Contribution to the knowledge of the marine bivalve mollusk fauna of Gangwon Province, Korea

Report on the Annual Gametogenesis and Tissue Biochemical Composition in the Gray mussel, Crenomytilus grayanus (Dunker 1853) in the Subtidal Rocky Bottom on the East Coast of Korea

“…Endemic to the coastal East/Japan Sea, C. grayanus has a wide distribution from the Sea of Okhotsk, Kurils, the Peter the Great Bay, and the coastal East/Japan Sea (Min et al 2004;Galysheva 2008;Belcheva et al 2011;Selin and Dulenina 2012;Lutaenko and Noseworthy 2019). Despite their popularity, no studies have investigated the annual gametogenesis of C. grayanus in the endemic area.…”

“…The reproductive pattern of C. grayanus obtained in this study can provide crucial information about the appropriate time for natural spat collection during the post-spawning period and the sustainable fishery of the mussels in the study area. A limited number of studies have reported the annual gametogenesis of the mussels occurring on the coastal rocky intertidal and subtidal of the east coast of Korea, where several mussels species, including C. grayanus, M. galloprovincialis, M. trossulus, and M. coruscus have been reported (Min et al 2004;Lutaenko and Noseworthy 2019). Yang et al (2021) first reported the annual gametogenesis of the mussel M. coruscus occurring in the shallow subtidal in Ulleungdo Island off the east coast, which is somewhat comparable to the annual reproductive cycle of C. grayanus.…”

“…Accordingly, understanding the annual gametogenesis is crucial to forecast the spawning period and subsequent spat harvest from the environment (Ventilla 1984;Arakawa 1990;Ngo et al 2006;Uddin et al 2007Uddin et al , 2012Mondol et al 2016). Unlike the south coast, the rocky shallow east coast of Korea is dominated by the Gray mussel Crenomytilus grayanus, which occurs at a high density on a shallow subtidal rocky substrate (Galysheva 2008;Lutaenko and Noseworthy 2019;Selin and Dulenina 2012). The Gray mussel has a high potential as an aquaculture species on the east coast due to the larger size and high nutritional values.…”

Effect of Extreme Heatwaves on the Mortality and Cellular Immune Responses of Purplish Bifurcate Mussel Mytilisepta virgata (Wiegmann, 1837) (=Septifer virgatus) in Indoor Mesocosm Experiments

“…Intertidal mussels are widely used as sentinel species in coastal environmental monitoring because they are ubiquitous fauna, able to provide a spectrum of responses to environmental stress, live a sedentary life that may explain the spatiotemporal changes in their habitat (Goldberg, 1975;Farrington et al, 2016;Beyer et al, 2017). The purplish bifurcate mussel Mytilisepta virgata (= Septifer virgatus) is distributed widely in the upper rocky intertidal zone of the northwest Pacific region from Hong Kong to northern Japan (Benard et al, 1993;Iwasaki, 1995;Kawai and Tookeshi, 2004;Lutaenko and Noseworthy, 2019;Lee et al, 2020). Similar to other mussels, the purplish bifurcate mussel has been used as a sentinel species in environmental monitoring studies due to its abundance and high tolerance to environmental stressors (Liu and Morton, 1994;Wang and Dei, 1999;Blackmore, 2001;Han et al, 2020).…”
