“…We first defined the range limits of historical oyster reef extent across the PRD based on the furthest eastern to western points of past oyster observations, that is from Tsing Yi in Hong Kong to Taishan (Sunning) in western PRD. Since the maximum known subtidal water depth limit of the locally found Magallana species (M. gigas, M. ariakensis and M. hongkongensis) in PRD range to 10-13 m (Meng et al 2018;Quan et al 2013;Lam & Morton 2004), we infer the habitable areas for historical oyster reef would have existed from the intertidal (0 m) to subtidal area up to 12 m between Tsing Yi in Hong Kong to Sunning in western PRD. This 12 m lower depth boundary also coincides with the salinity regime up to ~30 psu in the PRD (Zhi et al, 2022), which is a threshold that is tolerable for M. gigas, M. ariakensis and M. hongkongensis (Huo et al, 2014;Qin et al, 2020;Zhao et al, 2012).…”

Degradation of marine ecosystems by human activities is a global problem, with only recent recognition that exploitation of ecosystems over millennia can result in their functional extinction and loss from human memory. To reconstruct the historical distribution of oyster reefs in China, and the context behind loss, we extracted information from archaeological records and historical documents (pre-modern Chinese literature, administration reports, art, maps, newspapers) spanning ~7600 years, then constrained records with past coastlines and habitable environmental conditions. Oyster reefs were extensively distributed along >750 km of coastline in the Pearl River Delta, and their exploitation underpinned the region's development into China's first economic hub in the 6th century. Millennial-scale overexploitation alongside societal shifts were central in their regional extirpation by the 19th century, but the enduring cultural importance of oysters is maintained by aquaculture expansion. Informed conservation practices can be developed from reconstructing the temporal interplay between human societies and the natural environment.

: Macrobenthic biodiversity in the rocky intertidal areas of the Tae-an region, Republic of Korea, has decreased since the Hebei Spirit oil spill in December 2007. We aimed to investigate ecological roles of Pacific oyster (Crassostrea gigas) because recruitment and growth of oysters are critical to the recovery of damaged rocky shore ecosystem. We surveyed two sites monthly: natural rocky substrate and farming substrate, from July 2012 to January 2013 to identify and compare the changes in macrobenthic fauna. The abundance of young oysters was higher at the natural site. On the other hand, the mean height of oyster on the farming substrate was more than twice as great. The abundance of oyster at the natural site increased until October and then continuously decreased until end of study period. However, the abundance of oyster at the farming site constantly decreased from the beginning of study period. These different growth patterns might be attributable to spatial competition between oyster and a barnacle species (Balanus albicostatus) and environmental factors. At the natural site, physical stress factors including dramatic temperature changes and desiccation a few of the major factors limiting growth during aerial exposure. In addition, motile macrobenthos could be detrimental to oysters because they interrupt filter-feeding activities and hence hamper the growth of oysters. We show the higher recruitment of oysters at the natural site and healthy growth in the farming substrate are due to complicated differences in physical and biological stress factors.

Oyster reefs have important ecological functions and environmental service values, such as filtering water, providing fish habitats, maintaining biodiversity, and carbon sequestration. Oyster reef recovery has become one of the most important means for fishery resource conservation and ecosystems restoration of coastal regions . C. sikamea and C. ariakensis are two important reef oysters along the coast of China. However, it is very difficult to identify the larvae of these two oysters. To solve this problem, we developed two pairs of novel species-specific PCR primers for identifying these two oysters. The forward C. sikamea -specific primer is Cs-F: 5′-CGAAGAGGGGCATGATAAATGAGG-3′, and the reverse primer is Cs-R: 5′-ATATGAACTTCTCCAACCTCCCC-3′, both of them within the scope of mitochondrial ND5 gene. The forward C. ariakensis -specific primer is Ca-F: 5′-GGGCAAATAAAAGGCAAAACCC-3′, located between tRNA ser and tRNA pro , and the reverse primer is Ca-R: 5′-CATAAACTTCTGCAAGACTCCC-3′, lies between tRNA pro and small subunit ribosomal RNA (ssrRNA). These two primers can identify the larvae of C. ariakensis and C. sikamea from other oysters rapidly and effectively, with extremely high accurate rate (=100%). This molecular identification method does not require prior sorting of larvae. These two specific primers are good contribution to molecular identification of C. sikamea , C. ariakensis and other oysters, and could be a useful tool for oyster larvae identification and ecological restoration.
