Salinity tolerance range (?) | Exact range: 15 - 25 References: Wang, T., Li, Q. 2018. Effects of salinity and temperature on growth and survival of juvenile Iwagaki oyster Crassostrea nippona. Journal of Ocean University of China, 17, pp. 941-946. Hu, L., Zhang, Z., Wang, H., Zhang, T. 2018. Molecular phylogeography and population history of Crassostrea sikamea (Amemiya, 1928) based on mitochondrial DNA. Journal of Experimental Marine Biology and Ecology, 503, pp. 23-30. Comments: C. sikamea, salinities higher than 25 had significant negative effects on the larvae development and growth. A salinity range of 25–30 is the optimum salinity for the growth of juvenile. Suitable range for C. sikamea growth is salinity 15–25 psu. |

Comments: C. sikamea, despite its smaller size, has gained popularity in the United States for its excellent flavor, temporarily replacing C.gigas imports. C. sikamea presents new opportunities for China's fishery economy. |
