摘　　要：Experiments on salinity tolerance of embryos and larvae of the southem bay scallop Argopecten irradians concentricus Say under controlled temperature of 28℃ showed that although the eggs were fertilized and cleaved at salinity 18.1 -37.4, they could further develop into normal D-shaped larvae only at salinity 23.4-36.1, while the trochophore larvae could develop into normal D-shaped larvae at salinity 22.1 -39.9. For 72 hours , the larvae could tolerate salinity of 18.4-43.9, the salinity favoring growth was 19.8-42.4; the suitable range was 21-36, and the optimum at about 28. They metamorphosed at salinity 18.9-43.5, optimally at 24-32.Experiments on salimity tolerance of embryos and larvae of the southern bay scallopArgopecten irradians concentricus Say under controlled temperature of 28°C showed that although the eggs were fertilized and cleaved at salinity 18.1–37.4, they could further develop into normal D-shaped larvae only at salinity 23.4–36.1, while the trochophore larvae could develop into normal D—shaped larvae at salinity 22.1–39.9.
