摘要
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80m^2的水泥池中育出平均体长2.34cm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;饵料以球等鞭全藻和混合藻(角毛藻+扁藻+微绿球藻)为佳,球等鞭金藻的密度以20×10^4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。
13.16 kg larva of Perinerei.+ aibuhitensis Grube which average length was 2.34 cm had been bred in 80 m^2 concrete pool Orient Halobios Corporation in Yuhuan country from May 1st to June 25th in 2003. Different conditions of zoology odd-gone test were carried out on larva. The result indicated that the condign temperature was 24~26℃ ; the eondign 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 L galbana was 20×10^4 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.
