“…Consequently, the S. marmoratus population may have a high capacity to adapt to the environment (Xue, Zhang, Li, & Liu, ). Previous research has shown that a population with small effective population size (Ne) will cause genetic diversity to be depleted, will increase random drift and threaten the survival and evolution of the population (Anderson, Cason, & Chavez, ; Frankham, Briscoe, & Ballou, ). Unlike other marine species, such as Fenneropenaeus chinensis and Portunus trituberculatus, which have suffered too much human interference (for example, intensive catching and stock enhancement) in the northwestern Pacific (Liu et al, ; Song, Li, Zhang, & Gao, ), the S. marmoratus population has a large Ne (67.0 ‐∞), low genetic relatedness (<0.01) and a low level of inbreeding (<0.12).…”
