“…Salinity, as one of the basic indicators of water environment, usually varies with climate changes or human activities, thus affecting the survival of aquatic animals (Kinne, 1964; Lettieri et al, 2019; McNeil & Sasse, 2016). As an important member of aquatic animals, bivalves are affected by salinity in many aspects (Hosoi et al, 2010; Lettieri, Maione, et al, 2019; Madrones‐Ladja, 2002; Taylor et al, 2004; Verween et al, 2007). Oyster is a typical euryhaline bivalve (Xu et al, 2011), and the researches on the effects of salinity on oysters are attracting attention, which mainly focus on gamete quality (Qin et al, 2018), embryonic development (Dos Santos & Nascimento, 1985), fertilization and hatching (Han & Li, 2018), larval growth and survival (Kinne, 1964; Nell & Holliday, 1988), and growth and survival of juvenile (Rybovich, Peyre, Hall, & Peyre, 2016).…”
