Abstract Four species of spionid polychaete infested shells of Pacific oysters Crassostrea gigas , in the Mahurangi Harbour, northern New Zealand: Polydora websteri, P. hoplura, Boccardia (Paraboccardia) acus , and B. (B.) chilensis . Three mudblister types, chiefly attributed to P. websteri , were characterised based on their morphology and position within the shell. Fortnightly washing of oysters for 5 and 11 months of growth had no effect on spionid infestations or oyster condition factors… Expand
Percentage of Infestation Level of Polydora cf. websteri Hartman, 1943 (Polychaeta: Spionidae) by Size Class of Crassostrea rhizhophorae (Guilding, 1828) on La Restinga Lagoon (Margarita Island, Venezuela).
TLDR
The infestation of mollusks bivalves with commercial importance by spionid polychaetes belonging, mainly, to genera Polydora, Dipolydora and Carazziella, has been recorded in many occasions and highly significative differences in the abundance of galleries between valves were found. Expand
Presence of spionid worms and other epibionts in Pacific oysters (Crassostrea gigas) cultured in Normandy, France
TLDR
Although it remains unclear how spionid mudworms affect summer mortality of oysters, it was demonstrated that they had a significant negative effect on host growth. Expand
Confirmation of the shell-boring oyster parasite Polydora websteri (Polychaeta: Spionidae) in Washington State, USA
TLDR
Data show that Polydora websteri are present in the mud blisters from oysters grown in Puget Sound, constituting the first confirmed record of this species in Washington State, and could threaten the sustainability of oyster aquaculture in Washington, which currently produces more farmed bivalves than any other US state. Expand
Infestation of the surf clam Mesodesma donacium by the spionid polychaete Polydora bioccipitalis
TLDR
The infestation could play a key role in explaining mass mortality of northern populations during El Nino events, given the latitudinal differences in PI and the fact that infestation ability could be enhanced by increased temperature and facilitated in stressed clams. Expand
Spread of the invasive shell-boring annelid Polydora websteri (Polychaeta, Spionidae) into naturalised oyster reefs in the European Wadden Sea
With globally growing aquaculture activities, the co-introduction of parasites alongside large-scale movements of commercial species poses an increasing risk for marine ecosystems. Here, we presentExpand
Comparison and history of Polydora websteri and P. haswelli (Polychaeta: Spionidae) as mud-blister worms in New Zealand shellfish
Abstract Shells of commercially valued bivalves in New Zealand, Crassostrea gigas, Perna canaliculus and Pecten novaezelandiae, are damaged by blister-causing Polydora polychaete species known to beExpand
Polydorid species (Polychaeta: Spionidae) associated with commercially important mollusk shells in Korean waters
TLDR
The polydorid species from the viewpoint of aquaculture and unintentional transportation of alien species which have been introduced with commercially important host shells are discussed. Expand
Polydorid species (Polychaeta: Spionidae) in south-western Australian waters with special reference to Polydora uncinata and Boccardia knoxi
TLDR
This study suggests that further monitoring of polydorid species is needed not only from the viewpoint of marine biology but also to survey the risk invasive species pose to commercially important molluscs in this region and worldwide. Expand
Parasitas em ostras de cultivo (Crassostrea rhizophorae e Crassostrea gigas) da Ponta do Sambaqui, Florianópolis, SC
TLDR
Over a 10-month period, cultured oysters from Ponta do Sambaqui, Florianopolis, Santa Catarina State were evaluated microscopically and histologically for parasite infection and found that C. rhizophorae could not be associated with parasite infection. Expand
Polydorid species (Polychaeta, Spionidae) associated with commercially important mollusk shells from eastern China
TLDR
Three species of the genus Polydora ( P. onagawaensis, P. brevipalpa, and P. websteri) are here described for the first time from mollusk shells from Chinese waters and this is the first record of P. BrevipalPA extracted from shells other than P. yessoensis. Expand

TLDR
Evidence or reports of infestation throughout the entire range of distribution of the American oyster, 0. Expand
Systematics and biology of polydorid species (Polychaeta: Spionidae) from Wellington Harbour
TLDR
Fourteen species of genera Boccardia, Polydora, and Pseudopolydora are described from Wellington Harbour, including three new species and two new records from New Zealand, and the distinctions between the polydorid genera are discussed. Expand
Influences of temperature, salinity and available food upon suspended culture of the Pacific oyster, Crassostrea gigas: II. Condition index and survival
TLDR
Dry meat weight:dry shell weight ratio was a more suitable index for assessing the condition of oysters provided available food and water temperature were the principal factors affecting growth. Expand
Influences of temperature, salinity and available food upon suspended culture of the Pacific oyster, Crassostrea gigas: I. Absolute and allometric growth
TLDR
It is suggested that under prolonged periods of low food supply, oysters preferentially partition energy resources toward increasing shell weight and thickness over body tissue weight, which may be inhibited under conditions of low salinity. Expand
The Mud-Blister Worm, Polydora, in Canadian Oysters
TLDR
Polydora ciliata causes mud blisters on the shells of oysters (Ostrea virginica) in deep water, in the intertidal zone and in floating trays in many important producing areas. Expand
Resuspension and growth ofOstrea edulis: A field experiment
TLDR
It is postulated that sand bottoms may provide more suitable resuspension environments than mud due to lower suspended loads over coarse sediments, and the relationship of oyster growth to gross changes in sediment chlorophyll showed a similar parabolic trend. Expand
Recent Advances in Oyster Biology
TLDR
All students of invertebrate biology and all those interested in the problems of marine ecology may benefit by a review of recent oyster papers, for this may draw their attention to possible gaps in the knowledge of the biology of other invertebrates, and to the influence of thus far poorly understood or even unknown ecological factors. Expand
The use of physiological condition indices in marine bivalve aquaculture
TLDR
The dynamic indices reviewed are based on production estimates, and hence reflect physiological changes over specified time intervals, and only net growth efficiency is recommended for use in bivalve aquaculture, and it is applicable to all life stages. Expand
