“…The degeneration of the host's gonads and suppression of the final stages of gametogenesis following parasitization by rhizocephalans was found [15,16]. According to our results [13], the roots of interna in the parasitic rhizocephalan P. polygenea spread over the hemocoel of the host crab reaching the internal organs of the crab. The gonads of the crab are fatally destroyed.…”

“…The studies that we carried out in the area of Vostok Marine Biology Station showed that the level of parasitization of the coastal crab Hemigrapsus sanguineus by the rhizocephalan P. polygenea varies significantly, but its maximum value may exceed 80% [13]; i.e., it reaches a level threatening the survival of the population. In different coastal areas of Japan, the proportion of crabs infested by this parasite ranges from 1.1 to 79.6% [19].…”

“…In these species numerous externae and even more numerous primordial externae develop in the budding interna, a phenomenon unique to crustaceans and the entire phylum Arthropoda, in general. The colonial organization of interna has been studied, in particular in the sacculinid Polyascus (Sacculina) polygenea (see [13,19]). …”

“…The rhizocephalans that infest small coastal decapods have been studied to a greater degree, in particular, the minute rhizocephalan Peltogaster reticulatus that parasitizes the coastal hermit crab Pagurus proximus and belongs, like B. callosus , to the family Peltogastridae. Also rather well studied is Polyascus (Sacculina) polygenea , a parasite of the coastal crab Hemigrapsus sanguineus [9,13,14,18,19]. These species of rhizocephalans and their hosts, decapods that have no commercial importance, but are easily available as a material for studies, could be considered as model objects for studies on rhizocephalans and their relationships with the hosts.…”

Rhizocephalan Barnacles—Parasites of Commercially Important Crabs and Other Decapods

Data are presented about the invasion level of commercially important crabs in the Sea of Okhotsk by rhizocephalan barnacles. Some general information concerning the structure, life cycle, and reproductive strategy of the parasitizing rhizocephalans and the effect on the Decapoda host. Practical recommendations have been proposed to decrease the infestation level in populations of commercially important crabs and to prevent parasitization of healthy populations.

“…In the Far Eastern seas of Russia, they still remain comparatively poorly studied. This paper is part of an integrated study [2,3,6,[13][14][15] on the widely distributed rhizocephalan barnacle Polyascus polygenea (Lützen et Takahashi, 1997) parasitizing the coastal crab Hemigrapsus sanguineus (De Haan, 1835).…”

Infestation Level of the Crab Hemigrapsus sanguineus by a Parasitic Crustacean Polyascus polygenea (Crustacea: Cirripedia) in Vostok Bay, Sea of Japan

We studied the infestation level of the coastal crab Hemigrapsus sanguineus by a cirripede barnacle Polyascus polygenea in Peter the Great Bay (Vostok Bay, Sea of Japan) in 1998-1999. It is shown that the externae of the parasite usually appear on the surface of the host's body at the time when the crab attains sexual maturity (at a carapace width of 14-15 mm). More often we encountered infested crabs of a medium size, with a carapace width of 25-29 mm. The level of crab invasion did not depend on the sex of the host. In the summer period the proportion of infested crabs in different habitats ranged from 7 to 84%. The greatest number of crabs bearing the externae of the parasite was registered in an area with a boulder-pebble surface and small surf waves.
