fila
mentous fungi produce mycotoxins, which can induce
mycotoxicoses in animals and humans [4, 16].
The goal of the present work was to study the myco
from various parts of the
Peter the Great Bay in the Sea of Japan.
MATERIALS AND METHODS
Blood clam individuals that were collected from
various parts of Peter the Great Bay in 2008–2012
served as the material for these mycological studies.
The molluscs were collected over the area of Amurskii
Bay, which is exposed to the influence of industrial and
household wastewaters from the city of Vladivostok
, and in the relatively clean Vostok Bay  (ten indi
viduals from each site).
The methods of the mycological study of the mol
luscs consisted in inoculation of solid culture media
with prepared specimens of internal organs and pieces
of shell [5, 10]. To isolate and cultivate the fungi, we
used the universal Sabouraud’s agar medium, which is
based on filtered and diluted (75%) seawater, pH 7.5–
7.8 . To identify the isolated fungi, the commonly
accepted keys were used [4, 6]. The modern taxo
nomic status of the fungi was verified to be in accord
with the Index Fungorum international database for
The strains of filamentous fungi that were isolated
were deposited in the Collection of
Pure Cultures of Marine Fungi at the Zhirmunsky
Institute of Marine Biology (IMB) at the Far Eastern
Branch of the Russian Academy of Sciences (FEB
RESULTS AND DISCUSSION
A total of six species of filamentous fungi belonging
to five genera, viz.,
(1), were isolated from the shell surface
and internal organs of blood clams (see the table).
Here we should note the small number of species of fil
amentous fungi that were found in this clam from the
Mycobiota of the Bivalve Mollusk

—A mycological study of the bivalve mollusc
(Schrenck, 1867) (Bivalvia) from
the Peter the Great Bay of the Sea of Japan has been conducted for the first time. The taxonomic composition
of the filamentous fungi that are associated with
includes the following six species, which are
found in the internal organs and on the shell surface:
