“…The heritability of Zn content was 0.02 ± 0.02, which is very low, and a t test indicated no significant difference from zero, which is consistent with other studies, demonstrating that heavy metal content is attributable to the environment and unrelated to heritability (Lee et al, 2015;Richards & Chaloupka, 2008). In contrast, Camara et al found that the heritability of Zn was moderate for 3-year-old oysters and was positively related to growth-related traits, which may indicate that heavy metal accumulation progresses together with oyster aging (Camara et al, 2005).…”

Pacific oysters, Crassostrea gigas, are the most abundantly harvested shellfish in the world and are ecologically significant. The content of nutrients, including protein, glycogen, lipid, zinc (Zn), and selenium (Se), is important for oyster meat quality, but heritability estimates of such traits have rarely been reported. In this study, 64 full‐sib families were generated using a nested mating design. Finally, 18 full‐sib families, of which there were nine half‐sib families, with each containing 2 full‐sib families, were sampled for heritability estimates. The narrow‐sense heritabilities of glycogen, protein, lipid, Zn, and Se contents were 0.29 ± 0.02, 0.38 ± 0.02, 0.58 ± 0.08, 0.02 ± 0.02, and 0, respectively. Negative genetic correlations existed between both glycogen and protein content (−0.95 ± 0.004) and between lipid and protein content (−0.59 ± 0.05), whereas a positive correlation was observed between lipid and glycogen content (0.16 ± 0.06). Weak genetic and phenotypical correlations (r = 0–0.2) were observed between shell height and nutritional quality traits. These data demonstrated that glycogen, protein, and lipid content can be chosen in a selective breeding program, but glycogen and lipids cannot be selected together with protein. Furthermore, performing indirect selective breeding for quality traits by selecting traits related to growth is impossible. This study provides information for the development of breeding strategies for oyster quality traits.

“…However, oysters containing high levels of trace metals are dangerous for consumers. Therefore, determining trace metal concentrations in oysters is of the utmost importance (Lee et al 2015;Weng and Wang 2019).…”

Cd, Cr, Cu, Pb, and Zn concentrations were measured in oysters (C. gigas), plankton, and seawater during spring, summer, and autumn in Liaodong Bay (Bohai Sea, China) to elucidate the effects of season, region, and oyster size on metal bioaccumulation in oysters. Metal concentrations were quantified via atomic absorption spectrophotometry. Our study determined that metal concentrations in oysters, plankton, and seawater were the highest in summer, whereas the lowest levels occurred in autumn. Regarding oyster sizes, the highest Pb levels occurred in C3-sized oysters (> 5-cm length), whereas the highest Cd, Cr, Cu, and Zn levels occurred in C2 (3–5-cm length) oysters. In contrast, the lowest Cu and Pb levels occurred in C1 (< 3-cm length) oysters, whereas the lowest mean Cd, Cr, and Zn concentrations were observed in C3 oysters. Significant differences in trace metal concentrations in the three sample types were observed in all sampling sites.

“…As a result of two decades of research on trophic transfer of metals, dietary exposure is now considered a major route for metal accumulation in marine animals, including both invertebrates and fish (e.g. Casado-Martinez et al, 2009;Lee et al, 2015;Zhang et al, 2011). Experimentally determining uptake and efflux rates, as well as assimilation efficiencies, allows contamination responses of wild aquatic organisms to be modelled using environmentally relevant metal concentrations.…”

“…punctalata (benthic diatom), were cultured in bulk at adjacent CSIRO Land and Water laboratory under the same laboratory conditions in which the organisms in this experiment were kept. Algae were radiolabelled following a procedure adapted from Lee et al (2015) (Supporting Information S4). Algae labelling metal concentrations were chosen with the aim of obtaining high enough radioactivity levels in the clams while ensuring that most of the algal cells remained alive and growing during the feeding exposure.…”

“…Acid-extractable sediment concentrations (Cd = 0.1, 1, 3; Mn = 50, 100, 500; Zn = 10, 100, 500 µg g -1 ) from these estuaries were used (Brady et al, 2015;Twining et al, 2008). The acid-extractable metal fraction was used because it better represents bioavailable metal than the total recoverable metal concentrations (Lee et al, 2015).…”
