“…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.…”

“…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.…”

The Gray mussel Crenomytilus grayanus occurs in high density in the shallow rocky subtidal zone on the east coast of Korea, where the mussel dominates the shallow subtidal benthic community. In this study, we first examined the annual gametogenesis and temporal changes in the tissue composition, which provides crucial information to the management of the mussel on the east coast. Based on histological analysis, oogenesis and spermatogenesis commenced in September, as the small oogonia (16.67 ± 4.87 µm in diameter) and spermatogonia developed on the follicle walls, respectively. In March, the mature oocytes (46.55 ± 9.91 µm in diameter) and spermatozoa dominated the follicle. During May and June, most of the males and females spawned when the surface seawater temperature (SST) increased from 15.5 to 22.3 °C. The total carbohydrate level in the tissue increased dramatically from April to May, which coincided with the chlorophyll-a maximum occurring in April. Condition index, a ratio of tissue weight to shell weight, also increased from February to May and then declined in June, suggesting that most mussels released the gametes through spawning during these months. Our data suggest that C. grayanus is a spring spawner, and the onset of gametogenesis and subsequent spawning is closely linked to the seasonal changes in the water temperature and food availability in the water column.
