| 报道了2003年5月1日～6月25日在玉环县东方海洋生物 有限公司育苗厂80 m2的水泥池中育出平均体长2.34 cm的双齿围沙蚕(Perinereis aibuhitensis Grube)幼体13.16kg,并对双齿围沙蚕疣足幼虫进行了不同生态条件的单因子试验。结果表明,适宜的温度为 24～26℃;盐度的适合范围为15.0～34.8,最适21.6;饵料以球等鞭金藻和混合藻(角毛藻+扁藻+微绿球藻)为佳,球等鞭金藻的密度以 20×104个/mL组效果最佳;4刚疣足幼体起投细砂效果明显优于其它组。 |

| Abstract: |
| 13.16 kg larva of Perinereis aibuhitensis Grube which average length was 2.34 cm had been bred in 80 m2 concrete pool Orient Halobios Corporation in Yuhuan country from May 1st to June 25th in 2003. Different conditions of zoology odd-gene test were carried out on larva. The result indicated that the condign temperature was 24～26 ℃; the condign salinity was 15.0～34.8, the best of all was 21.6; the condign feeds were Isochrysis galbana, the commingled algae(Chaetoceros sp., Nannonchloris oculata and Platymonas subcordiformis), and the best density of I. galbana was 20×104 cell/mL; The larva having 4 arthromeres and throwing thin sands makes the livability and metamorphosis rate of the larva higher than those of other groups of larvae. |
