“…Therefore, replacing microalgae with a substitute with the same nutritive qualities has been attempted for pearl oyster. Since 2015, the effects of artificial diets on survival, growth, biochemical composition and expressions of mineralization genes of P. fucata martensii have been investigated (Yang et al 2015ab;Wang et al, 2016). The present results showed that there were no significant differences in pearl production traits among the groups separately fed with three different diets (P. subcordiformis, P. subcordiformis+D4 and D4).…”

“…We have attempted to develop artificial diets for pearl oyster and analysed the physical and chemical properties of the diets (Yang et al., ). Moreover, we have evaluated the effects of artificial diets on growth performances and gene expression levels of juvenile and adult pearl oyster (Wang et al., ; Yang et al., ). Here, we report the effects of replacement of dietary microalgae with artificial diets on pearl production traits, growth and biomineralization‐related gene expression in pearl oyster P. fucata martensii .…”

“…Researches on the nutritional requirements and artificial feed of bivalve molluscs are relatively more laggard than those on other aquatic animals (fish, shrimp and crab) . A few studies have reported the development of artificial diets in several bivalve species, such as microalgal concentrates (Brown & Robert, 2002), spray-dried microalgae (Arney, Liu, Forster, Mckinley & Pearce, 2015), single-cell detritus production from seaweeds (Tanyaros & Chuseingjaw, 2016), yeasts (Nell, Diemar & Heasman, 1996), microcapsules of varying types (Chu, Webb, Hepworth & Casey, 1987;Knauer & Southgate, 1997;Numaguchi, 2002;Numaguchi & Nell, 1991), bacterial proteins (Philippe & Christopher, 1994) and formulated diets (Gui, Kaspar, Zamora, Dunphy & Jeffs, 2016b;Gui, Zamora, Dunphy & Jeffs, 2016a;Mamat & Alfaro, 2014;Nevejan, Davis, Little & Kiliona, 2007;Nevejan, Pronker & Peene, 2008;Wang et al, 2016;Yang, Luo, Wang, Deng & Du, 2015a;Yang et al, 2015b). However, no artificial feed has been commercially and biologically reliable to substitute for live microalgal feed for pearl oyster.…”

The effects of replacing dietary microalgae with artificial diet on pearl production traits and biomineralization‐related gene expression were investigated in pearl oyster (Pinctada fucata martensii). Three experiment groups (EG1, EG2 and EG3) were set. EG1 and EG3 were separately fed Platymonas subcordiformis and artificial diet (D4), respectively, and EG2 was fed with mixed P. subcordiformis and D4. A control group (CG) was cultured in natural sea. All groups were continuously fed for 150 days. The results showed that the survival rates of EG1, EG2 and EG3 were significantly higher than that of CG. No significant differences in retention rate and pearl thickness were observed among the four groups, but CG had the lowest values of both parameters. The relative expression levels of EGFR and FGF18 mRNA did not significantly differ among EG1, EG2 and EG3. Moreover, the relative expression levels of GHITM and TβR I mRNA significantly varied among the groups and EG3, and EG1 had the highest and lowest relative expression levels of GHITM and TβR I mRNA respectively. The relative expression levels of nacrein and chitin‐binding mRNA significantly differed among the groups, and EG1 had the lowest expression levels of nacrein and chitin‐binding mRNA. No significant differences in the relative expression levels of MSI60 and TIMP mRNA were observed among the groups. The results suggested that D4 can replace part of microalgae, which is helpful for further studies on developing artificial diet of pearl oyster.

“…The pearling industry peaked with an annual yield of 20 metric tons in the 1990s, but harvests are currently declining due to the reduced growth of cultivated stocks, mass mortality, and a decline in environmental conditions (Qiu et al 2014). Some attempts have been made to improve pearl yields since 2000, including strain development ) and the improvement of culture methods and procedures (Deng et al 2011;Yang et al 2015;Wang et al 2016).…”

This study evaluated the influences of age on the pearl production performance and innate immune responses of the pearl oyster Pinctada fucata martensii. Two age‐groups (group A: 1.5 years of age; group B: 2.5 years of age) were subjected to a nucleus insertion operation. The immune‐ and antioxidant‐related enzymatic activities and expression levels of immune‐related genes in both groups were evaluated 3 d after the nucleus insertion operation. The survival rate, retention rate, and biomineralization capacity of the groups were examined when the pearls were harvested. The results showed that the activities of alkaline phosphatase, acid phosphatase, superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPx) and the expressions of the SOD, GPx, heat shock protein 70 (HSP70), and HSP90 genes were significantly higher in group A than in group B 3 d after the nucleus insertion operation (P < 0.05). Group A had a significantly higher survival rate than group B at 3, 7, and 30 d after the operation and at harvest. Group A had a significantly higher retention rate and pearl thickness than group B at harvest. The expression levels of the biomineralization genes for nacrein and pearlin were significantly higher in group A than in group B (P < 0.05), whereas expression of the biomineralization gene for Pif‐177 was significantly higher in group B. Collectively, these results suggested that 1.5‐year‐old pearl oysters have better pearl production performance and innate immune response to nucleus insertion operations, so selecting young pearl oysters to use as host and donor oysters shows promise as a process for improving the quality of cultured pearls.
