[2] Bonham & Guberlet (1937) redescribed this species based on ten mature specimens from Sebastodes spp collected from Puget Sound, United States.

[3] Yamaguti redescribed Microcotyle sebastis based on two specimens from the gills of Sebastes schlegelii from Mutsu Bay, Japan.

[3] Yoon et al. studied the seasonality and the microhabitat of Microcotyle sebastis from the gills of farmed Sebastes schlegeli.

[6] Ayadi et al. suggested that the species of Microcotyle collected from Helicolenus dactylopterus from off Montenegro and identified as M. sebastis by Radujkovic & Euzet was probably a different species, based on extremely geographically distant localities (Pacific Ocean vs Mediterranean Sea), absence of detailed morphological evidences of identity, and absence of molecular information.

[7] Ayadi et al., suggested that species of Microcotyle from scorpaeniform fish on the Eastern side of the Pacific (USA coast) might be the same as M. sebastis (for which the type-locality is off Japan) and emphasised the need for a detailed morphological and molecular study of specimens from different localities and hosts.

[1] It was also reported from farms in Korea,[10][11][5][12][9] off California,[2] Puget Sound,[3] off Japan,[13] off Montenegro,[6] Southeast Atlantic,[14] and from the Pacific coast of North America.

[10] When Stanley & Lee investigated parasites of yellowtail rockfish, Sebastes flavidusfrom the Pacific coast of North America as potential biological tags for stock identification, they revealed that only Microcotyle sebastis showed a latitudinal cline with a prevalence increasing from 0- 10% in samples from central British Columbia, to 80 and 100% in those off and Oregon respectively.

[15] Microcotyle sebastis is a major parasitic disease agent for Sebastes schlegeli in Korea, responsible for a high mortality rate of juveniles in Summer.

[11] Kim et al. investigated the influence of the temperature on the rate of egg production and on the embryonic development of Microcotyle sebastis to determine the precise time of a second treatment.
