| 英文摘要 | 通过文蛤幼体对几种单胞藻的摄食及饥饿实验，研究了几种单胞藻的饵料效果及适宜投饵密度，幼体营养贮存饱和点（PrS）和幼体发育变态不可恢复点（Pnr）.等边金藻和扁藻为文蛤幼体的适宜饵料，混合投喂效果更佳.饵料的适宜密度为：扁藻0.5~1万/Ml，等鞭金藻2.5~5万/Ml，混合投喂（金藻＋扁藻）（1.25＋0.5）万/Ml.老化金藻藻液对幼体的生长发育有限制作用.文蛤幼体的Pnr和PrS50各为5d左右; The diet eFFiciency and optimal concentration of two species algae, the PNR(Poit of No Retern) and PRS(Pont of Reserved Saturtion) of Meretrix meretrix larvae were studied during a Feeding and starvation experiment. Isochrysis galbana and Platymonas sp. were suitable Food For larvae culture.The larvae grew more rapidly when Feed on mixed diet.The optiomal concentration of algae For larval culture was 0.5×10 4 cells/mL to 1×10 4 cells/mL For Platymonas sp., 2.5 (2.5+1)×10 4 cells/mL For mixed diet Isochrysis galbana + Platymonas .The metabolic products of Isochrysis galbana had an inhibitory eFFcet on larval growth and aged Isochrysis galbana might kill larvae.Both of PNR and PRS 50 is about 5 days For larvae. |
