试验结果表明 ,采自盐度 16水体中的才女虫 (Polydorasp .)幼虫 ,其 2 4h存活盐幅为 40～ 3;采自盐度 5水体中的才女虫幼虫 ,其 2 4h存活盐幅为 15～ 3。盐度 16水体中的才女虫幼虫经过逐步驯化后 ,盐度生态幅增大 ,其 2 4h安全存活盐幅为 5 0～ 2。
The test results showed that the larvae of Polydorasp. Collected from the salinity of 16 water bodies had a survival breadth of 40 to 3 in 24 h; the larvae of larvae collected from salinity 5 water bodies had a survival breadth of 24 h 15 ~ 3. Salinity 16 in the water female larvae after gradual domestication, the salinity ecological amplitude increases, its safe deposit survival rate of 4h 50 ~ 2.
