An ectoparasitic snail (Evalea tenuisculpta) infects red abalone (Haliotis rufescens) in northern California

We document the presence of the ectoparasitic fine-sculptured odostome snail (Evalea tenuisculpta) on red abalone (Haliotis rufescens) in northern California. Red abalone form the basis for an important recreational fishery north of San Francisco. We found that 82% of the red abalone examined from three sites (n=73) in Sonoma County had these small snail parasites. We document that the parasitic snails also infects northern abalone (H. kamtschatkana). Infected red abalone had an average of 12…

Impacts of the ectoparasitic snail Boonea impressa on growth of postset juvenile oysters
The objectives of this study were to examine the impact of these parasitic snails, when maintained at field densities, on the growth of oyster spat in a laboratory setting and to suggest that these ectoparasites could be especially damaging to recruiting cohorts of juvenile oysters.
Economic costs of protistan and metazoan parasites to global mariculture
This study examines the world's major marine and brackish water aquaculture production industries and provides estimates of the potential economic costs attributable to a range of key parasite pathogens using 498 specific events for the purposes of illustration and estimation of costs.
Foregut Development and Metamorphosis in a Pyramidellid Gastropod: Modularity and Constraint within a Complex Life Cycle
Examining foregut development through larval and metamorphic stages of O. tenuisculpta failed to find evidence that this modularity facilitated the extreme evolutionary remodeling of post-metamorphic feeding structures.


Odostomia as a pest of oysters and mussels
The Odostomia were lodged in small pockets inside the ventral margin of the shell of 2-year-old native brood oysters dredged from near Paglesham in the River Roach, Essex, and the pockets were formed as a consequence of the withdrawal of the mantle in response to the irritation caused by the proboscis of the parasite during feeding.
